1990 GP SE model starts then dies
my 1990 pontiac grand prix SE model has a nonturbo 3.1 v6.
it will start just fine, and idle, but when i rev it up, soon it will cut out and die. i will try to press the gas pedal to keep it going, but it does nothing.
i have had a code for a MAP sensor and CRANK sensor, and i did replace those sensors. changed all spark plugs and wires, and i have a new airtex fuel pump and i bought a filter this spring.
i have spark as tested with a spark tester, and 42 PSI at the fuel rail which is in specs according to the CHILTON manual.
i have guessed before that it could be a oil sender switch, and i tried hot wiring the fuel pump to a toggle switch bypassing the oil pressure switch, and running it manually. it still dies....
please help thanks
