You need to start with some basic testing before you change any parts. First check and see if the vehicle has spark on all cylinder, second check fuel pressure on the vehicle with a fuel pressure tester. Does it pass vehicle pressure spec. If not pump or electrical wiring/ connector is faulty. Third if all of the above is good test fuel injectors for pulse with a noid light or test light. Need more info on vehicle make and model engine size and what you have tested so far with findings.
For a quick test you can spray small amount of carb clean down throttle body and see if the vehicle will start and run off from the carb clean, if it does you know you have a fuel related problem. If not you are looking down the wrong path.

Changed alternator, belt and battery on 01 sable ls after driving for a short time air bag light and gas light come on and car

First thing is to see if the battery needs charging. If it has a full or near full charge, then maybe a loose or corroded battery cable connection is making the car seem dead..
You have to get the engine cranking at a normal rate or speed, to first see if it will start. If you get it cranking and it won't start, see if your fuel pump has failed. Best way to check that is to have the fuel pressure tested. No fuel pressure from a failed fuel pump is a major cause of a 'no start' condition.

I have a neon 2ltr automatic 1996. i changed the fuel pump and the car acts like its not getting enough fuel when its on run. cannot drive it more that 50 metres without it dying. but immedately u can...

The only way to be sure the fuel system is good, is to do a fuel pressure test. The fuel injectors require a lot of fuel pressure at them to work right. If pressure is correct, per Neon, then you can stop wondering: gas is getting to the engine and is at correct pressure, so the pump and filter is okay .
You have to start somewhere. I would say, check the fuel pressure, and check for trouble codes-have the engine computer scanned for any trouble codes. Good luck, hope you find it. Does it stall when you run the engine without trying to drive it, just sitting still?

Truck acts like its loosing all power and backfires

How's the inside of the cap and rotor ? It could be cross-firing inside the cap.
You could also have a major vac leak somewhere and the engine is starving for fuel.

5.4 cranks but dies. the battery also dies all the time

Check fuel pressure at the fuel rail with the key on. There should be somewhere between 28-32 psi on the fuel rail. If not, the fuel pump in the tank may be bad. Also check for an obstructed fuel filter. Check for a shorted alternator or voltage regulator as this would explain the constant discharge of the battery. Also, how old is the battery, if it has a bad cell, it will not take a charge nor provide 12 volts required for the electrical system and act as an electrical drain.

93 chrysler t&c awd changed fuel pump and filter, van ran fine again for about 2 months now won't start and don't hear the fuel pump. changed the oil pressure sending unit and still won

fuel pick-up in tank is blocked it has a sock over the end as a gross filter to keep out any big junk from getting sucked into the pump and causing damage to it. the sock can get so plugged up that no fuel will flow, causing the pump to run for a short time then with no fuel flow to cool it it trips the safety and shuts off

Whats wrng with my 97 jeep grand cherokee it died and wnt start bak up it turns over but acts like not getting gas. I sprayed starter fluid and it started a sec thn died.

It is not getting gas. Could be bad fuel pump,and most are now in the fuel tank.If it is the fuel pump and it is in the tank,this can be a fairly major expense.($400-$500)This is not an unusual problem,and many auto repair shops can do it.

My 1989 buick park avenue keeps dying. a friend ran a test on it and it said the fuel pump was the problem, but the fuel pump fuse keeps bowing too... Would this be a short somewhere or the fuel pump...

My first thought is that you have wires shorting out somewhere, probably right above the gas tank. Either way, you're going to have to pull the gas tank off to find it. Usually, when a fuel pump dies, it just doesn't work, and won't normally blow a fuse. Pull the tank down, inspect the wiring, and change the fuel pump if the wires check out okay.

Its posible it could be the cam shaft or crank shaft positioning sensor you may be better off renting a OBD 2 scanner and get a code that would get you closer to the problem.
