so, i narrowed down my start issues to lack of spark.
in case you were wondering, i have a compression tester, checked it (180 cross the boards) fuel pressure was good, and both cam timing and ignition timing are right on, but non of my spark plugs were getting spark,
so i tested for spark at each wire, non got spark.
so i tested for spark right after the ignition coil, no spark there either,
busted out the fsm, and all the tests on the harness play out perfectly fine.
so i am thinking, its a bad ignition coil again,
so i buy a new one of those ( i have 3 now.. hah) and that doesnt fix it.
so i have already checked all fuses, but i think, what about the ignition relay? so i disassemble that, and sure enough, one of the wires was broke, so that got replaced.
now i thought for sure i isolated the problem and fixed it.
but now, (using a test light) i get no spark while cranking at all, i only get spark once right after i stop cranking.
which leads me to believe that the coil is getting power, but it isnt being allowed to discharge until power is stopped, when it discharges all of the power its built up.
now if i am correct in my way of thinking on how my ignition system works, would it be safe to assume the reason it isnt building up is related to the ignition condensor/resistor? the condenser/resistor is located on the wiring harness, and is detachable, and the resistor side checked out perfectly, at 2.2k ohms
i currently dont have the means to test the condenser, so i am assuming that that would be the problem, not allowing the full charge/discharge cycle to occur.
is this a sound hypothesis?
also, where could i get a condeser/resistor, because i have tried ordering an ignition condenser from courtesy nissan, and they sent me the wrong part, because it neither fits in the socket nor has four connectors.
its a ka24de in an s13 by the way.
sorry for the novel of a question, but if someone has answers, i would be more than appreciative.
