96 mercury marquis wouldn't start

ignition
relay

#1

My mothers 96 Mercury Marquis would not start a couple of weeks ago and she had it towed in. The mechanic told her that he switched the wires on I think an ignition relay with another relay and it cranked up and he told her to drive it and see how it does. She drove it home and has not had a problem since but she is 82 and is determined that something has to be bad and it needs a new part so that it won’t happen again. Should we have this relay or module replaced(I am not real sure which)to comfort her and should we expect it to go out again.

Can you find out which it is, and what it is designated to do?

I think it is the ignition module but not real sure for I am 200 mile away…Motor would turn over but would never start. Is there both an ignition relay and an ignition module.

He probably switched the relay out with one for the horn or something else. There may be handful that are interchangeable under the hood. What I don’t understand it why the mechanic would not just replace the relay when he found that swapping them worked. Why not just drive it back to that shop or call them and ask?
