hello 2004 was the changeover year for deleting the fuel cut off switchif your car has one it'll be at the back of the engine bay in the LH corner or the engine cowl / cabin intake vent if its not there check the fuseible link on the main battery terminal as this too can blow in an accident, if the car isn't cranking on the starter motor then this woudl back this up and the main battery connections should also be checked for tightness and corrosion

The starter motor dose crank over but will not start

hello OK that fits with no fuel supply so check for the cut off switch as mentioned earlier

There is no cut off switch
Expert:  Matt replied 2 years ago.
Ok if there's no cut off switch then the next step is to measure for 12V at the ECU fuse in the engine bayIf thats OK then use a pressure gauge to measure the pressure is at the fuel rail andif thats OK I'd consider replacing the crank position sensor as the next step

I have just gone out and started the car and it started first time it run for about 5 minutes now will not start again same problem
Expert:  Matt replied 2 years ago.
Hello OK if its intermiIttant like this then its likely to be a problem with the crank sensor I'd saybut check over the ecu power supply as I've mentioned
Customer: replied 2 years ago.
Would it have anything to do with the fuel pump
Expert:  Matt replied 2 years ago.
hello yes that too is possible which is why i've already suggested measuring the fuel pressure at the engine, this will show if the pump is healthy
