Won't start.
Hi All
I have a356 coupe replica with vw 1641cc engine. The car had always ran fine starting first time every time. Yesterday I started the car left it ticking over when I popped in the house and I heard cut out which it never does. It didn't cougand splutter it just died. It started again after afew turns and all seemed OK. I drove the car about 2 mile and it just stopped at some traffic lights and it hasn't ran since. I've replaced the coil and there's a spark at the points but not at the plugs. Any help would be greatly appreciated
Thanks in advance Charlie

Re: Won't start.
Condenser?
Coil on its way out and overheating?
Has the points gap actually closed down because there is no grease on the spindle?
Mechanical fuel pump - spring worn or diaphragms ruptured? - Run another piece of pipe from the fuel pump outlet and place in a container - see if any fuel actually comes out.
Some mechanical pumps have a small filter is this clean?
Insufficient fuel - are float levels ok, could be a blockage in the fuel line, do you have an in line filter - clean the carbs and jets through.
E5 - E10 fuel can cause havoc with fuel lines and break them up inside, which then works its way to the carbs, bits of black rubber bits everywhere.
Likewise check the valve clearances.
It will either be fuel or ignition, just a matter of elimination.

Hi Charlie
I'm running a 1641cc in a Speedster and although I've not experienced that issue, believe me, I've experienced quite a few others
but check your points gap is set correctly, and also check your plug leads and coil lead are secure. Double check your wire connections
to the coil are the right way round, since you changed it. If still nothing, try changing the rotor arm, as these have been know to fail. A sudden cut out like you say, suggests an electrical issue other than a fuel issue, cheers Colin

Hi
Thanks for the replies. I will go through what you have suggested some tests I've already done. The fuel pump is fine I removed a fuel pipe in the engine bay and fuel was flowing OK. What I find difficult to understand is the way the car just stopped no coughing or spluttering just stopped then restarted again and was running fine then a mile down the road it just stopped again. I'll try changing points condenser cap rotor arm etc.
Thanks again for your help

You’ve checked the basics ? Are the battery connections tight ? Main earth not loose ?

Re: Won't start.
Don't think so the car spins over really well but I'll definitely check. Again can't understand how it started first click then cut and restarted then cut out again after running fine. These things were sent to try us.![😜](//twemoji.maxcdn.com/2/svg/1f61c.svg)

Re: Won't start.
Check a plug lead & spare spark plug for spark.

Re: Won't start.
I had this on my campervan and it was a bad earth. Think it earths to the gearbox? Can't remember exactly, but check your earths, mine just needed cleaning at the contacts and worked perfectly.
