Check the basics. I don't know what testing you've done other than gas in the throttle-body. Use a gage and check proper fuel pressure and fuel injector pulse. Any applicable trouble codes? If your fully obd1 you should be able to check some codes, yourself, if the check engine lamp works. You use a jumper at the A & B terminals at the aldl. Turn key just till dash lites come on, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes. If you find a code, let us know.


Just wanted to add diagram for fuel pump. Did you check voltage and ground at fuel pump connector, engine cranking, the gray wire is voltage, black wire is ground. At the fuel pump relay, did you check for voltage at switch side of relay, use a test light, the switch side of relay is that line with arrowhead, hot all the time and fuse protected, if no voltage, did you check the fuse.

Mine was doing that Ponatic Grand AM 2002,and got a time it would not even turn over took sometime & month's with out a car was having security problem did my homework figured out that the map relay sencer needed replacement and I could not believe it she fired right and my security problem was also fixed hope this helps anything is worth a try I think.
