Im betting the used CPS you put in is garbage

Disconnected and reconnected computer, starting to replace all the sensors one at a time on the intake. Anything else I should try?

Yes. Test the CPS you put in it.

The CPS is good I took it out of a running jeep, even put mine in the other jeep and it started right up. I found a ECM for $97 I just ordered it.

I did unhook the computer and spray it out with dielectric cleaner and nothing. It was on the drivers side under the hood. So in a few days I'll hook the new one up and I expect everything will be fine.

I know the CPS is good, and I'm still getting no bus. I cleaned all the connections under the steering wheel where the OB2 hooks in, even unbolted the connector and cleaned it, checked all fuses, and since I still get no bus it's the computer. Everything is grounded also.

Hey I'm still having this problem. I've replaced the ECM and it still won't start. The Fuel Pump fuse is getting power checked it with a voltmeter, about to check the pump. My only question is if the fuel pump is bad would it cause a no bus?
