Hi I have a multipla 1.9jtd it just cut out while driving and won't start I I use quick start it starts and idles but if you drive 100m it cuts out I've replaced the crank sensor but no luck I've also checked fuses and relays is there anyone that can maybe help sort out the problem I've also had two different diagnostics done but both show no faults

Hi,
Welcome to Fiat Forum.
Sounds like poor fuel supply. Possibilites are:
Blocked fuel Filter
Water in fuel / fuel filter
Failed low pressure pump
Blocked tank pick-up
Bad fuel

If you had re-filled the fuel tank shortly before it stopped look at water bad fuel, blocked pick-up. If not suspect pump, blocked filter, water in filter. The first and easiest thing is to drain the fuel filter (check for water in drained fuel) and fit a new element. Next is to check fuel pressure. I don't knoe where the low pressure pum is in your car.

HTH,
