Having problems with your Chevrolet 1500 ?

I have a 1992 k 1500 the spark advance is not working i have replaced the MAP, electronic spark control, tps, distributor, checked for vacuum leaks. its also not throwing a code when you disconect the blk/tan wire for for timing (static). i am under the impression that it is either a bad wire or the computer if you could tell me what wires to check, and if or how i could tell its the computer that would be much help

I would check the Knock sensor. It should be on the drivers side of the engine just above the line of the oil pan and to the rear of the motor mount. A parts store can test it for you. Lee
