5 year old HS w/ 50k miles ... Initial starting became increasingly delayed 20/30 seconds ... warm/hot start O.K. Replaced in-tank fuel filter/pump/strainer ... now car starts for 3 - 5 seconds then dies ... half a tank of fuel ... acts like little or no fuel pressure ... Is there any additional priming or air-in-line evacuation procedure required ... could fuel (injector) pressure regulator now be the affected?
Need to have the fuel pressure checked at fuel rail to know for sure if there is a fuel pressure problem for sure. There may be a in line filter as well, you can also do a check of the pressure regulator by pulling the vacuum line off of it then try starting the car with it off and see if it runs, if it does the regulator is bad, but IF it doesnt run doesnt necessarly mean it is good, a lot of fuel filters have a bypass wich allows the gas to bypass the filter when it is full bad thing is the debris can then plug the injectors causing problems, or there could be a loss of signal to tell the injectors to give fuel to the cylinders from an electrical or a sensor failure. So it is best to test the pressure to know for sure if it is in the fuel line or the injectors if it is truly being starved of gas. hope this helps
