Hi all
I'm trying to get my newly built Vauxhall/Opel 1.6 16v (x16xel) on twin 40's using a megajolt to start. It's being a pig!
It Cranks pops and blows back through the carbs but doesn't fire!?
Today I've checked the carbs fuel seems fine floats all fine, spark seems fine new plugs and firing order is:
Cylinder num: 1 2 3 4
Firing order: 1 3 4 2
Coil pack turret to cylinder numbering: 1/1, 2/3, 3/2, 4/4
Plugged into the laptop I can see the TPS is working and I also checked that the VR sensor is 'sensing' by putting a multi meter across the terminals.
Anyone any ideas what else to check?
Cheers
Simon
Trouble starting - any ideas?

I'll give swapping the plug leads about tomorrow (battery is flat now).
In regards to the coil firing order does it fire 1,2,3,4 as per the numbering next to the coil towers?
Some seem to think that 1&4/2&3 the coil sides fire together (connector facing down 1&4 to the left of coil 2&4 to right) and other say it's as per the 1, 2, 3, 4?

EDIS is wasted spark, two plugs will be firing at once. One of those cylinders is on the compression stroke and the other will be on the exhaust, where there is nothing to burn so it is wasted.
correct, when looking at the coil where the plug is on the bottom, the left half will fire then the right half, assuming your wired it correctly. Left should be wired to coil 1 on the edis module, right as coil 2

Start by unplugging the MJ, take the plugs out and put a timing light on it, you should see 10 deg or somewhere near that. If so that is good enough to start it.
If still popping, forget the thoery and just swap the leads around, there is only a few combinations.

If you think you can or can't...your right!
Right I've sussed the error of my ways! Like a complete dullard I've mounted the VR/crank sensor at the point of the missing tooth but not tdc so the engine was trying to fire 90 deg before tdc.
But now I have a new problem where I need to mount the sensor at tdc the anti roll bar will clatter it once the car is dropped (arrrgghh!)
So I have two new questions:
1: are there any shorter sensors I could use as mines too long?
2: can the sensor be mounted side on to the trigger wheel to detect the gap?
