TPI problem answered... I\'m dumb I have been having a lot of problems with trying to get my TPI system to fire the injectors and I couldn't figure out why. I went threw all the tests and they all didn't find anything to solve my problems. So I went back threw all the wiring and I found my problem and I feel REALLY dumb. I made a retarded mistake and I am kind of embarrased to admit. I hooked the ECM power wire to a wire that was keyed source, but turns off when the ignition is turned over so every time I tried to start the motor it would cut the power to the ECM. /forums/images/graemlins/crazy.gif I solved that problem. Now I have to adjust the timing a little and it should fire. It almost fired last night but it will fire soon. Please learn from my dumb mistake and think about things like this when you are wiring things in your truck.
