I need help. Just got done wiring my sr20det. Every thing works, except that I am getting no sparks and the fuel pump won't come on. Please help.

no spark - check the ignitor with a multimeter to see if that's in working order, if that fails - replace, otherwise move to the cas.

fuel pump, check the fuse yet?

I try it with my firends ignitor it still didn't work. I tested the plug by the ignitor and I'm no voltage at all. For the pump I have check all the fuse and they all seems to be ok.

Thats what I was thinking. cut harness= . Me personally I would contact heavy throttle. I believe their harness repair service is only like $100. I did my first DET swap in a 1.6 sentra quite some time ago. I went through about 5 hacked harnesses. Even tho the car ran it was crappy. When I finally got a good harness in there it started the first time and every time after that. Just food for thought. Hope it helps
