Replying to: tybee (Jan 22, 2007 5:22 pm) Before replacing the fuel pump, replace the gas filter. Located on the frame on the driver's side, kinda located under the driver's door area. Filter cost around $10.00, it takes a special tool that costs less than ten dollars for the press on connections. They are spring loaded connections. We had the same problem.. and it was the filter. Found out, what we should have known.. buying cheap gas at cheap stations is a big no, "NO". All your Mobile, Exxon, British Petroleum stations have refineries. All your places like Pilot, El Cheapo and discount gas stations buy from the lowest bidder. They are getting dirty gas, probably sold by the refineries when they get down to the bottom and have to clean out their tanks..so they sell this crap to the guys who deliver to these cheap gas stations. We checked our filter..it was filthy, shook ours out in a cup size glass and got a quarter inch of dirt out of it. My husband was ticked. And, if you keep buying this crappy gas, it's only going to end up costing another bill getting your injectors clean. We thought about it and we had a friend who used to "always" buy from the cheap o places.. he got stuck out on the lake and looked in his tank and all he saw was dirt!! Take care, and Happy motoring... we love our F-150, but it wants to be fed better gas! Our last F150 had 298,000 miles on it and we sold it, buyer is still running it a year later and loves it! Home maintenance!!

#45 of 92 Ignition control module by 98autobahn Oct 03, 2007 (7:51 am)
Maybe someones had this problem before, my dad just bought a 96 f-150 (straight six), on his way to work it shut off, we figured the ICM, bought one put it in , started right up, next day it did the same, put another ICM in, started up 30 min. later did the same. Anyone have an idea what would be causing the ignition control module to go every half hour? Any help would appreciated. Thanks

#48 of 92 6.8L V10 computer problems??? by cable_guyxxx Jan 31, 2008 (10:10 am)
Hi,    I have a 2000 f-250 6.8L V10 4x4,Automatic... One day last summer right after refueling I was sitting at a red light and my engine just died, I went to crank it over in neutral, and it started right up. When I put it back into drive the whole truck jumped forward about a foot and then killed the motor again. repeated the process a few times and finally after reving engine to about 3000 rpm's and slamming it into gear it took off but was real sluggish and non-responsive... Shortly after that the check engine light came on..        I took it to a transmission shop they thought it was a pump inside the transmission that was warped, but quickly figured out that it was not. So they unplugged the transmission from the computer to test on their diagnostics machine, it shifted through all gears just fine. And apparently with the computer unplugged it will drive like an old school tranny.. just hi and low gears (2 and 3) no 1st or overdrive but you have to manually shift.. so they told me it was most likely a computer issue and to take it to the dealer. So I took it to ford and after the $543.40 diagnosis fee and a week of headaches they supposedly found nothing wrong with any part of the computer or electrical system besides a misfire on cylinder 9.( Which I fixed) And then they told me they thought it was the transmission!!..If anyone knows what might be wrong please help!!! Having to manually shift with no overdrive I'm getting roughly 5 miles to the gallon on the highway and I'm working out of state!!!!

Replying to: tyson7 (Jan 03, 2008 6:12 pm) P0300 is a tuffy when it is intermit ant. The PCM detects random misfires but doesn't know why. This usually means something that the PCM doesn't know about; fuel pressure, power to the coils, something like that. I would first check the fuel pressure and test drive it until the misfires occur again, and see if there is a drop in pressure during the test. Unfortunately, you have to start ruling things out, or keep changing parts.
