Was planning to head to Brighton but so far my car has cut out three times. First in heavy traffic (high coolant temp), got it going by keeping the revs high, died again, borrowed some tools to remove the coil pack and stretch the coils over the spark, since then has died twice more, the last time was while driving at around 3000 rpm.
Any ideas on what to check while waiting for the AA?

Btw it's a 2.0 l Saab b207 which is what made me check the coil pack springs.

What temp you got the coolant fans activating
And does it bring the temps down ??
Could the water pump be a issue

might be a stuck (shut) thermostat causing the over-heating ?

Fans kick in at 98. Temp drops back down to around 86 which remains constant so doesn't seem to be a cooling system problem.
Just happened again on the M3. Not fun. Seems letting it cool down works, got 45 minutes out of it this time. Current thinking is coil pack or fuel evap

Seems temperature related. We managed about 45 minutes from cold. Only ten minutes after a ten minute break.

Anyway to drive with all fans on? Internal and external? This should lower temps.

I would say it's the crank sensor.

Crank sensor would come up as an error code (I think). Finally home, lots of back roads from the bottom of the a34 but no more breakdowns. Funnily enough, I put more fuel in and haven't had a problem. Makes me wonder if it's a contaminated batch as the first tank was okay until it was half empty. Since diesel or water are higher density, it might not show straight away. Going to pop over and see if they can provide me the fuel CoA

I have heared of return fuel heating up to much causing issues when driving slow from another dutch guy.
Not 100% sure how he fixed it though.
Next run out, touch your return line just for fun.

Oh yeah, I forgot you could get ecu's with data logging... Things I dream of.Crank sensor would come up as an error code (I think).

That's Dominique on an uprated fuelpunp (and PA tank)...
He gets vapour lock on lower fuel levels when it heats up too much. Quick remedy; fill up tank.

hmm, this is the first long, hot day run with an uprated fuel pump. The AA man thought it was vapour lock too. In the end I ended up opening the fuel filler cap each time I stopped, but there wasn't any pressure build up.

And you have a Pro Alloy tank? It's not pressure/vacuum build-up, just fuel temperature that creates gas bubbles...

DW65c
Advantage (for me at least) is it drops straight into the existing VX fuel canister and pulls less current, which should also mean less fuel heating.
