I've replaced fuel pump, fuel filter, and ignition module.The motor is still lurching and stalling upon stopping some times and running rough at times also. Also now it emits white smoke when starting or reving motor. I can hear the fuel pump working when I turn key so why is it still having a problem. Your feedback would be greatly appreciated..

Happens all the time with 70's 80's and 90's GMC trucks. Replace the control module in the distributor cap.

even though parts are new they also come with defects so it sounds as if when you turn the key you hear it working and other times not at all hmmm connections are tight ? could be faulty fuel pump or relay .

maybe your iac valve is not working? it takes place of a choke or temp sender to computer could be bad which controls t I.A.C. known as the idle control valve,do you have any codes?

when you shut the truck off is/was there a swishing/bubbling noise coming from the tank?
Theres an orange rubber in the fuel tank that connects the fuel pump to the sender lines. if that rubber is torn you may get it to run but not stay running for more than a short period of time.
Thanks. Keep updated for any more query. You can rate this
