New fuel pump=problem?
What I had:
stock fuel pump
FMU
SAFC
b&M FPR
450 injectors
12psi
(Ran Great, no CEL)
Changed:
Replaced- stock fuel pump with boschur racing 190 fuel pump
Removed- FMU
Problem:
At full throttle in the higher rpm range it leans out and the map sensor CEL (code 3) comes on and it runs like crap. I tried adjusting the safc a/f setting and the fpr and nothing seemed to help. I also tried with and without the missing link which is suposed to prevent a map sensor CEL from coming on and tried two diff. sets of 450s to make sure it wasent and injector problem and also tryed a couple diff. ECU's. Any sugestions on what to do would help, thanks!
