Having solved a few no-start issues on various Volvo 200/700 vehicles, I always test the following items. (they're usually the most common culprits for a 200/700/900 Volvo) Note: Some of the parts listed may not be equipped on your vehicle (I believe the Hall-Effect sensor is replaced with an inductive pickup on one of the spark plug wires).
1. Main Fuel Relay. (white, second row, far left) Resolder all connections and 90% of this time it solves the problem.
2. Hall-Effect sensor.
3. Radio Supression Relay. The Cooling Fan Relay and the Radio Supression Relay on your vehicle are identical and you can swap them to perform a quick test. Also test for voltage at injectors when they should be firing.
4. Fuel Pressure Regulator. Typical life expectancy of 60,000 to 100,000 miles.
5. Air Mass Meter (AMM).
6. Power Stage (ignition amplifer and resistor pack).
I keep a spare of each of the above items in my 780s (except the hall-effect sensor). $50 worth of parts from a scrap yard saves a lot of time and money if you should become stranded by the side of the road. I also keep a spare AMM, Main Relay, and FPR in my '87 240 Wagon.
FYI, depending on the condition of your engine bay wiring harness, you may want to keep an eye out for a spare harness from either an '88-'90 780 (6-cylinder) or an '88-'90 760 (6-cylinder). The 780s and 760s that had turbo-4 engines in them use a different harenss. Biodegradeable harnesses were used from about 1980 through 1987, and starting in '88 they had good/durable wiring.
God bless,
Fitz Fitzgerald.
