Hi there,

as you have not mentioned which motor is fitted, i will go with a general reply, i would first be checking the cold start injector if fitted, and having the fuel pressure and pressure regulator tested. Try this, turn on the ignition and wait 3 sec before cranking, if it starts up with out any problems i feel that it will be a fuel related issue.
