Hey , check your ignition cord from the distributor cap to an ignition box. My blew off and caused the same problem. The connection could be corrorated if not blew off. I had to buy all the spark plug wires to get that exact wire ( only cost 20 dollars for set) but replaced and it fired right up. I also bought spark plugs and tuned it up as well. Thats also easy just remove your front tires and the plugs are right there man. Best 35 dollars I've spent in while.

Aftermarket fuel pump failure? Try "thepartsladi" store on eBay for low price GM OEM parts. Could also be wiring harness to fuel pump.

SOURCE: service engine soon light is
Evaporative emission control system Fuel Tank Pressure (FTP) sensor high input-----
This is a normal defect in late 90's model GMs. To be more specific, your fuel tank has sensors set in place to slowly release pressure to regulate the fuel system. One of the sensors has malfunctioned and is causing the service engine light to turn on. It has absolutely no bearing on the mechanical operation or performance of the vehicle. Unless you want to spend over a thousand dollars to repair something unnecessarily, just learn to live with the light. Nothing else will come of it.

SOURCE: Why does mi 1999 olds
It sounds like either your fuel pressure coming in to the fuel rail and the injectors, or your MAF (Mass Air Flow) Sensor. I would buy a can of brake cleaner and pop your intake hose off of your filter box, and spray a little on the sensor thats in there. May not solve the problem, but it will eliminate your MAF. Also go buy a can of Sea Foam. It is a fuel additive that cleans your system. Pour the whole bottle in your tank and run normally. It may clear up after a few trips. If neither of those work I would look at your fuel pressure regulator, and O2 sensors. Let me know. Thanks.
