STARTS WON'T RUN

1986 Volvo 240

Electrical problem
1986 Volvo 240 4 cyl Two Wheel Drive Manual 300000 miles

Getting gas and spark, starts, but no power and dies. Checked everything my mechanic friend and I can think of. Ever see or hear of anything similar?

Check the exhaust system could be a clogged catalytic converter if okay check the fuel pressure with a gauge and comeback with the readings we start here.

Exhaust is clear and I repaired main fuel pump (hasn't worked since I bought the car lol so have two pumps now, no difference in problem) my friend thinks it could be the mass air flow sensor (filament intact and clean) and wants to know if there is a way to test.

Inspect and test all the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note: If it doesn't apply disregard.
