2012 1500 5.7L
The way I start my truck is insert the keyfob and turn directly to ''start" position.
This time it failed to start. It will only start after 3 to 5 attempt.
But I have no issue putting the Key to Run position for at least 5 sec then start the engine.(Priming?)
Battery before start is around 12.5V and down to 7.9V~11.2V during start-up. 13.7V idle and 14.2V during truck running at 1200~1500rpm.
I already replaced the WIM and the Starter.
The fuel pump seems ok and I tried to bypass the TIPM relay.
I went to Auto Zone to test the alternator diode and battery, all is Ok. First attempt of Engine Start, the tester shows that Starter drawing too much current but passed after 2nd test.
I'm not sure if the Auto Zone Alt diode tester is reliable.
Thanks in Advance.
