Have a engine running problem and it is getting worse
Hi all, I could use some help...
My mods are below and overall the truck has been great.
A week plus ago, I was driving th EX and shortly after I got out of the neighborhood, the truck power fell flat on its face. I shut it off and pulled over. I turned the key off and then back on and let the GP wait to start light to go out. Re-started and drove away with no other hiccups.
My son drives it a few days later and the same occurs and his response was the same, 2 days in a row.
We usually just start the truck as our weather has always been warm. It is cooling down now. My son drove it again and I had him start the truck early, wait for the GP light to go out and let the truck idle in the driveway for 10 - 15 minutes before leaving to school. He had no problems.
I went to start it Thursday and it didn't want to start off first try and the CEL (or SES, whichever it is) came on. I read the codes and had 1393, 1391 and 1211 in that order if that matters. The 1393 and 1 is for GPC low input Bank 1 and 2 with 1211 being Injector Control Pressure higher/lower. I tried to start again and it fired right up and then had no problems. I cleared the codes after jotting them down.
Now is where it is worse. I went to drive off yesterday. I did not let the truck idle as it was in the upper 60's. I got to the end of the street and the power fell off and I kept it running until it shut off. Turned the ignition off and on, let the GP wait to start to go off and when cranking, it was like out of fuel and took a while to eventually fire off and was sluggish for a while. I thought that may have been all and able to drive off - BUT NOT THE CASE. It happened 2 more times before I could get it around the block and back in the driveway. Everytime was like running out of fuel. I have almost a half tank.
I did replace my fuel filter some 5 to 6 weeks ago with a Autozone brand filter.
Are they prone to have problems?
Could it be something else?
I could really use some help figuring this out.
I have had some other codes occur in the past while driving that did not affect anything. I would clear them and think it was because of the programmer and tune. It seems like my fuel economy is not that great either, as pulling an open trailer to KY a few weeks ago - I got 15MPG going driving 60 to 70 MPG and 12MPG coming back driving 70 to 78 MPH. The trailer was simple and had a 3650# car on it with nothing else except inside the EX.
Any and all help is greatly appreciated. I am heading out to pull the fuel filter out and see what the fuel level is in it. What should I see?
Thanks in advance,
