  Thanks everyone for all the help and guidance up to this point.  I'm still having problems from this car, here is where I'm at - Still don't have spark, and wont start, still really don't know if I'm getting fuel, because I figure I need to find the spark problem first or there is no hope.  Service manual says to check power output stage - I followed the tests to the letter, even testing the individual wires - basically, if you get to the bottom of the list and you still don't get signal to the power output stage, then it says your ECU is bad.  Ok, fine, replaced ECU - still no dice.  Then I say, well maybe the manual doesn't state all the things that could cause the signal to not be there. (I know, longshot, but bear with me)  I checked the Cam sensor, OK; Crank sensor, OK, anything I'm missing?  So, now what do I do?  Did I just happen to get an ECU that has the same exact problem?  What am I missing?  Back to the original issue - how does running
 the car dry of oil cause a no spark condition?  Anybody got any ideas?  Thanks.
