I have a 93 pro star with electronic ignition. i just won't start?
i've checked the fuel and also the spark. now the spark is very weak, is this the problem?
do i need a new amplifier?

I had the same problem with my 83 that we converted to electronic ignition. First see what voltage you have at the positive lead of your coil with the key turned on. It should be approx. 12V. If thats not present do a serch for 'Voltage Drop' here and it will give you a step by step to solve the problem. When you say the coil is ok, what is the primary resistance? For a 93 I don't think you had a ballast resistor so your coil should have approximately 1.4ohms of resistance.
In my case it turned out that we had a bad ground cable to the engine and one of the guages was shorting out. I only had about 9-10v at the coil.
