No Spark

I have a friend with a 1985 Camaro 2.8 V6 with HFI electronic ignition with a remote coil.
He replaced the ignition module because I had no spark. It ran for two days and now he has no spark again.
Does anyone know what types of things to check for. I have no electrical schematic or trouble shooting guide.
Hopefully someone might have some suggestions on what to check for.

On my 2.8 Blazer, I have found that the wires on the coil (primary and secondary) seem to work loose every once in a while.

The crankshaft sensor could be giving you some trouble.
First check to see if you are getting 12 volts to the ignition coil, it will be the red wire. If you have 12 volts applied then check to see if the crankshaft sensor is giving you a reference, if the crankshaft sensor is not giving you a reference than you need to replace the cs sensor. The crankshaft sensor feeds a signal to the computer and to the ign module, if you are getting no signal from the crank sensor than you will get no spark. U have to find out if you are getting power to the ignition module first before you try this
Use the proper tool for the job!!!!
