NEED HELP! Car tied...had it towed
This is my first post here and its not a good one! I just bought a 99 blazer 4 door with 90,000 miles. I was driving about 30 miles today when the check engine light was on (normal occurance, was usually just tramission 1-2 rough). I made it about 20 miles and it just started dieing...i was in 5th...then wouldnt speed up to 4th...then 3rd...started pulling over to an exit on the express way and it just died. I tried to turn it back over and nothing...it won't turn over. It didnt look like it had overheated (intake manifold gasket about 1k miles ago) temp gauge looked fine, oil pressure looked fine...it just died. Any ideas what it could be? There was still oil (it was HOT!..but there was oil!) Need help ASAP please!!

To clarify a bit, I don't know what the fuel pump "sounds like" but I hear it try to crank and crank and nothing. The CEL light flashed from being constant and just proceeded to die. The tranny was fine aside from the occasional hard shift from 1-2 gear. After it died it would just crank and crank and crank and no start...

The fuel pump has a buzzing sound to it, if you turn the key to the on position go to the rear of your blazer and lay under the rear and listen for a buzzing sound from the gas tank if there is no sound then I would put money on it being your fuel pump!!

Well, when i was trying to crank it all I heard was the accessory belt squeeling trying to turn over, would the blazer still turn over if the tranny went??

Yes the motor would still turn over if the tranni was bad if your truck just died and you don't hear a buzzing coming from the back then I would point at the fuel pump that went out!!!

You've been a great help so far gr81! Any cheap sources for a fuel pump?!...cheapest I can find is 200...if thats the issue...have you ever heard of the CEL light flashing right before dieing???...how much labor is involved in replacing the fuel pump (shop labor)?

Well as far as replacing the fuel pump and a cheap place to get one there isn't our fuel pumps are some of the most expensive but to replace it isn't hard but make sure you can't hear anything in the gas tank by laying under it listening for that buzz I told you about with the key turned to the on position, if there is no buzz sound or you don't hear anything in the gas tank then replace the pump.
To replace it get a tranni jack and place it under the gas tank and then jack it up and loosen the tank straps and drop it down fuel pump will be on top and it is in with a few screws take the hoses off and the screws out then take out the old pump and drop in a new one!!!
Oh and by the way no problem on helping its what were here for!!!

Slow down there!
You cannot condemn the fuel pump right off the bat like that without proper testing. Its a good way to throw $200+ at a problem, possibly not correcting it.
You should atleast test the fuel pressure, which should be at 55-60psi for proper starting of the engine. Locate the fuel pressure test port (behind the throttle body - little black cap a bit bigger than a tire valve stem cap) and push in on the valve (be careful). If fuel sprays out, then you atleast have some pressure, but you still don't know how much pressure is there. Most autoparts stores will rent a fuel pressure tester, but if not, they are only like $20 to buy one.
A flashing CEL means a potentially engine damaging misfire has been detected. Since the CEL has been on, it has been telling you that there is a problem. To go anywhere with diagnosis, the codes should be read and posted here.
