intermittent no start till you cycle the gear shift

[Prius454]

helping my buddy with his 90 c1500 350 . i was looking into his gear shift issues . the column shifter has to be pushed hard into park to take out the key , also needed the e8 bolts in the column tightened . so while i was in there we did the blinker and blinker cam . and now the intermittent no start is worse . if it does start i need to cycle the gear shift all the way down to low one and back up again to park and try and start it . i took out the neutral safety switch . cleaned it and then jumped it still there, replaced the fused link under the engine bay cover because it was corroded and the issue is still there . is this the ignition switch ?

Its almost always the neutral safety switch. Needs adjusted or its falling apart inside, but your said you jumped it so maybe your ignition switch? Doesn't sound right with the shifting you describe.

But: Have you inspected all shifter linkage and any bushings, for slop?

I'm with movietvet, linkage bent/adjustment/worn, especially since you have to push on shifter to get key out . Or could linkage be installed half out at transmission ?
