Congrats for using the test light instead of a pocket full of fuses.

NOW WHICH FUSE?? F 6? We gotta know!
I dont see a connection to the ICM from the F 6 FUEL pump fuse on the 94' similar schematic.

The ICM wiring goes to a mid engine connector usualy under the alternator. Then on to the firewall on passenger side.

If you have no spark with the F 6 fuse disconnected you have other problems.

I havent heard of alot of ICMs going bad on this forum or others. Often the ICM is targeted for troubleshooting since it is a most logical component. More often the CRANKshaft sensors and coil packs. However, since it's targeted so quickly it may avoid forum attention. Coil packs cause rough running and the CRANKshaft sensor causing jerks at speed, complete stalls or CODE 41.

The fuel pump relay CONTROL (coil) is connected directly to the ECM.. D16 pin connection. Its suppose to.

The Voltage circuit for the running fuel pump comes through Fuse 6 then off to two places at the same time.
1. First to the oil pressure switch then direct to the fuel pump. Basically, with no oil pressure it wont let the engine run by cutting off fuel. It provices source voltage when pressure is up then the fuel pump completes the circuit to ground.
2. The other place is the other side of the relay for PRIME when the engine is first turned on without oil pressure. You normally will see the test light light because it can find a ground until the fuel pump relay is energized..

The F 6 Fuse ONLY has circuits for the fuel pump, oil pressure switch, and fuel pump relay. Those and associative wiring can blow the F6 fuse.

Know whats going on when using a test light to test for ground on a normally end grounded circuit through a component.

Disconnect you fuel pump and use the test light.

I have heard of pinched fuel pump wires close to the tank.


Good luck.
