Honda Civic 1.7L starts, runs, stalls (incorrect timing belt installation)
Conventional wisdom tells us to check for spark, fuel and compression during no start diagnostics. Where do you go when you have all three? This video explores multiple ways to test for ignition and valve timing issues, and how you can be confident in your call before spending labor time on tear down/inspection.
