Hello, sometimes, not all of the time I turn the key to start and the starter doesn't "turn" the car over.I just get all of the dash lights, if I keep turning the key to start it sometimes it will turn the engine over fast sometimes fast, sometimes slow! I had the battery, and the alternator tested, both are good.I looked at the terminals, and the starter for corrosion, none there.I at first thought I was the battery so I ran a 6amp charge on it showed full charge(engine running) but everytime the voltage regulator would "kick in" to charge the needle on the charger would "flip" to the no charge side until the regular released its charging state of contact. Is that normal, any idea's for me, and thank you! Glenn

You cannot use the charger for testing the alternator chagre. It automaticlly turns off when the alternator is providing the correct charge and battery is fully charged.

Erratic starter cranking can be due to a failing starter motor, poor ground or battery terminal connections.

Bench testing of starter is not going to show anything conclusive as starter is working but its capacity could be below par.

The other possibility is a failing battery. You need to test tthe battery high rate discharge when it is turning slowly.

Did you test the battery high rate discharge and alternator charging?

P0863 - CAN communication
P0700 - Fault detected in transmission control.

Above 2 are not direct faults pertaining to any components except the TCM. Try disconnecting battery and resetting the codes.

P0134 - HO2S CIRCUIT NO ACTIVITY DETECTED (BANK 1/SENSOR 1).

Check the fuses and HO2S sensor.

Thanks for the input. The codes you retrieved did not show anything about crank sensor and cranksensors do not cause the starter to crank slowly.

Most probably the battery wast not at full charge then.

Glad to know you have fixed the problem.

Have a nice weekend.

Just wanted to do a follow up. It was not the crank position sensor(misdiagnosed by a local flunky)! It was the battery, had 2 faulty cells, I put a DEKA 1000 CCA battery in it, all good now, thanks for the educated, and correct to start with replies!
