No spark, removed opti (parts rattling about-with pictures)
Gentlemen,
Long story short, the car ran fine but unfortunately, oil felt the rear main seal was a convenient way to seep out, so i pulled the transmission and changed the seal.
I also noticed water in the tell-hole in the water pump, tried opening it up to do some refurbishing but ended up messing it up, and got a new one, all fine and dandy.
However, as i today (five years later...) was attempting to start up the almost-assembled car, it would not fire. I have fuel in the tank, fuel pressure (not measured, but it was squirting out of the fuel line Schrader-valve on the back of the intake when pushed on). Won't start on starting gas either, it will not make the tiniest attemp to ignite.
Checked for spark by holding a plug to the block, but nothing.
Im thinking ICM/Coil/Opti, correct?
Since nothing has been done to neither the icm nor the coil since the car was put on stands five years ago, i thought it was the leaking water from the pump that had eventually corroded the opti.
I took the opti out and disassembled it, heard a rattle when i got it out and sure enough, one of the rotor retainer bolts was not where it was supposed to be(see pictures). The other bolt was not exactly tight, but the rotor was not wiggling about. The business end of the rotor does look like crap, is this normal wear? Is this perhaps caused by a slightly wiggly rotor touching the.....the....the metal-connector-things on the opti cap?
The question: is this the likely source of the lack of spark? I can't see why a loose bolt would cause it (since it was in the bottom part of the opti), neither the burns on the rotor, since it ran fine the last time it was on (however, still five years ago)....
Is there any way to test if the opti-electronic-thingy is working as it is supposed to with a multimeter or such?
If this isnt the cause, im glad i took it apart anyway, since it would only have been a matter of time before bolt #2 came loose too..
:Edit: Plus the fact that optisparks are fun, and pretty. I like optis.
