2007 Chrysler aspen no start no injector control

A factory or a professional scan tool would be a great help in diagnosing this problem ! The PCM - engine computer supplies a ground to the injectors if all the right inputs to the PCM are there ! Crankshaft position & Camshaft position sensors being the most important . Plus if there was an anti-theft system problem , in most vehicles ,the injectors would be disabled ! Does the check engine light come on when you turn the key on , not to start , just on ? Does your vehicle have a Tachometer ? When cranking the engine does the tachometer move ? Also is there spark ? Did you pull a plug wire an hold near metal on the engine while someone else cranked the engine ? Check for power an grounds at the PCM , no power , check the ASD relay ! The ASD relay powers up the vehicle an they do go bad ! short inside or open circuit etc...
