It sounds like you may have a bad fuel pressure regulator. The fuel pressure regulator is in the throttle body housing and the throttle body in your truck works best at 13psi to 15psi, Any other setting will cause problems. Check the vacuum hose to the fuel pressure regulator at the throttle body and check the fuel pressure at the shredder valve. The way the throttle body works is for the first 75% of the throttle, the ecm uses the signal form the O2 sensors to control the air fuel ratio and tries to keep it to 14.7:1 but at full throttle it by pass the O2 sensor signal and runs the engine richer and advances the timing so you can drive with wings like red bull. The Map sensor then takes over to promote the engine to run richer so you don't run lean and detonation occurs. If there is a problem with your throttle body position sensor, map sensor. and fuel pressure regulator, then at WOT (skinny peddle down) you may be running to rich. The other thing to is if your fuel pressure drops at WOT you'll get a lean condition and then you'll have detonation ( Knocking) and the timing will be turned down to keep detonation from occurring again and that may be the cause if your check engine light too. First and easiest thing to do is change the fuel filter and add fuel injector cleaner to you gas tank, buy a throttle body cleaner and clean your throttle body to make sure you don't have varnish build up around the throttle body, just follow the instruction on the can. Throttle body cleaner not carb cleaner. Start with that and i hope we don't have to do any more to get your truck running like a rocket. Good luck and keep me posted. Be glad to help.

after installing distributor a camshaft offset check must be performed.this requires a scan tool.start engine with scan tool attached to diagnostic connector under dash,go to cam offset,it should show a value of 0 to -2 or +2.to adjust cam offset shut off engine,loosen dist. hold-down bolt,which should be 13mm bolt head.move dist slightly,start engine and rev to 1200 rpm and check scan tool to see updated cam offset value

Are you getting spark at the plugs?

SOURCE: My security light is on and my my 1997 chevy lumina won't start

I had a similar problem in my '97 Cutlass Supreme. The two vehicles have the same electrical makeup. My car would not start either and I had to take it to the dealer. $544 later, it ran fine. My problem was a shorted out ignition. You may have shorted yours out when you arched the starter. The only thing you can do is to disconnect the negative battery terminal and let the car sit for about an hour. The security light may go off then. I hope it does. If not, then to the dealer it is.
