Was having trouble with my 1998 GMC 1500 5.7 with it dieing would restart and run for a few but got worse dieing and not starting so i took it in for a diagnostic test they said it had low fuel pressu


The fuel pump in the gas tank and the fuel pressure regulator are what controls fuel pressure-the pump builds pressure in the lines and the fuel rail on the engine, and when pressure is correct the pressure regulator keeps it constant by controlling the fuel return line from the fuel rail to the tank.
If your fuel filter is clean and not plugged, it sounds like the pump or the pressure regulator needs to be replaced. Even though the pump is working, it may be weak and failing. Some vehicles have the FPR inside the tank with the pump-You will have to check where yours is located. If it is located on the fuel rail, it can be checked to see if it is working right.
Good luck.

2004 gmc sonoma why does it take 2-3 times cranking before it starts and only does it sometimes?


install pressure gauge and watch when key is turned off to see if pressure drops to zero if so bad drain back valve in fuel pump replace it or deal with it or could be cheap aftermarket pump and has hard time building unnecessary pressure to open poppet valves between before fuel injectors

P0093 - Fuel System Leak Detected Large Leak

I would have a fuel pressure leak down test run, it may be a failed pressure check valve in the fuel pump inside the fuel tank and the system sees this as a leak. Don't replace any parts until the test is run, the part is very expensive to replace on this make of vehicle.

Changed fuel filter on my 05 Audi a4 3.0. Now I'm not getting no pressure build up by fuel rail


If the fuel pump check valve check valve is bad, the car may be unable to start. If the car does not start, turning the key so that it is one click away from starting, then repeating this process several times, may build up enough pressure so that the vehicle starts. If that is the case, the check valve is bad and needs to be replaced. check the fuel pressure regulater also. good-day ! If fuel pressure is low, disconnect the vacuum hose to the regulator. You should see an increase in pressure, if the regulator is not leaking. No change would indicate a bad regulator, check this first and get a fuel pressure reading on it to determine the pressure.

I have a 2000 Pontiac Bonneville. I have been having trouble getting it to start, but usually after 3 tries, it will start. Sometimes it will shut off while I am driving it. The service garage has replaced...


The next time the vehicle does not start you need to test fuel pressure. if you have none or very low pressure under 40psi on pressure gauge you more than likely have a faulty fuel pump or at least a fuel related problem. Based on this complaint I never would have replaced the above mentioned parts. Complete waste of money. When ever you have an extended crank issue always check fuel pressure first. More than likely it is taking a few cranks to build enough fuel pressure to start the vehicle. Watch this quick video and it will show you some basic testing for no start diagnostics. http://www.professionalfleet.com/videos/view/7-rough-run-stall-stumble-service-engine-light

I have a 2000 buick regal,3.8 that will not


u can try replacing the relay. when u turn the key to the position right before starting position which is the position it would be in when u start a car and let off key because car started, well this is somting to try turn the key to position right before starting position have sombody listing down by fuel tank and see if tey can hear pump come on, try a couple of times to make sure they can hear, also the pump will only come on for about 2 seconds each time u put the key in that position, if u do hear the pump come on each time u do that that means pump is working if so u need to build up fuel pressure which could b anywhere from 20 to 60 pressure, to build up pressure u need to turn the key to same position turn key off turn key back to that position then off and do it like 50 times each time u do that the pump is on for only 2 seconds only building a half to one pound of pressure thats why u haft to turn key somany times to build it back up, if u try that and car keeps almost starting but doesent then u need to build up a little more pressure. NOTE make sure u have gas, also most electric fuel pumps will go out when turned on dry

1996 GMC K1500 Pickup Starting Problem


i would try a fuel filter first. the fuel gauge going crazy is most likely the sender they go bad and eventually stop working. the bummer is you have to replace the fuel module. these aftermarket are about 200 bucks. the module comes with the pump and sender which is the next part you want to look at. gm has some issues with the harness to the fuel pump externaly. it actualy will melt and start to lose conection. i would check this by visualy inspecting the plug on top of the tank. unplug it and take a look. if it is at all disscolored replace the pump (module). the new pump comes with a replacement harness (make sure its in the box)hope this helps and good luck

FUEL PRESSURE DROPS WHEN PUMP STOPS.HARD TO START


The fuel pressure check valve in the electric fuel pump has failed, you will have to replace the fuel pump, it is in the gas tank, also replace the filter at the same time or the warranty on the new pump will be voided.
