I would've started by looking at ICP while cranking to see if it builds the 500psi it needs to fire the injectors. If oil side checks out and still no start, throw a fuel pressure gauge on it.

@@conorcuomo4283 I had 2 E99 trucks over the years and was not sure if 6/99 is the cut off date for E99 or not. Come to think of it, a lot of the E99 had odd colored interiors.

@@ricktoole9991 Absolutely! I swear by em. Stupid simple and easy to work on. Biggest mistake people make is treating the oil change interval like a regular motor. The HEUI injectors beat up the oil under hydraulic pressure non stop and it’s worth changing oil out sooner than later. Add Archoil and enjoy many more miles!
I change every 5k miles . I use Rotella T4 15W40 found everywhere. I do mix in a bottle of the Archoil additive in the gallon jug after i fill the oil filter. These take 14-16 quarts.
Oh, and whatever work you're doin on this thing, or any other modern diesel, keep a battery maintainer on it, this thing will go *absolutely haywire* below like 10.5 ish volts, and any testing you do likely won't be accurate. Keep that voltage UP at all times
Those beeps are probably airbag faults, and the airbag warning light is burned out, so you're hearing the audible backup alarm instead. See if the airbag light works, and if not, replace it, i bet the beeps stop
I believe you are correct. I had read on forums that is likely what it could be. The air bag light does not come on like in our 02’. Do you have any idea besides a failed/failing ECM as to why I cannot connect to OBD2?
@@southernrevivalautomotive probably not an ECM issue. Start with the easy stuff. If I remember correctly, the ECM shares a fuse with the fuel bowl heater, and those heaters like to short. Unplug the heater, make sure that fuse (and any other fuses) are good, and see if communication comes back. If not, on to the next thing. Get your wire back probe kit out and back probe the powers and grounds on the ECM. With a test light hooked to battery negative, test any constant power wires it has, and any ignition power wires it has, and verify by wiggling the key around a bunch that you're not losing ignition power. With that many miles the key switch could be worn out. If that checks out, and every power source it needs is present, (constant, ignition, or elsewhere,) switch your test light to battery positive and check the grounds. If those are there, you're into some real troubleshooting. If powers and grounds to the ECM are good, and it still won't communicate, there's probably a shorted 5V reference on one of the following sensors: ICP, CPS, MAP, TPS, EBPS Check the 5V reference for each with a multimeter for shorts to the ground pins on the ECM, might be able to check continuity to a chassis ground or something too, I'd try both. I bet one is shorted if everything else is fine. You can do a resistance check to the ground pins on the 5V line for all those sensors, whichever one makes the meter skyrocket is the culprit. I've seen everything from shorted MAP sensors to shorted EBP sensors bring that 5V reference circuit down to ground and kill communication. Or possibly unplug each one at a time, and see if communication comes back after each one. If you find a shorted sensor, make sure it's the sensor itself that's shorted, and not a rubbed through spot on the wire somewhere making intermittent contact with metal Hopefully that made sense and helps a little
@@robertgriffin7569 Thanks! Looked awhile for a SRW 7.3 service truck. A lot of narrow roads where I go. Been working on it and do believe the Computer is bad. Still runs strong!
@@jmaxx88shsu correct. I never not look into a 99’ with fender badges since sometimes they turn out to be an E99 7.3 . I have been busy and have not looked into it much but judging quickly off the heat tape IC pipe is assume late 99
Mine was built 6/99 and it's considered a late 99. I believe the early 99's were built in 98 and up to maybe March of 99. Not exactly sure of the cutoff month but it was pretty early in 99.
Another solid video, Just straight to the point with everything! We specifically produce LEDs for auto. Can we invite you to do a review for our product?
I couldn’t tear my eyes away from this video! The way you brought this classic car back to life is nothing short of miraculous. Superb work!
Holy bot comment
@@CarCommentator hello bot. Sure have a lot of subscribers for no view
Let’s gooo baby !! That was an epic start ! You know your 7.3 really well !!
@@SammyKurts-ku2ht yeaaaaaa buddddy. I was ready to plug 12 volts straight to the IPR 😆
1999 and early 2000 were the best run of 7.3. Beginning mid 2000, Ford switched from forged rods to cast rods and it made a huge awful difference.
@@williamconner9407 You are correct. Do you have any idea why they chose to goto the powdered rods?
@@southernrevivalautomotiveit was faster to mass produce
Did I see over 3000,000 miles? If so,TOO COOL! 🙂
closer to 400,000
👍

Good chance its a late 99. Not that someone changed them out, but Powerstroke emblems on E99 were on the fender, not the door like L99-early 03.

Nice truck minus the 5 speed.
