FPR issues

[Ak_DSMER]

since i replaced the 390cc injectors with 450cc and swapped the 5-speed ecu it still wont idle right and it takes a minute or so to get it started in the morning also it doesn't like being under a load and im wandering is it just the fpr that is causing this.

How did it idle and start before you swapped?

when i brought the car i didnt have a key but i was told it idled fine 2 of the 390cc injectors were leaking and i just so happen to have 450cc right there and the 5 speed ecu

Only test i can say is to pull off the small vacuum hose on the fpr while the car is running or has fuel pressure built up and see if fuel comes out of it, if it does the fpr is bad. or the ecu temp sender is bad for those hard morning starts.

no fuel came out of vaccum line what is this ecu temp sender is it a sensor.
also the psi in the auto fpr's is different from the 5-speed fpr's right

 

[ilco187]

n/t 47 psi
auto turbo 42 psi
turbo 5 speed 36 psi
