Re: 87 burb wont start

87 is FI.
1. Put 1 teaspoon gas down it (not a quart!) and see if it will start.
Yes? Fuel system
No - ignition system
2. Timing light on #1 plug, spark while cranking? N0 - if #1 was bad, ignition system - most likely module or pickup coil or wiring. Yes - timing .

Fuel, air, spark, all at the right time.

The stumble but keep running makes me think fuel or ignition module.
