The fuel pump has a check valve in it; if this has failed it can bleed back. Also the pressure regulator may have failed; this too may allow the fuel pressure to drop off. Lastly if you find low pressure and the truck flooding the injectors may be worn and leaking.

I hope this may have asssited you,
Best regards,
Tom

I have a 97 grand cherokee larado and when I shut it off it won't start back up for a few mins..then it fires up...is there a kill switch on it or something else wrong possibly


No kill switch. You may have a fuel pump pressure issue, it may being losing pressure after shut down due to a faulty fuel pump check valve. Do a fuel pressure leakdown test, start the engine with a fuel pressure test gage hooked to the test port on the fuel supply rail to the fuel injectors, looks like a tire valve. Start the engine and run it and check for leaks at the pressure port to the test gage, repair as needed, once you are sure the test gage is leak free shut the engine down, if the fuel pressure bleeds down very quickly then you need to replace the fuel pump.

I have a 1995 Chevy k1500 when I use les then half gas it is nice a smooth and idles smooth but when I go over half it loses power and when I let up the power comes back I have changed Cadillac converter...


Sounds like you are losing fuel pressure. At low rpms it will not show up. Could be a bad fuel pump. Since you have spent so much money I highly suggest replacing fuel pump. Also check for any fuel leaks. I truly believe their is a leak in vaccuum A thumbs up would be greatly appreciated if this answer is helpful 1995-chevy-k1500-when-use-les-half-ynnexffib1tqqlzbw4nudlh0-2-0.jpg

2003 Town & Country hard to start. Once it's starts it will start every time . Wait a few minutes then it's hard to start. Must turn over three or four time to start.


It sounds like possibly a fuel pump issue. The pump may be losing its prime because of a sticking check valve in the pump. Instal a pressure gauge and watch the fuel pressure after shutting the car off. The pressure should not completely drop off it should only drop a few pounds. If it loses more than a few pounds of pressure quickly then it may need a fuel pump. This can also be caused by leaking fuel injectors so further diagnosis is needed to find the source of the leak

Wont crank on frist try


It would help if you were a little more specific with the year, make, model. etc. but usually with the newer fuel injected cars, excessive cranking means that the check valve on the fuel pump at the fuel tank is leaking. When the car sits the pressurized fuel rail at the engine loses its pressure due to the check valve leaking and you must crank the engine several times to build the pressure back up.

94 lt1 cranks a while before car starts. When car starts the car runs fine.


You may be losing fuel pressure. There is a fuel pressure regulator in the fuel line. It has a check valve in it. If the check valve is bleeding off then you have to get fuel pressure pumped back up. You can verify by turning the key on and letting it sit for about 5 seconds, turn off and then back on and repeat 3 times. This will pump fuel back up to the regulator and should start right away.

Have a long crank time ususally wont start but does sometimes. i have replaced lift pump. i think it is either the injectors or the pressure pump what do u think.


Hi,it sounds like you are losing prime.I would look for a leak between the lift pump and the fuel tank.You may or maynot see fuel at the leak,It might be sucking air alowing the fuel to drain back into the tank.Your high pressure pump should have caused a performance problem and set a code.Hope this helps.Thank You for using fixya... iluv2fish..........Ray.......

I have a 87 mustang and it has a mr gasket electric fuel pump. It vapor locks all the time. i have to take fuel line off turn switch on let fuel pick back up then plug the fuel line back up and it will...


Actually vapor lock refers to a condition in the intake manifold on a carbureted engine. You don't have vapor lock. What you may have is a filter inside the tank, its nicknamed a sock. Its a fine mesh screen and may be plugging up. When you pull the fuel line the fuel flows back and unblocks a small section , until it starts too **** again and re plugs. You may also have fuel pump that starts to lose power when its gets hot. Lee

2000 Bravada hesitates when starting frm a stopped position.


get your hands on a fuel pressure tester.. this will tell u if u are losing fuel pressure between starts... those 4.3 v6's have a big problem with the poppet valve (injector assembly) leaking. causing the engine to flood...and losing pressure to push threw the injector... causing the hard start...but the fuel pump module will also lose pressure as has a check valve to keep that from happening but from time to time they do leak allowing fuel to flow back into the tank...with this pressure tester, have a friend turn the key to on.. after you hear the fuel pump shut off immediately pinch off the two fuel lines going from the tank to engine you can find these right below the driver side door. you will find the fuel filter there which is the pressure hose the other hoseis the return... both rubber hoses that will not be harmed by the vise grips or tools be your choice the other metal line is a vapor line which is not important. after you do pinch the lines off check the fuel pressure if it still drops with no signs of slowing down then the poppet valve is defective...if it does not move then you know it is definitely the fuel pump module (fuel pump assembly)
