    help my s15 wont start, no spark.

    hi guys have t been around in a while, few other things have taken over from the car the past year, anyway

    I Have a s15 spec-r, It was parked up for a year, last week i charged the battery and it started with the the first turn . It Started 2 more times within 5 minuites and now it wont,
    its getting fuel. i pulled a sparkplug, earthed it off the block to test it, it wouldnt spark the first few times i tryed, and then suddendly it sparked and the car started. i put the sparkplug back in and it wouldnt start again, i pulled the plugs again to test but now they wont spark at all. I ran a diagnostic and it returned a 55 code (no fault codes present) i found this strange so i unpluged the CAS Turned the car over and ran diagnostic again and still it flashed a code of 55.... surly with the CAS unpluged the ecu would return a fault code for it?? I checked every fuse and relay to see if any where blown and they are all ok, Help i want to get it on the road for the summer

    Basically what would stop the fuses sparking on startup as when its running its running fine.

    When i checked the coilpack earth at the back of the engine it looked a bit damaged, so as i tryed to fiddle with it and take it off the wire snapped off in my hand at the bolt, it has 4 small strands of wires and looking at the breakage it looks like 2 strands where broken already, i rejoined the wire to a cable and joined it to the earh on the manifold, so im happy it has a good earh, as for the wireing on the rest of the loom ill have to strip the wireing and see but it looks ok tbh.

    Should i be worried that the ecu is registering no faults? Even when the cam angle sensor is disconnected?

    No idea what you should get from reading at the coils there. Probably not this, but has it got an immobiliser?

    1 year later still not sorted?
    With key on the 3 wires will be in no order:
    12v
    Signal (oV I think)
    Earth (do continuity test)
