what wrong with my car? code reader read 91 on but didn't tell me what it mean
I had new fuel pump on it and got it start up and had it running for 10 min.then it just shut
off by it self. then I try to start it again.it would crank start then shut off..
I think you should check the crank sensor. I just replaced my fuel pump w/same problem. Was told it was crank position sensor. Now trying to find out where mine is located.
Button front engine....good luck
Code 91 is not a valid OBD II trouble code. The code will begin with the letter "P" then four digits. For example P0300. HTH. -Jim
check ur fuel pressure regulator really need all of the P code to help out any more.
