Then it probably isn't your fuel pump. sounds like a spark issue to me. try your fuel filter first. if not, i think you have to drop the tank, or there might be access to yours in the truck/rear seat.

Usually fuel pump doesn't cause this fail. Most probably ocludded filter. you must change each two oil changes. Open hood in a safe place as as dark as you can. Turn on car and see if you can see sparks jumping from cables or distributor case. It mean cables or spark itself must be replaced

95 Chevy Caprice won't start unless I disconnect the fuel line.


Fuel pump can also cause this problem, You find out if fuel pump is faulty by energising directly fuel pump, and checking fuel pressure.

Check also the fuel line, starting from gas tank, often oxide and dirt from tank can obstruct the hose. Disconnect fuel hose and blow air into it .

Check also air filter and air intake.

Check your fuel filter again. Dirt from the tank could have clogged it again.

if you have an electric fuel pump that would explain the hum. unhook your incoming fuel line and blow the line clear, sounds like you've got some junk in your tank.it'll build up on the screen in the tank then fall off (at least partially) when your making turns or hitting bumps or holes. next time it's only got a gallon or so of fuel i'd drop the tank and check the pickup tube inside. sux but that's the only way to get to it. while you've got the tank off and out from under the jeep, might as well clean it out real good and replace anything inside (usually the screen) that doesn't look right, dirty etc. wouldn't hurt to run a bottle of fuel system cleaner in the next full tank of fuel either. preferably as soon as you put your tank back. good luck

Cutting off while driving


Try checking fuel pressure again with a guage on the fuel rail. If you still notice the pressure is low and you know the fuel pump is good, the fuel pressure regulator may be bad. Sometimes you can tell by unplugging the vacuum hose from it and if you see gas that means the diaphram is leaking. If everything checks out with the fuel system a bad EGR valve or EGR valve solenoid can cause cars to sort of stall under half throttle. Good luck and keep me posted.
