Pickup truck listed above is a 5.9 liter. Sluggish no power on hills acts like it's starving for fuel. Idles fine just no power.

I have not had it on a machine.I was just trying to get a second opinion. Could it just it be a clogged filter?

You don't have to use a machine to check for some codes. You turn the key, just till the dash lights come on. Cycle the on--off, on--off, on, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

As far as the fuel filter, that is why I asked, how long since a tune-up? Use a gauge and check fuel pressure.

I put a scanner on it reads no codes. But the dash light for check engine flashes 10 times.

Good morning,

You may mean 11 times. If it is, that means the system has passed and no codes.

As far as no power, there are a couple of possibilities.

1. Clogged catalytic converter which is common. You need to release the exhaust pipes from the exhaust manifold and drive it and see if power returns.

2. Low fuel pressure. This could be from a weak fuel pump or a clogged fuel filter. A fuel pressure test will verify.

3. In rare cases, a locked up torque converter can cause this as well.
