Need help testing fuel pump


not reason why stated???????? fun, ?
the fuel pressure is over 60 psi, try not to get a bath in fuel.
right? there is no reason to this. (unless tank contam)
you can hot wire a pump with rear connectors pulled first
then measure rail pressures., (over 6 test there)

rule 1 , pump is fuel lubricated
rule 2 pump is fuel cooled.
do not violate 1 or 2, or you will burn it up., i promise!

Fuel pump wiring for aftermarket GM fuel pumps


When replacing fuel pumps in chevy or gmc trucks and suv's the aftermarket fuel pumps come with new plug and wire connectors. Which requires you to cut off the old pigtail and connect the new pigtail to the vehicles wiring, the reason the manufacturers of the new fuel pumps did this is to fix problems with the old style connector that was on the factory unit.

I have a 1996 gmc savana 2500 and ive put 3 fuel pumps on since i had itbut this time i put new pump in its not gettin power...the relay is new and the new pigtail but nothing please help asap thanx


One of the most common causes of fuel pump burnout is a clogged fuel filter. If that's not the problem have the fuel regulator checked, if its not releasing some pressure the pump is trying to run at a very high pressure and will fatigue the motor quickly. Also if you drive around a lot with 1/4 tank or less your pump is not cooling well due to not being surrounded by fuel.

I replaced the fuel pump on my 2004 1500 5.7 liter. Started at first but only ran at idle for a few seconds and died. Now i have no fuel pressure at all. Also the wiring connection at top of fuel pump


gotta start with the color code of the wiring. verify that is correct first. you have to have fuel pressure for it to run obviously so make sure you wired it correctly. Here is the color code according to Mitchell OnDemand
black/orange= ground for fuel pump
orange/red=power on for fuel pump(only gets triggered from fuel pump relay)
dark blue/white= signal to pcm for fuel level
dark blue/ dark green= ref voltage

If that is ok then check for relay activation. Fuse 17 is the power source for that relay. If you have a good fuse but no relay activation you could throw a relay at it but if that doesnt do it then its gotta go to a shop. But if you are curious....
Relay code
pin 30= hot at all times
pin 86= relay control trigger from the pcm
pin 85= hot in run or start
pin 87= power source to fuel pump.(i.e. orange/red wire)

the relay will have numbers on it designating the correct pins. Get that right first then move on to the next. I'll be here. Good luck!

Replaced fuel tank and pump and now car won't start.


no engine stated.
details are based on that..
so is it still the old pump there,
this is very simple
using a volt meter. (the pump has 2 wires, measure across those)
back probe that connector to the pump. 2 pins.

12vdc cranked, if you have 12vdc cranked
but fuel pressure is 0 the pump is gone
no pump runs on 0v, or 6v, its 12vdc there,
i can not understand those fues tests
if the voltage fails to the pump it can be
the power wire or ground wire failing .
do all tests connected, or the readings will be useless.
connected is live testing, under full real conditions
and win. every time.
if ground is tested and rises to 12vdc cranked, ground is bad.
only Ohms laws here,a simple equation.

not sure why your float fails. my guess its bad.
and easy test using ohms, disconnected.
that is another problem.

ill look at your fuse, pretend V6 engine.

the service manual shows
f10 fuse is fuel pump
12vdc both side cranking is a GOOD FUSE.
note all words above.
F10 gets all power from pump relay,
so if you dont crank the relay can be off line
an F10 will be dead.
(the schematic is clear)

here is a facts on all cars, next (pure software in PCM )
  1. pump only runs 3 seconds key on, ,
  2. pump never runs, if not cranked.
  3. run cranked and all run if engine stays running.

see? and varies by year, engine, and even ECU upgrades
so a SAVVY mech always cranks to do tests.
that means its a 2 man job. sorry but that is a reality of working any car until you learn what yours does.
warning have a care here that changes rule 1 to 2, below 20F out door temps, (fun no?)

recap
crank and measure like this.
the pump has 2 wires, red hot, black ground
meter across, pins 1 to2, red back is 12vdc cranked
meter black tests lead (volts) to body perfect metal ground
and meter red lead to pin1 red shows, 12vdc cranked
12vdc means 10 to 12vdc cranked, (battery does that)
then move red test lead to pin 2, black
cranked, 0v, if see 1 volt or ore the ground called.B26 is bad.
if the pump has 12vdc on it, you hear it,
do not run it dry its fuel cooled and fuel lubricated or you wreck it.
if it is heard to run you then see fuel spec fuel pressures.
or its bad. (30psi?)

Need color code on new connector


Just did my fuel pump on the 2001 isuzu rodeo. Well here is what you need to do about the different wire colors. First disconnect your negative battery. Drop the fuel tank and replace pump. Remember to have a splice kit in hand. Ok now here is how you connect the different colored wires. Black goes with black. Gray goes with black and orange wire. Purple goes wit blue and yellow. And the last wires goes together. I hope this helps.

2001 ford taurus will not start. When cranking or turning the key I do not hear the fuel pump prime kick on. I have checked the red button in the trunk and it was not popped, I also swapped out the fuel...


OK, let me help you with the diagnosis without having to do the "Fred Flintstone beat on the fuel tank" thing.

All you really need is a 12 volt test light and a LONG jumper wire.

Since you already know where the inertia switch is (red button in the trunk), this should be very simple for you.Connect one end of the jumper wire SECURELY to the NEGATIVE battery post. Then string the wire back to the trunk (we want to make absolutely certain that we have a known-good ground for our test lamp).
Then connect the cable end of the test lamp to the wire.
Disconnect the connector at the inertia switch. Using the probe end of the test lamp, probe Pin #1 PINK/BLACK (unfortunately, on your vehicle, BOTH wires are PINK/BLACK, so you know which pin to probe, pin #3 is the one that is not used - pin 31 is the one on the other end of the connector.)
Turn the ignition switch to the ON position. Your test lamp should light up for approximately 2 - 3 seconds then go back out. If it does, then you powertrain control relay, your fuel pump relay, the fuses for each of them and the PCM are functioning properly. If it does not light, let me know and we will go on to find out WHY.

If all of this is working, you most likely need a fuel pump. It IS possible that you could have a bad connection between the inertia switch and the fuel pump unit, but it is not very likely and you will have to pull the fuel tank to find out ....So, you may as well put a new fuel pump in if you are going to have to go through all of this anyway.

Fuel pump most likely the problem. check both relays EFI AND CIR OPN tested both by adding power to the pickup coil and with a meter accross the normally open contacts they all worked fine, I also...


if the car doesn't start then the camshaft error can be a probable cause. but to check power to the fuel pump just probe the wires with a test light one at a time. the one that powers the fuel pump will turn the light on for 2 seconds and then go out . the computer does this until it sees a cranking signal then turns the pump on to allow the car to run.
