I have a 2006 crown vic cop car that I stripped and put a truck body on. The crown vic was a running driving car before I stripped it, no cel.
Here's a list of things I have. A motor that will crank, a cluster that seems to function, the tach bounces while spinning, constant 12v power to my injectors but theyre not fiiring, all good fuses and relays. I shortened the main harness so it would fit under the hood one wire at a time. A computer that I sent out to have turned into a stand alone computer with a 93 octane tune. A functional fuel cut off switch. Last but not least a no start situation.
Here's what I don't have. A fuel pump (verified it does work with hot wire), no digital odometer read out, communication to the OBDII port that is of any use to diagnose. I have verified fuses, relays are good.
I have tried cranking and spraying starting fluid with no luck. When I did the swap I did not touch the engine harness at all, that stayed in place the whole time. I did do some welding on the chassis but the battery was out and nothing was plugged it at that time.
The engine is bone stock, I have no plans to do anything to the motor or transmission.
I drove the car to the spot I tore it down. Put everything on top of the chassis and back together again. I had the same result before I had the computer flashed as I have now. I figured having it flashed to make it a stand alone unit would resolve any issue I may have been having.
I have 12 volts at pin 35 and 36 with key on at the pcm with key on.
I have 12 volts at obdII 5 and 16.
I have computer ground on 47, 48, 49 and 50.
Continuity reading 3.7 between 6 and 14.
Continuity reading 0.00 on Pcm connector pins 11 and 23.
I'm bashing my head off the wall trying to figure this system out so the thing will run. I'm open to ideas and places to look.

I got my hands on a better scan tool than what I was using. I'm showing a P1233 - fuel pump driver module offline. I also have no spark still. But I do have a constant 12v at the injectors. |
