Hi all, firstly I’m not a mechanic so forgive my ignorance here. I’ve just bought a 2014 2.2 ranger and it has an issue local garage seem unable to sort. They’ve had it 5 weeks and decided it was the fuel regulator that needed replacing and appears this was causing some issues but the symptoms are still present. I’ve been told to drive it and it will clear but doesn’t seem to be improving. There is hesitation while accelerating especially at around 1900 rpm. Sometimes lower. Is it likely to clear or does it need further investigation?

 

Welcome to the forum

Unfortunately we are in North America and could never get your T6 Rangers here, or even import them
Out Rangers were smaller and 1983 thru 2012, and different engines

Try Australian Ranger forums
They got the T6 Rangers down under, lol

 

So I might be having a similar issue, I have a 2001 Ranger with the 3.0 and it has 235k miles on it. I bought it from a family member who used it as a work truck. It has had a misfire ever since I got it, I have replaced all of the fuel injectors, spark plugs are new, along with new wires. When I am driving, it will start rough at times, and if I don't give it a lot of throttle, it runs fine. Anything over 1/4 throttle, it starts misfiring really bad, and just runs poorly. If I just stomp on the gas pedal, it falls on its face, makes no power and reeks of raw fuel. I am debating if it is a bad O2 sensor, which I don't think so because of the no CEL. I thought today that it could be a possible fuel regulator issue? I believe it is the factory regulator, and with that many miles, I would expect it to be having an issue. Any help would be great, Thanks!

Welcome to the forum

O2 sensors are the only sensors that wear out, 12 years or 100k miles and replace them, they don't set a code just cost you money in lower MPG, by the time they set a code you could have bought 10 new ones

Do a compression test to take that off the table, 3.0l's burn valves, so if that's the issue then spark plugs and injectors will never help, best to find out before spending more money on the wring stuff, lol

Clean the MAF sensor, do NOT replace it
Replace fuel filter, $15, if it hasn't been replaced in the last 5 years, should be done every 5 to 8 years

There is a fuel pressure test port on the engine, looks like a tires air pressure valve, 2001 should run 55-65psi pressure at idle, raise RPMs to approx. 2,000 and hold, pressure should stay the same, of its slowly dropping then yes a pump or fuel pressure regulator issue, but BOTH are in the gas tank in 1998-2011 Rangers, you would just replace the whole assembly if pressure was running under 25psi
