Where is this fuse located?
I have an 89 IROC and need to know where the 20 amp inline fuse for the fuel pump relay, fuel pump/oil pressure switch, mass air flow relay, and the burn off relay is located. The wiring diagram I have says that it is suppose to be hot at all times, and I do not have any power to any of these relays.

Not sure if it's the one you seek, but there is a 20amp fuse in the passenger well, under hood, kinda gets tucked behind battery - try that.

I'm not sure if there was a change but off the battery was a fusible link to the oil pressure switch for my '83 CFI Z28.It was crushed while working and once she was back together got no fuel from the injectors.Tracing the wiring gave me this and repaired it and fixed the problem.

On an 89, I'd say in the default battery location. It's usually attached to the fenderwell and looks like an unused connector so it can look very deceiving.
