schematic shows relay in engine compartment. i am assuming it is on firewall. the only relay i see is the fuel pump.

No starter relay on this truck what is problem? hi doc. i'm not reading power at purple wire at stater solenoid. replaced ignition switch. bypassed park neutral switch reading power there.checked fuses. what am i missing? Ohm check PPL wire from P/N switch to solenoid maybe break in wire. so when key turned to start power is at P/N switch?
