Re: Fuel pressure question
i thought on TBI the fuel pump only pumped what it needed, and up'd its pumping on demand, as dictated by the ECM.
I imagine that too much back pressure in the system might fry your pump?
are you sure your gage is connected correctly? not to insult your skill of course, but if there was not pressure, then no fuel would be flowing ? if your gage was correct and reading no fuel pressure then your injectors would have no force behind the injection and the fuel would dribble out instead of spray.
i vote that if you donthave an huge lack of power you dont mess with it, ....and if you do, carry a spare fuel pump just in case
can you describe your setup, what TBI on what motor and so on.
