I have an 1898 Buick regal n I can't get it to start or run. I replaced the starter, spark plugs, wires and cables, map sensor, fuel pump n filter, erg and aic valve, tps and coil packs. Still wont stat and I got no mechanical know how to keep going. Sometimes it clicks when I start it, other times it does nothing. Was told it could be the neutral safety switch. Ghost has been going on since Jan and been in the garage this whole time. Please contact me at firstname.lastname@example.org with ANY advice. Thank you and face a good day!
