Won't idle or run properly.

I'm leaning toward a dodgy wire somewhere, I'll give it the toothcomb treatment tomorrow, see if I can see anything.

[KERRSURF]

Andy, you know of anyone round here (mobile) that could do the fault code check?

[wishbone]

1st thing I'd do is get a working 3.0 along side it and make sure every single connection matches.

In the 3.0 engine repair manual that MattF hosted there is a diagnostic walkthrough with voltages etc that takes you through all the engine sensors etc. That would be the 2nd thing I'd do.

Hope you get it going soon,

Cheers,
Rob.

if you have one handy, its easier than the manual way.

There is another level of fault codes, that you have to use TE2 and E1 (rather than TE1) then with the light blicking run the motor then after go back to joining TE1 and E1 and read the flashes again, its supposed to better at detecting intermittant faults, but I've never had cause to try it.

there is also a terminal breakout box that lets you test the ECU terminals using the tester, but I don't know how many people would have one.

Cheers John, hope it's something daft and easy to spot, I know this truck inside (literally) and out...I'll keep plugging on and find it, not been beaten yet.

Thinking of getting a bloke with a proper diagnostic tool to hook up and see what it gives out.
It baffles me how a fault could appear like this with only a cylinder head swap, I'll report whatever I find, hopefully save someone else the hassle in future.

My money is on something being connected wrong after the replacement. If everything worked fine before it's got to be something physically wrong and not an untouched ecu or whatever going wrong by some coincidence

As Tony said though do a compression check to make sure the head is on properly.

yeah, know what you mean, thats why I think we're leaning towards its a broken wire from a connector or in the loom thats causing all the problems as they get tugged around doing the head.

have you checked ASAP its getting fuel at the injectors when it won't start or run? this could rule out worrying about injector issues and point to electrical faults

This would be first on my to-do list at this point.

Then I'd check for pinched wires.

Then get a man with a machine. Hypertech have one, £30+VAT to plug it in and diagnose, but I don't think it's mobile. Give them a call.

[KERRSURF]

Ok cheers for advice and info, I'll post any results I get.

I can't see a post covering it alan...have you absolutely, definitely,100% got the injector pipes in the right way. Can you compare them to another ?

It's very difficult to not get them right Andy, they are different lengths and bends so nearly line themselves up. I also checked against the workshop manual.

Who's andy?...
It sounds electrical to me alan. Keep us posted.
