When accelerating engine stalls

I'm prety sure it would NOT be the fuel pump which is located in the fuel tank by the way. I say this from experience. For starters the fuel pump is electric and in 99.9999 percent of the times when an electric fuel pump gues out it's just done and doesn't work at all. I'm not sure if you have the 2.3 or 3.0 liter engine but you should check your fuel pressure in order to rule out a fuel pressure problem. You can either rent a fuel pressure tester or buy one pretty cheap. There should be a valve along the fuel rail where the connector is for the fuel pressure check. It kind of looks like a how you would fill your tire up with air. The pressure you should have for the 2.3 liter engine is between 45 - 60 PSI when running and for the 3.0 you should have 28 - 33 PSI when running and with the key to the on position and engine not running you should have between 35 & 45 PSI. Is your check engine light on? I just would hate for you to drop the fuel tank, spend the money on a new fuel pump and that not being the problem. Your best bet would be to diagnose the problem before replacing parts to save time and money. As I said I doubt very much the at pump itself is bad or it would just not work. I hope I was able to help and if you have any questions you can reply here or email me directly at and I will be happy to try and help.

My lincoln navigator has no power an shake alot

Since you mention nothing about trouble or warning lights, or about how long this has gone on, I would start with inspecting the air intake (has something been pulled up into it blocking the passage?, is the air filter completely plugged?), and then the fuel system, the fuel pump & filters, expecting the pump to be weak and near complete failure if you find no other valid reason for your vehicle to run this way.

The only other thing that doesn't trigger a warning light that I can think of is the exhaust system from the Catalytic Converter, and components behind it. If the converter is bad, the exhaust pipe behind it will rarely get hot as the converter is plugged.

You can eliminate the fuel pump issue by testing with a pressure tester. A heat sensor or just checking out the exhaust up close without getting burned will tell you if it's the exhaust system.

Beyond that, you'll need to start testing sensors.
Good luck !

Van turn off

Check for spark in order to see if the engine's ignition system is working.
Add starting fluid to the intake to see if it starts for a few seconds.
If the car does start, then it's a fuel delivery problem such as a fuel pump or a computer that doesn't allow fuel injectors to pulse.

If it doesn't start, then the spark is likely not being delivered to the spark plugs.
One can double check this by using a spark tester for the spark plug boot removed from the spark plug and grounded to the chassis.

Hyundai 2003 Santa Fe 2.7V6 - engine turns over fine, doesn't seem to be getting fuel immediately. Eventually it starts after 5 or 6 seconds of turning over. Suspect fuel filter or fuel pump?

Initially I would agree fuel pressure had dropped off after shut down. This fuel filter is a sock screen attached to the fuel inlet tube of the fuel pump and is located inside the fuel tank with the fuel pump. This screen is rarely the cause. You'll need a fuel pump pressure gauge to verify the low fuel pressure at start up. Caution, sometimes this low pressure isn't a faulty pump, sometimes it's a poor wiring connection to the pump motor. An analog amp meter can verify if there is fluctuation/ing current flow to the fuel pump. A fluctuating current flow could mean poor connections, or could mean the pump has/is gone/going bad.
