Starter questions starter sluggish the battery and alternator work fine and there are no loose wires yet it hesitates one time and then the next its fine
Do a voltage drop test on starter , cables ! Check the starter relay ,PCM energizes the starter relay . Check power an the control circuit of starter relay . Videos on you tube on doing these checks . Starter Voltage Drop VEHICLE RELAYS Testing from the relay base
Testimonial: "thanks ill try that this car has the starter that keeps cranking on its own after you just turn the key and let off till it starts i think maybe that's where the problem is"
No this system doesn't keep cranking after key is relesed .
Starting System Description and Operation
The PG-260 D is a non-repairable starter motor. It has pole pieces that are arranged around the armature. Both solenoid windings are energized. The pull-in winding circuit is completed to the ground through the starter motor. The windings work together magnetically to pull and hold in the plunger. The plunger moves the shift lever. This action causes the starter drive assembly to rotate on the armature shaft spline as it engages with the flywheel ring gear on the engine. Moving at the same time, the plunger also closes the solenoid switch contacts in the starter solenoid. Full battery voltage is applied directly to the starter motor and it cranks the engine.
As soon as the solenoid switch contacts close, current stops flowing thorough the pull-in winding because battery voltage is applied to both ends of the windings. The hold-in winding remains energized; its magnetic field is strong enough to hold the plunger, shift lever, starter drive assembly, and solenoid switch contacts in place to continue cranking the engine. When the engine starts, pinion overrun protects the armature from excessive speed until the switch is opened.
When the ignition switch is released from the START position, the CRANK relay opens and battery voltage is removed from the starter solenoid S terminal. Current flows from the motor contacts through both windings to the ground at the end of the hold-in winding. However, the direction of the current flow through the pull-in winding is now opposite the direction of the current flow when the winding was first energized.
The magnetic fields of the pull-in and hold-in windings now oppose one another. This action of the windings, along with the help of the return spring, causes the starter drive assembly to disengage and the solenoid switch contacts to open simultaneously. As soon as the contacts open, the starter circuit is turned off.
Moving the ignition switch to the START position sends a 12 V signal to the PCM Ignition Crank Sense. The PCM then grounds the control circuit, which travels through the Park Neutral Position switch, of the CRANK relay . When the CRANK relay is energized it allows voltage to the starter solenoid S terminal.
I would also have vehicle checked for DTC'S diagnostic trouble codes !
The engine control module (ECM) supplies a ground path for the STARTER relay when start enable has been requested. The ECM monitors this circuit for conditions that are incorrect for the commanded state. If the ECM detects an improper circuit condition, STARTER relay DTC P0615 will set. These codes do not turn on the check engine light !
DTC P0616 ,DTC P0617 ,All have to do with starter relay .
