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..

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.

I need to replace fuel pump on 2000 jimmy


ok, it should be a module unit. you will need to drop the tank and get the code off the top to identify correctly (ex:fci) be sure to replace the fuel filter as this usally causes the problem. be sure to release the fuel pressure and disconnect the battery or fuel pump fuse. NEVER USE A DROP LIGHT UNDER THE VEHICLE this can cause an explosion. drop the tank and remove the unit.

Fuel pump re and re on 89 S15 4x4, 4.3 auto with throttle body fi


Unfortunatly, your fuel pump is in your gas tank. It is part of the sending unit. You will need to siphon out the fuel and drop the tank. You may have to replace the tank straps and fuel llines depending on thier condition. It should take 3-5 hrs depending on what you need to replace.

Fuel pump need replacing


drain the fuel out of the tank and remove tank. Be careful not to brake lines that are connected to top of the tank. disconnect lines and wire for fuel guage and fuel pump. use a flat bar or sutable tool and rotate the odd looking lock nut counter clockwise to the first tab and pump will lift out of tank. reverse procedure to install new pump. (while pump is out it would be a good idea to clean the tank out. You may be surprised by how much dirt and **** there will be in the tank. That is why the pumps fail. There is a screen on the inlet of the pump that plugs up causing the pump to overheat and burn itself out)

Will not start


have you tested the fuel pump yet? you do not need to remove it to do so.
if you have not tested the fuel pump yet, test for fuel pressure at the fuel test port on the fuel rail. if you have no fuel pressure, then test for voltage at the fuel pump fuse and relay. if all is well, and your final test for voltage at the weather pac terminal above the tank is good, then you should replace the fuel pump assy, or the wire leading to the pump itself in the tank. 99-01 gm vehicles have a poorly constructed fuel pump wire which tends to cause intermittent connectivity.

to get to the fuel pump, you will need a fuel line tool ( cheap and redily avail) used to diconect the snap over lines from the pump assy. there are two large straps holding the fuel tank in the vehicle, and the tank will need to be removed in order to get the pump assy out. there are two weather pac terminals on the top of the pump assy, and two fuel lines that will need to be removed. finally, the pump is held in the tank by a snap ring. after removal of the snap ring, the unit should lift easily out of the tank.
