Where is the main relay located in 1992 MPV ? Engine cranks, but won't start. Was getting no fuel to injectors tubing manifold. As learned, electrically jumped the fuel pump at yellow test connector and fuel is pumping. No spark delivered to by coil. Have been told problem may be a bad main relay. Answer to relay location or other troubleshooting suggestion welcome. " Gracias "

 

I don't know if this helps, the info is from a very iffy Haynes manual. It shows a "Circuit opening relay" mounted on the left side of the electronic box under the front of the p-side carpet. No other info on what it does, but it's the only one that isn't obvious in it's purpose. Though I think it might be the impact cutoff for the fuel, I remember checking it when I had a fuel pump issue.
The main EGI relay is in the black box between the coil and fender, d-side under hood. A/C, antilock, and horn are there too.
Hope that helps. Most of what I know about mine(91),I learned the hard way. Haynes books are woefully inadequate. And often inaccurate.
PM if I can help further.
