The car fuel pump has no electrical current to it

the relay is only a current buffering device, ( a poor mans transistor i call it)
if the pump or it's wires are shorted, the relay can melt.
the first test is pump voltage
if the volts is like 6v (low) cranking we pump check current.
5 amps is typical for these small cars.
15 amps is bad.
if confused get a automotive electrics/electronics tech to fix it.
He has a nice meter to find this fast.
here is one.

the best tool is the AMP CLAMP (DC amperes)
i put it on the line and check pump current.
the pump is fuel cooled and fuel lubricated,never run the tank dry.
nor run the car (pump) with filter clogged, it overloads the pump.

check your fuses or the switch in the trunk on the right side on the passenger side on the panel you will have to move the carpet to get to it.

What's the fuel pressure ? Hook up a fuel pressure gauge an test it yourself . fuel regulator ??? It's a fuel pressure regulator . I was starting rough and I had a diagnostic done. "They" said it was the fuel regulator.
Hard starting - not starting rough . What year is the truck , what engine does it have . If they don't know for sure what's wrong you better try another repair shop that know's how to diagnose .
Electrical problems can lead one to believe the fuel pump is bad . Doing voltage drop testing on the electrical circuit is a very good test.

Plus doing current testing can pin point a bad fuel pump .

u check the fuel pump relay there should be another relay u can switch in the fusebox for a quick check

Relays work buy using a small electrical current, to close the contacts for a larger current.
So the wires that control turning the fuel pump on are a lot smaller than the wires and current that the pump actually uses.

It's possible. You will have to test the pump(at the fuel tank electrical connection) to see if it's getting current when the ignition is turned on. If it's getting current, the pump is most likely bad.

most common is the fuel pump kill relay under dash on left side I believe. I think its under the coin tray. This was a common fail item. local honda dealer or possibly parts store will have it.

Then you have a ground problem. that is the only thing that will keep current from traveling through the pump is that it is not grounded.

with the key on there should be power (12 volts) to 2 terminals, you need to cycle the key to sense the power, it only stays on 5 seconds, have someone turn the key on and off while u check..

two things one there should be a fuel pump fuse under the cover on the right firewall check that,two there is a ground on the frame left rear by the tail light harness it will shut down the fuel pump
