i have a 3.4 camaro and i believe im having some kind of fuel divery or injector problems. when the MAP senor is plugged in the engine stalls out. the fuel pressure is 39 psi and we can keep it running by spraying fuel in the throttle body. i can start it and it will run with the map sensor unplugged . i replaced the map sensor, tps sensor, and the computer. could i have some type of injector problems. both computers do the same thing. the fuel pump seems to be running fine.it is giving a code but the car is not on the road yet and i dont want to pay the 300 or more for a code reader tool.

 

SES on? Any engine codes?

 

check for voltage on the injectors
