We've replaced the battery and the ignition switch. Alternater and starter all good. We turn the key and still will not start, no noise, no nothing. also notice a fuse missing in the IPM box. Could that be the problem?

Re: replaced ignition switch, still won't start
Starter relay switch might be a problem check if the fuse box under hood has one! and fuels may look okay with the eye but you should invest in a circuit tester also if wires are in staled incorrectly on the starter this can cause it to play dead also be careful you don't short that electrical out that can be very smokey.well hope my info has helped you out good luck merry christmas.John

The PATS security system would prevent the engine from cranking if the system does not "see" the right chip in your key. If the system is working correctly, the light should go off after you turn the key switch on. You should have power on the small starter wire when the key switch is in the start position.
It sounds like a fault in the starter circuit. It could be a defective neutral safety switch, starter solenoid, or possible a defective ignition switch but I doubt it. Can you hear the starter solenoid??? I'm willing to bet the problem is either with starter relay, neutral safety switch, or starter solenoid.
Hi, if the car engine fails to crank, there is a fault in one of the components in the battery/ignition/starter circuit. Low battery (Check battery voltage, recharge if low, or jump start with another vehicle or battery charger). Bad starter relay/solenoid (Check for
voltage at relay, if relay has voltage but there is no "click" when key
is turned to start, replace relay). Bad ignition switch (Check to see if
voltage reaches starter relay/solenoid when turn to start. If not,
check for open P/N switch and brake or clutch pedal switch. Replace
ignition switch if defective).
1st check the main cable to the starter make sure it is clean and tight, disconnect battery first, after that there should be a small wire going to the starter jump that small connector to the main battery cable on the starter (IGNITION OFF) if it cranks you have a wiring or ignition switch problem if not Starter time just make sure you get a very good quality starter some cheap and even lifetime starters are so poorly made that even after you replace them you still have a problem only a bad noise coming from the new starter you just put in.
your starter is bad.... the two contacts inside the solinoid are worn out only way to fix is replace the unit as a whole bet ya you get click click click then my start.. bet my life on this one been fixin toyotas for 20+ years
