No spark

[crazjames]

Hi guys. I have a 1996 tahoe and I have no spark. I have replaced crank position sensor, the cam position sensor,ignition module, coil, cap,rotor, wires and plugs. They all were original so I replaced them. I have no check engine light on either. I'm pulling my hair out trying to figure this out. Please help me.

It's a 5.7 and I have no spark at the coil!

Was there spark prior to replacing the parts or were you trying to resolve a no spark problem?

 

[crazjames]

I had intermittent spark before.

Did you replace the pickup coil when you did the module. Check for broken wires inside the dist.

 

[crazjames]

Yes

I would check to see if you have voltage at each of the connections to the coil, and sensors.

As they mentioned above, check all vital connections and grounds. One possibility would be to check your ignition switch. If it's faulty or just worn out it could be the culprit.

I figured it out today. It was a bad connector to the crank position sensor. Replace the connector and it started right up.
