Changed fuel pump still same thing. Getting plenty of fuel it just won't start and if it does start it only idles for up to 10 seconds. Any acceleration and it sputters and makes the whole vehicle shake. Checking for spark at each plug now. Any help much needed.

Not sure if you have been driving yours or not. Mine died outside the driveway and would start and die or no start at all. Ended up the coil wire was rotted under the plastic sheath. Try it while its dark to see if there is any spark jumping.
#485 of 496 blazer stalls,spits and sputters

HI, i have a 1998 chevrolet blazer 4.3L vortec V6. It was running fine at first. But it started the run very rough and shakes like crazy. the temperature gauge doesnt work even after installing a new temperature sensor. it does this everyday. sometimes on very short drives like at lunch it will drive fine on the way to the store and then drive like crap on the way back. the temp gauge moves from cold to hot and back to cold when ever it is starting the spit and sputter. it stalls at traffic lights and is a pain to get it started again.. i have to pump the accelerator to get it started when ever it stalls. when ever the spitting and sputtering problems occur when im driving it stops running like crap when i floor it. but stills runs like shit after. i dont have much $$$ and with a baby on the way i need to get this fixed. help very much needed. thank you.

Well, I fixed it...It turned out to be the fuel pump. I replaced it and it fired right up with no issues. Lesson learned...fuel does not necessarily mean that the fuel pump is good.

Remember: Dead or Dying Fuel Pump Will Not Give A Code.
90% of the time, the stalling issues will end up being a fuel pump.
The fuel pump is like any other electrical motor. Take the starter for example.
If you find the starter is burnt out, you can some times strike it with a small hammer or anything else with some weight, and you might get it to start again.
Now why none of the car companies will put a sensor on the fuel pump, is beyond me. It would actually be a simple thing to do and would stop alot of the heartache.
Something like this:
Key is put into ignition mode-No gas pressure? Send Error Code.
Key is put into ignition mode-No electric signal passing though? Error Code.
I can do this with simple programming to a microcontroller, yet none of the billion dollar car companies can add this feature into the system?
Now one other feature that could be very simple to intergrate into any vehicles system, The Code Read-Out onto a 0.50 cent LCD panel possibly on the fuse box, instead of having to take your broke down vehicle to any shop or car parts store to have it scanned.
Why don't they?
Because the car companies want you to pay top dollar for all of the repairs, the diagnostics and possibly get you back into the dealership to purchase a new vehicle.
FUEL PUMP PEOPLE, And prepare to pay out atleast $600.00 for a new one isf you vehicle is a 1998 or newer.
