The 95 GMC 1500 V6 automatic transmission may not be compatible with the 89 K1500 V8 4x4 due to differences in engine size and drivetrain. It's recommended to use a transmission that matches the engine and drivetrain specifications of your 89 K1500.
Is the purple wire at the starter solenoid showing power when the key is turned to the start position? Check that first. Also do you have an aftermarket starter interrupt system, look under the dash for a little black plastic case with wires coming out hanging down or taped up there.
Spark plugs are set at 0.035 inch.
Ignition timing is set at 0 degrees BTDC. The computer then controls the timing from there. There will be a wire that you unplug before you set the timing, then once you have verified that the timing is at 0 degrees, then reconnect the wire and you're done.
Check Battery voltage
