Greetings DD,

Do a search on vacuum shut off valve and vacuum shut off valve and you should bring up my lengthy thread on what and where to test your shut off vacuum switch on the key switch. I believe this to be either leaking air or seaping enough to cause your problems for shut off and vac locks. I would also look at your ignition switch and see if it is dripping oil, if so please repost asap with problem.

Thanks,


Charles
