I may have posted this in wrong location..
I am at witts end...2001 Tahoe 5.3 crank no start...I've replaced fuel pump three times in last week...It has a delpi pump with new filter ....replaced crank sensor repalces fuel regulator....I have injector pulse...I have spark at the plugs ....ive tried eliminating nuetral safety switch by moving thru the gears and trying in neutral to start...by way of cranking the motor sounds as if it has good compression..and it will run on starting fluid. I know I'm missing something that I've tried...I've also checked my grounds and ran a few temp grounds to be certain with new battery.....ANYONE HAVE ANY SUGGESTIONS
