help on low injector code P0282

Alright I did egr delete, put back together... then
air flow into degas bottle... so
did head gaskets and studs... then
had some rough run and code P0282 (low injector circuit on #8)
so...
I was thinking at 155K miles maybe all remanfactured injectors is good PM anyway so...
got them replaced and still get same code P0282

Seems it is wireharness or FICM, or so I think

Can I do simple diagnostics with a multimeter on voltage at FICM and compare to voltage at injector plug. Maybe do resistance testing from injector plug to computer plug (this would be a true test of wire and connectors only)

suggestions or tips on my next step would be appreciated.

check your wiring harness good. Around FICM, front driver valve cover and intake bolts are common places. wiggle the harness and pinch it when engine is running and see if it stumbles, or cuts out. Also you can pressure wash engine while running to see if harness cuts out. common problem. Could be ficm though. I'd check harness first though.

Thanks Chuckles,
So what are common failures in wireharness? Sounds like you are indicating damaged wires at stress points rather than at connectors.

look here:

17961 2003-2004 SUPER DUTY F-SERIES/EXCURSION 6.0L - DRIVEABILITY - WIRING HARNESS CHAFING
SOME 2003-2004 SUPER DUTY F-SERIES AND EXCURSIONS EQUIPPED WITH A 6.0L DIESEL ENGINE MAY EXHIBIT A CRANK NO START, RUNS ROUGH, ENGINE MISSES, BUCKS/JERKS OR LACKS POWER CONDITION. THIS MAY BE DUE TO THE FICM WIRE HARNESS CHAFING ON THE UPPER LEFT VALVE COVER OR VALVE COVER STUD, NEAR THE FICM. REROUTE WIRING AND/OR INSTALL VACUUM CAPS ON STUDS CONTACTING HARNESS. OTHER POSSIBLE SOURCES OF CHAFING ARE IDLER PULLEY UNDER THE THERMOSTAT (WIRING ROUTED AROUND POWER STEERING PUMP), LEFT FRONT VALVE COVER HOLD DOWN BOLTS/STUDS, EBP SENSOR BRACKET AT THERMOSTAT HOUSING, RIGHT VALVE COVER AT GLOW PLUG MODULE, AP/ETC PEDAL WIRES CHAFING AT STEERING COLUMN (ADJUSTABLE PEDAL ONLY), PCM HARNESS CHAFE AT BATTERY BOX AND HARNESS CHAFE NEAR C1443 (LEFT REAR CORNER OF ENGINE COMPARTMENT) CKT 1044 (WH/YE). REPAIR AS NEEDED.


Not necessarilly the connectors. the harness basically gets rubbed raw at certain points and the wires will either short to ground, to each other, or break in half.

FIXED, YAY!!

The number 8 injector connector had 2 wired that were loose in the connector (wire harness plug that connects to injector), one of them when inserted firmly clicked in and loocked as it should (possbly not done properly at the factory), the other one had to be convenced to stay, 2 pinhead size dabs of 90 second epoxy on the metal wire end connector pic, then inserted into the plastic connector body!

Easy as standing on your head in the dark on a rocky slope of a desert mountain with cactus and insects all around. If it was not for the awesome way this truck ran I would be snivelin about how tough they are to work on.

OH and I almost forgot to mention, it is now running GREAT! idles smooth, starts right up, runs smooth at medium throttle to full throttle, just like new or better (due to mods)
