We found the problem by taking the truck to the dealership, after spending $550.00 on parts and having everything we could remove tested or we purchased them new and replaced them. We spent two weeks on it and took it to Chevrolet but it took them three days after all we had done, the problem turned out to be the gear on the distributor, sure we replaced every part in it but because we could not get the distributor out with the intake on it we had not even considered the gear, thanks for your assistance and maybe we'll try you again next time....Thanks again.

A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech

Time for a complete tune up, this time put a distributor cap on too, plugs wires cap rotor, and use quality parts. what you got here is condensation getting under dist. cap most likely because cap has a hairline crack in it.

I had a simular problem. I had bad plug/coil wires. The foil insulation from the engine cover would draw the voltage from the wires.
