Amarillo? I had to join the club and pay a buck to get a beer there with my meal! Not used to dry counties.

I am assuming you have a FSM? You have 3 different issues. 34=MAP sensor; 44 =O2 sensor and 54=Fuel pump. Were all your codes cleared when you installed the rebuilt ECM?

Sometimes the MAP sensor vac line can come loose. I tie-wrapped mine. Make sure your elec connections are tight. Or it could be a bad sensor. Wouldn't be the first time a defective part came off the shelf. Also, check all your pcv lines and connections.

A Tech-1A would help with the O2 and fuel pump volts. I have not had any problems with mine, so I have no experience with those.

Tech -1A's can be had for around $150-300 on fleabay from time to time. Be sure you get the correct modules. I havn't checked lately.
