ford f-350 problems.....help?
its a 2004 f-350 larriet deisel. i belive its the 6L engine.
well i was driving it one day and it shut off and steering locked up (almost hit a house but i managed to push the e-brake)and ford took it in and said it was the high pressure oil pump, 1200dollars later it was running. now my mom was driving it down the highway and it happend agian. the tow truck guy said it was the alternator but i think it was the high pressure oil pump agian (it wont even start, just makes a clicking noise, same as before) if it is the high pressure oil pump it will still be under warrenty.
anyone have some ideas of what else it could be.
and no its not any fuses they were checked.
also the tranny went on us one day and it shifts horribly (its a auto) and it shows the tow/haul light flashing repeditly and the tranny temp is always at cold no matter what (i think a sensor just went, but it doesnt explain the shifting.
please no answers like "get a dodge"
we like our ford.
My first question would be WHY the high pressure oil pump was replaced in the first place! Was it not building sufficient ICP pressure? If so, the symptom would be an engine that CRANKS, but does not start. A 6.0L DIT engine requires 500 psi of ICP pressure (or 0.8 ICP volts) MINIMUM in order for the FICM (Fuel Injection Control Module) to "turn on" the injectors. Since 2004 is the model year where FSA (or recall in Ford lingo) 05E15 applies, it's not uncommon for a poorly carried out repair on the ICP sensor connector to be the cause of engine stalling or running rough. Just wiggling the connector on the right side valve cover with the engine running will confirm this very quickly.
But since the symptom you describe is a CLICK but no-start, that right away tells me you probably need both batteries and/or the starter replaced. This can definitely be caused by a failed alternator, or more than likely repeated excessive cranking required by your previous failure drained out the batteries.
It's not uncommon for the TFT (Transmission Fluid Temperature) sensor to fail on these 5R110W Torqshift transmissions. When that happens, the TCM "commands" harsher shifts. If the Tow/Haul light flashes, there are obviously DTCs set by the TCM. For your information, this transmission "failsafes" in fifth gear, which means 5th gear start and hold in any forward range, if the problem becomes severe enough.
HOPE THIS HELPS.
ADDED: There are TWO oil systems on your truck. The LOW pressure oil pump (driven by the crankshaft at the front of the engine) supplies the lubrication to all engine moving parts AND the HIGH pressure oil system. The purpose of the HIGH pressure oil system is to control fuel delivery at the injectors, hence the term ICP (Injector Control Pressure). The oil pressure gauge on your instrument cluster is just an ON/OFF switch, which means it only tells you whether there is pressure on the LOW pressure oil system or not. It does not tell you HOW MUCH pressure.
