hi i am shannon i will help on this issue.
do you have a test light?
do you have a volt meter ? i can get you a diagram . and help with testing . just let me know if you want my help. just post back.
i have seen this before new engine installed and the ECM B fuse blowing. most likely the wire for the oil pressure switch has got pinched at the bell housing between the engine and transmission. the ECM B fuse powers the fuel pump.
if this info answered your question then please press the ACCEPT button .thats how i get paid.i will still answer on this issue just ask fallow on question. thanks shannon
if you look at the last diagram i sent you will see the ECM B fuse powers the fuel pump and the ECM .i don,t know what changes have been done to the wiring system . but if you are not using the fuel pump relay or oil pressure switch . i would start their.
