Driving '03 Excursion 7.3 with 82K down interstate. ENGINE DIES, all lights are on, coast to side of road, no restart. Just cranks like it should. Theft light is ON, flashing rapidly. Tried to address it as a PATS issue with no luck. Tow home.
Replace a fuse that blew a few times (#22 or #30) when trying to restart. Unplugged fuel filter heater/wastegate noid. No more theft light after new fuses or some tinkering, no sure what changed that. Still no start.
Tried two known working CPS. Pulled driver side valve cover to check harness and previous owner installed clips already. Glow plugs tested fine on passenger side when I have VC off. All fuses good, swapped around some relays in fuse box for fun.
Bought and ran AE from laptop. Buzz test passed (though half injectors were a weaker buzz (2,4,3,5).
Couldn't get any fuel pressure to read out on AE while KOEO (what should I read?)
Changed IDM with a known working unit from my 2002.
Wait to start comes on as it should. I hear the fuel pump fill the fuel bowl.
RPM,s don't bump while cranking. After 5 cranks the odometer light turns off, and 4x4 flashes once, but that may be normal. It seems I may have either a bad ground somewhere, or I left some light on because the original newer batteries were killed one day after I was messing with it. Noticed security lights tried to stay on, so I had to unhook my second set of batteries.
Checked all wires for wear, none found. :dunno:
I know this is long, but I would rather lay it all on the table, rather than make this a 20 questions game. The beast just cranks. Jackass needs any help you can offer. Thanks.
NOTE: ---- I did do a quick pressure wash on the truck and under hood after picking up some mud (shortly before this died) -----
