Question : 04 explorer keeps shutting of wont start now?
used obd 2 scanner no error codes came up can start engine to check sensors. battery is fine engine does crank
had to drive vehicle about ten miles home engine shutt off about 4 times on the way home got into the drive way poped the hood then shut off again got my reader out couldnt get it started again
fuel filter changed out checked fuel pump out put looks like plenty of pressure dont have fuel pressure guage though. thinking possibly distrubtor. engine sounds like it want to fire but no go
Got the solution. bolt came loose and cut wiring harness shorting out the system.
Answer:
Spray starting fluid in the air intake and if it starts, you've got a fuel delivery problem like fuel filter or fuel pump etc. Check for good spark with the spark tester below.

Question : How to check DTC's for power steering on a 2004 Chevy Malibu?
I am trying to pull the DTC's for the electronic power steering on a 2004 Chevy Malibu (V6) and was wondering if the vehicle had a way to pull the codes without a scanner. I know that some GM vehicles require shorting 2 pins on the OBD connector, others have you hold the odometer reset button when turning the key on...
Right now, I'm getting a warning for the steering and am trying to determine whether this is a serious issue or something that I can fix / replace. I'd rather save the $100.00 to have the code pulled by the dealer.
Thanks!
Answer:
Forget the DTC's. If you have a Malibu with the electric steering take it to a dealer. This is not an item that a shadetree mechanic should be messing with. There is a history of problems with this system and they may even give you warranty if you yell loud enough.

Question : How to read codes on a 2001 dodge ram 1500 5.9?
Hello I am having a little trouble I have two scan tools one of which I just bought just for this purpose (autoxray ez scan 6000 top of the line for this company) that both tell me the vehicle is not responding when I try to read the codes on my truck. I have tested the port for power which it does have and have read many little statments online telling me others have been able to scan theres with just run of the mill scanners why cant I? my port has pins 3, 4, 5, 6, 7, 11, 14, 16 is mine missing a pin somehow? I ran fine yesterday and today get in and wont start unless I hold down the throttle and as soon as I let off it dies instantly like i turned it off. the fuel gauge also stopped working today with the check gauges light illuminated, I checked the TPS which is fine, the fuel rail holds steady at 50 PSI when u turn the key on. Also I hear relays clicking over and over every second or so, just about the same duration as the rpms dropping while holding the throttle open WHATS THE DEAL!!!!! Please has anyone encountered anything like this???? Thank you so much
I know its not empty i thought it was when the gauge stopped working so I put 10 gallons in and still nothing and the battery has never given me an issue
also I have tried my scanner on 2 other vehicles and it works fine on them, I have a chrysler enhanced cable and regular obd 2 cable and neither work, I called the company and ran through different configurations of the scanner and still nothing
Answer:
your not missing a pin ,make sure the scanner is working right by trying it on another vehicle,the re try it,you have to plug the scanner in then turn the key on to diagnose it,you shouldn't be having any problems from that one,you'll have to get the scanner working to diagnose it though,check the fuse for the computer in the fuse panel it may have blown,be careful about touching any pins together on that one you can damge something real easy ,good luck.

Question : Can a bad relay cause an interuption in OBD 2 port signals?
First off sorry for all the questions on the same subject but I am persistant when I cant figure out a problem. I have a 2001 dodge ram 1500 5.9 and cannot scan it with either of my 2 scanners and dont know why. I have no blown fuses, I have confirmed power and ground to the port operational but yet it still says vehicle not responding, I have tested both scanners on 2 other vehicles of different years and makes with no issue in scanning. Also I am told over and over there should be no reason I cannot extract the data, there IS a code as the engine light is on and the truck has issues just out of nowhere. Even if there wasnt a code it would just say no codes in vehicle not vehicle not responding. Dodge Man if you read this maybe you could permit me to email you about this problem you obviously know what your talking about. I am a mechanic so I can do whatever is needed to find the issue I am just at a loss here Thank you so much.
checked under the hood for a port cant find one also is there another fuse panel other than the one on the drivers side of the dashin between the door and side of dash?
Ok thank you everybody I am starting to suspect the PCM, Unfortunately I believe my scanner (autoxray 6000 about $5-600) is not sophisticated enough to communicate with anything more than the PCM. As much as I hate it I think I might have to have the dealer scan it for me ( I am kinda ticked at them I have only had the truck 3 months and have put under 1000 miles on it and has only 67k, and they wont help me out one bit) So am I correct in assuming IF it is the PCM then that is why I cant get anything out of my scanner? Thank you again.
Answer:
The first thing to do is to see if you can communicate with the other modules (abs, srs, body, etc, whatever shares the bus). The various modules communicate an a bus (network). If one module has a problem in can stop communication on the bus. If others work then you know the failure is pcm related, in none communicate then you need to remove one module at a time and try to communicate again. Without a scan tool that can communicate with more than the pcm you have to monitor the bus for activity(square wave pattern on a graphing meter), if there is none unplug modules one at a time until there is. This stuff can be pretty tough the first time around, a factory manual should have some comm bus diagnostics in it. You can find some info in all data or mitchell too.

