check ecm fuse
dead battery or starter
Need to check the battery conections and the starter wires and starter.
Check the starter and the solenoid. Make sure that the cables from the battery to the starter are tight and are sending voltage.
In the car electrical system, the starter motor is the first stop after the battery, so the problem has to be with that.
You wired it up wrong, or the new starter was defective.
I have heard the alternator does it,cold drains the battery too,if it's not started for awhile can kill it.
Check the battery cables or starter.
Dead battery? Loose or dirty battery cables? Bad starter solenoid? Bad starter? Neutral switch?
test for battery voltage at the starter motor if you have it then test the engine ground if both of those are ok you need a starter
Voltage Regulator?
Weak battery?Bad starter?Timing set too far advanced?
Double check the battery cables at the battery and at the engine, be sure they are clean and tight.
