My car won’t start and lights and everything come on and just won’t start for me I tried everything what can I do
Will it start with a jump? Your battery may have enough power for the lights but not enough for the starter motor.
Have you tried starting it with the transmission in neutral?
Does it crank? (i.e. turn over) ?? Or cranks but just won’t start?
Without the answers to the questions above, you are not going to get anything but guesses. And some of them may be expensive.
Battery cables loose
Engine locked up
One thing to check on your vintage GM vehicle is the positive battery cable for corrosion.
