Lexus SC 400 Sensor Problem
Replaced water pump. Car started but missed so hired mechanic to retime it now I have 12 volts to back side of distibotor but none to plug wires. Replaced rotors but no help. Took crank sensor to mechanic and he said testing ohms showed shoule be ok. Crank and cam sensors at least $80 apiece so can't just replace if not the problem. Thank you for your help.

i would start with basics.
compression test as it is an interference motor.
fuel pressure and spark.
do not throw parts at it till you know the failure

Compression was btween 180 to240 cranking for 10 to 15 seconds. Problem is I have no spark but do have voltage at the back side of distributor

then you may have a failed distributor assembly

Is it possible for both sides,to fail at the,same time since I have no spark on either

Check the crank sensor wiring an ensure the reluctor at crank sprocket is installed correctly.
