I know a T-10 Chevy pick upis 4-wheel drive and S-10 is a 2 wheel drive, what is a R-10 pick up?
Modules can go bad from old. worn plugs or wires, how old are yours?
Autozone modules and economy modules are also known for not lasting.
It could be that the modual is overheating due to engine compartment temp around that area. Double check replacement instructions and make sure you use dielectric grease between the mod. and mount area
My 94 C1500 has been doing the same. I replaced the module with one from Autozone along with the coil. The module went bad again four months later (7000 miles) and had it replaced by a mechanic. He said it went bad again because I didn't change the coil cable. Now just two months later, it has gone bad again (I think). I have had the plugs and plug wires replaced and it starts now and then. I'm going to replace the module with a better quality one but would also like to replace the two conductor wiring assembly that connects the module to the coil. It starts when I fool with the connector near the ignition module connector. Does anyone know where to find this wiring harness?
alot of time if you have bad grounds it will not be getting enough volts to the module and cause them to over heat and some times burn them up!
A bad pick up coil can cause an excessive load on the ignition module. I had this problem with my '85 K5. I replaced about 5 modules in 2 months. Then I dropped a new distributor in it and didn't have any more problems.
