The other morning my 1989 Mirage failed to start. There was no warning the
night before. It has no injection pulses, but has power to the injectors, coil,
and distributer and the fuel pump runs. If I run a vacuum line to a gas can it
will fire until I stop cranking, than die. The signal levels from distributor
for the TDC signal and crank position were different, so I tried a rebuilt
distributer, no luck. I feel like it may be the computer, but that is an
expensive conclusion to jump to. Can anyone offer some insight?

check for pcm codes, those computers are common falure, probably doesn't
have spark either

Thanks for your reply. The problem was the computer. Because it seems to have
failed at the instant of shutdown or startup, I am wondering if the computer may
vulnerable to voltage spikes. I guess I'll have to do some checking. I don't
want to replace this thing every 5 years. :-)
