As title says, my 94 blazer has spark, and has a working fuel pump.

I cant seem to get it started though. any ideas?

 

Just because the fuel pump is running doesn't mean it's working.

Have you tested the fuel pressure at the schrader valve?

 

i know its getting fuel, just i dont have a tester to check how much

 

have you tried pouring a little fuel down the throttle body, and then starting it? if it fires right up, and runs fine, try shutting off your truck for 15 seconds and then try restarting it, WITHOUT POURING FUEL DOWN THE TB. if it doesn't start this time, then your pump is probably going.
