My Delorean stops running

[Iceguy]

Thanx Guys - I unplugged what I "think" was the 02 scensor according to Delorean03's directions, and IT WORKED. I started my car, let it run - unplugged this connection and it stayed running 30 min. I drove it up & back my street - no problems. I sure hope this was the fix. Should I worry about not having this connection or think about replacing it ?

Morpheus - It would just cut off. That is why I was thinking fuel - pump, filter, etc. But I followed what was suggested earlier and it ~seems~ to have worked.

Thank You Everyone for your help ! Know owning a Delorean, this wont be the last time I need advise. I want to learn everything about my car, and you guys are a fantastic help.

Many people run without the lambda system but if you need to pass emissions or just want the best MPG, you should fix what is broken with it. You should first test with a dwell meter if the FV is running. It should be 45 to 50 degrees or 50 to 60% if you your meter is reading duty cycle. You could also guess it works by hearing or feeling it buzzing. If that is working my guess would be the FV is hosed wrong or defective.

Can you post a photo of your hoses of the FV and where they bolt to on the FD?

The FV should still be buzzing with the O2 disconnected. Maybe your mixture is just way off.

Thank you Dave, I will be installing a rubber grommet now as part of my "holy crap this water pump replacement just got more interesting" winter downtime .

It shouldn't need one. The grommet is part of the connector. From inside the car just push it back in place.

Dave - I'm not understanding - FV ? FD ?

Sorry.

FV = Frequency Valve. on passenger side valve cover.

FD = Fuel Distributor. The round black thing with all your fuel hoses going to it.

I was looking for the drawing of the fuel hose routing but could not find it. It was done very nicely on the old forum. Your hoses look pretty clean and probably are attached correctly.

When you get time, pull the air cleaner off and you will see the FV. If you touch the FV with a wooden dowel or a large screw driver then touch your ear with the end of dowel (use your hand as a pad for you ear). It works just like a stethoscope. You should hear the FV buzzing when your engine is running. That trick works good to find other problems with engines like a bad bearing.

The hoses were redone by the previous owner, I found the bill in the glovebox. I will try the trick with the FV tomorrow.
