Little Bit of Help If You Can??- Non Start

[Michael Woodford MST]

Right basicly I have a Ph1 172 and a 182 full fat and the are both suffering from the most annoying problem ever!- They dont start lol

Heres some background info

172- I bought this off ebay as a non runner. The last owner took it to renault and they can't figure out whats wrong with it. He then changed the ECU, chip and the little circut board thing thats part of the immobliser. It still didn't start. Then i Brought it. The fuel Pump primes and runs when cranking. The Injectors have a 12v feed and are firing. The coil however has no 12v power feed and therefore is not firing the sparkplugs. It has had new Plugs, Leads and a coil by the last owner.

182- Again I bought this as a non runner. The engine had blown up. The last owner took the old engine out but couldn't put it back in. so after sitting for 8months I brought it. I have installed an 8000mile old engine and it will not start. It has exsactly the same problem as the 172. The fuel Pump primes and runs when cranking. The Injectors have a 12v feed and are firing. The coil however has no 12v power feed and therefore is not firing the sparkplugs.

This problem is really doing my brain in! No one i talk to has ever heard of this problem, yet i have 2 cars doing exsactly the same thing!

Has anyone got any ideas?

Also is there a relay that has to switch to turn the coil power on? if so does anyone know where it is and what triggers it.

Any help will be greatly appershated.

Thanks

Mike

Sounds like immobiliser issues.

RS Clio's ECU's confuse me no end!

I sold my ph2 172 due to ECU problems!

172 - I presume he changed the keys as well?

182 - After sitting for 8 months without a battery connected (I presume) this could be an immobiliser issue too.

I'd say they both need to go to Reno for them to unlock the ECU's direct from RUK!

Immobiliser did cross my mind.

But if you take the chip out of both and try and start it the fuel pump doesn't prime and the injectors dont fire.

That was my little method of seeing if the immobiliser was turning off.

Also the red led goes out as well when the ign switched on.
