That engine doesn't have glow plugs.
It **might** have an intake heater. It would be on the air intake pipe going in to the engine and have a couple of 2 gauge or so cables gojng to it.
either way that shouldn't make a difference to starting at this time of year.
If the ABS light is coming on, and the engine light is on, there should be other codes available through the dash. can you try pushing the button on the cluster to cycle through the codes, and post what they are?
If there are no further codes, I would make sure the fuel filter is a detroit diesel/ mercedes part.
I would also check under the cab to see if there is an inline fuel filter in the plastic fuel line, and change it or eliminate it. Freightliner used to bury them under there on the business class trucks.
I would make sure both fuel filters on the engine have been changed, the strainer and the filter.
after that, I would remove the fuel supply and return lines where they enter the fuel filter housing. the fittings attached directly to the bowl are check valve/quick release couplings. remove the fuel lines by unscrewing the female fitting just below the bowl (SHOULD BE ELBOW TYPE FITTINGS) and look for debris in the quick release fittings. This is assuming this is a pre -07 engine
After that, I would make a line to go from the return line on the engine to a pail, and run the engine and look for air bubbles in the return fuel.
It's probably not an injector, but fuel loss from one of the high pressure pipes can make them hard to start. look for fuel leaks on the driver's side of the engine.
It could also be a long shot I've seen a few times : batteries/ cables /wiring going to the ecm were in such bad shape that there wasn't enough juice getting to the ecm until the starter stopped cranking or ether was used to lighten the load on the starter.
