I have a 1989 Buick regal. It ran like a champ for months but then outta the blue it's started given us what we thought was either idling problems or fuel issues. We have replaced the map sensor, erg valve, aic sensor, fuel filter and pump, starter, spark plugs n coil pack wires, tps, half a tank of gas and still have no starting or even running car. I'm at my wits end and I'm a female with very lil machinacial skills and ability... Now I heard that it may b are netural safety switch. Does n e one know bout this switch n what it does when it goes out and warning signs if any... Has anyone else had this or something similar happen to them?
I don"t have an answer, but am having the same problem with an 89 Regal! Have you had any luck?
