As most of you know i put a 4g63T engine in my truck. Well i got everything wired up. and and turned it over, has fuel... but no spark. I checked the plug on the valve cover. nothing. I drove the laser into the garage so i know everything on the motor is good.
Things i have done. Checked all plugs. CAS, Igniter, coil, tps sensor. injectors, coolant sensors Checked for power at the coil and there is power there. Checked grounds and added more just to see if it might be the grounds. still nothing What else should i check for? Im lost as to what it could be. So any help would be greatly appreciated. -------------------- WWW.DRAGSOURCE.NET

Try swapping the ECU into a known running DSM. With all the things you already checked listed above, it's likely the ECU took a random crap (as they like to do) while you were swapping parts.
An easy test would be to swap the ECU into a known running DSM and try it. Other than that I'm without suggestions. You've checked everything else. -------------------- "I hear he tunes the space shuttle also...and that thing is fast"

ECU could be the culprit or it could be the power transistor. Little black box that has either a 6 or 8 pin (depending on year) straight across plug. I had to replace that once to get spark back.
