Wont start also we just jump started the fuel pump and it started the stopped and hasn't started again?

It sounds like you have some dirt in your gas tank or your fuel pump has one of your fuel lines have a crack init and sucking air . Good luck and let me know how you do. Your fuel pump is proubly below the trunk floor. remove the carpet and the bolts in the floor. number your hoses and remove the fuel pump. Use a ohm meter and ohm out the pump, or take it to auto parts and they will check it out for you. [email protected]

the fuel rail has to be bled out. when you run a fuel injected car out of gas sometimes the fuel rail needs to have the air bled out before it will operate properly.

can you hear the fuel pump when you turn the ignition key to start position??( you should hear it start then stop after few sec.) If not, this could be the fuel pump fuse,some bad contact in the wiring of the fuel pump or the worst case the computer.but if you do,unplug your main fuel line to the injector turn the switch to start position again to see if you have some fuel coming out.if not this could be the fuel filter or the fuel pressure switch! hope this will help you...lipak!..

Start with changing fuel filter, then if that doesn't work, your fuel pump may be going bad.

This could be a lot of things,fuel pump pressure not enough(new fuel pump)or spark plugs and air filter need to be replaced(flooded plugs and air filter stopping up)timing has jumped,or maybe a blocked fuel filter?

When you tur the key forward do you hear the fuel pump running? You should hear a low hum for about 20 seconds near the gas tank and then it stops. If you hear this your pump is good. If it keeps running or you can't hear it at all it's bad or the main fuel pump fuse is blown.

I CHANGE CAM AND CRANK SENSOR,FUEL PUMP,COMPUTER BRAIN BOX AND COIL PACK STILL GETTING NO FIRE UNLESS I JUMP A FIRE WIRE FROM BATTERY

I HAD THE SAME PROBLEM WITH MY 1999 GMC YUKON WITH THE 5.7 ENGINE HAVING TO JUMP START ALL THE TIME TO GET IT RUNNING, THE PROBLEM WITH MINE WAS THE FUEL PUMP HAD TO BE REPLACED, EVEN WHEN I REMOVED THE PUMP AND TURNED THE KEY FUEL PUMPED OUT BUT WAS NOT ENOUGH PRESSURE TO GET AND KEEP THE ENGINE RUNNING.I ALSO TRIED STARTER FLUID, THE ENGINE WOULD RUN UNTIL THE FLUID BURNED OFF.SO THE SOLUTION FOR MY TRUCK WAS THE FUEL PUMP AND NOW ITS STARTING LIKE A CHAMP

Check to see if your alternator is charging. You can do this by having the vehicle jump started or with a borrowed battery. while the vehicle is idling, remove the pos battery pole.. if it cuts off .. then ypur alternator is bad or the charging circuit ( like a break in the line or fuse etc.)

A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech
