Is there a roller or switch to adjust the dash light brightness? Have you just accidentally bumped it when doing the stereo install and switched it off? If not then it's likely that you have blown a fuse while wiring up the stereo. The easiest way to check fuses is to buy a cheap test light from any auto parts store and hook the clip lead to an exposed metal part of the body (door hinges are usually good) and probe each fuse at both of its exposed terminals (without removing the fuses). The test light should light up on both of the terminals, if it lights up on only one then the fuse is blown. If it doesn't light up at all then the circuit does not have power to it. This test should be done with the key in the on position. Also, the fuse box cover may have pictures of the relevant circuits on it, and you may be able to figure out from the picture which is the fuse for the dash lights and just pull it and visually check it.

Has it had an aftermarket Stereo Fitted? This is the first place I ould look if it has..

For the 100 main amp fuse to blow it has to be a alternator issue , ECM or dead short with the electrical part of the ignition switch.
If the alternator is replaced and still the fuse blows then check the actual electrical contacts of the ignition switch to see if they are shorted out.------
Check the wire between alternator B+ (large wire) and battery for problems.
check negative ground wires to chasis and motor.
---------
Also recheck all battery, starter alternator and ground wires and see , that no wire is connected in reverse order.------
Also try cleaning the 100 amp fuse socket with contact cleaner and then install the fuse and see , if it still blows.------Many a time fuse socket itself gets dirty and cause fuses to blow.------
Getting this possibilities checked should help.Thanks.Helpmech.
For the sake of completeness, here's the full no-start Troubleshooting Guide for the 2001 6 cylinder 3.5L MFI Mitsu Diamante, but the problem with your car is line item #6 - the ECC (Engine Control Computer) is shorted/dead. Without an ECC, the Diamante will (a) get no spark, since the ignition timing comes from the computer, and (b) get no fuel, since the fuel injectors are operated by the computer as well. The engine will turn over, since running the starter motor is a non-computer controlled matter of a correctly functioning ignition switch, a charged battery, and good wiring to a functional starter motor/solenoid, but will never start.
The clue pointing directly to the ECC failure is the blowing ECC fuses. These fuses are blowing to tell you that the ECC is shorted dead.
Since the ECC is expensive, exhaustively check out all other possible sources of the problems, but with so few problems causing loww of both spark and fuel, combined with the blown ECC fuses pointing directly to the ECC, it seems that the ECC is the only culprit.
Here's a used 2001 Mitsu Diamante ECC at Ebay for $175.

The fuel pump strainer is a sock-like strainer in the fuel tank on the input side of the fuel pump designed to protect the fuel pump by straining out any debris in the tank (similar to the way that the fuel filter protects the engine/fuel injectors/fuel pressure regulator).
