Eric,Have you checked to see if you have injector pulse while cranking?Has the computer system been scanned to see if there are any fault codes setting?
No codes. have not checked injectors
If it will start on added fuel then the next step would be to check to be sure you have key on power at the injector and a pulse while cranking. Check this and let me know the results?
How do I check for power at injector? I have snap on ehos pro.
You can check for power with a standard 12 volt test light or a volt meter by checking for battery voltage (key on) at the power side of any of the injectors. You can also use a standard 12 volt test light to check for injector pulse. Place the test end of the light on the power wire on any of the injectors and the ground end on the other wire and crank the engine over. If you have pulse the light should flash while cranking.
