50 - 62 psi fuel pressure ! Yes this could be a fuel delivery problem ! It could also be an ignition problem . Take some can spray carb. cleaner an spray in the throttle plate. an see if it keeps on running, if so ,you have a fuel system problem. Do you have a check engine light lit or any other light, security light flashing or on solid ?

SOURCE: 1998 Chevy tahoe Hard to start when cold

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

SOURCE: Chevy S10 starts and then shuts off.

well i would try squirting fuel into the throttle body when it is in its not running mode. if it starts and runs you know the fuel pump is at fault .. or its not getting the right fuel pressure from it..

SOURCE: fuel leaking into vacuum line on fuel pressure regulator

If you have fuel on the vacuum side of the reg, that means the reg is leaking,causing a variaty of drivabiliy problems. Replacing this reg is very straight forward. Just add a little lube to the O-ring on the reg before installation. Good luck.
Yours Moe.

SOURCE: 1987 chevy s10 2.5l tbi will not start. changed

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

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.

Vehicle starts runs for 1-2 minutes then quits, Starts right up. Fuel is being shut down.


Also what no one is mentioning is to make sure you have oil pressure, or that the oil pressure sensor is working, alot of newer vehicles run the fuel pumps off of them oil pressure sensor so if your vehicle stops pumping oil and lubricating, it shuts the fuel pump off to protect itself from damage or further damage

Sounds like you are losing fuel pressure or the ignition module is shutting down when it gets hot. Check for spark when the car is in the no start condition. If spark is ok then install a fuel pressure tester and let car run. When it dies the pressure should be less than 15 psi. You may need a mechanic for this. Best possibility is that you will need a new fuel pump or ignition module.

I have 2003 ford expedition,when engine is cold my expedition is hard to started... what should i do..


Sounds like you have a fuel pressure issue. These trucks are bad about bleeding all the fuel pressure off when the engine is shut of but will run fine when started. the only good way to check this is to install a fuel pressure gauge on the shrader valve on the fuel rail. Once you get it isntalled start the engine and let it run for a minute or so,shut the engine off and it should hold pressure,if it bleeds off quickly it means the check valve on the pump is leaking and it will need a fuel pump.

you need to check this when it does not start fuel pressure at the fuel rail , spark at the plugs, power at the fuel injector wire that will tell you whats wrong . if there is no fuel pressure its a bad fuel pump swap the relay with another one to test it if still no pressure the pump is bad . if you have fuel pressure and wont start spray starting fluid in the throttle body see if it starts this tells you if its spark or fuel if it does not start its spark possible bad distributor or coil if it does start that means you have spark and with fuel it will run meaning your injectors are not firing = no power at injectors = bad crank sensor its 38.00 at auto parts stores driver side top of trans bell housing make sure you push and hold it down when tightening the bolt

does it have three second fuel pump run when you turn key to run position/ in between you should let i rest 5 or so seconds then try it again also some of these cadilacs have oil pressure sending unit wich takes the duty of keeping fuel pressure up is fuel pressure lowering as engine quits eg. rev up some in your few seconds of running while the engine is quit momentum keeps it turning for a short time see if you r pressure maintain thru the wind down

The most common cause of this condition is the check valve in the fuel pump failing, to check this hook up a fuel test guage to the fuel rail test port, run the engine for a moment and shut it down, after shout down the pressure should stay within 5 PSI of the pressure at shut down after sitting overnight, if it doesn't then the fuel pump must be replaced, the reason is the fuel drains back to the tank if the valve is defective, so you get air and no real pressure on cold start, A check of pressure on a hot running engine will not show this fault, also make sure you are usine the correct Octane of fuel, Prem fuel in a regular fuel engine will cause cold start and stalling issues in cold weather.

1990 Dodge Omni. Runs but shuts down


Check to see that you have good(bright orange) spark to the spark plugs the next time it dies... if not odds are its the coil. If spark is good check fuel pressure, since the pump was replaced if pressure is bad the fuel pressure regulator would be in question.

Motor shuts down


Have you checked/tested the fuel pressure? sounds like a bad pump and or plugged fuel filter, check the pressure, if it is low replace the filter, if that still doesn't help you will need a new fuel pump, it is located in the fuel tank.
