Good suggestions, can easily check the carb next time on my own, just struggling with spark check till mrs gets home.

Just a thought.... Car was running for about 5 mins on the drive before I switched off initially.... An hour later, would this be classed as a cold start? Should I have pumped the pedal a couple of times again maybe??

Cheers Steve

On a hot day it would still be warm.

On a cold day?

When not sure how warm the engine is just start cranking with no throttle it and if it does not start within a couple of seconds give the throttle a stab as you crank.

Drew that sounds like your problem could be the ignition switch (they die after 40 years) or a bad connection in the connector on the column.

Thanks Dave..... Maybe its just me not having the knack yet??? Just been out and turned her over on key only, caught but not enough to start.... Again straight away with a tiny bit of right foot.... Fired up perfectly. Going to let her cool down properly now and try again later with couple of pumps of pedal first and see what happens.... At least I will start to understand what cold is with no choke... Wish me luck!

Cheers Steve

Don't stamp the throttle first unless the engine is COMPLETLY cold mate. Just turn the key and give it a little throttle if it does not start straight away.

Excellent Dave... The jigsaw is coming together.... Character building in my Dads words!

Was talking to my uncle over a pint at the weekend. He is a design engineer and when I mentioned this problem he said he remembered when he worked in the States speaking to a guy who was into classic American cars. He was told that our old cars dont like being started, moved a few feet to clean etc and stopped without warming up properly.... They dont restart well. He said its best to get them started and use them till nice and warm and they will restart fine. Very consistent with my problem. Anyone heard this before? Is there any truth in it? Im guilty of exactly this.... I move her a few feet to work on her, engine running for a minute or so, stop, then wont restart....Fine when shes warm....

Cheers Steve

I think you'll find all cars hate the above Steve. When we had good summers (remember them) the TVR would get used on a daily basis. The following weekend the car never felt as responsive, clean and happy (like it had just been serviced). In the winter it hated the short journeys at low rpm's for a 5 min trip or around the block before cleaning.

If you managed to use the Polara and do 10 miles a day for an entire week, it would feel and possibly start a lot better!

In short, if your gonna start it, let it run upto hot/drive it.

Engines hate short runs!

The chances are the motor is coked to death.
I bet it runs better after it has been on a run to the NEC.

Wait a minute, it's only down the road for you

Not only is this bad for any engine, it will also rot your exhaust system as you will be filling it with water.

Thanks Dave.... Im pretty sure now that thats whats happening.... A mate of mine uses a Merc Sprinter at work and even he says if they start it up to just move it in the yard, if they dont leave it to warm up a bit it wont start... Or struggles to start at best.

Cheers Steve

Sorry men, didnt see the other replies before posting..... Based on this input, im only going to start her and use her from now on.... Shecruns lovely when warm, virtually silent and nice n smooth.... Im obviously doing her no good by not warming her up properly everytime she moves. Might take the long way out to the NEC Pete!

Thanks for the advice gents

Cheers Steve

I have never had a problem re-starting a car in that situation. If they start flooding you just hold the throttle open and wait for some of the fuel to evaporate. Then keep it held open while you crank.

Give the engine what it wants and it starts. You just have to understand what the engine is asking for in any situation.

It's like when a baby cries. You have to figure out what they want. Well you might. I would just put the baby in a bucket of water to shut the damn thing up.

On Drew's issue, my truck had the same problem. I took the ignition switch apart, found nothing wrong, cleaned and sprayed it with Gibbs (Gibs again!) and it has started everytie since. I also, pulled pushed and generally gave the wiring a hard time to expose any problems and no more appeared.

That is my plan , the starter switch is only 4 years old , and I have to do exactly what you did take it apart clean it , find any bad connections and use some die electric grease on the connections ,

As far as the starting issue with the fuel related problem I drive mine every day , and it starts pretty good.

how ever if it sits in the warm sun after a 20 min. drive it will vapor lock and I usually have to let the electric fuel pump go for a few seconds and then I have to put my foot to the floor to clear it out ,

and it usually runs fine after

that but yes if you start these old beasts they need to be warm before you shut them off , I AT LEAST WAIT TILL THE GAUGE MOVES AND THAT IS GOOD ENOUGH
