Hi!
Sorry for my bad English...

My car is a '93 Mazda MX-3 SOHC. I made it Turbo and since that I'm having problems with the main relay. Everytime I put a new Main Relay, it burns it or damage it. So, what I did was to put a cable to make a "jumper" and that way the car starts. After taht, my car was working greeat for about 3 months. But, the problem that I'm having now is that the engine doesn't start. After a while trying to start the engine it seems that it will start but it doesn't start. I try again and it does the same thing. I have to hit the gas to try start the engine and when I hit the gas it tries to start. When the engine finally starts, it has a failure. It seems as if it was working without a cylinder. It makes the same noise as if it was working without connecting a spark plug wire. After a few minutes it stabilizes and works fine. The peculiar thing is that some times the engine starts but some times it doesn't starts. I have verified relays and fuses but I have not found anything.

I will appreciate if somebody can help me!!

Sounds like whatever was causing the main fuse to blow might have gotten worse.

Check your fuel pressure regulator and fuel pump, also start tracing wiring as you got something hooked up wrong if you are burning out relays, chances are you got a short to ground somewhere, and pray that it has not burnt up the harness.
