Re: 1988 Park Avenue Won't Start
Proms? .. most likely its ok..
even the PCM may be fine.
But as you say its one of the only things left you haven't changed and would have to suspect it.
I dont see individual relays for the injectors..
Not sure if you get pulses till its running.. I know perhaps it should get a pulse just when turning to start.. as a prime..
The injectors pulse from the PCM.
Wires going back to the PCM theres a Bulk head connector..Might be there but if you got a flash says theres some kind of connection.
Cam sensor tells the Ignition Module.. the ignition module tells the PCM,
The PCM outputs on these wires to the injectors.
1- Black
2- Green
3- Pink
4- Red
5- White
6- Yellow
the PCM goes out to a Bulkhead connector.. the wires then spread to the injectors.. the injectors (Brown wire) have a common #7 fuse in the relay center assembly.
UNDERSTAND the PCM provides the GROUND pulse for the injectors.. the gray wire should be hot in run position on the ignition switch.. if the fuse 7 is ok in the BODY relay center.
The fuse 7 source OF POWER is on your ignition switch and since your starter turns that power is working and ok there.
Perhaps you have lost a ground to the PCM.. BLACK WHITE wires to the PCM on D6.D7, D1 on the PCM.
.
Good Luck.
