Battery, alternator, cap, rotor and starter all replaced in past 6 months. Plugs and wires about 1 year old.
Engine tries to turn over but sounds like not enough juice to do the job. No clicking, just a really weak crank. Headlights, stereo and dome light all come on fine. I haven't lost the presets on my radio. With the head lights off, when I crank it the headlights start to come on. (???) I tried jumping it but didn't make any difference. I disconnected the cables at the battery and inspected/cleaned the terminals. There were no signs of corrosion. I checked the cables and didn't see any tears or cracks.
There was no warning. It's been starting fine. I drive it almost every day. I went out the other night and it wouldn't start.
TIA for any help.
