New to forum and some questions, truck died last night.
I just bought a 99 F250 XLT 7.3L crew cab 2wd, 270k miles It's very much the same as my dad's 99 but his is the long bed with the half doors. He is the reason I bought mine as his has served him very well for nearly 300k miles. My 90 Dodge Ram (360, 1 ton) was totaled while parked by a neighbor (bad story, don't ask).
So my new ride has a Banks Stinger package which includes the big head, stainless exhaust (no cat, is that normal for a TX truck?) ottominder and trans module. The truck starts easy and pulls strong, but takes a while to spool up. Driving home last night I was about 1/8 tank (still 1st tank from purchase, dealer filled it when I bought it) and I noticed there was a miss or stutter to the power maintaining speed at around 70. This became little and then no power over the next mile and soon I could not hold an idle. I checked the oil, all looks good, nice and clean, recent Ford oil change at the dealer. I was close to Dad's place so I called him for advice, he headed my way. While waiting for him, about 10 min later I tried to start it again, it fired up and would rev so I pointed it towards a gas station I spotted on the other side of the freeway. I filled it up and he arrived. He opened the water separator drain on the fuel filter and dumped some fuel. It was night so I really did not get a good look at the stuff but this seemed to clear the problem. The truck ran great on the ~30 mile drive home. Once I got off the interstate, I noticed the truck seems to rev up much more quickly than before, there is a lot more power off the line. The turbo spools up more quickly.
I'm a diesel NEWB. With that out of the way, I'm mechanically inclined, I build vintage triumph motors so I know how to turn a wrench. The truck looks well maintained and is super clean. What else should I look for or be concerned about? My assumption was that there's crap in the fuel and getting lower than 1/4 tank may not be advisable until I have the tank drained at some point.
I'm open to advice and speculation, and, I'm sure, an education. I'd like to know what is where on the motor and what I should be expecting to do outside of oil changes on this truck. gratuitous pic:
