First off, I'd like to say that this site has an incredible amount of knowledge on it. So kudos to everyone that made that possible.

Alright, when I turn my key to run I have no dash lights and it acts as though my battery is not even connected (which obviously it is). When I try to use(while the key is in the ON position) my signals and my wipers aren't working either.

Here is what I've Replaced/Checked so far..
-Ignition Switch
-Main Relay (driver-side kick panel)
-Blown IG fuse in the under-dash-fuse box.
-Replaced all blown fuses
-Swapped out the PT6-A50 ECU. (apparently this particular one is hard to find)
I'm not sure if this matter, but I could only find a PT6-A51 ECU out of a 91 accord EX.. :-/
-The wiring harness that goes from the ECU to the main fuse block looks good and has no noticeable burns or "fried marks"
-Ive checked about roughly 90% of all connections for continuity.

I've come to a dead end. If anyone knows what the hell I'm overlooking, or if you've encountered this ridiculous problem, please reply..

-Thank You

 

Grounds? Have you checked the grounds? The one at the valve cover, the trans, and the frame. Maybe.

 

I would say it's a grounding problem also.

I once had this problem with a crx, turned out the main ground wire right from the battery was all full of the white powdery junk, making for a bad connection

 

the problem wasnt your old ecu most likely. check all your grounds. and check your battery. i know alot of guys who put batteries in that are either too big or they dont secure them. when they hit a bump or show off in the parking lot doing burn-outs the battery jumps into the hood and shorts all kinds of **** out. even starts fires sometimes and burns MAP sensors. is that youre problem? the battery too big or unsecured?

 

I have the same problem i think.

I keep blowing the ECU fuse and i have no idea where it could be comnig from. I am blowing thru 15 amp fuses now..hmm

 

I did't know big battery would cause problem.. I thought i did check to see if good..

 

Have u Checked The After Market Car Alarm ?? Fuses and Connectors
