Greetings guys I have a major problem!! I bought a doner running, working 1995 wrecked Mustang GT and a 1996 V6 mustang planning a complete swap the whole 95 to the 96. I removed the motor tranny the whole nine yards. I swapped the whole dash board together with the harness. The ECM and ECM harness was also replaced together with the injector harness and tranny harness. The engine was rebuilt to a 347 stroker with 505hp at the fly wheel. Now for the problem: With the swap I have no injector pulse and the fuel pump is not turning on with the key forward. The engine turns over but no Injector pulse. I figured it was a ground, rechecked all connections on the harness but turned out ok. Replaced the ECM computer and the CCM with new ones but same problem no pulse and no fule pump turning on. Last night we changed the relay box harness because it was stock V6 but turned out worse now, the CCM is making a loud buzzing sound and engine wont turn over with key. WTF I have been working on this project for 2 months with no luck. There is electrical pulse coming out fron the MSD distributor and the MSD ignition coil running to the spark plugs therefore excluding the fact that it would be the TPI or TFI sensor. The fuel pump works with a just putting a direct 12v plug to it's wire excluding the probability it could be a faulty pump. I tried to tweeck the T4MO ECM computer with the tweecker, changed the injector slopes high and low from 19-26 to 42-51 with no luck same thing. The pulse from the distributor runs all the way to the ECM but comes out just as a constant weak power no pulse. We need a constant positive and negative for a pulse but noid light on injector harness is real weak. This is a 96 V6 and did not come out with a chip on the key so can't be a thing with the alarm either Don't know what else to try or do guys Any help would be eternally appreciated guys. :SNSign: has always answered my questions just by reading but not this time thanks in advance guys ..........
