The built in factory anti-theft system disables the fuel pump if it is triggered, or this can be caused by a fault in the anti-theft, those are a few of the reasons, arm and dis-arm anti-theft is it working properly? Follow this procedure to check security system:

The Security System is reset by unlocking the driver's door twice with the Ignition Key, but if it does not reset, most likely the Ignition Lock Cylinder has failed. It has small contacts which 'sense' the pellet on the key and transmits that data to the Anti-theft Module. Often the contacts, or the micro wires, break causing the module to think you have no key in there. The ASR may be illuminating since the Security System is active, trouble codes?

SOURCE: put new fuel pump, fuse, and relay in 1998 chevy

Did you check the ground wire on the frame. There is a ground wire that is bolted to the top frame rail near the left rear wheel opening. I've seen that wire break or get corroded where it bolts to the frame. I'm not sure of the location on a 1998 but that's where it is on the earlier models as well as the full size trucks. That wire also grounds the gas gauge, does the gas gauge read goofy? Also keep in mind the pump only runs for 3-5 seconds then it shut off, until the engine starts, or the starter is engaged. Good luck!

SOURCE: i was having problems with

I have worked on quite a few chevys and can tell you what I've found to work with this type of problem. When you replaced the starter, did you tug on the fusable links that connect to the solenoid to see if one of them was burned and loosing power? There are two or three short pieces of fusable link attached to wires that power the fuse block and other electrical circuits at the solenoid / battery cable connection that will stretch when you pull on them if they are bad. If they are, then you won't have power for the fuel pump, relays and other circuits to make the truck start.
If one is bad, cut the wire behind the link connection and put a **** splice and piece of wire on it with a ring terminal,and connect it to the solenoid. Turn on the ignition and listen for the fuel pump to buzz. The fuel pump is controled by the ECM and makes the pump turn on for 3 seconds to prime the system with fuel before starting the engine. One of the wires on the solenoid with a fusable link does this. If this works, your done.
If the truck won't crank when you try to start it, check the "S" terminal for power with a test light while someone turns the key. The "S" terminal on the solenoid comes from the ignition switch, to the neutral/backup / clutch switch to the starter. You'll have to check every point in between these for power to locate the problem. One bad connection or part will keep the starter from getting power to the "S" terminal. You can use a screw driver to test if the starter is working by touching the two terminals together.
While your under the truck, look at all the wires in the harness for any chafing or rubing, I once found a wire that rubbed through and was causing the problem.
Hope this helps, Craig

I have a 2007 chevy impala. I replaced the windshield washer pump and checked/replaced the fuse. I get a 12V spike to the pump when trying to wash the window and then no voltage. Is there a relay som


there is no relay.
- check if there is dirt in the water tank which might stuck the pump and blow the fuse.
- also check all cables to the windshield washer pump if they are damaged and cause a short somewhere.
- or the wiper switch in the dashboard might be faulty? http://www.vadengmpp.com/owners-manual/chevrolet/2007-Chevrolet-Impala.pdf

2007 chevy silveado 5.3 12000 miles on it Started


Is this a 1500 Silverado? I looked at my database, didn't see pcmb fuse? These databases are not always correct. On some gm makes and models, the pcmb fuse supplies voltage to both the pcm and fuel pump. Unplug the fuel pump, see if fuse still blows? If it does, it's not the fuel pump. Can't rule out wiring circuits? Has this vehicle sat for a long time?

No fuel pressure. checked the relay and fuse. no pressure at fuel rail so I replaced the fuel pump still no pressure.


if the fuse and the relay is good then you will have to check the powers and grounds at the connection for the pump at the tank.have you replaced the fuel pressure as if its plugged you won`t get any pressure.i trust you checked the pressure with a gage as just pushing on the schrader valve is not checking the pressure.

No power to fuel pump car was running fine just quit repalced fuel pump no power to pump, car will start when spraying starting fluid in to intake, is there a fuse ? also replaced ECM, fuel filter,...


Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

I have a 2004 Chevy Impala it has poer at the fuel pump fuse and fuse looks good but no power at fuel pump. is there a fuel pump relay switch or what could it be?


First make a set of jumper wires and jump the pump from the battery and see if it works. If it runs its the relay or the ECU,or the ignition switch.
Remove the relay and test it for B+. Then jump the terminals and see if the pump runs. If pump runs and you got B+ up to this point its the relay.
However,if no B+ at the relay means ECU not giving relay the turn on signal..
While wearing a ground wrist strap check out ECU Grounds and B+ wires for continuity from Ignition switch and other areas of interest (use shop manual)
either the switch is not telling ecu to send message to relay to turn on the pump or someone in this circuit has gone bad.

No start 09 impala 30% fuel in tank hear pump run fuse/relay good


This is still a new car try not to do anything to void warranty. I know if you could get to run most likely would drive it to dealer. When your spraying the choke cleaner it is going directly into the intake to the piston area, fuel from the tank must go through the injectors which are electrically controlled, before making it to the pistons. Due you have power to the injectors when motoring the engine over. Remember you must have a very strong battery on todays new cars when attempting start it has to turn quickly. Check wiring diagram to see where injector harness power feed comes from and follow back. I hope this helps God Bless

01 chevy impala. power mirrors and gas gauge not working


Check all fuses and relays. As far as the gas gauge, you may need a new fuel pump, fuel pump relay, or the float on the fuel pump is loose or came off from ear and tear.The mirrors: check the fuses; also, check, or have the button panel in the door checked to ensure the connection are secure. May need a new switch for the mirrors. I am not familiar with this vehicle; but this is what I suggest doing to solve the issues.
