Why 68 Chevelle won't start?

Answer 1

A number of things could cause it to not start...

Bad Coil, No fuel , bad dist, fuel pump

First thing you would do is check to see if your getting fire to the plugs...

Second if you are getting fire you then need to check for fuel..

if your getting no spark first check to see if your getting power to ur coil and dist.

if you have no power going to it you may have a loose wire bad fuse or key switch

else

if you are getting power to it your gonna wanna check the points (if you still have points)

if you do i would buy a new after market HEI DELCO or MSD dist and upgrade it and also check the coil out and go from there...

To check for fuel take the aire cleaner off the Carb and open then choke Butterfly up and look into it and move the throttle and you should see gas being sprayed into the intake if not its gonna be the Carb, Fuel pump or break in fuel line.. I boubt its the carb because the carb it will still run but not real good, It wont go from running to not, So i would Say check your Fuel pump and lines...

Hope this is some help to you and anyone else..

This should Cover All Old GM's and some Fords with Carb and points Dist.
