Hi I have a 2.7l engine. I have always had a issue starting the vehicle. It normally takes 2-3 cranks to get it to start. The cam and crank sensors have been replaced. The fuel filter, pump and pressure regulator have also been replaced. And recently the plugs, starter, battery and coils ( the coil recently failed). With all that done, I still have a starting issue. Sometimes 2-3 cranks. Other times I just about run the battery down trying to get it to start. I am at a loss.
