Fc electrical problems
 

Iv recently bought a 1988 FC Rx7 convertible but I haven’t been able to get it to run. It has spark and compression but I know it’s not getting fuel, (fuel injectors aren’t firing). I replaced main relay but even new I don’t feel it click/ activate when key is in ON position, my guess is the relay isn’t getting its 12v? After a few seconds of it on I hear an electronic siren could it be an anti theft system that’s cutting power?

How have you checked if the fuel injectors aren’t firing? Are you sure that they aren’t just seized as I had the same issue buying a car that sat for a while, I let them swim in diesel for about a week and that cured that.

also what do you mean by a siren? Like the horn?
