Well I thought I was sitting pretty this year. I sold off all my older NGVs and bought a couple Honda GXs and a used 2010 Ford F-150 (8 cylinder 5.4L) that already had an approved (YES - EPA approved) conversion (IMPCO plug&drive system - sequential injection). The system was installed about a year earlier by CLEANFUEL Solutions and Conversions (OK). My wife was happy - we were loving the newer truck and it was running almost exclusively on CNG. Well ..... until recently that is ..... when we had a couple occurances of rough running and had to switch over to gasoline (ran fine on gasoline). The vehicle started running rough and the check engine light came on. After we switched over to gasoline the check engine light would go away. Now the vehicle will not even try to run on CNG. When we try to select it we just get the red light at the top of the indicator and it beeps every 30s or so until the CNG system is deselected. Starts fine on gasoline and the tanks are full with the CNG fuel level indicating full (all CNG fuel level lights illuminated).
I thought the manual from IMPCO might help but it says to bring it in for service. Problem here is that CLEANFUEL Solutions and Conversions is not close. Found a tech service manual on the internet that talks about a diagnostic program (PC based with CAN to USB cable) but I don't see anyone out there selling the cable/software. Does anyone out there have experience with the IMPCO plug&drive sequential CNG conversion and know the most common issues?
I will probably call CLEANFUEL on Monday but I do not have the time to drive from Kansas City to Shawnee, OK probably leave it there for a while and come back for it later with a huge bill waiting for me.
Nothing makes me madder than upgrading to newer vehicles to avoid maintenance issues and then having issues.
I would really like to hear from someone that has some experience with this system. I'm guessing it could be something as simple as a fuel filter but it is hard to believe the fuel filter would get plugged in about a year. The diagnostic program seems very useful but I have no idea where to get it or how much it would cost.
Any information on this system would be greatly appreciated.
Thanks.
