Scotty my 2011 Ford Ranger 4.0L V6 loses power while driving and will pop, sputter and spit. No response to accelerator. No cel or codes at all. The truck would "bog down" losing power while driving. The fuel filter was removed, inspected and replaced. It had some water and trash in it even though it only had 10K on the filter. The fuel tank was removed to see if fuel had water but none was found. The sock filter was filthy but can't be replaced without buying a fuel pump ($260). The sock was cleaned and the fuel pump re installed and fuel tank assembled to the vehicle. The truck did the same losing power, popping and when accelerated no power. I then tried a fuel pressure test. When the vehicle was turned on no pressure was noted. After a short time the pressure rose to 30 psi. The truck was cranked and the pressure rose to 50 psi and then to 65 psi. The needle would fluctuate erratically and rapidly. I decided the problem was fuel related and as a result I replaced the fuel pump with no improvement. I inspected and cleaned the MAS AF Sensor, Throttle Body and EGR Valve. Still no improvement. Approximately 8 months earlier I had replaced the spark plugs with no problems. Approximately 2 weeks prior to the problems the battery was slightly smoking and I replaced it again with no problems until about two weeks later when all this began ($95). I took it to the shop where it was scanned and I was told the voltage regulator was bad and over charging. The alternator was replaced ($235). The mechanic also suggested that as a result the voltage may have damaged the PCM. Since the vehicle continued with the same problems I replaced the PCM ($300). I was told it would be "plug n play" but that was not true. Now the truck would not start so the keys had to be programmed at the "STEALERSHIP" that is the only place it can be done at a cost of $105. The truck still would not run right. So I returned it to the shop since the STEALERSHIP was not interested in helping. The exhaust was disconnected and the truck seemed to run like it was supposed to. The catalytic converters were blocked. At a cost of $500 they were replaced and the truck now has power but will still pop and lose power then immediately catch back up and run continuing this way. I am the proud owner of a pos Ford Ranger 5000 lb. driveway ornament. With no solution in sight and still no cel or other codes. If I fix it I will definitely jack it up and run a new Chevrolet, GMC or Dodge under it but will definitely never own another Ford. Can you help?
PS Scotty is the fuel pressure regulator built into the fuel pump and if not where is it located on a 2011 Ford Ranger 4.0L V6 engine
Thanks so much!!! Can you explain how to check and clean fuel lines, fuel rails and injectors. Being at my residence my resources are limited but I do have a small air compressor. Best Regards Charlie
If there are no codes stick to looking at the fuel system - with all that garbage in the fuel system there is a very good chance that the injectors, fuel rail or fuel pressure regulator is also gummed up so keep at it - also try another mechanic who is more interested in finding the problem and fixing it rather than guessing - pay for results not guess work
