Truck wont start
I have a 2003 chevy trailblazer v6 4.2 my
fuel pump is good.my fuel filter is good my
relays are good..but my truck still wont turn
on.once i put a rag with gas near the filter
goes it turns on but goes right back off once
it sucks the gas out...pleasseeee helpppp
Yes it will because your fuel pump is not pumping enough gas pressure to the injectors, you need to put a gauge on the rail and see what the pressure is. You will also need to look at the fuel pressure regulator...
The pump pressure is I believe 55 PSI
