Guys I need some help here. I got a 95 mustang with no spark... I've tested and replaced a few components. Let me start from the beginning. Its a 95 mustang it originally was a v6 automatic car has been swapped to a v8. The harness was bought from a 95. The engine harness, mass air harness, and computer are all from the same car. The tfi module and distributor were from another car but have been tested and I even tried new replacements.I've done all the no start no spark tests and I'm not getting the signal to fire the coil. If I ground out the side of the coil I can make it fire. Also the injectors are not pulsing and the fuel pump does not prime. The rest of the sensors show the reference voltage. The injectors show the bat voltage on the one side and the other side shows 8.3 volts?? I don't understand that. I've tested that the ignition module, coil, and distributor they all have voltage. Now the weird thing when I hook up the scan tool it will not communicate but when I turn the ignition on the scan tool completely shuts off (it is hooked directly to the battery) It seems like something is shorting out. The injectors do not preprime either. The transmission harness is not in the car. I have the neutral safety switch bypassed. The processor is a t4mo. I'm almost certain I have had one of these year cars run with out the trans harness. I've done it a few times in newer ones for sure. I've tested at the spout connector and it does not flash when cranked. I've probed, poked, prodded and prayed and so far nothing. All grounds have been gone over. There is a 4 gauge block to ground. Please Please some one help me. The engine is in this car is a turbocharged, 342 cu in stroker 302. I'm so close to having a running turbo car for the first time in almost 10 years I can barely take it!
