Tin top Ignition question
pewe - 29/6/07 at 08:05 PM

One for the electricians - I need to crank the engine on my tin-top until I've achieved some decent oil pressure without it firing up. It has a direct ignition pack on top of the plugs which acts as coil, condenser etc.
Is it OK just to disconnect the multi-plug next to the ignition pack to stop the engine firing or am I going to knacker the electrics/electronics?
Rapid reply appreciated as I'm due to start work on it tomorrow morning.
Thanks, Pewe

Disconecting the low tension side of the coil pack should be totaly safe. What can fry igntion amplifiers is pulling the HT leads off but leaving coil pack connected.

Depending on the car you might trigger a fault code but won't damage anything.

Thanks guys - sounds about right.
FYI another suggestion is to floor the accelerator as that's designed to allow a flooded engine to be cleared - sounds a bit hairy though partic. as it's an auto!

Mike/Adi, just to let you know that disconnecting the multi-plug at the ignition pack worked OK - no fault codes on start up. Also flooring the accelerator and keeping it down whilst cranking resulted in zero fuel going into the cylinders.
Thanks for the help.
Cheers, Pewe. :madafter spending all of Sat and most of Sunday replacing the turbo - delayed thanks to some Main Dealer's monkey who left a snapped-off exhaust manifold stud in the head - b*stards!)
