Did start, stalled and now won't start. Any ideas?

[TimmyArt]

Hi Chaps.

I went to start my 450 after a few weeks without driving it. Bad idea I know, should have used it mor regularly.

Anyway, It started first time, backed it out of the garage then it conked out. It then wouldn't start. It was trying to and seemed to fire on a couple of cylinders but not enough to start it.
Probaby running the battery down now trying.

Any ideas?
Thanks in advance

Have you cranked it over with your foot to the floor?

Just sit there with a cup of coffee and try again 20-mins later!!

or waste a lot of time and change the plugs for dry ones!!

Best advise is usally to get the drive way & gates sorted. Start and drive out and on your way without leaving it to tick over whilst you close everything up!!

HTH?

Annoyingly when it did start first time, I didn't give it some beans to hopefully keep it going but then i didn't know there was a problem.
I had left it half hour before trying it again but that didn't seem to help. Perhaps will try again in a bit.

I had this problem, turned out it was my fuel cut out switch, can you hear your fuel pump?

Yes I did. It has fuel in it too.

Have you left it for 5-10 mins then as said use the thottle to help it pick up when cranking over? sound like it has flooded.

I think you find the suggestion was to crank it over on wide open throttle this has the same effect as removing the fuel pump relays and allows the fuel to be drawn out of the chambers.

Woooooooooooooooooooooooooooooooooooooooo!!!!!

I tried the foot to the floor trick and after a few persistant efforts it came alive! It's never sounded so good. It seems wierd putting the foot to the floor but it does seem to work. Extremely useful advice. Thank you all for your help.

My Vintage Riley wouldn't start either so I thought the world was against me today. That needs more work I think.
The one good thing about not driving the TVR for a while is that is seems like a very fresh experience again driving it round the block. Very exciting.

Thank you all again

I have had this a couple of times, nothing but good old fashioned flooding!

Quick fix, get a tow start, worked for me twice after cranking over forever!

Downside is, seeing a tiv towed, c'est la vie!

Sod crawling about in the foot well in this weather when all you need to do is push the loud pedal, Always start with the simple stuff .

Glad you got it running

Are you saying that cranking with your foot to the floor causes the ECU not to inject any fuel at all? If so, that really is worth knowing!

[fenderbender]

Putting foot to floor will not cause ECU to stop injecting fuel as otherwise your car would cut out on full throttle! All that is happening is that you are allowing maximum air flow into the enbgine, and hopefully pumping out some of the over-rich mixture which is infecting the cylinders. With any luck the plugs will not be fouled or you will have to (a) wait until the fuel on the electrodes evaporates, or (b) take the plugs out and dry them off (a gas flame does the job nicely).

This was an old dodge when cars had carbs, starting required pulling a manual choke knob, men were men, women were women and new car bodywork rusted through after 12 months...

True, I spent more on Isopon filler then the cost of my first car, (Austin 1100)! .

That's not what I asked at all!

It would be perfectly possible for the ECU to have the following logic in it:

IF (starter is engaged) AND (full throttle) THEN don't inject any fuel.

Somebody said that cranking on full throttle has the same effect as removing the fuel pump relay, which made me wonder if this is what the ECU does. Anyone know?
