1998 chevy s10 new dist cap and rotor fuel pump

could it be your crank sensor?
having a similar problem with a dakota. dodge tells me it may be the dist, but seeing as how you replaced it with a new one it could be that the sensor needs replacing

It sounds to me that your control module is bad It is located on the left side facing the engine on top of the intake

sounds like it could be the modular under dist. cap. i would replace the rotor button and dist.cap.

98 chev pickup s10 put gas in the gas tank drove it about 2days and the check engen light came on had it check mech said it was the gas cap replace the gas cap the light back on now what help

Make sure the injectors are pulsing. Whatch to make sure mists oj fuel are coming out.

The problem is electrical. Check the dist. and timing chain

spider injection is a common problem with these vehicles, is it consuming gas more than usual, is the oil smelling like gas? The spider is located under the upper intake plenem. There is also a fuel pressure regulator connected to the spider assembly that may be faulty.

Check to see if it has spark. It may be having a problem with the distributor. If you have put fuel to it to no avail, then you probably dont have spark. Could be the cap / rotor, the coil, the pickup in the distributor, or power going to the coil or distributor. Check for spark and if you dont have any, make sure you have power to the coil / distributor. If you do then try a new coil cap and rotor. Hardest part would be the pickup in the distributor if thats bad.
Heres a link to an article on the types of distributors and how to rebuild them.
