I just put together my new motor and there is no spark in cylinder #1 i haven't checked the other cylinders but the car wont start so im assuming there is no spark in the rest of the cylinders. Is it my coil pack? Any suggestions?
I agree, double check how the crank sensor is set. It can look perfect but be in the wrong position. This happened to me a few weeks ago when mine broke. Swapped a new one in and it didn't fire. After swapping over a buddies coil pack to rule that out, we realized it was one slot off. Worth a check!
The first and easiest thing to do is check and see if you have a "Service Engine" light on the dash when the ignition is on, and then check the wiring harness connectors and fuses.
