Problem: Car would die 2 sec after started.
three wires on the grey connection were shorting out together.
the fourth one was cut and connected to the temp sensor.
I did several tests like: spark test from plugs 1,3,4 strong
#2 kinda weak. Fuel pumps test with light tester...turned car
over and the light would come on then go off. Fuel pump relay?
After being fed up with the car after the 4th hour of tinkering.
I pulled the ignition harness and the engine harness.
The red wire that goes to the Alt was about to short out by
the pully system. I was checking the ignition wire tonight and
noticed at the plug in part that it was full of grease...?
Along with the icu box as well. Could that have killed the car?
Spark plugs #1,3,4 were srong....Please help bricksters

Sounds like you need a engine wire harness call me or email me at 818-708-7052 or ufarley@earthlink.net I can get you one in excellant cond. very reasonable tested and clean replacement harness from $120-180

The plugs are greased to keep water out, that's ok.

On these cars, if the alt small red wire grounds to the block, the car likely will not run, and may have all warning lights on all the time, or none at all even when not running.

Fix that wire first and foremost. I had an 86 with that wire repaired, re-routed around the right side and thru the strut tower, with good quality 20-gauge teflon wire. I drove it 50K miles that way, no problems even though it had a crusty wiring harness. Keep a bit at the plug to splice onto, that pin is a special kind of item.

Once its back together, check for spark by pulling the coil wire off the dist. I tuck it in by the left hood hinge, so I can see it while I turn the key. Should be good strong blue sparks. If that's ok, you now move on to the 25A fuseholder behind the battery (main power to fuel pumps, computer, and injectors), and then to the fuel pump relay (under right side of dashboard, near firewall, white box). Replace it or grab a couple junkyard spares. Or a new one: P/N 3523608. Always carry a spare.

Good luck!

Even though the fuel pump is running, you don't know if getting too little or too much fuel. See if you plugs are wet (fuel flooding); if so check fuel pressure regulator and coolant temperature sensor. Otherwise it could be the fuel check valve sticking. See the FAQ section of brick board for more detail and how to check.

Hope this helps
