I have a 305 tpi engine out of a 87 firebird. Stalled on me after a long ride and had no spark. Changed out coil still no spark then changed ignition module and started right up. Took it out for test ride and stalled again after about 30 minutes and had no spark. Been sitting a couple weeks now and started right up today. I don't trust going to far as this might happen again.I am looking for some help to what is going on thanks.

 

Try a rotor.

 

I had this problem on a previous car I owned. It turned out to be a faulty MSD box. I removed it and all was good.

Like mentioned above, try replacing the rotor and if that doesnt help then look at the module again in the distributor. use a quality part and make sure you use the thermal paste.

 

There is also a test or 2 you can do on the pickup coil to make sure its ok.

 

Ok I thanks I did use a good module and thermal paste. I will check out the rotor and looking at changing the magnetic pickup and checking and cleaning grounds thank..........
