SOURCE: starts then quits
Try the ignition control module located under the distributor cap $30 - $60. This is one of two parts on this truck that will cause it to not run or shut down after running for only a short time. The other is the fuel pump I think it is safe to rule that out as your problem

I can't speak for the electronics in your Chevy Sub. however I had experienced this same problem on my Montero and on my son's Dodge Stealth (it too is a Mitsubishi) in both cases I had spark but no injector pulse. In the end both ended up being the engine ECU units, once changed they ran and are running fine. Any chance you know someone with the same truck? If so confirm the part number and swap in their ECU unit. If your car then runs you know the answer. Good luck!

try bypassing the oil pressure switch on the back of the block behind the distributor, if there oil pressure switch goes bad it will do this. had one that drove me nuts trying to fix it then figured out I had to buy a book and low and behold thee it was 3 wire oil pressure switch you can't see between the engine and fire wall just behind the distributor and costs 8 bucks to buy new.
