Ok After posting in over 10 forums about this issue i have yet to find a Viable answer. I have a 87 N/A 5 Spd with no spark no Tach signal and no idiot lights. I have done all Diagnostics properly i have replaced The Cas, The coils both trailing and leading twice, Replaced the Entire dash Harness replaced, the Ecu 3 times last one came from a running S4, Replaced Every fuse with new ones. replaced the Main Relay under the Trailing Coils 3 times, replace the Battery cables, the battery, and i have done Arron Cakes Grounding on EVERY GROUND in the entire car.

 

ha!ha! sorry to hear, have you checked the flux capacitor, thats usually the problem if not the only other thing is the continum transfunctioner. basic pythag

 

Dude if your not going to help don't comment!

 

U sure bout the ground under the intake? It bolts to the bracket on the driver side. Its a bitch to get to without the intake off. I did intake gaskets on my car and had the SAME problem. I left that bolt loose. The only thing my car did yours doesnt is the shift light would come on when u cut the key off. And maybe its a broken wire. The connection may be good but pin check the ecm connector (with the ecm unplugged) check continuity to ground. Only problem is i dont know off the top of my head what terminals are ground. Also that shorted ground caused the main 80a to blow

 

No spark meaning the car is not turning over when you start it? Check your starter, starter relay, and also all the fuses.

 

@ Recian I made sure that ground was tight. im gonna redo the ground under the Trailing coils. ill check those pins later its getting Dark out. @RX_214 it cranks just fine Battery and starter are new. And all fuses are new and still in tact

 

This helped me out when i had my issue. Maybe it'll have some useful info for ya
