i have a 1996 blazer quit running , got fire and feul pump works whats wrong??

If there is fire at plug,and fuel pressure at fuel rail,may be timing issue.

The timing hasn't changed

Are you sure there is fuel getting to fuel rail?Just cause you hear pump ,doe,s not mean it,s pumping.

Well I checked the pressure relief valve and I got fuel squirting out, I know it'll run cause I sprayed gas and it fired right up, so the fuel is not getting to the throttle body

If you are getting fuel to the rail,and truck cranks up win you spray gas in,youve, got fire,it will have to be the pressure regulator bad,or check the injector,s,check truck fuse,s should be injector fuse.

Where's the pressure regulator on the 1996 blazer??

OK, now fuel pumps OK, ran for 2 days now I ordered a fuel pressure regulator, now my question is when I pull that intake off to replace the regulator do I need to replace the rubber gasket???
