usually if there's no posts for a while the original poster has either fixed it, or is in the process of. Are you having the same issues?

hi. Virtually the same problem - I've had problems with my puma for several months. Its an intermittent problem (can sometimes be 6 weeks between break downs). Once the car has been used several times over the day it sometimes will turn over but not fire up. I was advised by several breakdown guys it was the fuel pump which has now been replaced. Guess what - today after a few miles it sounded like the fuel wasn't pumping petrol through and it stopped working at the traffic lights. It's now been towed home. After a 2 hour rest i gave it another try and it seems to be working perfectly well again.

At some stage of a previous breakdown a 15amp blue fuse was replaced in the fuse box under the bonnet - this worked for a few breakdowns but now doesn't solve the problem ( plus it might have been the 'rest' the car was given whilst i was changing the fuse)

I've now had new advice it might be the main relay fuse (which apparently is not one of the little prong fuses i have changed in the past) but i can't find where the main relay fuse is? really dont know where to go from here?

when you turn the key to position 2 you should hear the pump prime for a few seconds then turn off, if it does this, there are no fault codes stored. If the pump stays on constantly there is a fault stored, and the car is in Limited Operation Strategy (known as LOS).

if the starter motor turns the engine when you attempt to start it, then there should be no problem with that, if it doesn't always turn the engine, then it could be the starter solenoid, on the starter motor itself. If the starter only turns the engine slowly then it could be a battery problem.

other thngs to check are if its firing, there's a connector on the ignition coil, (where the spark plugs go to) check to see if its secure, and unplug it and reconnect it a couple of times, (it has a metal clip that needs to be pushed in to release it)

check all the plug leads are secure, do this with the engine cold and off, unplug them one at a time, and reconnect so you don't get them mixed up. while its off the spark plug end, give the spark plug a wiggle to make sure its tight.

do you have any other problems when the engine has started? rough running, lack of power, misfires (kangaroo-ing)?

prior to the fuel pump being replaced - when the problem occurred i wouldn't be able to hear the fuel pump engaging hence it would fire but not start. yesterday's problem was slightly different - it started and ran fine then it started losing power - as if petrol was not getting through so i had to rev it quite hard to keep it going - it went a few miles and then eventually stopped. after an hour or so it started ok but i'm scared to use it. No other problems tho

i'd try the above that i suggested and maybe pop the spark plugs out, one at a time and check for any fouling or unburnt fuel, (oily black is fouling and soaking wet for unburnt fuel) spark plugs are quite a good way of telling what condition the engine is in. The pic below will show you what to look for.

Sadly no, the problem still persists. We are looking now at trying a new 'coil pack' to see if that cures the problem.

The heater started working again by itself not quite sure how, but it has worked ever since.

I still have not got around to trying a new coil pack.

The intermittent starting still persists.

I know 2 things:

1: The engine always fires up 1st time when it is stone cold
2: The starting problem nearly always occurs when the engine has been run, when an attempt is made to restart it.

A friend suggested that it might possibly be down to a faulty fuel injector.

I think it might be the 'idle speed control valve' that is not functioning correctly, causing the engine to struggle to start under certain conditions.

The car needs some diagnostic equipment plugging in to it, just by reading your description I'd be inclined to look at the coolant temperature sensor reading to see if it's viable..
