if you can get a scope, check the waveform on the sensors as you're cranking. i think it's a sine wave of +-3 but i have to check when i can access my manual. lol, i seem to have forgotten the URL to my own site...

edit: got it, check below. if you need any other troubleshooting procedures, let me know and i'll post em up.

Thanks

Andrew- Car's looking great dude.

The injector harness gave Jason a no start issue- was also a harness short.. worth a serious look.

Same thing happened to me. Get a DME from a friend and try it. The DME obviously seems to have gone bad.....they do over time. I spent over $500 on Ref Sensors/coil/plugs/wires/relays/etc.....then bought a used DME off EBAY for $150, and with one turn of the key, it started right up!

I'm gonna pull the dme and resolder every connection. Gotta rule that out.

next- ref and speed sensors. then recheck all the belts.

"The no spark issue is not normal.".. nice quote.
