Need help completely lost.
OK. I have replaced every relay, every sensor with connector, fuel pump, gaskets from head up. Replaced the starter the alternator and water pump. Put in new battery and replaced all fuses. replaced fuel pump,filter and injectors. getting 39 at the shrader valve.The car will run like crap when I disconnect the maf. As soon as i plug the MAF up it doesn't start. Its almost like the fuel is being shut off. I have no vacuum leaks and used a 1990 Cadillac Deville EGR because they dont make an egr solenoid for the camaro. Any help would be much appreciated. I love my car but I really want to shoot it right now.

I'm guessing their is a good chance you have a check engine light is on? What codes do you have? Second was this issue present before you changed all that stuff or was that all done in an attempt to fix it?

Re: Need help completely lost.
I just bought the Camaro and started changing all that looked old. Im getting no codes. No it wasnt doing this before i bought it. I also found the ground diagram and made sure all of my grounds were burnished and had good contact.

Re: Need help completely lost.
You say you replaced ALL the sensors with connectors. TPS? If so, did you adjust it? Got all the relays back in their respective locations? Didn't mix up MAF burnoff and power relays? You say if you plug the MAF in your car will not start, did you replace the MAF connector? Be sure you have the wires in their correct locations for the MAF if you did change the connector. The MAF and it's wiring seem to be the culprit here so I would concentrate there first.
