So, I grabbed an ISV from Dan at DDS and soaked the other two in petrol over night. The ISV from DDS didn't seem to make any difference until the car was up to temp, then it would idle so we adjusted the throttle cable to leave the throttle body open a tiny bit to aid cold starting until I find a fully working ISV and TAX'd the thing!
I enjoyed a few hours driving the beast around and was fully stoked to have it back on the road, until I went to drive the car that evening. The damn thing wouldn't fire up! Just DA DA DA DA DA and wouldn't catch. I was gutted. I left it until the morning and had another try and a bit of a look around. Nothing
I have AA with home start linked to my LLoyds account so I gave them a ring to get a guy out. Short of the long being he diagnosed a duff amplifier on the coil pack. Great. Today I picked up a coil pack from the scrap yard in newton and headed back to Dan's and picked up another two coil packs, two fuel pump relays and an ECU relay. Tried them all when I got home and none of them made any difference!
Tomorrow once I finish work, I'll try the coil pack out of my dads MK3 just to make sure, but I think the chance that I have picked up three coil packs, all with resistances within tolerances, and all three being broken is pretty unlikely.
the glimmer of light at the end of the tunnel, which is taking the MK3 to the Mega Meet on the 27th, is starting to fade
