General Buick Tech / GN Won't Start
« on: August 23 2017, 10:25:26 AM »
Hello everyone. I am new to IHADAV8 and hoping for some help. I drove the car for a few days in a row and then I went to start it in the morning and not even a kick.
I have no spark and I used a noid light to figure out I have no injector pulse.
I have fuel pressure and can hear the pump running.
I have checked all my fuses (CCCI, ign etc.) even replaced them with known good ones just to be sure.
I have checked the orange wire going from the battery to FAST system and all is good.
I have replaced (and tested) the crank sensor. I have rotated the crank by hand while using a multi meter and have sensor voltage when the ring passes the hull.
I have replaced the ignition module and coil pack with one that I had. I have also borrowed one off of my friends GN which works great on his.
I have checked all the grounds and also used multiple jumpers to add grounds just to be sure.
The only thing is that I don't have is an engine service light. With the classic FAST system will you have that on? I don't ever remember seeing it on. When my cam sensor failed I noticed I didn't have the service engine light on. Once I changed the cam sensor I don't remember if the light came on or not?
Anything I am missing?
Thoughts...
Thanks!!!!
