brand new battery, connections are all clean, new as well , there is so little on the starter motor diagnostics here or anywhere, but that is where I am leaning as the issue. I am going to replace CPS , just so I rule that out , and as mentioned already replaced the cube relay on the K40 module. If I get the energy up this weekend I may try accessing the starter , at least to check the connections
This car is well cared for, 0 rust , 141K on the clock

you may be onto something 97 , that was the feelling I got when the whirring occurred, like it was not engaging, and it was cold. So that would require a replacement or can the starter be serviced ?

This car has "flick start" meaning the starter will keep on running till the engine fires, you physically do not have to hold the key to start. Just twist and leave it.
The starter will let go after 10 seconds of cranking and no rpm signal above 300. If the starter is stopping midway, you need to hot wire the starter and test it for health. Remove the box cover and you will see the K40 relay, The center connector has a thick purple/white wire. Remove this connector and wire up a jumper from the positive jump start post. Apply 12V positive to this wire with it removed from the K40, the engine should start to crank even with key not in the switch. (make sure car is in P) if it cranks good and fast. the starter is good. Next up - check the display and verify that you see the gear indicator in the gauges. does it change as you shift from P to D? if you see it disappear for a few moments, you have issues in the gear selector and it can cause this no start - and can also cause the transmission to "neutral" or go into hard limp mode. If the trans passes, I would suggest you check the connector, wiring and also the CPS - the ECU looks for the rpm signal when cranking. if it sees a corrupt signal it will stop the cranking. (just like later chevy)

Make sure the engine isn't rotating before changing any parts. Whirring from starter + engine not turning = starter drive slipping. Brief whirr then no noise / no engine rotation = starter control wiring issue or starter problem, needs further investigation. |
