For the last month I have been having trouble starting the Starion. At first I could wiggle the knock box connector and it would sometimes start, and then run perfectly. It would also still start while the engine was warm (for about an hour after shutting off). Now it doesn't start at all, and the cause is no spark. I replaced the pickup coil today but still no spark. I also checked some stuff I red about the knock box connector on the forums here: With Key On: - Red Wire gets +12V - Blue/White wire gets +12V With Key Off: - No resistance between white wire and left side of pick up coil - No resistance between black wire and right side of pick up coil - Other black wire goes to ground What else can I check? Any Suggestions?

If any of you have been following my build (or several threads concerning it) you know I'm having a hell of a time getting spark. I don't really know if this is a MegaSquirt-related problem or if it involves the factory ECU so if at all possible I would appreciate it being left in VM to get some more exposure. Initially I was running the stock distributor pickup and ignitor and the car was running TBI. I first switched over to MegaSquirt with the stock dizzy/pickup and ignitor and the car had spark. For whatever reason the signal was not getting to the MS ECU so it would only start for a second or so because of the fuel injected during the prime pulse. Then, in the interest of possibly killing two birds with one stone, I swapped over to a CR125 Caravan distributor pickup and had the stock ignitor modified to control spark along with having the MS wiring, programming, and MS unit itself modified accordingly. I also had the dizzy locked and the vacuum advance removed and sealed. This was to allow ignition control through MS which would allow me to retard timing more than 7 degrees (the max allowed by the stock dizzy/ignitor setup). I was also hoping that by switching to the CR125 pickup it would eliminate the signal issues I was having. I sent Scott my dizzy, MS ECU, and wiring harness and he used a known good ignitor to modify as a core exchange. Everything checked out properly on his MS Stimulator and he even went so far as to check the V+, GND, and IGN signal wires on a car and verified it picked up an RPM signal in TunerStudio, which it did. Now, in my car, I have no ignition signal, and because of the way the CR125 module and MS work together, no spark whatsoever. I'm hoping that a couple hundred heads are better than two and we can all brainstorm to get this thing running. I used a voltmeter to check engine/body/battery ground continuity, resistance (everything is connected properly and shows no resistance) along with checking voltage at various points versus across the battery terminals (kinda a secondary test to verify the resistance results). Please help me before I push this 99% completed install off a cliff. Let me know what things I should check for. This may or may not be related, but my automatic seat belts, power door locks, and interior lights don't work. The power windows do along with the exterior lights (but the fogs don't). It's been an electrical nightmare working on this car because the previous owner hacked everything apart and I'm trying my best to fix it, just feeling a little overwhelmed right now and would like to get the car running.