Question : 2000 chevy blazer SERVICE ENGINE SOON!!! Please help?
ok so i started my 2000 blazer this morning to find service engine soon soo i pull out the ole' handy OBD II scanner and the code is P0143 O2 sensor low input... i say ok not too bad could be worse... soo i clean the connector to the particular O2 sensor because it had some corrosion and mud in it ewww. anyway soo i cleared the code and then i went out about 2 hours later and started it again and the light was back on (after driving it about 12 miles with no light) soo i checked again and this time it was P0103 MAF soo i cleared the code and drove again and neither came back PLEASE TELL ME WHAT TO DO? i already have WAY to much to fix on this vehicle and i cannot affort to get another car sooo i am kinda f-ucked.... are the sensors going bad could it have just been a glitch in the MAF for the P0103 i'm LOST!
Answer:
You're guessing. Unfortunately, there's no easy answer to your question. For example, your p0143 code shows a value out of range for one of the oxygen sensors. This could mean that the sensor is bad - but not necessarily. There could be an upstream condition from that sensor that is causing a lean or rich exhaust reading, which is out of the sensors range. The only way to determine whether or not the sensor is doing it's job is to test the wave form of the sensor itself (oscilliscope, scanner, etc). By comparing its readings to its acceptable values you can determine whether the sensor is doing its job or not. Basically, if this is beyond your ability, you'll need to take it to a tech you trust and have it properly addressed. Best of luck!

Question : How do you manually pull codes from a 1989 jeep cherokee?
My 1989 cherokee has been NOTHING but problems and frankly I am sorry I bought the thing. Nothing works right on it, I get 5 mpg, I have already spent over $2,000 in repairs (stupid on my part) Recently all the fuel injectors were replaces and it is running even worse. It was suggested to me that I take it to any auto parts place and have them do a code scan on it. Unfortunately I went to everyone in town. Big name ones such as autozone,napa,shucks they all said there is no such code scanner for the vehicle and that I would have to pull the codes manually. Being not very happy I left with out finding out how to do that. Any ideas how? I hope it doesn't cost anything. I am not sure how much more I want to spend on this. I want to get rid of it but according to NADA with the condition it is in I am looking at $250.00 trade in. $250.00 is not worth my time.
A 1989 Jeep Cherokee uses the renix system therefore no codes are stored or "thrown" You would have to hook it up to what is now basically an obsolete machine and get the codes in real time. Wish I would have known that before :-)
Yes it is a pos and I would't sell it to my own worst enemy. not because I want the thing anymore but because I am not that mean.
Thanks but there is not a digital odometer. I
Answer:
Lots of things can cause the problems you describe and blaming the vehicle because you followed bad advice doesn't seem quite right either.
Bad gas millage can be cause by improper air pressure in the tire, clogged catalytic converter, damaged/restricting exhaust, fuel injectors (assuming your Cherokee is actually fuel inject, some of them were carbonated) Carb problems, dirty air filter, bad O2 sensors, clogged fuel filter... the list goes on.
for OBD-I-era computer for these codes, put the key in the ignition and turn the key to run (not start), then off, then run, then off, then run (that's 3 runs and 2 offs). Leave the key in the run position.
The check engine light will turn on for a few seconds, then turn off, then (sometimes after 20 seconds) start flashing. The flashes are counting out 2-digit trouble codes. Fast flashes count up each digit, with a longer pause between digits.

Question : Whats wrong with my Honda?
its a 99 Honda Accord LX with a 4 cylinder F23 Vtec engine and 121,000 miles in it. While moving it abruptly shuts off and sometimes back on. Thinking it was a fuel problem i changed the fuel cap and the fuel filter and pump. I contacted my local Honda dealer to find out if any recalls where done on my vehicle. All the recalls that existed have already been done according to the dealer (including the ignition switch). The scanner is not giving any codes. Any suggestions will help. Thanks!
Answer:
it could be numerous of things...such as they stated the grounding wire...fuel relay...or just your ignition system (cap and rotor, spark plugs and wires, or maybe the whole distrubitor....maybe even your fuel injectors being dirty...
