Please help troubleshoot my 1MZ-FE V6 engine not starting. What would be the likely causes and next troubleshooting steps for the symptoms described below.
Engine was running well on the interstate this morning until dash lights came on and gradual loss of power, then complete stop. Lower radiator hose was leaking near clamp and the radiator was half empty. I do not believe the radiator temperature gauge rose significantly before the failure.
Got a tow 100 miles back to the house then tested the battery. The battery was dead so I charged it. Still would not start. I put the transmission in neutral gear and turned the crank pulley with a wrench. The belts and pulleys appear to be rotating normally. I got someone to turn the ignition key while I watched the passenger side of the engine. The accessory belt and pulleys appear to be rotating normally. I can't see the timing belt yet. I think this is good news because I was concerned that the engine was seized but now believe it is not seized.
The battery, starter, alternator and serpentine belt are only a few months old. A new water pump and timing belt were installed 50,000 miles ago. The car has about 210,000 miles now.
What would be the likely causes and next troubleshooting steps for the symptoms? Thanks!
