Good day.

so the truck quit on me. It wouldn’t start. Replaced the starter and battery, I got it to fire.
the problem after getting it to start is it’s now sluggish. Barely any power.

1st gear is not bad, but on 2nd it will jerk and sounds like a backfire.
it can barely make it to 20 mph.

Dec 2018 when the fuel pump failed and I replaced it and was running good until recently.
new plugs and fuel filter about a week ago.

Distro timing is around 8

drove it with exhaust disconnected thinking it might be plugged; same issue

Cleaned the air box and maf


any ideas?


thanks
