2 questions.......... First question to you is are you using the test port
for the high side gauge at the compressor or at the hose itself?
2nd question..... Does the A/C condenser fan come on as soon as the
compressor engages.

My guess will be you are using the ports at the hoses on the top and the fan
does not turn on when the compressor turns on. If the fan does not turn on
as soon as the compressor kicks on the high side will go extremely high, the
condenser will get very hot and in some cases the R-134 may blow out. If you
use the port at the top you will not see the high side. It has to be
connected to the compressor port. Very hard to access unless you have a
small hand/arm the grille and radiator must be loosened
