Why is my fuel pump not working on my Ford Ranger?

CASE 2: If the fuel pressure gauge registered the specified fuel pressure for your vehicle’s model year: This test result lets you know that the fuel pump is working and delivering enough fuel to the fuel injectors. The reason your 3.0L Ford Ranger is not starting is due to another reason.

What’s the fuel pressure on a Ford Ranger?

The ignition coil pack feeding spark to all 6 cylinders. The PCM will still pulse (activate) all 6 fuel injectors. Fuel pressure PSI is 0 PSI at the Schrader valve test port. Engine starts, although momentarily, if you spray starting fluid into the throttle body and then crank the engine.

What causes a Ford Ranger to not start?

Can a bad fuel pressure regulator cause a fuel leak?

Fuel leaks Another symptom of an issue with the vehicle’s fuel pressure regulator is fuel leaks. If the fuel pressure regulator’s diaphragm, or any of the seals fail, fuel leaks can occur. A faulty regulator can not only leak gasoline, which is a potential safety hazard, but can also cause performance issues as well.

What kind of fuel pump does a 1999 Ford Ranger use?

In this video we have a 1999 Ford Ranger 3.0 Flex Fuel. It was towed in with the problem of no cranking. Once it was checked for codes we checked fuel, fire and compression. Given the age the fuel was checked first. The easiest way to start is by checking the fuel pressure.

What should fuel pressure be on Ford Ranger?

The easiest way to start is by checking the fuel pressure. The fuel pressure was about 5-6 psi so we knew the pump was getting power, just not producing the correct amount of pressure to allow the engine to run. Loading…

What causes a 3.0L Ford Ranger to not start?

CASE 1: If the fuel pressure gauge registered 0 PSI: This confirms that the cause of your 3.0L Ford Ranger no start problem is caused by a lack of fuel.

That may be your problem. The original symptoms did not state whether the engine turned over, but did not start. There are a couple of known issues with some years of Ford Rangers that affect starting. The crankshaft position sensor goes bad; the engine turns over, but spark and injector firing are intermittent-if at all.

Why does my Polaris Ranger have a hot start problem?

Swapped o-rings on the OEM/new regulator. Like magic, 46psi fuel pressure. For curiosity sake I tried old/new pump/regulator combinations and found out that the root cause of the low fuel pressure which resulted in the hot start problem was the OEM regulator.

What happens when a fuel pump relay goes bad?

If the fuel pump relay has an issue while the vehicle is operating it will cut off power to the fuel pump, which will cause the engine to stall. A faulty relay may allow the vehicle to be restarted a short while later, while a completely failed relay will not.

How does the fuel pump work on a Ford Ranger?
