Intermittent starting
Hi guys, I have a worry at the moment with my early VVC. The car will sometimes start and cut out at once. There have been times when I have had to wait before trying again. My first thought is for the fuel filter, but I have no records from the previous owner. It runs fine once it is started.

Re: Intermittent starting
I shouldn't worry about the fuel filter if the car will rev happily and/or pull normally on the road. In 15 years of multiple F ownership I never came across poor starting and I haven't had to change the fuel filter in 187000 miles.
However recently working on a car with old fuel I have encountered it and could only dilute the problem with fresh fuel and injector cleaner.

Re: Intermittent starting
It always is in use and never has a chance for the fuel to get stale. I might try a tank of higher octane though. currently on E95. Someone suggested that the choke or its modern equivalent might be sticking, but I think that is wrong as it is the same with a hot engine.

Re: Intermittent starting
I know they’re hard to get to but, what do the spark plus look like? The firing end should be light brown/grey if the plugs are happy. Black gungy plugs may be an issue.
I had starting issues & replaced the plugs (over 5 years old) problem solved. Gapping will only work for so long.

They looked fine when I did the head gasket last year.

Re: Intermittent starting
A sudden cut out like this sounds rather electrical in nature - which may point towards the multi-relay pack or the inertia switch - I'd just go round checking all these.
Sometimes the ignition switch can cause problems too.
Might be helpful to log the engine data - if the live data cuts out, then power to the MEMS2J ECU is being interupted.

I have a simple diagnostic reader if that helps.

Mk1 VVC is OBD1 so can't be read with an OBD2 reader, you need a T4 or a www.pscan.uk
