My daily driver has a really annoying problem, when the car gets hot it refuses to start once ive turned it off, have to wait for it to cool down which is a pain when stopping for petrol etc. Mechanically its in very good condition, had a top end rebuild recently and perfect compression in all cylinders, new starter etc.
Was told when I bought it that it was a wire off the starter but ive played with it and no joy, would changing it for bigger grade wire do the trick? What else could it be?

What does it do when you attempt to start it?

Does it just turn over or does nothing happen when you turn the key?

[sailorbob]

What car?

I had this it's was the TPS unplug it next time if it won't start there not cheap get one second hand as the not far off £50 for a little switch

[dannyboy]

Its a frst, sailorbob

I have a spare TPS on my other fiesta so ill swap it over and see what happens, nothing happens does not even attempt to turn over.

Sounds like a starter motor problem then. Try cooling the starter solenoid with lots of cold water when it does it and see if this makes a difference.

mine was dead too if all the dash lights come on then sounds like tps if no lights then the c.p.s

Thanks for the quick replies guys some of the loom is a bit tatty so I was going to replace most of the plugs anyway, ill get on the case.

Its got a brand new starter motor on it but ive got a more powerful one on my zt in the other car which is going on soon.

TPS and CPS will not affect cranking, the ignition switch to starter motor circuit is independant of the ecu.

[dannyboy]

So does that still indicate a starter motor problem? Think ill just change evrything over

If it's not even turning over when hot but cranks fine when cold then 99.9% of the time it is the starter motor or solenoid playing up. Occasionally it's the wiring breaking a connection because it's expanded when warm. Try the cold water test.

100% gaurentee its the wiring to the starter mate

make sure all the wiring to the starter is mint, and the connections are clean etc

mine use to do the same all the time turned out the rubber grommit on the staarter, the wire inside had corroded to buggery id also put some heat wrap on it just to make sure heat dont effect it aswell

Sounds 110% what mine did i just unplug the TPS and the car just started it got worse ever week

unplug your CPS then and see if your car starts he said his car will not even crank over

Its a frst.

u kept that quiet danny



got any pix mate

[ianFRST]

i doubt its the tps or cps, they effect throttle and things when the engines running

it will be down to a wire, as said, when its hot it expands, and looses the connection

[dannyboy]

I bought Daves(t2rst) old one Mikee, its quite clean but not mint, ill get some pics up when ive made a few changes to it

Thanks again people sounds like you have sorted the problem

99% chance it's the 12v+ wire to the starter.
It's probably corroded by heat and age..

It's the cheapest .. and easiest thing to do first..
If that will not help, replace the starter (and fit a heat shield) as this could be knackered by heat and age too.

I replaced my wiring .. and it got a lot better.. but eventually the starter itself 'stopped' .. and i recently replaced it by a brand new 'motorcraft' item ..

I used a 1.6 16v (1.4kw) starter from a MK5 escort .. this is a reduction starter and needs less peek current to start.
