I have a 1997 honda accord lx. I keep being told so many different things. Sometimes my car starts other times it doesnt. I have to turn everything off when I park the car due to My batteries not recharging right. Tapping on the solenoid while turning the ignition starts it right up. So do I need to replace the solenoid or the starter?

 

How does your battery to alternator and battery to starter look? Is your battery light on while driving? How many miles on your vehicle?

 

solenoid might just need this:

or just a cleanup.

 

That will work on the M/T cars. AT cars use the Mitsuba starter, different beasty that is a bit more elaborate to fix.

Verify the battery terminals are clean and tight.
Verify the battery is fully charged and holding a charge.
Verify the cables are installed correctly.
Verify the ground and bonding jumpers are installed clean and tight.
