Really strange. I've been using the car everyday since November, never given me a problem.
It was up to running temperature, (temp gauge just over half way) It was absolutely chucking it down with rain. Carwas running as normal, no misfires or anything. I need to change the downpipe as it's blowing like a goodun (new one arrived today)
It's fitted with a Clifford G4 alarm.
Jumped in, started the engine, it ran for a few seconds and just completely shut off, no noises or anything. Then it just turned over and over. I got out, locked it, unlocked it and after a while, it started again....then it done it again.
My gut is telling me the immobiliser BUT it could be something else. It's doing my head in.

Do you remember what the fuel pump was doing?

No, I can't remember. I can't remember if it primed or not. I've just gone back to it, unlocked it and it's fired up straight away. It only started doing it after the rain....
I'm going to use it for work in the morning. The fuel pump usually primes when I turn the ignition key so I'll check.

8v has the ignition amp on the back of the bulk head about 3inch square Ali plate with a black box on
. My mk1 ran just like that as the heat sink got hot it cut out after a few mins it ran again and cut out
It's worth a try . Hope it helps

Would it need replacing? The downpipe is blowing at the flexi section, could this be exposing the amp to more heat than usual?

Right, I was told that it could be the curse word Clifford concept 300 alarm that's fitted. The immobiliser playing up and cutting power etc.
I decided ages ago to remove it and had got hold of a complete wiring diagram for it so today I decided to remove it. I was surprised how easy it actually was. The main control unit was behind the centre console and I just followed the wires to where they were spliced into the loom. I cut out, soldered and replaced where needed and Bob's your uncle and Fanny's your aunt, one big pile of wires and tat in the bin!
The fuel pump is priming everytime I turn the ignition on now.
Going to take it out early and see how it goes, fingers crossed!

Poorly installed Cliffords can be ripped out in next to no time. In my old Pug 306 GTi-6 (where the brain was not even bolted/velcro'd down) it did not even take me 30 minutes to gut the entire system. Surprisingly it was semi wired out due to causing issues.

Surprisingly it was semi wired out due to causing issues. Same here too. It had been fiddles with in the past and the concept 300 has an especially bad rep for problems. Even if I haven't solved the issue, I'm glad the alarm's gone, didn't trust it at all. |

Been out in it all morning with no issues whatsoever so it looks like it was the Clifford!

Glad it's solved  To be fair to the Cliffords the alarms themselves are not too bad, but some people really should not be in the alarm installation business (but then I do say the same about some characters in the LPG trade...). There is more to an alarm than simply ensuring it locks and opens the doors, and installing one correctly is never a cheap exercise. . |

Funny this has popped up here as I'm having the exact same issues with mine.
Firstly, I ALWAYS wait for the fuel pump to prime before cranking.
The first time this happened, I'd come out from work after a torrential downpour, jumped in, started it as normal, it caught and ran for 2/3seconds then died.
I then proceeded to spin it over in hope, it seemed to try to catch/fire but only when it'd been spinning over for 15-20secs did it make any real effort to run (but not actually run, if you know what I mean)
I almost completely flattened the battery that first time, but I had the foresight to wait for 5mins and have a cig before trying it again and low and behold it started (albeit running on 3pots) so I held the revs at 3k until it got warm before driving 250miles to a music festival.
After being parked for a week in a field, i wasn't expecting much, but it fired up dying almost instantly. I waited 20mins, went back to it and it started and ran fine the 250miles home.
Since then its done it everytime when started from cold. Sometimes if it catches and I'm on the throttle quickly enough I seem to be able to keep it running with liberal right foot, but it sounds like its running on 3 maybe even 2pots.
It has also, once, started normally then cut out 1/4miles down the road only to restart immeadiately.
As soon as there is even a hint of heat in it it behaves perfectly.
I'm gonna stick a fully charged battery and new fuel filter on it tomorrow to see if it makes ANY difference, but I have a feeling Ive heard about an issue like this being caused by a temp sender before....

Yep, blue temperature sender is usually the culprit for your particular problem mk14dr. Genuine ones are cheap enough, if you buy aftermarket you will be changing it again in a matter of months.
