'91 legacy no start, no spark.

[willworkforbeer]

Per the Chiltons book tested and/or replaced both the coil pack & ignitor module, no help. Checked the computer, it has a code #24 (air control valve). Which air control valve is it? At the coil pack I have 12v with key on at input wires #1,2&3, 4v with key off. The other tests chilton recommended were spark plug out resistance (ohms 1 to 2 test & 3 to 4 test, both were 0 ohms (O.L.) on the meter. The other test was input wire #1 to #2 wire (1 ohm) & #2 wire to #3 wire (1 ohm). My prior experience with mass air flow sensors have always been it will start but then immediately shutdown. I'm lost & I need your help!!! I posted this yesterday on the USMB site and got no help so I did a search & found this site I hope you guys can help. Thanks. Further research shows code #24 as the idle air control valve, my understanding is that the IACV would cause a lousy idle but not a no spark condition. Does anyone know which components would cause a no spark condition?

did you just put in a new motor? or did you buy the car this way? did you mess with the timing in any way?

So the motor turns, it just doesn't spark, correct? A faulty IASC shouldn't cause a no-start. You can always try pointing a plug conntected to a wire to a ground and have someone turn the key to see if it archs (old fashion way). Perhaps it's not a no spark condition, but rather a no fuel issue (unless you verified that already).
