Frist suggestion is stay away from the morons you've been getting to test it!!
As you've found out zero fuel pressure doesn't always mean a faulty pump.
The pump can't be at fault if brake cleaner gets it to run.
Get a professional diagnostic guy in.
But purely guessing from your description if it were here with me I'd be looking at the live data to see just what temperature the ECU is reading from the Coolant temperature sensor.
