[s-cars] '92 won't start

[Michael Wakefield]

If they drove it off the truck, they may have forgotten to plug in the CPS sensor when replacing the hose. You would think that if the heat or coolant was going to damage something, it would happen while the motor was hot and wet, not after it had cooled down and somewhat dried off. If they have actually tested for a signal from the crank sensor and found none, then that should be it, but that sensor is NOT behind the timing belt!

My wild guess is that it's either a bad CPS, due to becoming pretty hot from the ordeal, or else the shop damaged or unplugged something when they replaced the turbo coolant return hose, which is really hard to access. I just replaced a CPS, and it's actually not a bad job at all. You only need to pull the cam drive pulley off, and it easy from there. I aligned all the timing marks, marked the timing belt, pulled off the cam pulley, replaced the CPS, replaced the pulley, and then slid the belt back on. All the alignment marks still lined up, and all was good. The crank sensor is pretty robust, and I'd be surprised if it's the culprit. I would suspect the CPS, and wouldn't change the belt, unless it obviously damaged.
FWIW,

Unfortunately, the leak got worse and not wanting to blow the head gasket or warp the head, I had the car towed to a nearby garage (otherwise it would have been $250 to tow it home).

They said it's behind the timing belt so they'd need to take all of that off to replace the sensor.  While they're at it, they'd do a timing belt job.  Total cost is about $1500.  I said I'd think about it and get back to them.
