Here is an easy way to zero in on a stalling problem.
If it feels like someone reached over and turned off the key and it fires back up right away it's the injection pump.
If the same thing happens but it has to cool down before restarting it's the PMD / FSD(pump mounted driver).
If it stumbles and than stalls then it is air in the fuel lines. If it is this one try switching fuel tanks and just turn the key to run but don't start the engine. Listen to the fuel pump for a change of noise pitch. The pump is really loud when the pump is out of fuel and will have a muffled sound when pulling fuel. Sometimes the baffle in the main tank will brake away from the tank and the pump will suck air when the tank is just off full.
Also check for vacuum lock. If the fuel tank vent is plugged air can't get into the tank to replace the fuel that's drawn out. Remove your fuel cap and see if the truck runs.
Hi. It would be useful to get a code read and some live data from a decent diagnostic tool. There are quite a few possible causes including, pressure in tank - if the fuel tank can't vent pressure then a vacuum will eventually form stopping fuel getting to the engine, this will cause it to loose power and stall. Then after a few mins the pressure will drop and the process start again, easy test is when the car stalls remove filler cap - if that's the fault there will be an audible hiss and the car will start up again.
part blocked exhaust will have same problems but will more generally cause a lack of power and acceleration.
are there other symptoms? i.e only when conering or only when pulling off or stopping, engine light on/off. Jon
It sounds like you have water in your tank and/or bad gas. There are a few Chemicals that can help to remove it.... Dry Heet is one of them, but there are others. I would try to drain as much as you can first, as it seems to be floating on top of the gas. Then add the fuel cleaner. This should help. I would also replace the fuel filter if you cannot clean it out.
Switch gas Stations....
Thank you for contacting Fixya. Does this help? Let us know.
the engine is starved for fuel,are you sure you put on a big enough capacity fuel filter,they come in different capacities,or you could have a pin hole in the line somewhere letting air into the system,or the fuel pump could be getting weak,you can test this with a fuel pressure tester
Hi yes just drain the tank completely and replace the fuel filter, fill with DIESEL ;-), then just strart her up ,, it may take a bit to get going but should go in the end and run fine, Hope this helps Steve
Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.
Fuel pump,Fuel pump, Fuel pump,,, high mile cars will always out live their fuel pump. The stalls will become more frequent. But first change fuel filter if it has one outside the fuel tank, if it has it in the tank just replace the pump at the same time. Also next time when it stalls bang the bottom of the tank with your hand and try starting.
Fuel filter changed recently? If it just started this & you filled up somewhere you don't normally fill up, then I'd try some "heet" additive or similar to remove moisture from gas tank, just in case that's the problem.$5.00 test.
It sounds like you have some **** in the gas tank that is being drawn to the pickup blocking it.
Have seen this and because it seems so random, it can drive ya nuts.
You might carry a coffee can with you and pull the line from the fuel rail when this happens stick it in the can and just have someone turn the key on for a few seconds.
Beware though, it comes out with force.
Also possible is a failed fuel pressure regulator.
Those aren't expensive and . . . well, not very good either.
