Hi,

I have a 1987 chev K2500 that the fuel pump and filter were replaced,fuel tank cleaned out also.I can here the fuel pump cycle when the ignition is on,but on this vehicle will it be continous ? When you add gas into the throttle body it fires and runs a little then of course quits.After the pump was installed it did run for a few minutes,but always quit on me.It seems to me like a fuel issue,but could it be something else? Ignition or some sensor ? I am not to familiar with this throttle body .Are there any issues with these ? Has the 5.7

Thanks Bob J
