2001 Blazer 4.3 Fuel Pressure Drop at Fuel Filter
Working on a friends car, wont start, 60psi of fuel pressure when pump is running (key on for 2 seconds or relay bypass) as soon as the pump stop running pressure drops to 0 and does not hold.
Truck wont start. I want to find the cheapest route possible.
Checked pressure at fuel filter in the middle of the truck and pressure doesnt hold there either which makes me believe leak is behind filter at tank.
I've done some reading and read that aftermarket setups are bad. is this true?
what do i need exactly. I read it is the check valve. is that part of the sending unit??? or is it inside the actual pump itself.
