hope this helps me I'm working on a 69 mach 1 just put a new wiring harness in from firewall out, when i turn the key to "on" position it tries to crank....someone has been doing some "homemade" wiring on the car so who knows what I'll get into. any comments and/or suggestions would be a help. Car was wrecked on the right front real bad, had to replace from right lower firewall out and rails on both sides, new aprons and rad support.

Chris can you be more specific what do you mean it trys to crank? it clicks or it turns over dont start?If it just clicks coul be ground or solenoid maybe.Turns not start possibly no spark.possible wires to coil,distributor,maybe from ignition switch.need a little more info.
If the engine is cranking, i.e. the cooling fan is turning when you turn the ignition key, fuel can be an issue too besides getting a spark. These old cars do not have electric fuel pumps and are harder to start. You usually need to pump the gas pedal several times to get the gas flowing. Make sure the automatic choke on the carb is closed too. Good luck.
Yes - rats, mice and various other critters can certainly put the hurt on car wiring. I bought a parts car that had the carb full of dirt from field mice and they had eaten all wires including the plug wires.
