hi have fitted a megajolt to my mini but will not start i have a spark at all plugs also there is air being forced back out of the vac take off

check over all of your wiring! and then check again

It could be so many things, but if you have a spark on all the plugs maybe the timing is not right.

Have you positioned the pickup and trigger wheel correctly. Will the car run on the EDIS on it's own without the mj unit plugged in.

Is the map you are using a correct mini map or a basic startup map.

Have you had the engine running on a standard ignition system prior to fitting mj so know it works.

Photos may help, but start with the trigger and set the gap to the pickup to 1mm.

Try swapping the polarity of your crank sensor wires, this stopped mine working once.

But he says he's getting a spark?. Reverse VR sensor polarity wouldn't see a spark I believe.

plug leads wrong order?

Thanks for the responses guys crank and sensor defiantly ok suspect it will be a case of getting a good base map for it as I am only on the basic start up.

Oh yeah, my problem was that I had 12V going into the coil pack but no spark out.

My bad...

Should run on the base map. Mine did. As above, plus leads on in the right order?

[mini-geek]

mine starts fine on the base map or just on the EDIS.

As the system is wasted spark and the coil fires a pair at a time you would have to get the leads totally opposite to get no cylinders firing.

However I did spend a while making sure mine was correct before trying to start it.

We really need more info and photos for this one. Have you plugged it into the pc yet to check it is registering any revolutions while it is cranked over, to check the system.

Edit. Just checked and my cylinders all tie in with the numbers printed on the coil outputs.
