[alfa] 91 Spider won't startalfa-digest V10 #1

[Joe Elliott <jee@xxxxxxxxxxxxxx>]

When are you measuring these things?  How good is the battery voltage? 
I've seen Motronic cars not start due to a *slightly* low battery.  Keep in 
mind that Motronic doesn't switch the fuel pump from the AFM door like 
L-Jetronic does--it's switched by the ECU.  Your ECU diagnosis might be 
valid since you're getting neither spark nor fuel (but it could also be a 
slightly low battery, as mentioned above).  Are you detecting 0V across the 
fuel pump when you're cranking the engine?  Then and when the engine is 
running are the only two situations where you should see voltage at the 
fuel pump.

Hope that helps,
Joe
