I have a 1986 XJ6 with a little over a 118k miles. The other day I went to work and the car was running fine, up until the moment when I had to go home that’s when she gave me trouble starting. She would start for a second and immediately shut off. When the towing service came, the driver touched the big relay under the hood located in the center portion of the firewall (underneath the upper strut tower bars) and the car fired up right away, but when he move his hand away the car died.

I checked the spark plugs, gas in the tank - even if the engine got flooded, and everything seems to be fine.

The engine is turning, but doesn't start....could it be that the relay is the cause of all this?

Thanks in advance :)

Well, have someone push it again and try and start it. If that works, it sounds like it's loose or maybe not getting good contact!

Jags have that switch for safety.That helps to shut down the engine if under the car hit to something.It looks like yours is broken and you might need to replace it.

really ...where would that switch be? Thanks

what is the name of the big relay the sits next to Diode unit, Cold start relay and Fuel pump relay, and what it does? I'm guessing that it might be it....:(

Air Flow Meters or AFMs are a "squarish" aluminum "box" with a "serial" plug-connector going to a top-mounted circuit box which comes sealed with silicone from the factory. It has a front and a rear round opening of about 2 inches in diameter. They are a very expensive unit, located and connected with bellows hoses after the air filter box, in a straight line towards the air intake. These were used in the Series 3 XJ-6 (1979½ to 1987). They control the flow of air into the engine by opening or closing a "door" or "gate".

They are repairable and/or adjustable if they go out of calibration, don't see why he needs another, and usually a used one will be worse than the one he has.

I understand the fix is as simple as replacing a small resistor which can be bought at RadioShack.

there are articles written by experts at www.jag-lovers.org regarding this component and possible fixes and testing to see if indeed it is bad.
