1999 2door blazer installed new fuel pump 60psi when tested won't start dump gas in intake starts and shuts off ??????

Sounds like your injectors aren't opening if it holds that pressure. Get a "noid light" at parts store that fits your injector harness connection (just a few bucks). Just pull connector off injector and plug in noid light. When you crank engine, the light should blink rapidly. Try all of them, or at least one on each bank (side).
If light doesn't blink, then check your injector electrical circuit. Power to them is fed through your ignition switch, and the ecm grounds that particular injector at proper time to make injector work.

How many fuel filters are on a 99 blazer?

There should be only one unless someone has modified anything. It should be located on the frame rail by the drivers door. I assume it is a base model with a 4.3 L engine. There is however a strainer located in the fuel tank attached to the fuel pump. Hope that helps.

I have a 99 chev blazer and it falls on it's face and then the next minuite it falls on it's face. Won't hardly run. Someone told me it's probably the fuel pump does the fuel pump have a fuse?

The fuse would not allow the fuel pump to work,then not work,replace the fuel filter first,if this does no good,have the fuel pressure checked.If this was helpful,please rate,thank you.

1991 chevy s10 blazer

Check the fuse under the dash. Did you replace the inline fuel filter? If not, you could loosen the line going into the filter then turn the key to the on position. The pump should run for about 2 seconds then the relay should kick off. Turn off the key for approx. 5 seconds then cycle key back on and the pump should cycle again. If you get a 2 second burst of fuel each time then the pump is cycling. Install a new fuel filter and check the grounded wire by the tank. Hope this helps. :)
