To start the STE/ICE-R engine troubleshooting method, do the following: a. Perform GO 1 CHAIN First, perform GO 1 CHAIN to set up STE/lCE-R and check to see if it is in working order. b. Perform NO-GO CHAIN Now that STE/ICE-R is hooked up properly and checks out, perform the NO-GO CHAIN cited in the “Quick Guide to Troubleshooting.” The rules to follow when using STE/ICE-R engine troubleshooting method are: 1 Never enter in the middle of a NO-GO CHAIN. 2 Follow each instruction in a GO CHAIN. Do not skip any instructions or procedures. 3 After correcting a problem with a NO-GO CHAIN, test-run the component, engine, or powerplant to ensure the problem does not still exist.
