Why won’t my truck start?

Asked by Shane Aug 18, 2020 at 07:42 AM about the 1998 GMC Sierra 1500 C1500 SL Standard Cab SB

Question type: Maintenance & Repair

GMC Sierra died on me 3 wks ago.
First thought I ran out of gas bc gas
hand doesn’t work. Filled up tank, still
won’t start. I’ve change fuel pump,
filter, relay and now computer. Garage
said pump wasn’t getting power.
Computer did help a little. Truck
would start but rough idle, died when
I gave it gas. Any help would be
appreciated.

I took it to mechanic and they decided pump wasn’t getting power. They thought maybe it was computer because of faults that wouldn’t reset. Yesterday I bought and installed new computer. It’ll sorta start but only idle (rough), then if I give it gas it dies.
