Not positive but I wonder how good the fuel pump is since it was a roller. Maybe check your fuel psi?

The guys I bought the car from put a new pump in it to get it running. Then used the motor for a blower car. So as far ass I know the pump is new. but i have not checked the fuel pressure. and dont have the tools to do so.

You need to figure out why you cannot pull codes. That's the place to start.

If the sensor you're talking about is to the driver's side of the dizzy and has one wire on it, it's the temp sender for your gauge.

all the plug wires in the right area? where is timing set? have you figured out why you cant pull codes? have you gone through the surging idle checklist? It helped me a great deal when I was trying to fix my car.

SD system? Check the readings of the MAP sensor. It could be a bad O2 or exhaust leak as well but I really doubt it. Definatly check the MAP

Sounds like you put the SD Computer into a Mass air car. I don't think that works.....

I know you got another ECU, but what was the code? Ideally you'll want an A9L code. There are others that work.
