Hello,

New here..not new to auto repair but new to Porsche.

I have a 1987 924s, automatic...it had been sitting since 2004 in the NM desert. Overall though it has a good body and only had 87K on odometer.

Going thru the no start check list here is what I have done.

fuel spark air right..
1. Cleaned out gas tank completely added new fuel pump. cleaned out air box ensure no obstructions
2. replaced dme relay
3. completely removed POS $80 aftermarket alarm system that started going off as soon as I added a battery.
4. took off fuel rail and cleaned up injecters...spark plugs/wires looked good cap was iffy so replaced that.
5. Tested coil with omhs meter across and met spec
6. tested speed sensor and ref sensor at sensor ohms was ok...at the ecu plug coundt get voltage to show so iffy and tach wasnt jumping on start..replaced both sensors..tach now jumps

so now i'm still getting no spark...my spark tester inst lighting but its not led so may be an issue. i'm getting 12v at both termin of the coil when key in on position.

so Im thinking the DME ECU itself may be an issue. im sure sitting in the NM sun for a almost a decade wasn't too nice on any parts.

questions:
1. is the a way to test the DME ECU itself? its an expensive part to have rebuild or buy a new/rebuilt one and I dont want to buy a who-knows-if-its good one off ebay.

If I can be sure its a bad ecu than I can stomach the spend.

Any other ideas?

Thanks

Kris
