hello ppl I swapped out a motor with a automatic trans out of a 99 bmw 5401 v8 with a junkyard motor that was a manual trans I used all wiring from origanal car it does not start cranks but no start no fuel no spark was wondering if because one motor was hooked to a manual trans and the other was hooked to a automatic would that cause any differance in sensors and what not. I used the manual motor in the automatic car
Did the supplier of motor say that it was a running engine?
Did you explain to them what you were planning to do with the engine?
Were there any electrical connectors that werent connected after the change?
Did you use the wiring harness from the new motor or the old motor?
The new transmission is a manual, but if you kept your DME from the original motor it might not want to start becuase the car thinks its supposed to be an automatic still and can tell something is wrong.
Did you make sure the engine worked before swapping it in? Junkyard motors arent the most reliable.
yes it was a running motor the wiring came with the new motor however I used the wiring from the car that I was doing the install in. The motor came from a stick shift car and I had to put my automatic fly wheel on it in order for it to work in my car. because my car is the automatic someone sad I had to do a EWS syn. because the battery was dis conected for a long period of time. other then that I`m lost the motor turns over fine and I had no problems with any wiring plugs being different.
