Cranks But Wont Start
2002 L300 V6 3.0
Replaced fule pump - Sending Unit - and Fuel filter when i got the car -
I was driving home from my Girlfriends house and the car shut off. powered down while driving. Put the car in park turned the key back from ON to ACC Tried to start the car and it would not turn over. The car cranks but wont turn over. Had the car Towed home
Car cranks but wont turn over.
Ran an OBD2 on it - Vacuum Leak - O2 Sensor - Crankshaft Positioning Sensor -
Replaced the Crankshaft Positioning Sensor - Easiest repair i have ever done on the car. -
Still wont Start-
Opened throttle body and shot ether in to it...wont even start.
Thinking there is no spark - Or Electrical Issue - IM AT A LOSS
PRIOR to the car dying there was a clicking noise at the Gear selector area - I thought this was the NEUTRAL SAFTEY SWITCH OR a Relay that was going bad - when the click of the relay or sensor would happen the Thermostat Gauge would loose pressure - It would drop and then come right back
The car sat for a month and did get a mouse in it. Nest was present when i opened the hood - seeing poop on the engine but cant find more signs now. - After finding the mouse i drove for 2 months and then it sat for a week again.
i have checked the fuel pump relay and the fuel fuse. There is Fuel coming to the Fuel rail coming out of the Schrader valve -
Could the Vacuum leak cause the car not to turn over?
Any one have any experience with this mystery sensor?
if the car jumped timing and BROKE the engine would it still crank?
Is there an anti theft sensor that may have gone bad and caused the ECU to shut off spark or fuel?
Could the injector "Pump" have gone bad...i don't even know if thats a real thing.
PLEASE HELP in any way that you can. Thank you Community.

Re: Cranks But Wont Start
When was the timing belt last replaced and what is the current mileage?
Does the sound quality of the engine cranking remain the same as before this event or not? (If not then a compression test might be in order.)
Perhaps there are some damaged wires due to the rodent infestation that are hidden from your view.
298,000 miles-it keeps on rolling!
The blessings of liberty erode in my country.
Gov't's grown bigger, but a chance exists that it will be reduced. I'm cautiously hopeful.

Re: Cranks But Wont Start
Humble2002L300, in addition to questions asked, did you check for blown fuses? Main fuses are in the engine bay, two more in each foot well (driver and passenger). Is the security indicator flashing quickly during starting or off. GMs Passlock anti theft system disables injector operation when security is flashing. When enabled and armed via remote, security blinks slowly (car with an oversize padlock symbol).
Presuming ether was sprayed and the engine refuses to fire up suggests ignition system (no spark) issues. It would be unusual for both coil packs to fail, possibly pointing to fuse(s).
