IMS relay?

Oct 28, 2003 4 Replies

I found a relay under my dash the the previous owner of my Bronco had cut two of the three wires off of. It says on a white sticker on the relay "IMS". WHat is this, what does it do, and could it be contributing to the problem of every once in a while my truck dying and not starting again for a while? Thanks in advance for the replies.

Might it be the seat belt, ignition, headlight warning alarm?

On the late 80's Broncos, it was an "Inferred Mileage Sensor". Supposedly all it did was turn on an idiot light to take it to the dealer, probably like the Hondas had for maintenance checks. You might find it in a Chilton's at the library if you don't own one. Tom F.

Why would anyone waste their time on Chilton's, when you have Helms and Ford available?

Supposedly

probably

If they're also available at the local library, fine, use them. I've used Chilton's manuals on a lot of my older cars with no problems, and very few questions. The newer manuals ( late 90's to present) don't seem to go into near the depth the old ones did. First one I had was for a 64 Ford Galaxy

500, and fixed every problem I ever had with the car by looking in the manual. Rebuilt the engine and the tranny with the same manual- no problem. I've seen the recent thread against Chilton's and Haynes, but they used to be fine reference books. Like most of the newer cars and trucks, they've gotten cheaper (in quality, not in price) over the years.
