Bad switch or wrong one. The '75 I'm working on has 4 positions: 1)lock,
2) off, 3) ignition on, and 4) start. Could it be that you have one with
too many or too few positions?

Subject: new key switch, now won't start
About a week ago, the key switch in my 1974 MGB got stuck in the 3rd
position, which is the cranking one. I could remove the key, but not
things off. This happened after the engine had started, so I ended up

I ordered a new key switch from the Roadster Factory and was told over
phone that the new switch would not have a plug on the end of the wires
that I would have to use the plug off the old switch. This wasn't the

installed the switch in place of the old one, plugged everything in and
prepared to start the car.
It cranks, but won't fire. I remembered to fasten my seatbelt but that
no difference. It's getting fuel as I can smell the unburned fuel coming
of the exhaust after a brief time of cranking with the choke on. I
have time to check the spark, but will tomorrow if this keeps up. The
leads are on correctly. Nothing appears to be unhooked. What am I
As always, any help would be appreciated.
