No Spark in SR swap! Help! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok, my friend is having a problem w/ his SR swap. He cranks it and the fuel pump turns on adn the car cranks healthly. The problem is that he is getting no spark to his coil packs. He already tested them and none of them get spark. Would there be another way to see if it is indeed the coil packs are bad? What else could it be ? thanks guys, zilvia always helps me. They should make a cereal, Zilvia puffs. haha

cmon man, im judging u have a SR20DET by ur avatar, so swap your coilpacks into his since yours are working.

if they still dont fire using ur coilpacks, im guessing its the wiring.

ah, good idea.

unlikely all 4 cpaks are bad at once, my guess is ignitor or improperly done under-dash wiring

Test the ignitor first
Then test coilpacks if the ignitor is good
Lastly check your wiring to the ignition system

Just as a precaution, if you're going to start randomly testing parts, take one part at a time from the car with questionable wiring and test it in the good car. I would be very careful about putting a known-good into a bad car. It can damage your known-good.
