Hello, I'm a little stumped. My car wont kick even if I spray starter fluid into the intake manifold through the throdle body flap. If I pull the wire to the distributor, and hold it near engine head, it jumps a spark. It does the same thing from the spark plug wire. However, If I hook up the timing light from the positive lead on either the coil or direct to battery and the negative side to ground, the light never shows a spark. I thought that my relatively new timing light may be broken, so hooked it up to a chevy cavalier and it worked fine. I did hook up the sensor to cylinder number 4 which is the correct one for this car.
The issue with car appears to be spark related but cant figure out why it would spark but not send a signal to the timing light. Any ideas? Am I doing something wrong?
Car seems to spark but no signal to timing light. Wont start

Could be spark is too weak?

Was the engine previously running and died, or is this a rebuild? Also, have you pulled and inspected your spark plugs to see if they are fouled?

Turns out I had a short in my wiring harness to the FI system. I had so much gas going into cylinder 2 that it would not fire. Got a salvage harness and it runs good. I will be posting this to a few of my postings as a few items were caused by this.
