Heres the story from back to front:
I have been driving a 1998 Suburban, 5.7L, 144xxx miles, as a backup vehicle while I finish working on my truck (which is getting the turbo treatment
). Last Saturday I went out for a while, came home without experiencing any problems with starting or running, and parked it for about an hour. Tried to start it later that night to go get something to munch and POW, the truck wont turn over. I assume its the starter sinces its been cranking slowly (but not super slow, just slower than usual) every now and then. Get a new starter, put it on, cant get it to crank still, assume Im shimming it incorrectly, go get my old starter benchtested by a local expert and discover my old starter works fine. Reinstall the old starter, still wont crank, take the battery to Autozone, discover the old battery isnt any good, replace it with a brand new battery, still wont start. Take off the alternator, take it for a test at Autozone, find out the alternator is good. All the battery cables look good and I cant see any binding or breaks in the wiring. So after all that Ive still got a Suburban that wont crank. ...Any ideas? Please? Ive tried to run a wire from a starter bolt to the negative battery terminal to see if maybe a ground came loose, but that didnt help either. Thanks in advance.
