1999 chevy, sub, k1500 (1/2 ton, 4x4) Engine code: R, 5.7 L
Drivers side head removed, valve bent, replaced at machine shop. Rocker arms adjusted per book; at TDC + 5-10 degrees in power stroke position. Intake manifold sealed/RTV (back and front) provided with intake gaskets.
Engine won't run; it runs for 2 seconds after I turn ign. Key toward the "off' position. Won't keep runing even if held between "start" and "off". The last attempt caused backfire through the carb.
New crankshaft position sensor, new distributor; very carefull (3 times) to check no. 1 cylinder in fire position and plug wire locations. Before valve repair mechanic/computer set timing. We noted that the distributor had to be rotated to it's extreme position to get within 1 degree. The engine won't start in that position; no spark. (Orig position was in center).
No "service engine soon" codes. Cleared anyway.
