What would cause a Suzuki Grand Vitara diesel to be slow to start? All four heater plugs are good, and it starts quicker if you pump the accelerator when starting.

Hi Mattie,

That really could be a number of different things. It's most likely excess air getting in somehow, but it could also be the crankshaft sensor. Best thing to do is to bring it to a mechanic that can interrogate the car's computer via a diagnostic tool. That should reveal any error codes that will speed up fixing the car.

Let us know how you get on.

air getting in, crank sensor?
