The car starts and runs fine for like 10-15 minutes then dies it will start one more time with a little miss then wont start at all unless I floor it to keep it going then stron smell of gas. I changet coil pack fuel pump fuel filter fuel injection regulator and O2 sensor no service engine soon light is on but I manually checked for a possible code and it doesnt show one. I'm lost now and just cant figure it out

Sorry I just saw this yes I rented the tester and the pressure was within specs and even though it was I figured since it was a 1992 and most everything was original things were getting tired so to speak thats why I really had no problem changing the fuel pump, strainer, filter, and fuel injection pressure regulator

Check the idle air control valve, TPS and MAP sensors and clean out the throttle body-let me know what you find

Ok I checked all the components mentioned the idle air control valve had a lot of soot on it it had movement but im not sure how much movement it is supposed to have though and with all the sensors I dont know how to check them with a multimeter so all I can tell you or give you is visual information the map sensor had some soot on it but the platinum wires were in tact and the TPS moved freely

Clean out the PCV and EGR valves-The IACV you probably have to change it-
