Engine Mechanical problem
1995 GMC Sonoma 6 cyl Two Wheel Drive Automatic 123000 miles

My truck cranks but wont start. Fuel pump turns on, sounds healthy, sometimes I try it a few times over the course of 5-10 minutes and it starts roughly and chugs like its running outta gas and then stalls. Then sometimes it cranks right over and fires up and runs fine. When im driving I put it to the floor and it kicks down like its supposed to but then skips and hesitates. But if I ease the pedal down slow. It does somewhat ok. Also. There is a lack of lowend power.

Do you
have the same problem?

Fuel pump comes up and I have replaced fuel filter also. I have spark but engine still won't start. Could this be timing belt if I am getting spark or maybe a module?

You got spark -check the fuel pressure if its within specs and also check if the injectors are pulsing-start here
