The loom is wet and oily and so is the bottom of the box the ECU sits in. If oil's got in there is it RS?

Can I do any harm with degreaser, water jet and air blast to dry it out?

Looks like I'm up fro a loom but would like get it running again while I wait.

Has anyone removed the orange rubber seal from the RED plug at the ECU?
The guys that fitted my first upgraded ECU did this....it helps drain the oil away from the ECU.

I normally use 'brake cleaner' in a spray can to clean my plugs. Works better than anything else I've used. Can be quiet aggressive on some materials so take care.

You'll have to do the plug at the front of the head as well.

Have fun! Don’t hesitate to ask more queries, this is the most helpful forum out there. From DJI drones to my Ford Ranger, time and time over I just get the old, “Oh no! Buy a new one”. This is the forum that gives solutions and as a matter of fact drives me to find solutions in other walks of life when someone advocates landfill over fixing something and using dollars instead of neurones!

One thing I did that worked a treat was, instead of replacing the whole engine loom, use 7 core trailer wire to make a jumper.
Take off the rocker cover to replace the injection loom with another one. Cut the engine loom plug off. Use a pin/plastic strips/swearing to get the wires out of this engine loom-to-injection-loom plug and clean them up noting where they came from! Solder these on to the end of the trailer wiring and push them back into the plug. At the ECU end take out the wires, NOTE WHERE THEY COME FROM! and cut them off and like at the other end, pry open the metal plug things and solder them on the to ends of the trailer wire then push them back in. Voilà! You have jumped the oily wires and no need to take out the entire loom.

I removed it temporarily as circuit board cleaner etc. makes it swell up! But I put it back after the trailer wire ‘hack’!

Not water, some have pulled ecu apart and cleaned out, I’m pretty sure there is a write up somewhere, normally just spray and leave standing on edge so it drips out. I reckon there a few posts on here with how to’s .

Thanks Rob. I tried degreaser and the air gun yesterday. Today I'll have another go with metho. I'm tempted to have a look inside the ECU if I can find the little gizmo that fits the bolts. Hope you both doing well over there. Our old girl now 340K.

That makes sense now, thanks! Pity it didn't solve the prob!

Have you tried to fire off the injectors with the Nanocom?

Fuel pump working?

If not....

Checked fuses and/or swapped over relays?

Just some thoughts..

Sound from fuel pump in a td5 should be more of a whooshing/gurgling type sound .. it's very quiet when in new/good condition.

You should be able to run the fuel pump via the nanocom too.
Also, check battery volts with ign on II position. If your battery is 'on the way out' so to speak, it may not be strong enough to run the pump and or start engine at the same time .. maybe.

Next time it does this crank but no start problem .. try a fuel priming cycle before trying to start it again.
Assuming you don't know it .. ign on position II again, pump pedal fully 5 times, lift off and do nothing. I think check engine light comes on and you may hear the pump whooshing/gurgling from the driver seat.
If you have a multimeter handy, again, could be a good time to check battery for condition whilst the pump is priming.
