I would suggest measuring the fuel pressure at the fuel rail under the hood. As i recall, the pressure while running will be around 40 psi.

SOURCE: F250 Diesel Super Duty started jerking while

It may have run out of fuel when the filter was replaced, you may need to use some starting fluid for diesel to getting going and when it starts just rev engine for a few minutes to bleed any air out, also the fault may be related you would have to scan it to see what the fault is , i would start with these things first. hope this helps, good luck.

SOURCE: While truck was running I disconnected a fuel

Removing the relay would not releive the fuel pressure. Arc across the fuel relay terminals and jump start the fuel pump. Also check to make sure the fuel filter is properly installed.

The built in pressure relief valve in the fuel pump may be defective in the fuel tank, this causes fuel pressure to bleed off and causes hard starting..

1992 F350-7.3 4wheel drive is hard to start after changing fuel filter and fuel pump. Why is it hard to start?


indicates fuel leak back and fuel pressure drop
check filter installation for seal not sitting properly, loose fuel line fitting , pump installed correctly (flow wise ), filter installed correctly (flow wise)
air getting in to fuel lines
the thing you are looking for is indicated by the initial hard start but when started runs ok ( good fuel to the engine eventually) and then by the fact that if the engine is allowed to sit for a long period the problem returns meaning that the fuel pressure is not being held
could even be a problem fuel pressure regulator allowing the fuel to bypass ( no pressure =hard starting) then gets enough pressure to run ok but allows that pressure to drain off over time

I can not get my car to start i think i have a fuel problem


Have you sprayed brake cleaner in the intake to see if it will start, if it does then check the fuel pump fuses and the fuel relay, before changing the fuel pump make sure there is power to the fuel pump (test light works fine) always change the fuel filter when putting in a new fuel pump.

1992 ford f150 duel tank problem, hard to start


The tanks have to be removed in order to change the fuel float sensors.

The hard to start issue could be related to a fuel filter that is full of sediment. The fuel filter could be in the engine compartment before the intake to the engine, but it is more likely an inline filter after the fuel pump on the frame rail. Change the filter and see if that help.
