I think you got the rear relay terminals mixed up. 30 and 86 should be 12V key on. 87 and 87A on relay are the switch pins. 30 is the common. That is standard relay configuration
Hold on.
16 and 38 on ASD are good.
On the back fuel pump relay 85 is 12V? 85 is ground and goes to PCM through pin 3 of the fuse/relay block.
So when you turn the key to the off position, then to run are you hearing the fuel pump prime for approx 2secs?
Bought some stamp numbers and stamp it yourself on a steel rail. Pick a clean area so the repaint doesn't look new.
Stamp just last 8 characters (not 6 numbers) or find the actually location of one and see what it stamped. They never stamped the whole number before but that could have changed.
No. where the ASD relay is that's the PDC (power distribution center).
The fuse block should be the one under the dash.
The fuse/relay block is the one in the back.
So with key in run position and all the fuses in,
Pin 4/relay 86 should have 12V juice. If not check fuse 10 as above.
Sorry on my phone and hard to step person through troubleshooting on messages.
Put key to run position you should now have juice at pin 4/ relay 86. Sorry missed that step.
Check fuse 10. Check it for 12V if you got no juice with key in run.
Then pull it out.
One side is 12V the other side goes to pin 4 / relay 86.
If you got 12V on one side then Check the...
Next step is check the for 12V on pin 4 of the fuse/relay block. That should be pin 86 on the relay. 12V constant too.
Pin 3 or pin 85 on relay is the ground that goes to the PCM. The PCM controls the ground of the relay but you got the ASD relay feeding 12V signal to the PCM too.
Understood that but the PCM controls the prime timer. So if it is not stopping the pump and him stating the PCM can't be read anymore, the PCM could be toast.
Yes verify fuel pressure at the rail but if the PCM is toast he's dead anyways.
Brake lights or rear running lights. You need to be clear on which one. Both sides, one side?
If during driving, probably going over bumps and shorting a wire/connection.
