What do i need to do if my car wont turn on after replacing my old radiator.

it wont crank. I can hear the fans on the radiator start running but thats about it. Before it broke i had changed the clutch and everything was fine.

have you checked the Clutch Pedal Safety Switch?

yes i have.. all u can hear when you turn the key is the fan and a clicking noise which is where theres a brake fluid resevoir.

get a volt meter and a helper.put the meter on DC VOLTS SCALE.have the helper turn the key to the cranking position while you check the small wire on the starter for battery voltage.if no battery voltage,the ignition switch is bad(electrical part,not key switch).if battery voltage at starter when trying to crank it,then the starter is bad.check all of your work that you did before this problem started also.see what happens...

Thanks i will try as soon as i can.

ok...you can actually pull the small wire out of where it clips in/on the starter to test if there is voltage on it while helper tries to crank it.red lead to the small wire,black lead to a GOOD GROUND close by,should have battery voltage=12.6 volts is a fully charged battery.as a matter of fact,check the battery voltage FIRST,on the battery terminals.Note>12.0 volts on the battery is 75% discharged.and i guess i should have ask you sooner,have you tried rolling it off and or jump starting from another vehicle?..also,have you replaced the stupid main relay that goes bad due to a cold solder joint inside of the relay on the circuit board?this causes a crank no start condition that usually happens in the HOT MONTHS?this happens on about all acura/honda 90's and up.

I finally found what it was. The ground wire wasnt well connected. Thanks for the help

good find...i have had folks tell me a ground does not matter!.........LATER
