I purchased the tool to perform a compression test. The procedure is pretty simple, especially with the 12v trigger attached to pins 11 and 14. I removed the main relay, fuel pump relay and lead to the ignition coil. I cranked the engine until the compression was stable.
These are the readings I measured:
Cylinder #1: 160 psi
Cylinder #2: 182 psi
Cylinder #3: 177 psi
Cylinder #4: 155 psi
Cylinder #5: 176 psi
Cylinder #6: 174 psi
