How many amps should a electric fuel pump draw?
How many amps should a electric fuel pump draw?
On most vehicles, a new fuel pump draws about three to five amperes of current. This amperage or current draw can be measured at the fuel pump fuse located in the vehicle’s fuse box.
Why does my Chevy fuel pump keep failing?
The Chevrolet service bulletin states that the cause of the repeat failures is due to worn or damaged electrical connectors at the fuel pump assembly. When you get the Delco replacement parts it comes with a new connector on the fuel pump side.
Where is the connector on a Chevy fuel pump?
When you get the Delco replacement parts it comes with a new connector on the fuel pump side. The problem is the connector on the vehicle side of the harness. In the online Chevrolet repair manual I use, a Tech Tip states, the connector should be replaced with the fuel pump assembly.
When did the Chevy fuel pump come out?
It started on Chevrolet truck models from 1996 to 2003 model years, but has expanded to other models as the connector and pump assemblies are not aging well. In fact, I have a financially strapped friend with an 04 Silverado that now caries a heavy rubber mallet in the truck.
Is there an electric fuel pump in a GMC pickup?

How can you tell if your Chevy Silverado fuel pump is going out?
The only way that you are going to know that your Silverado’s fuel pump is going out is that it is no longer providing enough fuel pressure to keep the engine running under a heavy load, or at high-speed.

What causes a fuel pump to go bad?
4. Damaged Fuel Pump. If you notice damage to your fuel pump, it may be caused by a restricted fuel filter. The clogged fuel filter puts too much pressure on the fuel pump and prevents the proper amount of fuel in the fuel tank from reaching the engine.
How many amps does a PFI fuel pump draw?
High-pressure pumps, like those in port fuel injection (PFI) systems (35 to 45 psi), require more current than low-pressure pumps in throttle body injection (TBI) applications (9 to 13 psi). A TBI pump may have a normal current draw as low as 3 to 5 amps, with PFI pumps pulling 4 to 6 amps on average.
Where can I find a damaged fuel filter?
Damaged Fuel Pump Fuel filters are a common service component found on virtually all vehicles equipped with internal combustion engines.
