I'm assuming just by the fact you had a new battery and new starter that sometimes when you turn the key to the start position , nothing happens . Is your vehicle a automatic transmission ? When it doesn't start have checked for battery voltage at the starter solenoid S terminal ? Is there B+ voltage at pins 30 & 86 for the starter relay ? Pin 86 while cranking the engine or trying to crank the engine over . Pin 30 check with key on . Try moving gear selector to neutral . Videos on youtube for basic automotive electrical testing .

Starting System Circuit Description
Voltage is applied at all times to the ignition switch from the IGN A fuse 6 through CKT 242 (RED). When the ignition switch is turned to the START position, voltage is applied to the CRANK fuse 8 through CKT 5 (YEL). From the CRANK fuse 8, voltage is either applied to the clutch pedal position switch (M/T) or the transmission range switch (A/T) through CKT 806 (PPL). When either the clutch is disengaged (M/T) or the transmission is in park or neutral (A/T), voltage is applied to the coil of the starter relay through CKT 1035 (PPL/WHT). Since the starter relay is permanently grounded at ground G105 through CKT 150 (BLK), the starter relay energizes.
Voltage is applied at all times to the starter relay contacts from IGN A fuse 6 through CKT 242 (RED). When the starter relay energizes, the starter relay contacts close, and voltage is applied to the starter motor solenoid. Since the starter motor solenoid is permanently case grounded, the starter motor solenoid will energize two coils. The pull-in winding coil energizes in order to pull the starter motor solenoid contacts closed. When the contacts close, a plunger on the contacts causes the pull-in winding coil circuit to open. The hold-in winding coil then holds the starter motor solenoid contacts closed. Voltage is then applied to the starter motor from the battery through CKT 1 (BLK) and the closed contacts of the starter motor solenoid. Since the starter motor is also permanently case grounded, the starter motor will run until the ignition switch is moved out of the START position. When this happens, a spring in the starter motor solenoid moves the starter motor solenoid contacts and the plunger back to the rest position.
ive seen this happen on a unit that start ckt capacitor was going bad (swelled) it finnaly gave up and started no more , if unit is more than a few years old then seek a replacement as if start ckt is really at fault here then a overheat condition could result , this is not safe to just leave unattended
leave off the oven and a/c breakers and plug dryer and reset the breaker. if not tripping occurs then one at a time trip back the oven first. if no trip then trip off again and trip the a/c. if no trip then trip the oven back. if trip you may have a wire problem. if dryer trip any way then possibly you have a short in dryer. check the heating element wires,power cord at the dryer side(terminal block).
There are many different types of motors. you should have a diagram on the inside of the wiring compartment cover. This is a dayton diagram, but I can't be sure it is the same as the motor you have.Notice line terminals remain the same, but that the internal wires change terminals.
Basically, connect the incoming (line) 240 volt wires to terminals 1 and 3 and the outgoing (load) wires to terminals 2 and 4. Of course, connect the (bare or green) equipment ground wires from both cables to the "GR" terminal.
