16v engine problem

I have just had my new ashley exhaust fitted to my newly converted 16v golf. And it sounds amazing when not in gear.
Because the car hasnt moved for about 10 months and it has an entirely new brake system. I drove it out of the garage realy slowly.
But then i decided to give it a little more throttle and it suddenly died and backfired at the same time.
has anyone else had this problem?

Does it restart?

Might be a loose wire on the LT side, or something like that.

no it doesnt restart. When you try to restart it, after a while it just back fires.
I think there are no loose connections.
Could it be the fuel mixture?
If so which way do i need to turn the screw to lean it. ( its K-jet)

No, it sounds like an ignition fault.

Hmmmm

could the dizzy be broken

It could be anything, you'd need to do tests and look at the car, etc. 1st thing would be to check for a spark.

There are a few electrical connection which i havent connected such as
The WUR and there is this other connection just under the dizzy which has nothing connected

I find it strange because it revs well when its not in gear

I had a similar issue with one of my swaps.    Turns out the body ground was going bad.   the engine was actually grounding through the exhaust which was rubbing on the under side tin.   when you would accelerate it would pull away from the tin and break the ground and stall.
at idle it was fine.

Try running a temp ground from the head to your battery Ground.

Good luck.

I thought you might be onto something there bigcaddy but it wont even start now.
I turns on the starter motor and then back fires after about 5 seconds

how close is your distributor to the brake master cylinder?     I've had a 16v rock enough once to hit the distributor cap on the proportioning valve enough to snap the rotor.

Double check your engine timing as well.  I've had teeth rip out of a timing belt already.  hope this isn't the case.

does it not run at all even if you run that extra ground wire?  

Like Paul C asked…   do you have spark at all?

yes i have spark but i think it should be stronger

Is it significantly stonger off the king lead, than one of the spark plug leads? If so then have a close look at the dizzy cap and rotor arm.

just checked the spark from the king lead and it was alot stronger.
So i then took dizzy cap off and the rotor seems wobbly, which i know it shouldnt. So i will replace it and let you know how it goes.

I have just driven the car up the street and the engine works well.
I took it easy though cos the breaks feel realy spongey and you have to pump the pedal a bit before you stop.

So thanks once again Paul
