Can we start again with the fault diagnosis, as in what is now happening this time?

Driving up hill, cylinders 3,4 and 5 stop working?

POS changed-no difference?

Coils changed-no difference?

Does it start/crank?

Fault codes?

ECU communication?

Basics-fuel? Spark?

Is there anything you have removed to do the timing belt that has not been fully re tightened?

[hunker7]

Any way of checking if ECU is sending signal?

[newsh]

This is mental...

[hunker7]

I did indeed.

[Error404]

Did you change the POS units too?

[hunker7]

Coils are not at fault either, picked up a set from Newsh and same thing.

All honesty if its the loom and coils then Alex is your man for the coil conversion loom. Incredibly good value for money. I have one of his home made looms on my car and it was a bargain! If you have a friendly parts supplier the coils are quite cheap too... Way cheaer than going for an OEM replacement!

Don't mind his mum will ya. Take your backside down there and rent it out. Only jesting don't need the forum police along.

Get your mum to Kings Cross

The coil swap is so easy your mum could do it and have the car running ready for you to pick up

Swap isn't the problem...cost is.

I will see if I'm getting spark etc. If i cant fix it, I'll leave the car in London and get coil conversion done and pick her up before ADI.

It can be the coila s the wiring fails really easily on those original style coils. Teh wires get brittle and if you disturb them they break down and cause issues...

When i did POS connector change, cyl 3 was working, so can't be the coil.
