1984 Oldsmobile Delta 88 V8 Two Wheel Drive Automatic

I just completed a tune up on my aunts car, I started it up after the tune up was complete, shut it off, and now it won't start. I am getting fuel and have good spark. It turns over but won't fire. I am completely stumped, please help I you can.

Were you having trouble before the tune-up? Any codes?

the datalink connector should be under the left side of dash, to access codes. Not sure which connector you have, either 5 pin connector or 12 pin connector, not both. If the 12 pin, turn key on, no crank, place jumper wire between terminals A & B, then the check engine lite starts flashing, you count the flashes to get the codes.

No problems before tune up, check engine light is on. I will check codes. How will I know what the codes translate to?

You can post the codes here, myself or somebody else will tell you what they mean. The first code will probably be code 12, one flash, slight pause, two quick flashes, may repeat three times before moving to next code. Two digit codes.

I checked the codes and one said it was the ignition control module, took it off and got it tested. Was not putting out enough spark. Codes were 12, 24, & 42. Will replace ignition module tomorrow.
