Wassup so here it goes...I just recently swapped out my 00 Maxima with a 01 engine due to the engine blowing up on me... I get everything 2gether and the car turned,on but turned off.. I change all cam sensors and the crank sensors and now car turns in with no problem..now here's my problem..when I try to start it...the engine gets flooded with fuel And car don't turn on... If I take out the fuse to the fuel pump car starts right up and I put fuse back and everything is fine..car runs great until I turn it off..and then I have 2 take the fuel pump fuse out and restart the car...then also I think the crank sensor in the back is reading to high and is causing the car to idle to high atleast that's watt I believe.... Like I said the engine is a 01 in a 00 shell with a 00 ecu.. Could there be a problem with the computer our something that it has to be reprogrammed..or do I need a 01 computer...I don't no what more to do... I need some help....ive done all I could do 2 my knowledge...id appreciate some input/advice..
