The method of timing verification shown in this video can be used on any car. Even on old school, non-computer controlled systems. I am also showing in this video how to properly align the timing chains on a 2003 Suzuki Aerio 2.0

Engine Performance Diagnostics chapter 1 pages 17-23

symptoms 50

  • no start with good spark, fuel and compression
  • cylinder head was repaired and timing chains replaced and now the engine will not start

fix 50

  • remove and re-align timing chain (wrong colored link was used on the main chain to align the marks)

test shown enh 50

  • how to determine the cause of a no start condition
  • how to check for spark with a basic spark tester
  • how to verify fuel is getting to the cylinder (propane test)
  • how to test for proper compression
  • how to determine perform a relative compression test
  • how to verify proper ignition timing with a scope
  • how to use an in-cylinder pressure transducer
  • how to set the timing chains properly

Tools used
