IF YOU HAVE A 2 DOOR, THE HANDLE IS ON THE WINDOW, THEY BEND, AND BEND, SLIGHTLY UNTIL THEY BREAK. YOU MUCH REPLACE THE ENTIRE UNIT, NOT JUST THE HANDLE THAT MOVES. WRECKERS WILL TRY TO SOAK YOU FOR A LOT OF CASH FOR A USED ONE, BUT YOU CAN GET AN AFTER MARKET UNIT FOR APPRO. $65.00.

Check the oil pressure/fuel sending unit on the oil filter case,,,if the unit is no good or there is a bare wire there it will make the fuel pump run all the time,,even when the key is off,,had the same thing happen to me.

Can't help with the fuel pump, but as for the doors, I had the same problem. The whole handle will need to be replaced as there is a part broken internally and it's pot metal, so a weld won't hold. Let me know if that's the case!

Fuel pump fuse always blows


disconnect the fuel pump and place a new fuse in the holder if it still blows go back to the relay and disconnect it and fit a new fuse. In the first instance if the fuse stays good the replace the fuel pump as you have a dead short in it.. If it blows at the relay replace the relay as the short will be there.

I have a 03 Hyundai accent I just replaced the fuel pump I have no power to the fuel pump I've checked the fuses and the fuel pump relay it won't start I'm not sure what to do next


Do you have a test light? If not, go buy a cheap $5 test light-one with a lead to clip to a ground, and with a needle type probe.
Pull the fuel pump relay out of the terminals it is plugged into-you need to check if the power feed for the pump is still available at the relay. Clip the test light lead to a ground and touch the test probe to the positive battery post-to check that your ground is good- tester should light up. Now touch the probe to all of the terminals that the relay plugs into. One terminal should have power with key off. If no terminals have power, you have lost the power feed for the pump. Double check all your maxi fuses in the power distribution box. Either a maxi fuse or a fusible link will be the power feed for the fuel pump relay.
If the power feed is there at the relay, try a new relay. If still no pump, a shop will probably have to check your fuel pump circuit.
Did you check for power at the fuel tank while the key was held in crank? When the engine is cranking, the fuel pump wire should have power. When the key is turned to on, the fuel pump should have power for about 2 seconds, to pressurize the fuel system. Then when key is turned to crank or start, the fuel pump should stay on.

My fuel pump isnt getting any power to it at all and its brand new. My car will turn over but it won't start..HELP..also we've tested the relays and the fuse.


If the fuse and relays are good, then it is most likely a wiring problem.

First using a test light or meter, make sure you have power to the fuse when the ignition is on.
With help from someone, make sure the relay is engaging. This can be done by feel (should be a faint click when engaged) or with a meter.

From there, trace the wiring to the fuel pump.

WHERE IS THE FUEL PUMP ON 2000 HYUNDAI ELANTRA IS IT THE Tank


Yes, it is mounted on top and inside the fuel tank. Look for an access panel above the fuel pump inside the vehicle. If there is none then you will have to remove the fuel tank in order to replace the fuel pump. Make sure to install a new fuel filter if applicable. Before removing the fuel pump, replace the filter, check the fuse, and fuel pump relay. You can hear the pump run for a few seconds after turning on the key without starting the engine. Open the fuel filler door and remove the fuel cap. Have someone turn no the ignition, and listen for the pump. Even if you hear it run that does not mean it is ok. It may be very weak.

I have no power to the fuel pump on my 1996 TBird. Where is the fuse for the fuel pump located.


Do this test first. With the drivers door opened in a nice quite area turn the ignition key to the ON position without starting the engine. You should hear the fuel pump operating for 5 seconds which is priming fuel to the engine. If not heard the engines oil pressure sensor is at fault. The third wire from this sensor links to the fuel pump to prime. When the engine reaches normal operation oil pressure range the computer shuts off that circuit and turns on the fuel pump relay for the pump to run. That relay stays on until you shut the engine off

Replaced fuel pump failure


If you can't hear the pump over the door chime, when checking, roll down the window instead of opening the door, or have someone else listen outside the vehicle! To get the relay out, spray some wd 40 or other solvent around the base... it will seep into plug and make it easier to remove. (if it's bad, it will have to come out sooner or later!!)
Did you replace the filter when you did the pump???
