2001 Ranger XLT Error Code
Trying to troubleshoot a couple of problems. The truck has 78,000 original miles. Here are the symptoms:
Hard start and have to depress the gas pedal a few times.
Runs good at idle and driving.
Throws Error Code P0442
Reving the engine to 3,000 rpm it runs rough
It has new plugs, plug wires, coil pack, and gas cap. Have run Seafoam through the gas. Coil pack fixed a misfire condition and the gas cap was an attempt to fix the P0442 code but did not seem to make a difference.
Looking for suggestions on how to fix the hard start, P0442 code, and the rough engine at 3,000 rpm. Guessing they might be all related to the same issue.

3,000 RPMs is right about where the neutral rev limiter is. So, that’s probably a non-issue.
P0442 hints:

As for the hard start, pop a fuel pressure tester in and see what you have when starting. That’s the first step.

Thanks. I didn't know these trucks have a rev limiter. Anyway, I just checked the fuel pressure. If I turn the key on but don't start after about a second or so the pressure climbs right up to 65lbs. Once I start, it stays steady at 65lbs. If I shut it off, the pressure drops back to 0 in about 10 seconds so it doesn't hold pressure. If I let it sit and the start it, the engine is slow to start and the pressure is about 15lbs during cranking until the engine starts. It then comes up to 65lbs right away. Is this normal operation or is there a bad fuel pressure regulator or fuel pump going bad? It has been this way for quite a while although the truck is used very little.
Thanks.
Thanks.

Thanks for the help. I am back to close this thread with the results. I pulled the bed off. I ran a 2x4 under the wheel wells and lifted it straight up and pulled the truck forward making sure everything was clear of the truck. I replaced the fuel pump assembly to resolve the fuel pressure issue. When I took the fuel filler neck loose to lift the box, the steel fuel vent line where it connects at the hose from the tank broke off. It had mostly rusted through and broke the rest of the way when moving it out of the way. I replaced the fuel filler neck assembly after replacing the fuel pump assembly. I am guessing there was a little rust through causing a EVAC leak right where the vent hose connected to the fuel filler neck assembly. Anyway, the fuel pressure now holds above 50lbs for a long period of time and the "hard to start" condition is fixed with the fuel pump assembly replacement. EVAC code P0442 has been fixed and no longer shows up with the fuel filler vent hose fix. It is working great now in all respects. Thanks again.
