hi guys a few weeks ago I bought a 1989 f250 with a 5.8. ive had replaced the starter and solenoid once, but had to buy another solenoid because I wired it backwards, cause it sparked off the battery terminal when I tried to put the battery cables on, so once I got the new solenoid on and made sure it was wired up right, I went to fire up the truck and I hardly turn the key and it starts cranking over and now the starter wont disengage im think my ignition went bad but I could be wrong thanks.
