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.

1995 GMC JIMMY WONT START UNLESS I PRIME IT THEN IT JUST DIES ITS FUEL INJECTED


It sounds like you have a defective fuel pump. The pump is locate inside the fuel tank, the fuel tank must be removed to replace the pump. Please follow this procedure to remove the fuel tank.
Disconnect neg battery cable, safely raise vehicle, place floor jack under tank, loosen gas tank straps and allow tank to slowly drop halfway, disconnect( this is the hard part) fuel lines,and power connections at tank. Drop tank. With a brass hammer/punch carefully remove retaining ring/seal.Reverse to install.A new pump module will cost you $300-$400 at the dealer. Don't use a cheap pump replace the entire assembly because this is a float/sender/pump/ in one. Replace your fuel filter too or the fuel pump warranty is voided..

I'm looking for a diagram for my 1997 GMC Jimmy. The gas tank is leaking and I want to see all the parts that I might have to order.


This is hard to say with out removing the tank, you will need a tank and sometimes the sending unit and pump while tank is down the only other thing would be the fuel lines, if the lines are rusted and dont come loose then you will neeed to make new ones, heres a couple of diagrams to help you, take note there are two style tanks depending on if you have a 2 door or 4 door, one mounts in the rear and the other on the side, i also belive you have plastic fuel lines and shouldnt have a problem with them, while the tank is out the pump asm, which comes complete with sending unit and pump should be replaced, hope this is helpful, good luck.johnjohn2_1.jpgjohnjohn2_2.jpgjohnjohn2_3.jpgjohnjohn2_4.jpg

Where is the fuel pump on a 1997 gmc jimmy


The fuel pump is located on the top of the fuel tank in most models, and it necessitates removing the fuel tank completely for access. The average backyard mechanic can replace a fuel pump in a Jimmy in about an hour.

Is there an access door any where to replace the fuel pump in my 98 gmc jimmy


I do not think so. Look above the fuel tank to make sure but I believe you will have to remove the fuel tank in order to replace the pump. Be sure and replace the fuel filter at the same time. Partially clogged fuel filters are the main cause of fuel pump failure.
