My 1973 2002 does nothing when I turn the key, but if I keep the key turned for 5 to 10 seconds, it starts right up. Sometimes I need to keep it turned for 20 seconds. Bad starter? flat spot on starter? electrical connection to starter? Battery is brand new. There is no clicking during this time, just silence. Thank you for your help
How old is the starter? How did it behave before this problem started? How is the voltage at the starter compared with the battery? Have you confirmed the grounds are solid, especially the chassis-block ground?
FWIW, I replaced the old Bosch starter in my 02 last year with a mini starter I bought cheap on ebay (<$100) and it spins a lot faster than the old one did with lower current draw. If yours is old you may just want to replace it on principle.

Not sure how old starter is, just bought the car, had it shipped in from overseas and it came this way. Thought it was a dead battery, but just for the heck of it, kept the key turned and after nothing for awhile, it started right up. I will check voltage and grounds.
Mini starter will bolt right on? Also read someone used M3 starter. Thank you
This is the starter I used: https://www.ebay.com/itm/NEW-STARTER...item2160b8d2a4
I'm guessing you've got a combination of questionable grounds and a sticky solenoid. You need the grounds solid for a variety of reasons, but I'd still consider replacing the starter even if fixing the grounds solves the starting problem for now.

Bad grounds on our old cars are a big problem and can cause such situation as you described it. Had a similar situation with a friends car recently, looked like the battery was empty as the starter was just clicking, checked ground cable to chassis, totally rotten and oxidized, replaced that, engine started normal. Here a pic from an E34 starter just recently posted, corrosion on all terminals https://www.bimmerforums.com/forum/s...2#post30336262
of course also the solenoid could be sticcking, we disassembled the starter on an E32 750 and polisted the solenoid
