For the first time ever, the car will crank well but not start. No preexisting operating problems or starting problems cold or hot.

We have spark to the front 3 plugs. There was fuel in the cylinders/plugs. Fuel pressure jumps to 60 when ignition is on and then drops to about 30. When you crank it it jumps up to the high 50's. Starter fluid did not help start it. Any ideas on what to check?

It is fine. Do you have a series of tests I should go thru? Do you know the specs for the fuel pressure when starting and running? thanks Joe

Thanks. As expected, that confirms that the readings I provided are within the acceptable range. Do you have a series of tests that should be followed to locate the source of trouble? thanks Joe

Check the fuel pressure before and after the fuel filter, also check it with and w/o the fuel pressure regulator and also check if the injectors are pulsing

Changed the fuel filter. If the pressure readings are within your specs, as they appear to be, doesn't that rule out a fuel problem and most likely point to an electrical problem?

If its getting spark and correct fuel pressure- check if the injectors are pulsing if okay-check engine compression-
