Long story but detailed to assist proper diagnosis. Noisey harmonic balancer was replaced at local shop with correct new balancer, key was messed up, shop said he had to remove timing cover to replace messed up key. Both sensors replaced, new timing chain, since we were in the same area and car has 102,000, all was replaced, vehicle ran for about 25 miles and quit. Went back to shop, said not his problem. Had other shop look at vechicle, went to start vehicle and gm code 58 came up, tested key key was within spec's, tested wires at base of sterring column, same ohm reading within.03 and said that little bit of difference should not matter. Shop is stumpped, he said he can read rpm, fuel pressure, spark, injectors reading okay, but not releasing fuel into combustion chambers, he said the vehicle thinks it is been stolen, he has tried to trick the system using resistors to change the.03 ohm difference. Is there something we are not looking at? Missing something? Please help!

Getting good fuel pressure, injectors are pulsing, I did take afew spark plugs out and they are clean not fouled, and cannot smell any fuel in cylinders.
