The power line to my starter broke off but still worked if i held it on the solenoid while someone else turned ignition. One of the times I did it and it sparked a knocked out the radio, power windows, and all items of speedometer dash except the backlight. I bought new starter and installed but no crank...read i could have blown the starter switch so i replaced that and still nothing. Already had new altenator and new battery so im running out of ideas...not to mention im really not mechanically iclined all that much and I live hour and a half from nearest mechanic. Any ideas? Maybe starter relay? That spark had to blow something. Fuses are all good though so what am i missing?
