Ok so yesterday i was driving my car and all of a sudden it acted all wierd and it went to super rich at idle and the above 2500 it would start to go lean. I got home popped the hood and seen that my fuel pressure was at 70psi i tried to adust the fpr and nothing with or without the vac line the pressure is still at 70psi. I checked for kinks in the fuel line and i didnt see anything. i changed fpr and nothing i removed the fmu and still the same. Im so stuck and i want to race this weekend any help please!!!!

My setup:

stock pump
stock injectors
fpr
jrsc
jrsc fmu

bump cause you need to go to the track this weekend come on someone has to have had a similar problem

 

ok changed main relay too and it didnt help

 

morning bump cuz i need help

 

Maybe fuel pump? I don't know, you replaced the fpr, took off the FMU... I don't know what else it could be that is making your fuel pressure go up that high. Maybe try replacing the fuel rail?

 

yea im going to see if i can get a differnt fuel pump in tonight

 

Did you find out what the problem was?

 

well i blew air through my lines and it cleared right up and its running good as ever i didnt change out the pump since i fixed the problem

 

lol, wow, I guess there was a blockage somewhere?
