My 924S has developed a starting problem. Imagine turning the key to start and all necessary components come to life..but then there's a 5-20 second delay before the starter cranks. It may do this first time, or it may take 10 or more tries. Seems to be completely random. Should I be looking at the solenoid/starter or elsewhere?
Thanks for any input

Put a volt meter on the battery and try to start it, does the voltage drop right away or only after it cranks?

Possible candidates:

Bad wiring from battery to starter
Bad battery ground to body/starter
Bad ignition switch (attach test light to solenoid on circuit 50 to test)
Bad solenoid
Bad starter
Bad connections on fuse box
Bad fuse box

Stays at 12V until the starter cranks, drops to 11V when it actually engages, then 13V after it starts

Or if you have one do the same with a remote starter switch.

Or get a new ignition switch.

Replaced the ignition switch 2 years ago. As far as jumping the terminals, still no start...but I pulled the starter and jumped it..engaged and spun. I think there's something in the bendix itself that's losing contact when installed and regaining contact when I turn it over to test...I had a Chevelle many years ago that would die when I made a right turn..then re-start..turning left was no issue. Turned out to be a loose tang in the solenoid that would swing and ground the primary circuit.

Starter wasn't generating enough torque. Hope the new one I've ordered fixes the issue
