SOURCE: wont start no fuel pressure
this vehicle needs 60 lbs of fuel pressure to make the popit type fuel injectors to open you need to check with pressure gauge
SOURCE: low fuel pressure 95 volvo 940 turbo
fuel pump check valve doesn't cause pressure loss, just hard starting cold, the check valve is part of the fuel pump, so to replace the valve u must replace the pump. do not use anything but the orig style pump, here is the part number from THE OE PUMP MAKER AT www.rockauto.com
DELPHI Part # FE0071 PRICE $124.99
SOURCE: No fuel pressure at shrader valve on fuel rail.
defective fuel pump almost for sure, if the car has over 100,000 miles it is certain the pump is defective, the pump is located inside the fuel tank.
SOURCE: I have no fuel pressure
There is a safety cutoff switch called an Inertia switch. It can be located in the trunk area or behind one of the front kick panels. This switch can sometimes trip when a door or trunklid is closed. There is a reset button on it and you just push and hold the button for a second or two and it is reset.
When you turn your key to the Run position you should hear the fuel pump run briefly to pressure up the system. It will only run a few seconds as that is all it needs for the pressure. There is also a Relay in one of the Black boxes and one is for the fuel pump. This Relay also needs the Inertia switch to work before the power gets to the pump. Finally you may find a fuse for the pump in the fuseblock under the dash. Your Owners Manual should describe each location.,
SOURCE: My 1995 Volvo 850 will not start. I think it is
another way to test it
unplug any fuel line you can locate tell a friend to start key one turn only if the line squirts fuel then pump is working and it might need regulator
if not then pump is gone
Testimonial: "That was good. Since I necer hear the pump I am shure that when I open up a line I will have proven out the bad pump. Thank You."
