I just did a engine swap in my 1991 and now it won't start it cranks and wants to run but it doesnt stay running when i have the gas pedal to the floor it barely starts and stays running for maybe a minute then dies i don't know what the problem is and need help
we are gonna need some more info. what swap did you do? that would be a good start. but it could be a number of things and you will just have to go down the list and check things out to narrow the problem down until you figure it out. checking for ecu codes would be a good start. checking fuel pressure. ignition system and timing. could be many things is all I'm saying hard for us to figure it out with out some info from you as you check things out. it also could be as simple as a missed ground wire! like the common ecu to t-stat housing. or in the wiring if you had to do any extra wiring for your swap. lots and lots of things lol.
