Whats up guys, Not only new to the forum but new chev owner. After hrs of browsing on al gores superhighway and getting mixed results, I decided to go straight to the source.
So here's the deal. I bought a 97 Tahoe w/Vortec off an older vet it had been sitting for 3 yrs Brake lines and fuel lines rotted through. Got all of that sorted out she started and ran GREAT! I was impressed at 207k on it. Anyway, its been raining for like 4 days here I've been cooped up so I decided to do a spark plug change (didn't start it prior) and now its a no start?
>Heres what I've got. It has solid spark all the way to the plugs Coil and Ignition module tested _within spec_ grounds tested and cleaned, cap and rotor -ok. Fuel is within psi range and leak down test meets tolerances. so fuel and spark but no bang hu, All I can think of (or read on the matter) is that the injectors are pulsing at the wrong time and or the cap has built up moisture energizing the air and creating a misfire. so all I have left is the Hall effects sensor or whatever GM calls it (CPM) in the dist. or the Crank sensor I can't think of anything else guys.
------And noooo codes
