Answers :

I'D START BY CHECKING FOR ANY VACCUM LEAKS NEAR AND ABOUT THE INTAKE MANIFOLD. IF IN FACT YOU DO HAVE AN 88 IT SHOULDNT BE CARBUREATED IT SHOULD BE FUEL INJECTED. IF SO YOU NEED MORE THAN 45PSI OF FUEL PRESSURE TO MAKE IT RUN RIGHT. TURN ON THE KEY BUT DO NOT START THE ENGINE. LISTEN AND SEE IF YOU CAN HEAR THE FUEL PUMP CHARGE THE SYSTEM, SHOULD BE A LIGHT HISSING SOUND. IF SO START THE ENGINE. WHEN IT SHUTS OFF THEN TURN OFF THE KEY AND REPEAT THIS PROCESS AGAIN, IF YOU CANT HEAR THE NOISE AND IT WILL NOT CRANK THEN EITHER YOU MAY HAVE A FAULTY FUEL PUMP THAT IS ONLY WORKING INTERMITTENLY DUE TO BAD PUMP BRUSHES (REPLACE FUEL PUMP) OR YOU HAVE A BAD FUEL PUMP RELAY.
