Hi,

I have a 1987 (built 3-87) chev K2500 350 engine.Replaced the fuel pump and flilter,cleaned out the tank.Ran initially for a few minutes,then will only run if fuel is dumped in the throttle body.Will the fuel pump on this vehicle cycle for a longer time then current models ? (it seems like it runs a lot).Is it an issue with the throttle body or ignition ? Thanks for the input.

My 93 sub did this when the ignition module in the distributor was bad. Would run as long as I poured gas in the throttle body but the module wouldn't fire the injectors

Thanks I was told to replace this and will do this weekend and let you know.
