Not a relay. On Bosch cars it is small ignition amplifier behind the battery. about every 5 years you should take it off, clean the old thermal paste off and put on new. Also, if you have the slot head screwes hold yours in, swap them out for hex bolts.

This is one of 3-4 spare "known good" parts that anyone with an LH2.4 car should have in the car. All told the 3 parts (ignition module, AMM and fuel pump relay) cost under $100 from a PnP and can be swapped in the parking lot to verify functionality. Leave them in for a couple weeks, preferably in the summer, and then either swap back to your originals or just keep the originals as spares. you need to have known good verse new because of teh relatively high incidence of infant mortality on some new electric parts.

The fourth one is the RSR but I have not found it to be a problem again after re-soldering. A crank position sensor is a good idea as well but much more difficult to change on the side of the road just for troubleshooting.
