EFI Codes
I have an EFI starting and running problem.
S/N OK005833 454 MPI MEFI 1
Trouble code 42 ignition control and code 33 MAP
Here is what I've done so far, I cleared the codes and replaced the Distributor and the map sensor,the codes reappear without starting the engine, had both parts on the shelf and the other engine the ECM stays powered up with the key off but it kills the engine and all of the gauges are off when you turn the key off.
Anyone have any ideas?
