TROUBLE- SHOOTING INSTRUCTIONS
If you are having trouble with your engine running badly or not running at all, first perform basic trouble-
shooting (ensure that you are using the correct parts (Table 4.1), check for faulty connections, blown fuses,
connection of VATS module, spark, timing, fuel pressure, etc.), then see if the computer has stored a
trouble code in its memory.
