Where is ecm on 95 gmc jimmy


The ECM on the jimmy, is located on the passenger side fender well by the overflow tank. But before replace the ECM, inspect the fuel pump and fuel pump relay. The ECM sends power to the fuel pump relay and if the relay has gone bad will cause the fuse to blow which will kill the the power to the ECM, in turn kill the electrical power to the ignition system.

Start by removing the fuel pump relay and swap it with another relay and see if the fuse will blow again, if is does. Disconnect the fuel sending unit wire harness at the frame and see if the fuse blows again, if the fuse stays good. Chances are your fuel pump has gone bad or the fuel filter is dirty/clogged causing your fuel pump to draw more amp and will need to be replaced or the wire harness from the frame to the sending unit has a short which is common on older Jimmy's.

Here is a link to the electrical harness throughout the Jimmy.

Car was running great,cut right off at stop light. i have no fire goin to fuel pump.trying to find relay & or fuse.


There are a couple of issues that can cause this. Dodge use a double fuse system for the fuel pump. One fuse is located in the interior fuse panel, mine was in slot 13 but that was a Neon. The other fuse and relay are located in the engine compartment in the power distribution center. Now, having said that I will tell you the bad news. If the timing belt broke, a definite possibly in an 87, the fuel pump is shutoff due to a safety. Check the timing belt. You should be able to look at it visually through the cover and tell if it is turning. It will take two people if you don't remove the cover which is help in place by 2 bolts on a 4 cylinder. Before you go getting into all of these fuses and wiring use a multimeter to check the power wires going to the fuel pump AT the gas tank. If you have power there and the fuel pump isn't working then the fuel pump has gone out.

HAVE A 96 ACURA TL 2.5 , WAS RUNNING FINE NOW IT HARDER TO START AND RUNS ONLY FOR MINUTES WHEN YOU PUSH THE GAS IT TURNS OFF. HOW CAN i TELL IF ITS THE FUEL PUMP OR RELAY SWITCH? PLEASE HELP


You will have to have a fuel pressure test done on the vehicle ,but it is either the fuel filter,or the fuel pump witch has gone out,it is not a relay,or fuse,or the pump would not work at all.Replace the fuel filter and see if the engine performs correctly .If the fuel filter helps,but the engine still runs poorly,replace the fuel pump,if the fuel filter went to long,being restricted,it will wear out the fuel pump.

Fuel not getting to intake


check to verify there's fuel pressure at fuel pump, always check for blown fuses first. if the fuel pressure is not present at the fuel rail then the pump is bad, providing that all fuses are good.

Where is my fuel pump relay on a 1996 chevy blazer? I changed out my fuel pump and the blazer still will not start


Its in the fuse panel under the hood the cover will tell you where it's located.You also may need to replace the crankshaft speed senser,if it's gone the relay won't work.If you listen and hear no fuel pump running when the key is first turn on then it may be a relay issue or the wireing to the fuel pump.

I think my fuel pumps gone??


Stand outside your car when it's quiet. Turn the key on (so the dash lights come on), and listen. You should hear almost like a buzzing or humming sound from the back of the car. Thats the fuel pump pressurizing the fuel system. If you dont hear it, the pump's not working. Check your fuses first, the fuel pump does have a fuse in the fuse box.

1993 Jeep Grand Cherokee Fuel Pump?


I don't remember seeing any fuses for that on the one I have...It's dark out now and I don't have a light that is working out there. I;ll look tomorrow but like I said, don't remember seeing one, and I've been through that system hundreds of times. Only two palces it would be is in the power dis center near the battery or in the under-dash block. If the relay failed before, it was likely because the pump draw was too high, so youre on the right track.

I have a 2000 ford focus and there was a recall for a defective fuel pump. THe dealership replaced it for free. You should check Ford recalls for this problem.
