One thing to check most people miss is the ground from engine to frame or negative side of the battery to frame. ive seen alot of problems of the braided ground wire breaking and the pump doesn't get enough contact with ground to run the full power. also check the oil pressure sender it is a backup switch for the pump if relay don't work.can also stick your ear in the tank with gas cap off for a buzzing sound.if it isn't smooth sounding check the ground or power voltage.

1995 GMC Sierra 350, Truck has been idling rough.Changed spark plugs EGR valve test drove ran little better. Let sit at idle for a few moments, the truck stalled. Now will not start. Any suggestions?


I would think its a fuel problem.
Try changeing the fuel filter and the air filter but just remove that for now .
The filter is in line drivers side under the drivers door area and is not easy to do but not expensive under 10 dollars .
When you get it off and have gas all over you don't smoke .
Take a plastic soda bottle put it over the line comeing from the tank put the key on run not start .This should make the fuel pump pump if an electric pump.The pump is mesaured IN FLOW PRE MIN and its high because it has return line to the tank if its fuel injection.
So if in 10 sec. 4 to 5 ounces out put the pump is vary good .
If not the pump isn't supplying enough fuel to the system
There are other issues like the fuel injection system and the pressure regulator.
I owen a similiar vehicle you just never what will go wromg NEXT .yet my 30 old ford ranger runs like a new vehicle I fix it of course

SYSTEM WONT BLEED


diesel engines high pressure pumps not suppose run dry.diesel fuel keep high pressure pump cool and lubricated.problem could be fuel pressure regulator in the fuel filter water separator housing.replace fuel filter see if it helps problem could be fuel pressure regulator in fuel filter housing, the fuel pressure regulator has a air bleed orifice that allows vent to the fuel tank.make sure fuel pump fuse okay pump getting power. i would let garage or dealership check it out if all fails because your diesel engine fuel timing is pcm controlled if let fuel system go dry you probably have to have fuel injection timing reset or could have damage high pressure pump letting it run dry i hope thats not the case because high pressure pump not cheap part i hope it not that.

What is the best way to deal with 2 gallons of gas in 2003 TDI? I can't get a hose in deep enough to siphon it. Am thinking about removing line to fuel pump.


FOR TDI ENGINES WHICH IS TURBO DIESEL INJECTION. THE FUEL SYSTEM CONSISTS OF FUEL INJECTION PUMP WHICH DRAW FUEL FROM FUEL TANK THROUGH A FUEL FILTER NO OTHER FUEL PUMP IS USED. YOUR FUEL INJECTION PUMP HAS A ELECTRIC FUEL PUMP BUILT INSIDE INJECTION PUMP ITSELF YOU DONT HAVE TO DROP FUEL TANK.FUEL PUMP IS UNDER THE HOOD.YOUR FUEL INJECTION PUMP IS THE FUEL SUPPLY PUMP.

A 460 engine that acts like its not getting enough fuel. Will start but runs as if only on half the cylinders missing badly or such.


Check your running fuel pump pressure. If (as I suspect) it's too low, first try changing your fuel filter. After changing the filter, recheck the running fuel pump pressure. If still low, check you fuel pump pressure regulator. If OK, you may need a new fuel pump.

Also probably would be a good idea to replace you air filter.

Good luck!

CAR WONT START


If the car fired after pouring gas into the engine, then you should check your fuel pump, listen when you turn on the key, if you hear the fuel pump start and stop, then check your fuel pressure, all fuel injected vehicles have fuel pressure regulators, if your fuel pump isnt pushing enough pressure to the regulator the car will not start, and if it does start it wont operate properly, and may even leave you stranded.. If your fuel pressure is low, check the fuel filter, dirty filters restrict pressure, and are ALOT cheeper to replace than a fuel pump!

Car won't start unless we spray starter fluid in air intake


Adding a highly flammable fuel like ether shows all the other elements are in place to create ignition. Your problem is obviously related to your cars fuel system. Whether it is a pump that is not providing the fuel to your cars fuel injection system, or your fuel injector nozzles no working properly is a question that cannot be answered here. All I can do is point you in the right direction. Typically these days computer analysis is warranted to trouble shoot which sub-system of your fuel delivery system is malfunctioning.
I would highly recommend you describe your issue to a reputable garage capable of doing some system testing, and they should be able to quickly pinpoint where precisely your issue is.
