Australian F250

[hossdownunder]

I have a 2004 F250 with a 7.3 in it. They only offered the 7.3 or a smaller 6 cyl mann diesel motor here. My F250 has 180000kms on it has worked perfect till last week, when it started running funny at lower rpm. If its cold it will quit within 1 minute then usually a couple of times before it warms up. Some days works good some days doesn't. I have taken it to the local Ford dealer who can't get read any of the fault codes. We have changed the cam positioning sensor worked for a day then has started to run worse.

I have a 1999 F250 back in Canada with about the same Kms on it only ever replaced the CPS on it as well.

Any suggestions would be helpfull as there is only a couple thousand of these trucks in all of Australia and the mechanics here are not real switched on to wotking on them.

Any smoke or other symptoms?

How about:
- fuel filter
- air filter (any broken tabs on the filter housing or dirst beyond the filter?)
- how old/new is the oil
- what type of oil is being used (weight too)
- how cold is "cold"? (-10C?? 20C??)

I'll put my money on the injector wire harness under the valve cover.

We changed the fuel filter, air filter, oil is Fuchs 15w40 changed within 2000kms ago have always used the same 15w40 oil since new.

Cold here is it never gets below freezing or snows. But seems it will quit exactly 1 minute after you first start it, then 5 minutes then might quit after its warm when you come to a corner and it is at a lower idle.

I haven't checked the wiring harness yet, just can't figure out why we can't read any of the codes.

Have they checked the plug to the pcm?

I am trying to find a different mechanic to look at the truck, but there is no one in Western Australia I can find other than Ford that is willing to look at it. Trying to find a shop that sells code readers but no luck either. Any one bought one of those small hand held ones that run about $100.00

Those cheap ones dont read codes on our trucks. If you want one that works well check this out if you have a laptop pc Tools

I dont think those cheap autozone code readers will do much for you. you need something like this AutoEnginuity® - OBD2 Scan Tool - Professional PC and PDA DiagnosticsTo really see whats going on with your truck

EDIT: oops looks like dave beat me to it I guess I should refresh my page more often
