hello, I am new to the forum and idk if this is where I post a thread like this but here it is anyways 😅 my car chassis is a revup and I recently swapped out my revup for a reg de engine that also has a greddy ttk... I swapped out my revup ecu for a de ecu as well but kept my revup harness. this de ecu came from a tuner who already has nats deleted. anyways, the car cranks, she spits fuel, but no spark... I checked for 12v at the the two cam sensors, the crank sensor, the coil packs, and maf sensor for giggles. they all are receiving 12v. I'm kinda at a loss right now. anyone come across this issue and get it resolved? TIA

 

Have you actually pulled the plugs out, put it back into the coil pack, held the ground strap 1/4" away from the aluminum plenum, and actually visually checked that there is no spark?

If you're getting fuel you should be getting spark as well, the two are both part of the same system and it either works or it doesn't. If you're getting one but not the other I'd suspect a wiring issue.
