Thanks to 93MBS, MegaMax and all of the incredibly helpful members!

I parked my 1993 SC300 in the garage one night and the next morning it would not start. It tried to run once and it continued to turn over nicely but it would not catch.

After checking the obvious, then replacing the ECU ...drum roll...it turned out the timing belt had slipped! Now, this is a new high end timing belt and there really is no excuse but that is what happened.

I did not need the new MAF, ECU. I returned the NOID injector test lights. However, the timing is spot on, the valve clearance is perfect, the fuel has never been cleaner or the octane higher, and the platinum plugs, high tension wires, distributor cap, rotor, PCV, etc. did not go to waste. I am outta the garage!

Kind regards,
Wade

 

The timing belt slipped? Any idea how the car managed that

 

Put this same info in your original thread so it doesn't end up like 99.9999% of the others out there that just end suddenly with no resolution reported.

It never fails that when searching for a fix, you'll find threads that describe your exact issue and every damn thread will just end abruptly with no resolution reported. Sometimes they'll tease a little further by making a post that says simply "FIXED" with no elaboration. These infuriating threads exist on every message board in the world and you're sure to find them right when you need a fix the most!

 

I like the high tension wires Glad it's fixed sir.

 

It's always a good feeling when you fix something after several hours of troubleshooting. I know that feeling from experience. Believe me.

 

My best guess is it happened when I tried to start it. It cranked at first like the battery was slightly low (just not enough juice to spin the engine convincingly) then it was like something broke loose and it cranked fast but would not start up.

I suppose it could have happened over time. Since I will be pulling the cover and checking the timing marks on the gears at TDC weekly for the next month, I may have a better idea later.

The timing belt was from the stealer and had fewer than 5k miles on it. I installed it myself.
