What have you replaced or done to the vehicle so far? For the fuel pressure to be at zero you may have a bad fuel pump, broken fuel line, bad check valve, faulty fuel pressure regulator, bad relay, blown fuse, broken wiring, or faulty plug/connector.

My 1981 C70 was ran out of fuel and now wont start low to zero fuel pressure


Some late model vehicles have a fuel pump cutoff safety switch that kills the pump if something causes the fuel pressure to drop to zero (like a broken fuel line). In such cases the safety switch has to be defeated if you run the vehicle out of gas. Check with a dealer or a mechanic familiar with this issue for information.

2007 chev colorado fuel pump


First I would check for a stopped up fuel filter or just replace the filter. When you remove the fuel filter, look at the fuel that comes out and see if there are beads of water in the fuel. If the filter is ok and no water is in the fuel, you need to check the fuel pressure. Some Auto Parts stores will lend you a fuel pressure test kit. Throttle Body pressure is around 18 to 24 psi. For port tuned injection 40.5 psi to46 psi. Depending on the type of fuel injection you have, if this pressure is there, turn the ignition switch off and see if the pressure remains at the pressure you had with the ignition switch on. The pressure may slightly drop lower and then slowly drop off 3 to 5 psi after 3 or 4 Minutes but not back to zero or near zero in a short period of time. If the pressure is 10 or 15 psi lower then stated above, you may have a fuel pump check valve in the fuel tank that has stuck in the open position, or the fuel pressure regulator has gone bad and leaking. If the fuel pressure regulator has gone bad usually the fuel mileage has dropped off, and black smoke would have been coming out the tail pipe, the engine would have been idling rough.

Fuel problem


If you know there is fuel in the tank, and the pump is running, and you have zero fuel pressure at the rail, either something is restricting the fuel flow from the pump to the rail, or the pressure regulator has failed and it is allowing all of the fuel to return to the tank.

My 2000 S10 with the 4.3l vortec is hard to start. I connected a pressure gauge to the schrader valve and the fuel pump builds 10psi when I turn on the key. If I cycle the key several times it will slowly...


Key on engine off pressure on your truck should be 60-66lbs. A fuel pump replacement is definitely in order, bad thing is it is a whole assembly.

Fuel pressure drops immediately to zero when engine is shut off.


I am not really familiar with the setup there but I'd be looking for a second relay to kick the pump on when cranking.

Fuel starvation


Check the fuel pump, the fuel filter, and the return lines to the fuel tank. Any one of these things could cause a zero pressure condition in the fuel system.
