Stalling - Ignition Module 900

posted by  someone claiming to be Hoola on  Sat May 16 15:20 CST 2015 [RELATED]

1994 940 non turbo . As I previously posted starting ~ 2 weeks ago I was stalling out. Pulled over. Waited ~ 2 minutes and was able to restart and go. Got worse & worse to the point where it stalled out every 5 to 10 minutes. Bottom line is problem was bad intermittant ignition module.

Before determining this I swapped out/replaced/bypassed : Fuel pump, fuel filter, Fuel pump relay, Fuel injector / Radio suppression relay, RPM /crank sensor, AMM, AIC . Posting this so as can perhaps help someone else.

What I learned : The OBD does not tell you if ignition module is bad( it read ok 1-1-1 all along), that ignition module failure can end up being intermittant and that sometimes recovers in 2 minutes and other times can take much longer.

What I wish : that ignition module can be tested or bypassed to test it as it is a pricey(over $100) part.

Thanks to all at Brickboard for your kind advice & help in resolving this matter.
