2001 Deville. Can't start after reinstalling engine
Hi new to the site. I bought a 2001 101k Deville this spring with known bad head gaskets. Dropped the cradle and installed Carroll's head studs, felpro gaskets, new water pump, rebuilt alternator and starter, and new plugs and wires.
Got everything hooked back up finally and won't start. Turn key and headlights and fuel pump come on and won't shut off by key. Lights on dash come up normal and kill when trying to start to send more juice to starter. Battery charged showing 11.6v on dash computer. No clicking from starter and doesn't engage at all, doesn't turn over. Again you can hear the fuel pump turn on with the key but doesn't shut off until battery is unhooked and you can hear the regulator hissing too and lights are on. Checked fuses and the relays sound like they are working; even swapped a couple.
Currently finding stuff to do with ecu and psm. Maybe neutral saftey switch? Tried in a few different gears to see I I hooked that up wrong...
Ok swapped battery out of daily driver suburban. Still nothing/ the same thing happens. Car battery started the big 8.1 no problem and did not charge prirror. Noticed today when I shift to a different gear that the gear indicator doesn't light up at all. In park or when I move it.
Thanks again for all the help. Hope we can figure this out.
Got it! I hooked up the starter wrong. Put the tiny wire on the back of starter itself...wrong... Still didn't crank under the key but did when we removed the starter relay and jumped it.
Finally found a loose wire. Ground wire for something. Located under transmission main harness. Three eyelets total not two like I had thought. Hooked it up while key was on and pump shut off and gear indicator came on. Oh and the shifter wouldn't lock in park either before...
Started right up but sounded like a diesel and blowing a lot of white smoke. Smoke subsided but was still knocking. Looked at dash and it said "low oil pressure shut engine off" or something like that so I did. After a little more research found out the the oil pump spins from the pressure on the harmonic balancer. Tightened that up real tight and knocking went away after about ten seconds. (Will have to get an impact on it before road worthy.)
Have a few more things to finish up but pretty much there! Thanks for all the help!
