Re: 1993 indy 500-- only starts when its been running



so did i kill anything when i hooked the battery hooked up backwards?
i heard a buzzing sound i figured that was just a warning of some
kind. but yes when the sleds cold it dont run at all and when i leave
it sit to long it also doesnt work. but when it does warm up it runs
fanaminal. theres silicon greese on the ecu plugs already but i will
put greese on all other connections.
