I just installed a 3 inch exhaust, on my 68 Camaro. Went to start it, it started, but died quickly, like I shut it off. I checked fuel lines, and made sure I have power to everything. I'm running a Mallory Unilite and coil. HELP !!!!

Aren't those Unilites notorious for eating modules? That'd be my guess....KZ

what do kinda motor do you have?? 3 inch may be too much pipe and is not giving your car enough back pressure/vaccuum to keep it running. Unless you have a pretty stout engine 3 inch is too much

I've got a 454, and I'm running a mechanical advance, so I don't think vacuum would be a problem.If it is the module, can I do something to protect the new one, or should I junk it, and go MSD...

Did you check for spark? Fuel at the carb? Also, an engine will run with NO exhaust at all so, I seriously doubt no backpressure........Otherwise nothing would run at the Drags

Is the Unilite a fresh install with the exhaust, or have you had it running before the exhaust installation? I've used Unilites for years on many builds, and never had one go bad - the ones I've seen that died went belly-up simply because someone fed them with 12 volts, which fries the module; the instructions are VERY clear that the power MUST be fed through a resistor or a resistance wire.
