IT is happengin every week or two. 14 people found this helpful. I have a 1998 Dodge Ram 1500 with a 5.2 and I bought it after it had been sitting 8 years and it ran strong for a day or two then on my way home it stared losing power and cutting out and then died.

When did my Dodge Ram 1500 start sounding like a Deisel?

My 1500 started sounding like a deisel about 5 years ago. I was told it would be several thousand to fix it, but it really gave me no problems. Once in awhile at 70 or 75mph it would start surging. But that was rare and no big deal. I think I’m now at a point where I need to sell or repair.

How can I check if my fuel pump is working?

Before you check your fuel pump, find the fuse that corresponds to the pump and pull it out to see if it is broken or burned. If it looks fine, check the voltage at the pump itself to make sure the charge that’s leaving the fuse gets to the pump. If this looks alright, then perform a fuel pressure test.

Where is the test point for a fuel pump?

Hook the pressure gauge to the fuel pump test fitting. Locate your fuel pump test point, which is usually near the fuel injectors, and locate the point at which the pump hooks up with the filter injector rail. There should be a separation joint or a test port, where the pressure gauge attaches.

What should I do if my fuel pump is not working?

Perform a voltage drop test like described in the previous section to make sure the fuel pump isn’t the problem. If the fuse and the fuel pump tests come back negative, take a look at the filter. If too much residue built up in the filter, it can limit the performance of the fuel pump. Finally, you can check the fuel pressure.

How much does it cost to test fuel pump?

If the fuse and the fuel pump tests come back negative, take a look at the filter. If too much residue built up in the filter, it can limit the performance of the fuel pump. Finally, you can check the fuel pressure. This will require a fuel pressure meter, which normally costs $20-$30.

How do you test a fuel pump fuse?

Check for a broken or ‘burned’ look. If you can’t see anything wrong with the fuse, but you want to be sure, you can use your multimeter. Set the meter to the resistance setting (usually shown with a Ω symbol) and put the two leads together first. Now, put a test lead on each end of the fuse.

Can a bad fuel pressure sensor cause a car to stall?

But even if it is the first time you stalled, it could still be due to a bad fuel pressure sensor. With a bad fuel pressure sensor, the engine will not receive the proper amount of fuel for its internal combustion process. Because of this, the engine won’t release the right amount of energy for the rest of the car’s components to function properly.

What does it mean when O2 sensor stops working?

Hence, This means the sensor is operating properly. If the (O2) sensor only produces a low or high voltage signal. So, either you have an engine performance issue or the (O2) sensor stopped working. Finally, To verify sensor operation, conduct the next two tests.

Why is the fuel pump in the fuel tank?

It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do. While being in the fuel tank makes the pump more reliable, it also makes it a lot more difficult to get to. The good news is that fuel pumps are inexpensive.

What happens when there is no fuel in the fuel pump?

This also verifies that the engine has no fuel pressure. Electric fuel pumps on electronically controlled fuel injection systems need to produce enough “high” pressure to allow the injectors to produce a sufficient spray of atomized fuel into the intake path (or into the combustion chamber in a direct-injection system).

Why is my fuel pump not working properly?

When you pull over and check the fuel pressure, the engine is idling and under no load so the injector pulse width is minimal = great restriction on the pump. Under those conditions, it is easy for the pump to maintain pressure.

What are the symptoms of a bad fuel pump?

With that in mind, most of the symptoms of a bad fuel pump revolve around the vehicle stalling out or not running at all. In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail (s).

How can I tell if my Dodge fuel pump is bad?

Start by verifying that the Dodge has a fuel problem. Also, a fuel problem does not always mean that the fuel pump in a Dodge is bad. Locate the Schraeder valve on the fuel rail. Take the cap off and install a fuel-pressure tester. Turn the key on and check the pressure. It should be 49 psi.
