Question about 1997 Chevrolet Tahoe

1 Answer

Fuel pump harness? Are you serious?

My car will not start without a jump. I am told it is a fuel pump harness, but this does not make any sense to me. Everything turns over and acts like it will be fine - but nothing. If I get a jump, it fires up after a few seconds of charging. New battery and starter are installed.

    I forgot to add that once it is running, it runs fine. No shudder, no shut off, nothing... Just like it came off the factory floor.

Without a voltmeter and a wiring diagram, you're in a bit of a fix. But I would be wondering why the ignition switch isn't sending power to the coil primary positive terminal, and why it isn't causing the fuel pump to be turned on, too.
Is your check engine light on with key on? The computer should sense ignition is on and briefly turn on the fuel pump through the fuel pump relay, on just long enough to pressurize the fuel line to the injector. But no fuel or fire-you'd better start by checking if the ignition switch has power in and power out, and work your way to the coil.

Where is the ground or grounds on the harness that


I doubt you have a fuel issue if you replaced the pump. Try this to bypass the fuel pump. Spray some quick start or brakle cleaner into the throttle body. If the car still does not start then the problem is ignition related, NOT fuel related. If it does start then go to mitcell1diy online , search. You can get all the diagnoses info there.

No power going to the fuel pump?


the crank sensor is most likely the problem. If the PCM does not sense the engine is cranking then the fuel pump will not turn on. Also just because a fuel pump will run does not mean it will pump fuel.. Jump it while its in the fuel tank to see if it will pump. But still when you turn the key on you only have power to the fuel pump for 3 seconds unless you continue to crank. . If you have a 3 second voltage pulse when you cycle the key on, then spray some quick start or brake cleaner. If it now starts and you know the fuel pump has power then the fuel pump needs replacement. If you don't have the 3 second pulse look at the crank sensor as being the problem,

Put new fuel pump now the pump runs but the power wire only has 7 volts of power how much is it suppose to have


If your pump is running on 7vdc, you are not getting enough fuel pressure to sufficiently supply the engine with gas, and it will run rough, sputter, surge, backfire, all manner of unpleasant things. If this is the case, and you are reading 7vdc while the pump is connected, this could indicate a problem within the fuel pump or fuel pump electrical circuit. Turn the car off, unplug the fuel pump wire harness from the fuel pump, insert your voltmeter leads into the vehicle-to-fuel pump wire harness connector, then have a helper turn the key to "on." You will have two-three seconds before the computer senses no fuel pump return signal, and shuts off voltage to the fuel pump. Observe the voltage coming from the vehicle wire harness to the fuel pump connector, it should be 11-13vdc. If it is, and only drops to 7vdc when connected, there is a partial short in the wiring from the point the fuel pump plugs into the harness, or the pump just creates a large voltage drop. Every device causes a voltage drop while in use, but 5vdc is too much of a loss. Re-examine the fuel pump installation, and make sure there are no obstructions over the fuel pump inlet, and that the wire harness inside the tank is okay.

98 s10 the fuel pump doesnt come on chaned it still dont work changed the relay too


The fuel pump relay is activated by the ECM, Check the fuel pump fuse and both ECM fuse on the fuse panel on the side of the dash. The ignition energizes the ECM which energizes the Fuel Pump relay which powers the fuel pump. Check the power for the fuel pump at the frame rails by the fuel tank. It's common for that area to get corroded and the wires break easy when the fuel pump has been replaced. That short section of wire harness is only $12.00 if need to be changed. If you have a few friends, you can remove the box from the frame since it's only being held by 6 blots so you don't have to drop the gas tank. The other thing you can try to do is to run a hot wire to the pump wire harness after you disconnect it so you don't loop the electrical and see if the pump works. Good luck and keep me posted.

Mazda truck will crank but won't start up. tried jumping it but it didn't work


sounds like you have a fuel pump issue. first check the fuel pump relay. it's in the junction box under the hood. replace the fuel pump relay with the a/c clutch relay or heater relay and try starting the vehicle if the vehicle starts it was the relay if it doesn't check to see if there is power going to the fuel pump if there is your fuel pump needs replacing if there isn't then check the wire harness for a break in the wire. please rate

Starting Problems with a 1995 chevy astro 2wd 4.3 L


The fuel pump might be going out. Did that mechanic do a fuel pressure test/tests? Sometimes the pump might be acting up when it's going out. Off hand, I don't know what it could be.

Fuel Pump Relay


Obviously, you can jump the relay but it is dangerous on an extended basis. You'd have pressure in the lines when you don't want it there. Replace the relay if it is defective.

If you have other issues, you can check the pump back to the tank by going on the business end of the relay and looking for resistance at the pump to ground. If it is open, the pump or the harness is bad...GMs have harness issues...not Fords.
