    4.6 THOR cutting out

    I think you may find it is dying crank posItion sensor. The symptoms you describe are absolutely spot on. As the die, they start to break down when hot. As soon as they cool, they work perfectly, until they heat up again. A dead CPS will allow the engine to crank but no spark. It typically...

    P38A Alternator cable repair advice needed

    OK, you are making this way more complicated than it needs to be. Remove the cable from the alternator to the starter and throw it in the bin. It is bad practice and later P38s run straight to the battery. Get 50cm or so of 150A cable from your local electrical hobby store. Put an appropriate...

    Just a question, is your volt meter accurate?

    P38A Spare or missing connector

    P38s do have a footwell light under the cubby box, it depends on the vehicle spec if you have it fitted or not. These trucks have lots of plugs around the wiring loom unused. Once again, it depends on the spec if you have something plugged in or not. On mine (HSE) there is one dangling under...

    Strange Starting

    Another issue that might be worth investigating. If the ECU doesn't see a signal from the MAF, the engine will start, run up to about 500 RPM and then stall. It might be worth pulling the MAF plug and giving it all a squirt with contact cleaner and giving the MAF a good clean with MAF cleaner...

    If you are still waiting for an answer, the journals are 20 thou under size and the thrusts are standard.

    P38A Which fuse?

    Your fuses marked 9 are of course maxi fuses marked 60(Amp). Long nose pliers will do the job.

    White smoke

    There are two types of “white smoke” you typically see with a diesel. One is unburnt diesel. This is raw diesel that hasn’t been burnt in the engine, passing through to the exhaust. It is usually caused by late injection timing. With a mechanical set up, the cause is usually worn timing chain or...

    P38A 2000 X reg 4.6 front Side Light

    It depends on the type of LED you choose. You can get ones that simulate ordinary bulbs and therefore don't trigger the bulb failure warning. I have them fitted to all four indicators, sidelights and the reversing lights. If you do nothing else, upgrade your reversing lights to LED, the...

    P38A How does water get here then?

    Tilt the sunroof up and remove the plastic side covers by sliding them backwards. They will slide about 1/2” and then comes free. Work the sunroof open and closed. Let the sunroof park normally by itself. If it parks as you say it needs to be adjusted. Have a look where you removed the covers...

    P38A She’s Dead, Jim

    In answer to your question, yes, a duff diode will flatten the battery whilst standing. A couple of questions. Is your 12.5V at rest or running? 12.6V is fully charged at rest, once the surface charge is dissipated. If it is 12.5 running, the alternator is dead. If it is 12.5 sitting, what is...

    P38A How does water get here then?

    It is down low, or at least it was on my vehicle, behind the seat, so to speak. I'm sorry if I didn't make that clear first time! :(

    Petrol inline check valve

    Your pump is suspect. They have an anti-drain back valve in them. Clearly yours is stuck open or something leading to the issue you have.

    P38A How does water get here then?

    Sunroof drains. In the C pillar the drain tube has a connection, where it joins. This had come adrift in mine, giving exactly what you see here. Trim off, glued back together, no further issue. Of course, if it doesn’t have a sunroof, then I’d be looking at the tailgate seal.

    P38A Aircon won’t blow cold

    If the orange light above the AC switch is ON, then the AC is OFF, as the switch turns the AC off. The assumption when the car was built, is that people would run the system in Auto Mode, i.e. AC on all the time as needed by the system. The switch turns it off. As for is it engaged, have a look...
