Hey, I'm new to the forums. I have a '91 3.1L V6 and can't get it started. It died on me while I was driving on a highway. The engine is getting fuel and the Plugs are firing but won't start up. Can anyone explain how to read the codes that is not as vague as the FAQ? My "Check Engine" light flashes but I don't understand what code it coresponds too.

 

well what is the code that is flashing i have a book to look them up for ya...i know off the top of my head number 53 is EGR code....if you need to flash the code cross a and b on the terminal and the engine flashes the code and haynes / chelton books have a section to tell u what the code means..just in case u have on

 

This is what it does: Flash, Pause, Flash Flash; F,P,FF; F,P,FF; F,P,FFF; F,P,FFF; F,P,FFF; then it starts with the two flashes like the beginning and repeats, then repeats the 3 flashes, and this sequence repeatsover and over. That is the part I don't understand. Thanks for your help

 

that would be two different codes if i am correct so it should be a 12 and 13 engine code. i will post what the haynes says to look at for these codes.......i am at my g/f house right now and the book is at my house....

 

okay well the 12 flash is a no refrence pulse if i remember correctly...13 means o2 sensor is staying lean.....which doesn't help....enless it is running so lean that its not getting gas....so next question is where did you check to make sure you had gas?.....if you just smelt u might want to check again...might be the sorce of your problem... just for refrence online for codes at this site http://www.thirdgen.org/service-engi...ht-error-codes

 

I pressed the nozzle behind the engine where you can attach a fuel pressure gauge. Also, after trying to crank the engine, I pulled the plugs out and they were moist with fuel.

 

I think it might be the crankshaft sensor. Does anyone know where it is located on the engine? I can't seem to find it

 

Go to an auto parts store and rent an ACTRON OBDII reader. What a great tool, I purchased one awhile ago and would not be with out it. It will tell you (in english) and code # what is going on.

my guess: your fuel pump died
