Check your fuel pressure regulator. Remove the vacuum line attached to it and hook a fuel pressure gauge to the schrader valve on the fuel input line. The gauge should read at least 40 PSI, probably closer to 50-60 or more.

If it's lower than that, you're not getting enough fuel to the engine. It may also be stuck shut, meaning that you're putting in too much fuel.

If you find that the exhaust smells of fuel after cranking for awhile, there's a good chance that you're flooding out due to a faulty FPR.

My GMC Sierra ran out of gas and now I can't get it to stay running.


Fuel injectors require a high pressure fuel pump which is located in the gas tank. The gas serves as the lubricant for the pump, so wen you ran out and emptied the tank completely you no longer had lubricant and the pump burn out. It won't pump gas now because it's the fuel pump is burned out and needs replacing. It runs when you put fuel in the injectors as that bypasses the pump. Replace the pump and the never let the tank get below 1/8th full (half a 1/4 of a tank).Not lie the old low pressure fuel pumps on the side of the engine blocks. Not cheap to buy a fuel pump and have to drop the tank to replace the burned out one. $$$ in costs even it you do it yourself.

Ran out of gas ran fine for about 2 days went to friends when leaving it died,started right back up,but shaking real bad like a missfire,checked and seems the coil packs r ok,


Sounds like something in fuel system is clogged form running to low on fuel if vehicle is old and fuel filter has not been replaced for a long time.
It does not take much but a small particle to clog injector or it could be fuel pump is going out. You need to check fuel pressure and change filter and also you might have to get fuel system flushed and you might just have replace injector at worst. Hope this helps

93 tracer lost power on highway while driving, i checked the fuel pump switch in trunk then checked gas filter hose and cranked gas came out so not fuel problem then i checked to see if i have spark a


Clogged air filter ? Needs air into the engine also ,plus compression . Are the fuel injectors spraying fuel into the engine ? Try spraying starting fluid into the engine through the throttle plate and seeing if it starts then ? If it does ,fuel injector problems .

Why does my van start, but engine dies within one minute? We have replaced fuel filter and van ran fine for about 4 days and now it will start, but dies shortly after.


Brandy, being that the filter helped for a few days, it is probably fuel related. Gas goes from the fuel pump to the filter, through the filter to the gas lines, from the lines to the injectors, and to the engine. You need to make sure the fuel pump is working properly. It should run at 12 volts. It may need changed. Check your gas lines and make sure none are damaged. I don't think it is the lines, but it doesn't hurt to check. You may have bad fuel injectors. They will need checked as well. Fuel pump, filter, lines, and injectors. These are your fuel system. When you have a fuel issue, these are what you check. Thanks for choosing FixYa and best of luck Brandy.

Not starting ran out of gas,added gas and still not starting,can hear fuel pump running,smell gas at engine and exhaust.


Gas line filter may be dirty and clogged. Change it. There could be sediment or dirt in the tank that you drew up to the filter when you ran out of gas and it has built up and is blocking gas from getting into the engine.

I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.

I would check the fuel lines themselves and make sure there is no blockage. If not you might want to check your fuel injectors and see if they need to be replaced. also make sure you didnt install fuel filter backwards.

Help w 1994 chevrolet truck


This injector set-up needs a specific fuel pressure supplied to the fuel rail to even start, much less run properly. The fuel pump is immersed in fuel inside the gas tank to keep it cool and not burn up. Running the fuel level low causes more heat in the pump and interuptions in proper fuel pressure. AC/Delco pumps have proven to be a reliable fix, the aftermarket pumps only last for a month or two sometimes. Check fuel pressure under the hood and power and ground to fuel pump at electrical harness at top of gas tank. This truck needs a fuel pump.

fuel pump died replaced it truck ran poorly afterwards. Had a prussuer test done pump determend pump was no good. Put in another ran good for 2 days started running poorly hard to start no power. 2nd fuel pump. So i figure another bad new fuel pump wow changed it put in a third brand new fuel pump. Still will not eve start now. I had it tuned up 2 months ago new plugs rotor, cap, etc. put in a new fuel filter made sure it is on proper checked all connections for leaks. this cannot be a fuel pump problem now. no problem with the elctrical i figure i have great spark on ignition tester. I can hear the fuel pump prime when i turn the key. but when i went and checked the fuel port i had no pressure. When it is being cranked gas sews out of the test port. Also i dont if this is comon cause i used to turn my keyand go. but when i have someone turn the key and i listen at the gas tank whn the key is shut off i hear gs spraying back into the gas tank. So i am open for opinions.
