i have a 99 5.7 chevy suburban and have to use starting fluid for it to turn on , ive replaced the fuel reg. and fuel pump is 4years old fuel filter 6months old new cam and crank sensor new distrbutor rotor and cap

When this happens check for power on the s terminal At the starter while someone holds the key in the crank position. I suspect a faulty ignition switch.

There is a ground wire on the fuel tank. The only problem with that is that its on the top of the tank. The only way you are going to get to it is to pull the tank and if I went that far id just change the pump again. Sorry for the bad news man but I've put at least 10 pumps in that year and they do go out if you put a cheap on in. Hope when you had the fuel pump in you also replaced the fuel filter.

Did you put stablizer in the gas before storing it? Does the fuel pump run for 2 seconds when the ign is turned ? Have you checked the air cleaner for debris? Do you have spark? You must have air/fuel/spark to start.

if its electric shift. its probly the shifter motor. start vehicle open the door listen 4 the shifter motor. 2 see if you can hear it trying 2 shift. if not thats what it is if you can hear it tryng 2 shift it mite be vacume lines

brake caliper stuck? front brake pads. get some one to listen at the front wheels while its moving. that will at least eliminate the possibility. I've had that happen more times than i can count on diff. cars!

I have seen this type of problem before, this sounds like the engine is not getting the correct amount of fuel pressure it needs as you accel.the first thing is to remove the fuel filter and replace it, take the old filter and blow into it, this will tell you if its restricked. the next step will be to check fuel pressure, you will need a gauge for this test, hook up gauge at valve on the injector rail, take caution wear safty glasses as fuel is under pressure and will spary out a little as you connect line for the gauge to fuel injector rail valve, you will run the engine and also step on gas pedal as you watch the pressure, i would rev the engine to around 3000rpms and hold it to see if engine tries to stall or buck when it begins to act up look at the gauge and if the pressure drops as it starts to act up then the fuelpump is bad. its not able to keep up the pressure. start there good day.

follow your positive wire from battery the starter is at the other end

it uses DEXRON III but the updated replacement for that is DEXRON VI , so use the DEXRON VI

well first off you need to start by checking the compression on all 8 cylinders!!!! to rule out internal engine failure as oppose to jumped timing. its very rare that timing chains will jump especially a double roller chain. get a compression gauge take the plugs out and get a reading on all the cylinders. you should be no more then 10-20psi difference from cylinder to cylinder. but on the chevy motors if there is a problem they usually show well on a compression test! good luck post back up the results then we can go from there.
