Bad ECM

PO 1361 ignition control circuit low voltage. Check your ignition module and coil.

future reference brake cleaner isn't good to use on mass air. use mass air sensor cleaner or electical cleaner

The computer runs the Transmission from the signals the throttle position sensor, crank shaft sensor, and cam shaft sensor. Your going to have to replace the transmission with an older transmission like the turbo 350 or turbo 400. When it's time to get the car e-tested, that's when your going to run in to problems, due to the year your Chevy is. If your Chevy was a 1985 then you could go with the carb system but with being the newer OBD11 system, your going to have an off road only vehicle with that swap. Why would you want to replace the engine with the 350 carb set up??? There are things you can do to tweak the one in your Chevy free of charge.

Yea as long as they are both manual transmissions everything will bolt up the same.If you use your old transfer case you will still have push button.

Yep that is what the code is for. Make sure the passage is clean after you pull it off.

Had the same problem with my '96 Silverado with 350 Vortec. The truck would only crank. It would start if fuel was poured down the throttle body. Could not hear the fuel pump hum. Fuse was good, but could not hear relay click. Relay was good, Did some electrical wiring trouble shooting. Turned out that one of the connectors that clasp onto one of the pins of the fuel pump relay wasn't making a good connection, too loose. I just stuck a peice of wire into the connector and pushed the relay back in. Relay clicked, Truck Started. It's been more than 4 yrs. since I made that McGuyver fix. Still firing.
