87 Chevy
Pick-up, Fuel Pump Problems
Q: I have an ‘87 Chevy pickup that won't
start. It will run on starting fluid briefly. I hear or see no action
from the pump. I held a steel bar from the tank to my ear and had someone
turn the key on with no resulting noise. I have power to the pump relay
but can't get at the pump without removing the tank. It's such a nasty
job. Is there a way to check the pump without removing the tank? Could
it be a sender, a fuse, or the computer? When I parked the truck it was
OK. The next A.M. it wouldn’t start. I really need help on this one....Bob
A: Of
course check the fuse first! If the fuse is good, go to the electrical
connector at the gas tank, there is enough slack in the wiring harness
to unplug the connector to the fuel pump to check for electrical power.
Test for power being supplied when the ignition key is first turned on
and while cranking the engine over. If electrical power is available yet
not a sound from the fuel pump, you likely need a new fuel pump. You’ll
have to remove the gas tank to replace the fuel pump on your vehicle and
be sure to replace the fuel filter as well to perform a complete service.
