Punctuation and grammar go a long way toward clearly communicating your needs... people (including me) are more likely to stop and read your post if it's a quick, easy and concise read than just skip it (like I have the past couple times I've checked in today).



Have you tested for power at the ECU? Leads B+, B1+ and BATT should all have 12v with the ignition in the on position. Check the grounds on both sides of the head; one set connects on the exhaust side near the throttle linkage assembly and the other group connect to the lower intake plenum near the starter.
