This weekend I was busy replacing the injectors in my 99 K2500 Suburban. Before putting on the upper intake I hand rotated the engine to TDC for #1, pulled the #1 plug and verified with a camera that it was at tdc. Put the distributor back in, got everything else put back on and nothing. It spins over but won't start. I left the distributor hold down bolt a little loose so I could potentially adjust the cam retard offset (I have an obd2 reader and Torque Pro). Since it's right up against the upper intake there's not much room to move it, but rotating it one direction would cause it to backfire through the exhaust. The opposite direction stopped the backfire but it still wouldn't start.
I've reached the limits of my mechanical abilities and before I have it towed somewhere, does anybody have any ideas? The mark on the balancer was lined up as close as possible (maybe 1/4" off) with the mark on the timing cover. Is it possible it wasn't actually at tdc and it's 180° out?
