Need a fuse block cover for under the hood for my 1998 saturn sl2

hey bud let's see here there shouldn't be a single post with a 10 mm nut on it somewhere on the relay junction box on that post will be two red cables the size of a pencil one goes to either the starter or alternator not sure what color that one is but you'll see where it goes the other is short and red goes directly to the positive terminal of the battery

Passenger front seat, to the left of the floor, at the front of the center console, is a cover for fuses.

needs crank sensor replaced

Are you sure the fuse panel is not next to the front passenger's left knee, under a panel held on by velcro?

There are two fuse boxes in these cars one behind a plastic plate down by the passengers feet and one under the hood. Which fuse blew? What is your reasoning for believing you blew a fuse? Were there any issues with the car leading up to this even?

There IS a fuse under the hood...the green 30A big boy labeled power/convenience. Use a multimeter to check power coming into the relay...if it's not there probably the fuse. If it is there, could be the switches.

If it's the fuse, go to a junkyard and get one cheap. But then, they're pretty cheap new too.

under the timing chain cover on the front of the engine

Do not know what an INS fuse is but the 90s saturns I owned, 3 of them, had a fuse panel just to the left of the front passenger's left knee. pull open the panel just to the front of the console, it is held on with velcro.

the fuse panel should be under the steering wheel above a removable panel. The diagram should also be there, if not consult owners manual if available. It could also be under the hood in a black box. Just remove covers. Should be about 6x3 inches at least. Mike.

the fuse box is under the hood driver side, about 12" long and black, the fuses are under the cover. You didn't mention if you had the SL1 or the SL2.
