My '92 deville fails to start after the first 2

Next time you have the problem check the fuel pressure, bet you have none. The fuel pump is electric and located in the fuel tank. These fuel pumps last on average about 100,000 miles, less if you run the tank lower than 1/8 due to the overheating it causes the fuel pump due to the loss of lubrication and cooling from the fuel it sits in.

How do I check vacuum system for 92 Cadillac devill climate control system?

This problem is most often caused by the air mixing valve (usually its actuator has stopped working - fails in the cold position) so I would start there. Not sure about a 92 - could either be an electrically or vacuum controlled actuator. You can check vacuum at the HVAC control unit with a vacuum tester.

What does the eror code e30 means

Code 30 means the idle speed control RPM is out of range.
The computer can not keep the idle speed in the correct range.
Could be the control servo, a wiring problem, or something like a vac leak.

take the alternator to an accredited auto electrician for a bench test
