How do you know it's the fuel filter and not the fuel pump or a bad vacuum hose? If it's the fuel filter why don't you just change it?
Unless you know how to avoid gasoline everywhere take it to a friend's mechanic.

Engine runs 15 or so will shut off and starts when cool. Replaced fuelfilter and fuel pump relay. still does the same thing.


If you don't have any check engine warning light on your dashboard relating to EGR system means it has to be the FUEL PUMP according to you fuel pump relay and fuel filter was replaced but the most common cause by that is fuel pump...to verify have you try to install Fuel Pressure Tester to a fuel line it might not be the specified psi while observing the tester a several minutes tester shows it dropping down the pressure till it shut off by itself.

My 86 ranger keeps shutting down It has good fuel pressure New fuel pumps Will turn on then shut down What's going on? Could it be the distributor ?


Good fuel pressure from the pump is fine, at the pump. But if it can't flow constantly it WILL shut down. Have you though about changing the fuel filter? even a dirty fuel filter will allow enough fuel to the engine to allow it to run for a few seconds or so. When that little bit is gone, can't get enough to still run.

1998 gmc jimmy 4.3 vortec starts and runs but shuts down when reaching operating temperature.


Your fuel filter may be at it's life time and will need to be replaced. Start with the simple and replace that, the other thing also that would cause the engine to shut down would be a faulty oil pressure sending unit. What is the oil pressure on the dash when the engine shuts down. You need at least 8 PSI to have the engine stay running. Check your Fuel pressure at the shredder valve and you should be 62-65 PSI with the engine not running and fuel system energized, once the engine is running it should drop about 5PSI. The last thing that could cause this would be a bad ICM, once the ignition system heats up the ICM fails and the engine shuts down. A mentioned, start with the simple and replace the fuel filter and check your fuel pressure to ensure your fuel Sending unit has not gone bad and will need to be replaced. Good luck and keep me posted.

Car would not start so replaced battery, then alternator; Ran great for roadtrip then shut down on the freeway. Can hear the fuel pump, so replaced the fuel filter; has spark. Has fuel. Wires are in good...


WHEN A CAR SHUT DOWN ON HIGHWAY OR FREEWAY.YOU CAN STILL HAVE FAULTY FUEL PUMP.IT COULD BE RUNNING BUT THE FUEL PRESSURE CAN BE TOO WEAK.THE 2.5 ENGINE FUEL PRESSURE IS 6.0 TO 7.0 PSI AND THE 3.3 ENGINE FUEL PRESSURE IS 37 TO 43 PSI. ANOTHER THING CHECK TO MAKE YOUR COOLANT IS NOT LOW.LOW COOLANT CAUSES ENGINE GET TOO HOT SHUT OFF.CHECK PVC VALVE AND EGR VALVE MAKE SURE THEY ARE NOT STUCK OPEN OR DISCONNECTED.AND MAKE SURE IDLE SPEED IS NOT TOO LOW YOU IDLE SPEED IS ON THE FACTORY STICKER UNDER THE HOOD.

Engine shuts down anytime gas pedal is floored corvette is a 1982 crossfire.if you ease up on pedal engine then gains rpm as normal.idle is fine .seems as if when vacuum drops that is what causes it to...


Possible causes, and in an order of where to check first:

1.Fuel filter - Located along the Right frame rail, close to passenger door area.

2.Fuel pump - Located inside fuel tank.
[Electric fuel pump. Pressure should read between 9-13 PSI.
The Cross-Fire Injection unit, is in reality,
Two- Throttle Body Injection units. TBI. ]

3.Fuel strainer for fuel pump. ('Fuel sock')
Located in fuel tank, attached to fuel pump.
The fine mesh of this sock can become restricted over time, by 'sludge' that has built up in the bottom of the fuel tank.
(
'Sludge'. Dirt mixed with moisture that builds up inside a fuel tank. Additives for gasoline that also add to the sludge)

4.Air cleaner element. (Added, because many times this is overlooked by the owner, and can cause bogging down when accelerating hard, if severely dirty. Added as fourth in the list instead of First, but may be the First area to look)

5..Cross-Fire Injection System, (Twin Throttle Body Injection System)
This injection system is controlled by an ECM, (Engine Control Module)
This same ECM also controls the emissions system. (CCC. Close Coupled Catalysts)

It is for this reason, of interaction of the injection, emissions, and ignition systems, that only a qualified, professional technician can diagnose problems with the unit.

Computerized diagnostic equipment, along with the knowledge, and training required, is needed.

The Hombre cuts off without warning while driving. Then it cranks back up.


sounds like a fuel filter problem, when the engine shuts down,the blockage settles, then when driving, the fuel pump draws the blockage back.......check fuel filters

Check the fuel system. Cheap first....fuel filter. Then the fuel pump. The engine does actually turn over, but it just won't start...correct?

Engine shut down


Sounds like the fuel pump is the most likely suspect. The fule filter could also play a role in preventing the fuel under pressure from reaching the engine going uphill. If you haven't changed the fuel filter recently, change it either way, then you can rule it out if the problem persists.
