A pretty simple way to check if your computer is dead is as follows:
Turn your ignition on but do not start the car.
Under your ashtray you will find a plug with six(I think) slots.
With a paperclip or screwdriver, jump the two adjacent slots that look like they could be connected (no divider).
You should hear clicking noises coming from the carb. (the solenoid cycling).
If you do, the system is still working. If you don't, it isn't proof that it's fried, but it is an indicator.
