Check the fuel pump fuse, should be under
the hood on the drivers side(98+ models)
Make sure the battery is putting out enough
voltage. Then check the fuel filter and the
fuel injectors. Finally look at the fuel pump
its self.

I have a 95 Chevy 1500 truck 4by 4 and I can't get it to start I tried everything it seems like it wants to start but nothing what could it be

well if it won't start it won't start...because your engine has lost 1 of 3 things that make it run: gas, spark, and compression. Don't tie yourself into knots over what it could be. Do the basics first. 1.Check that the engine is getting gas into the cylinders.
2.Check that the spark plugs in the cylinders are getting ignition current to make blue snapping sparks when tested.
3.If you have both spark and gas to all cylinders, you should do a compression test of the cylinders to know there is enough compression in the cylinders to make it run. Without good compression readings from all cylinders, no amount of money thrown at it will make the engine run better, you have to do mechanical repairs to the engine that restores compression first.

Most times, sudden no starts are gas or spark related. Check those first. Happy Holidays.

Why is gas shooting out of spark plug holes when cranking it over

How long you been cranking it? You know every time you crank the engine over, the injectors are pulsing and spraying gas into the cylinders. If it was cranked a long time, you may have gas collected in the cylinders. Let it sit a bit so the gas dries out. If too much gas is getting into the cylinders, check your fuel pressure. If too high, the fuel pressure regulator may be bad.

Getting gas smells and misfiring on a 2000 chevy venture. what might be the problem? was told not running on 2 of the 6 cylinders could that be the only problem? i am being told its something else

first off you have to fix the misfire problem before you can do anything else,as a misfire will cause a fuel smell because you have 2 cylinders acting like a raw fuel pump ,by the fuel entering the cylinder not burning a being pumped out you have to find out why it is your six cylinder car is only running on 4 cylinders and repair the problem.then you can go from there if you have to,also you will have to change the oil as it will have fuel in the oil which thins out the oil to a point it does not do it`s job and could ignite in the oil pan causing other problems

Started running bad suddenly. Had to feather the gas to keep it running and get home. Started it the next day and let it warm up for about 8 minutes. It died and won't start. Acts like it's not getting...

Take out the spark plugs again, put a little bit of oil down each cylinder, see if that helps. If it does, you might get a compression tester to check to see if one of the cylinders has lost compression (EG, a head gasket blew, etc ...)

Gas in oil

Usually gas gets in the oil if you are having a hard time starting the vehicle, or turns over for a long period of time before firing. It floods the cylinders and bypasses the rings filling the oil with gas. You may want to change the oil and filter and see if this problem continues. Check your plugs, wires etc.. If it does then your rings may be shot not giving enough compression to the cylinder causing un burnt gas. Try a compression check and see if you have any bad cylinders. Depending on the vehicle 90-160 psi isnt uncommon. If there is a great differential between the cylinders you may have faulty head gasket, bad valves, or just worn rings.
