Fule Pumps Help!
My last post was related to 2 trouble codes and a high idle. Problem solved. The EGR Valve gasket some how got bent up during installation. I cleared the codes and it passed smog with flying colors. Now on to my current problem.
I went 4 wheeling for the first time in this truck this past weekend. Not to bad of conditions, just a little mud. The truck being stock except for 31 inch tires did great. On my way home a few hours away, the truck began to stumble and die like it was running out of fuel. Not the case. At the same time my check engine light came on rapidly. I drove like this down the highway a few miles, and it dies on me, and didn't want to restart for a couple hours. I got it started, and continued on home. It didn't make it. I managed to get it to a friends house to figure out what is wrong. I checked my codes again and they are as follows: The same 2 before 32 and 67. I think they were there from before and I forgot to clear them.
Code 53: TP circuit above maximum voltage.
Code 54: ACT Sensor circuit open.
Code 64: ACT sensor grounded or input reads 254 degrees F.
I replaced the ACT Sensor (Air Charge Temperature) and it started to run good. I decided to head home and it completely dies on me and doesn't want to restart at all. I finally gave in and had it towed home. At home I discovered a big problem. No check engine light coming on at all when KOEO. And both fuel pumps remain ON with the key off. I guess the reason it won't start is it's getting way to much fuel. I don't know if it is computer related, or the fuel pump relay. The relay is only $11 at Ford. But the computer is about $120. Any help will be greatly appreciated. Thank You.
