1991 Buick Century LOSS OF FUEL DELIVERY - DIES IN FLIGHT

Fine, just needed to be sure I was fully inderstanding the method. I've obtained the niod lite and will check this tonite.

To summarize, if car is in failure mode, and the tickle produces a blinking noid lite, then we have eliminated the ignition module under the coils, correct?

If this happens, do I then buy the computer, or do another test?

If no noid lite response with the tickle, do I then buy the ignition module?

Thanks.
