1989 f250 eec
swapped motors (351w) and now cant get the new one to start. fuel injection is not working. checked everything i can think of. question the motor was out of a truck with standard tranny. mine is an auto. would that cause any problems with the computer? thanks

Computers are vehicle, year and equipment specific. Change the engine without changing the computer, or even swapping parts around...the vehicle may not run correctly, it may not run at all. It all has to do with the Calibration Code. There are over 300 different CC's from just the 1980's F Series trucks...and you'll have to find one that matches the application, unless someone has come out with something aftermarket that I'm not aware of.

To the OP.. you'll have to give us more information. What have you changed, what did you check?

Conanski = that may be true for some vehicles, but not all. Plus, I'm in CA, where things can be radically different than what the 49 state vehicles used inre to computers and CC's. Bottom line, this is a good example of planned obsolesence.

everything on the engine was there and just plugged in . the problem i have is ive got no pulse to the injectors. i've changed distributor twice to check the pip and module. ive ran down all the grounds to the computer and ive checked every wire that i can find. cant find anything wrong. the only thing out of the ordinary about this engine change was when i went to start the motor the battery was dead. this a good battery and should not have lost its charge. i had the positive disconnected. im thinkink possilbly i could have grounded the battery to the chasis. causing a surge back to the computer. i dont know if thats even possible though.

Do you have spark?
Check the key on - engine off codes and report back. See www.fordfuelinjection.com to see how to run a diagnostics self test.
