Maybe misreading between pedal and throttle body?

If no fault showing maybe disconnect the battery for an hour?

Hmm so I've got fuel going into the engine, I think I have spark (will verify when gf is round as I can't do it solo).

Occasionally the car will fire up an immediate die. Twice this morning, probably 3 out of 25 or so starts, the engine runs. I've so far just turned it off to try again but then it won't start at all.
I'm now just sitting in it while it runs to see if it will die. 5 mins in, no problems yet.

Still no codes. If it doesn't die in 5 minutes (or when up to temp I'll disconnect the battery for an hour like you say and try again.

If it has a MAF (sorry I forget in my old age) then once running you can disconnect it and car will run nicer if it’s a MAF fault

As per problemchilds reply...if you still have the 'cutting out' issue
get the car restarted and then disconnect the MAF to see if it then runs
without cutting out. If that sorts it, then the MAF needs replacing.

Thanks chaps!

I disconnected the battery for a few hours and tried to start it, and it seems to start every time. 10/10 starts worked yesterday and one this morning worked.

How random is that! Any ideas why it would do that?

It almost seems like the car was cutting power to the spark plugs with the way combustion just stopped right away (or failed to start).

Did you look for fault codes?

I did....nothing at all! Drove it down the shops yesterday and it started without any issue.

Proper odd.  Also very worrying as I'm going to be driving this car to france in the summer and would rather not be stranded.

Check all wiring to the MAF is ok - even a little split will make issues

Update time.

Replaced both front tyres as one was losing 10 psi a week and the other had a huge rip in it from where the ex had curbed the car.  The car now drives completely straight! Unexpected result.

Not much else to say tbh.  Nearing 80k and still going strong.

Well, its an end of an era.

Yesterday Pip was picked up by her new owner.  Considering her condition the new owner got a really good deal, but I was offered a replacement car - MG ZS 180 - for a very good price that seemed to good to pass up.

Crazy thing is as soon as the sale was done I felt like I've made a mistake.

The 454 is such a brilliant car to own with its overall driving dynamics, economical engine, cheap parts and flexible interior space.  I can already tell that I'll miss the 454 more than any other car I've owned, and for once it wont be through rose tinted glasses as there is no tint needed!

Might be back one day chaps and chapettes.  Until then - M out.

Sad to see/hear you've 'left the fold' so to speak....
I'm sure there will be many memories of your 454, and that
maybe you'll hanker for another...perhaps.

Hope you gave info on the forum to the new owner ? ?

Pop back onto the forum at any time...we do not delete anyone,
we just let you 'drift away'.
So, adios.....see you again soon maybe...
