1992 S10 Blazer 4x4, 4.3 V6 vin Z (TBI), auto, AC, etc. 104,000 miles...
Okay, here's where I'm at. My Blazer won't start, and it hasn't in roughly 5 months now. I need this problem fixed so as not to incarcerate myself. I've been through the standard troubleshooting (fuel, air, spark, all of which is satisfactory) and my truck still doesn't start. In turns over like normal but it won't fire. Not even with starting fluid, it won't sputter/kick or anything. At the moment I'm think timing chain, but I don't hear (nor have I ever) any sounds to suggest a busted timing chain. I don't imagine that would go silent. By the way, I've recently replaced the entire ignition system (minus distributor itself), fuel pump, water pump, alternator, oil pressure switch, TPS, etc, etc.
WTF am I missing?! This is killing me.
