Do I sense the light at the end of the tunnel has been turned back on?

[Omegatoy]

injector pump timing solenoid, usually on the bottom of the pump with 2 black wires on it and 2 torqs screws holding it in., if this is the earlier one then it may not be compatible with the later management, equally the centre injector with the wire on may be to different values, it has to be one of them

You think changing them over may make a difference?  I am not convinced, but will bow to you greater knowledge  :-/

its the only thing i csn think of that could possibly cause it, iassuming every thing else is ok timing etc it can only be something like that, cos there is far to much fuel going in at tickover

Worth swapping back to donor loom and ecu?

As long as its not a train coming this way ......

not from where I'm standing

that seems a lot of work?
have a look at old engine pump and you should see the timing solenoid on the bottom of pump 2 wire jobbie, would be worth swapping it to try its only 2 torx bolts if thats set for the old loom it may be giving the wrong signals?

I don't recall plugging anything in pump apart from large multiplug on loom tray and single wire on the top?

As I feared.....the donor is the early engine and there are differences as of 1996 such as:

Map controlled EGR
MAF sensor control
Characteristic maps in ECU for pump tolerances
Internal engine measures.
Cylinder head combustion chamber shape changed and glow plug shroud altered to lower smoke production
Injector nozzles changed to radius type

Worth checking EPC as I suspect the pump changed, also, the schematis are in TIS under Service information-New Technical Features-Model Year 1996 1/2-Item 26

Should I put old loom and ECU on then?  And if so, what about immobiliser to ECU coding (don't think the early immobilisers are coded in same way)

The black wires normally run from bottom of pump to the top and back inside the pump, with just the main multi plug on the pump. You may, in fact i'm sure you'll have to cut these wires on both pumps to remove solenoids then resolder your original solenoid back onto the donor pump. Doesn't matter which way round the black wires are soldered. But i think reading Marks post you may have more problems, might be better to swop looms and ecu.s to match your engine

That may lead to immobiliser issues...

Hmmmmmmmmmmmmmmmm..........  Trouble is if your ecu is also looking for MAF  signals etc.. from your loom which aren't present on old engine then you may never get it to perform well. Youv'e come this far try swopping injector 1st see how it runs then swop pump soleniod

I have fitted MAF...

So change the injector with the piezo sensor, and then the solenoid?  Do I have to remove pump to swap solenoid, and not sure if that needs the cam/timing chains locked  :-/

Pumps are all the same according to epc

[Marks DTM Calib]

As for the starter connections...

Big red cable to main screw lug (obvious)
2.5mm² cable in Black red to connector 50
0.5mm² cable in Black/Green to connector 38H

The last connection goes to the fuel filter heater relay.

As for the control solenoid on the pump, the wiring diagram sudgests that both pumps have them.
