Electrical (?) fault, late 944 8v

[BananaClip]

Got another one for y'all. I just went in and did my sparkplugs (they were abysmal- pics later) and found a loose heatshield under the exhaust manifold. I wiggled it, and the engine died. There was a conduit underneath it with two blue wires and one white wire with a yellow stripe. The two blue ones run to the oil pressure sender, and the white/yellow runs back under the motor somewhere. Any chance that bad boy runs to the fuel pump or something that has to get a signal in order for the fuel pump to run?

It must be thoroughly grounded now because it cranks just like the DME relay has been pulled (tried that too-- no change). I'm really not entirely sure how to replace it even if that wire is the problem.

e: If I've fried the DME, please let me down gently.

The white wire with yellow stripe may be the "low oil indicatior" lamp lead to the instrument panel.

Try a different DME/fuel pump relay or do the "jumper" on Clarks-Garage.

Cross your toes and hope it is not the ECU/DME. The '88 (944 & 924S-mine) uses a semi rare DME
944 618 121 05.

Usually priced at $200 and up used if you can find one.
Testing is usually $50 at SpecializedECU on the web. Repair with 5 year warranty is $500 or so???

Are you sure you did not mix up the spark plug wires or the cap connection?
What else did you work on?

Is the battery POS connection tight and the small 3 wires connected snugly--one goes to the DME for power.

Good Luck,

I cleaned up the battery terminal, and it's starting again. Voodoo.
