Recently I have had trouble starting the coupe. It fires when I turn the key but I hear what sounds like a belt slipping. Then the engine only partially fires and stops. I turn the key again, the engine fires and good revs then it starts spluttering and stops. I have just changed the spark plugs and nothing has changed. Anyone got any suggestions as what I might try nrxt please?

Hi Guzbod,

First thing first - with the ignition off and keys out, you need to check the tension of the aux belts.

Next thing would be to put the old spark plugs back in-presuming the engine was running ok with them in.

Perhaps you have a wrongly graded/wrongly gapped spark plug. Presuming you have not put something back together the wrong way around?

Any warning lights coming on and staying on the dashboard?

If the engine was running properly before you changed the spark plugs - this should be easy to resolve.
Regards

MM

Thanks for that but the engine was not running properly before that is why I changed the plugs. The auxilliary belt seems tight enough, it was fitted by Motormech.

Spluttering and cutting out on cold start up usually the idle control valve is the first place people look at.
Removal and a clean and check the gasket is the easiest port of call.

Sounds like a vac leak to me. You'll want to go around and check that all the pipes are in good order and sealed correctly. That's a nice easy job for an afternoon. You can remove each pipe in turn, clean and reseat. And unless you're absolutely sure on the condition, I'd swap out the clips for good quality jubilee on the 'boost' section of the inlet tract. If that does not work, and it might not (but it's a cheap first step) you'll want to consider the MAF sensor. Mine would barely start with a duff sensor.

You also want to investigate the squeal fairly urgently. It might be nothing as some belts just make a noise but equally it could be a bearing as there's quite a few down there. Again mine spat it's power steering support bearing, which killed my engine...

Once you've got you engine running right, you just need to get someone to listen as you start the car. It should be obvious where the noise is coming from.

Also might be worth checking the insulation on the injector wires for cracking and possible arcing. Those and the coilpack wires suffer from degradation due to heat and age.

Sounds like a fuel starvation issue, check the yellow connector of death and listen to see if the fuel pump primes when you turn the key to MAR.
