Warm starting problems - Earth Straps? Coolant?

Hi all,

Still having a problem with my newly aquired '99 V6 GTV. Basically it has cut out on me a few times when going along - once the engine was still running but it wasn't revving when putting the pedal down - bizare. Most of the time though it just won't start when it is warm. I have had it looked at by Heath Rd Garage in Sandbach (Italian specialists) who did the diagnostics and changed one of the relays under the bonnet but it doesn't seem to have worked.

I have also greased and tightened up the battery terminals, tried hitting the idle valve. I did try and get at the MAF filter to clean it but the bolts holding it in place are old and rusty and one snapped off so I thought I should quit with that one before they all snapped and I was stuck. The MAF filter didn't look dirty though there was a few bits of debris below the mesh.

My next guess is to look at the earthing straps but where are they located?

Also there is some condensation on the top of the coolant tank (and a very fine oily type shimmer on the surface of the coolant which is clear and green though the tank is a bit mucky on the inside). The level is a bit (not loads) below the min level. Is this indicative of a problem? obviously I need to fill it - can I use top up with any coolant or do I have to drain the whole system and put fresh in (I seem to remember something from the past about not mixing types). I have really only done short trips in it so far so it could just need a long run which I ant to do at the weekend (with RAC card in pocket!).

Any ideas for an increasingly frustrated new owner? Any help much appreciated.

Cutting out when hot but starting ok when cooled is usually the TDC sensor (also called crank sensor or RPM sensor).

Re the coolant.
Could be an ideal time to replace it, the blue/green type only has a 2-year life anyway.

Thanks for that, the garage did have a look at the crank sensor I think but decided it wasn't that.

I will drain and replace the coolant when I get a chance - looks from a few posts like a bit of a job but am getting the "workshop manual on CD" which I'm hoping will help.

Anyone know abouth the earth straps?

Had same sort of thing,Indy changed the F/Pump relay and all was good.....for 4 days.Then it happened again.Took it (back of truck) to an auto lecky place and they changed the F/Pump relay????.In the book it say's you have three relay's which you do.One is for the injection one for the f/pump and one for A/C.The one for the A/C is also a f/pump relay??Cant have updated the book or it is wrong.Best change all three relays as there all the same and only cost about £5 each.Then go from there
