56 Buick Posted July 20, 2018 Share Posted July 20, 2018 Hi all So the car will start in drive and reverse and I assume this should not be the case? Anyone have any idea what is likely culprit and how to fix this? I not the car has had an ignition kill switch fitted. Any help would be much appreciated.

SpecialEducation Posted July 20, 2018 Share Posted July 20, 2018 Ours does, but the pedal start was defeated long before we got it... Whoever put the button in bypassed everything factory. Link to comment Share on other sites More sharing options...
lancemb Posted July 20, 2018 Share Posted July 20, 2018 No it should not. Your neutral safety switch on the steering column underneath should prevent this. I recommend getting it replaced or wired correctly. 2 Link to comment Share on other sites More sharing options...
Rztrike Posted July 20, 2018 Share Posted July 20, 2018 Mine is all original. No it shouldn't . I agree with lancemb 2 Link to comment Share on other sites More sharing options...
56 Buick Posted July 20, 2018 Author Share Posted July 20, 2018 Thanks. Do you know if the neutral safety switch location and troubleshooting is in the shop manual? Link to comment Share on other sites More sharing options...
old-tank Posted July 20, 2018 Share Posted July 20, 2018 The combination neutral safety switch / backup lite switch should be on top of the steering column between the dash and firewall; not much goes wrong with those switches and starting in all gears is impossible (switch failure is a non-contact condition) The wiring diagram in the service manual will be a big help to show how it is "supposed to go". When someone "messes with" the starter wiring they usually jump 12v+ to the solenoid by way of a push button (that bypasses the safety switch). 3 1 Link to comment Share on other sites More sharing options...

My reverse lights work so it is likely the switch is working and just been bypassed, noting the ignition kill switch that has been put in also bypasses the need to use the accelerator pedal. Now I am not that technical with electrical but I should be able to correct this issue by either rerouting the 12V+ line to the neutral/park switch before it goes to the kill switch OR rerouting the line from the kill switch to the solenoid to include the neutral/park switch.

56 Buick Posted July 28, 2018 Author Share Posted July 28, 2018 After some review I see the starter relay has been removed (no longer there). The pink wire from the accelerator switch is not connected to anything. The light green wire coming from the generator terminal of the generator regulator is not connected. And the kill switch is connected to directly to the ignition key switch and the solenoid the cranking motor. I am going to have to get another relay. 1 1 Link to comment Share on other sites More sharing options...
old-tank Posted July 28, 2018 Share Posted July 28, 2018 Here is your relay: https://www.ebay.com/itm/56-1694-STARTER-RELAY-NEUTRAL-SWITCH-RELAY-fits-1958-1961-CORVETTE-New-Vintage/122143879651?hash=item1c7057b1e3%3Ag%3AvoYAAOSwAvJXBSM7&_sacat=0&_nkw=Carquest+56-1694&_from=R40&rt=nc&_trksid=m570.l1313 That Carquest 56-1694 is correct for many Buicks like yours. 1 Link to comment Share on other sites More sharing options...
