Don't know what two wires were not connected, but I'm guessing that, if it's the oil pressure sender, one of them is 12V. If that was connected to the wrong place, you probably blew the fuel pump fuse.
As I slipped a disc, I had to wait for our son to come by and crawl in there to check/replace the fuse. Just as Raydar said, second one from the left in the top row, it was blown.
Inserted a new 10 A fuse and she started right up. Thanks Steve!
But I must admit, some things are coming back to me now. Considering, I hadn't touched a Fiero in almost 6 years. For one thing, I should have known to check fuel pump, because had I paid better attention, I would have heard that the pump did not run for a few seconds after I turned on the ignition. Dead give-away.
But hey, I've got time to learn again.As to why I could not recognize the part (Oil Pressure Sender), I'll be starting a new thread on that.
Thanks again all.
