Hello, last you heard from me I had blown a u joint.
1991 5.7 Ltr. GM engine.
I replaced the u joints, center socket, gimbal bearing and seal, bellows etc. Put everything back together and engine would not start. It does turn over and am getting gas. I checked for spark at the plug and got nothing.
So I ordered a new coil. I installed the new coil and tried starting and nothing. I checked for spark coming from the coil to the distributor, nothing. Pushed fuse at key. I also pushed circuit breaker at the mercathode. Rotor does turn.
I found this site on the web, which showed me possible problems. http://www.sterndrives.com/no_start_condition.html
Below is a quick list of items which can cause a "no spark" condition from the coil:
1. A bad key switch.
2. A blown ignition fuse.
3. A bad harness connection or bad harness.
4. A bad shift cable.
5. A faulty Shift Interuptor Switch on the shift plate assembly.
6. A shorted tachometer.
7. A removed or faulty Safety Lanyard Switch.
8. A bad ignition coil.
9. Breaker Points worn or not adjusted (conventional ignition).
10. A bad condensor (conventional ignition).
11. A faulty sensor (Thunderbolt or Delco).
12. A bad Ignition Module (actually very rare).
13. A bad timing chain (rotor does not turn).
A few questions from this.
Where is the ignition fuse?
Where is shift interuptor switch?
