Sounds like you need to change the pump. If battery power doesn't make it work, it must have burned out. How old is the pump? It must be pretty old to still have a carburetor. Even throttle body injection that looks like a carburetor would make it pretty old?

SOURCE: on my 1994 plymouth voyager the 3 wire harness to fuel pump (blue wire) doesn't have 12 volts; should it? fuel pump quit then worked once when hot-wired with 12 volts. fuse and relay is good.

The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.

SOURCE: 2000 grand am. replaced relay,

Pull the relay and make sure you have 12 volts there. Pin # 30 is the power to the pump. this will tell you which way you have to go to find a short or corrosion in the wires. let me know

Fuel pump not working, will not prime, cranks but no start unless putting fuel in intake


Check voltage and ground at fuel pump, pink wire is voltage black wire is ground. The initial prime is only for key on engine off, lasts a couple seconds. You use a testlite to check voltage and ground.
Check voltage and ground for fuel pump relay. Also, you have an inertia switch, you have to check that.

For testing, you can use jumper wire at load side of fuel pump relay, the load side is that line with the arrowhead. When relay is energized that line moves to the other terminal and sends voltage to fuel pump, just unplug the relay, use jumper between terminal 30 and 87, terminal 30 is hot all the time.
The voltage and ground for the control side of relay is controlled by computer I believe, If the control side is the problem, I'd have to check wiring circuit and computer.
With engine cranking, you have injector pulse, also?

No fuel. pulled off fuel line to carb and cranked engine no fuel coming out. Relay under dash working. No sound at fuel tank when key is turned on. Are there any other fuses or relay for fuel system?


Check for power output at the relay, there should be a pink wire with a black stripe that connects to the fuel pump relay, when the key is turned on it should have 12 volts for a few seconds, then drop to 0 volts. This is the prime function that builds fuel pressure before you start the engine. Even though it clicks it doesn't mean it works - the contacts could be bad. This wire continues straight back to the pump, if it has power there may be a damaged wire between the relay and the pump or a bad pump - the pump is fairly common on these vehicles.

These pumps last longer if you don't run less than 1/4 tank of fuel - keeps them cooler.

No power to the fuel pump.


Sounds like a shorted motor.

30amp auto shutdown fuse blows is it alternater


The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements. The Fuel Pump Relay is a separate relay controlled by the ASD relay input to the PCM. Fuse #12 (10amp) provides 12 volts to the coil side of both the relays and the ignition switch. Fuse #6 (30 amps) supplies 12 volts to the output side of the relay. Fuse #16 (15 amp) from the relay output to the Oxygen Sensors and Fuse #26 (15 amp) relay output to the PCM. Fuse #24 (20 amp) is Fuel pump relay output to fuel pump. Fuse #19 (10 amp) supplies 12 volts direct to the PCM.
look for burned or melted wires in the offending circuit.
sounds like you wiggled a wire while installing new relay.

No voltage to electric fuel pump relay?


voltage comes from fuse box, should have a fuel pump fuse, check for blown fuse, if not try jumping a fused wire from 12 volts to relay and see if fuel pump runs, hope this helps ?

2000 chevy silverado 1500 4.8 4wd will not start


Your pump is controlled by the pcm using a 12 volt signal to the relay. Pull out the relay and probe the relay socket with a voltmeter. There should be 2 terminals with 12 volts when the key is on. With the key off, there should be one 12 volt terminal coming from the ecm b fuse. See top left of diagram below.

Dodge 1500 1995 pickup 7.5 volts to fuel pumpwill not start applied 12 volts pump runs book sayes pcm de-energize booth relayes and will not send proper voltage to fuel pump


There is a red and white wire feeding the fuel pump relay from a 30 amp fuse. Both the shutdown relay and the fuel pump relay are grounded by the PCM, so if the fuel pump relay is grounded it should be "on" and providing a direct link from the pump to that fuse.
You should have battery voltage on that 30 amp wire before the relay and then on the dark green and black wire going to the pump.
If you don't have battery voltage coming from the 30 amp fuse, the problem could be before the fuse.
That 30 amp fuse is hot all the time, so it is powered by a fuseable link coming off the battery.

99 chevy s10 replaced fuel pump but the new one is not getting power i ran a hot wire to the pump and it comes on in the tank so i know the pump works.i replaced the relay under the hood that said fuel...


It sounds like you are on the right track. Here are the basics for your pump. I took a guess at the engine size and went with a 4.3 V6, Hopefully that is it.

1. There is an ECM B fuse, 20amp that feeds one side of the relay.
2. You have already mentioned the relay. The other side of the relay feeds from the VCM or Vehicle control module.

Remove your relay and check pin #3.. You should have 12volts with key on. If not check the ECM B fuse.
If you cross pin#3 and #5 on at the relay location you should feed 12 volts to your pump and it should run. If it does not, look for a ground problem on the black pump wire or a broken wire between the relay and the pump. I show a gray power wire to the pump.

Hope this helps.. Best of Luck..

I am not getting a signal to my fuel pump, fuel pump relay nor the 10 amp fuel pump relay fuse. I have checked my wiring from the ECM to the FPR and it is good. Where does the power come from through the...


The fuel pump relay is powered by a fusible link connected to the starter solenoid on the positive battery terminal. That fusible link feeds the 10 amp fuse near the relay. You can test the fusible links with a 12 volt test lamp. If the fusible link test okay check for an open circuit in the wire between the link and the 10 amp fuse. Hope this gets you fixed.
