I have a 2000 deville, whilst replacing spark plugs & doing some injector & vacuum repairs. It wouldnt start all of a sudden, I thought it was the starter, as I pulled it out, I accidentally engaged the starter & it attempted to turn over. (forgot to disconnect power 馃槖) but also discovered that the cable was missing its nut or clamp or whatever. I questioned if it was that was the problem then, cos I'd been knocking that cable around, so a bad connection made sense. Put everything back together & notice the ground wire to the starter (I assume), its the one right behind the radiator, pain to get to... anyway, tried to start the car & got clicks now, & consistent. Would this ground wire be the issue? -- as a gounding cable is much cheaper to replace than the starter.

I have a p1634 code on 2000 caddy DeVille -- she cranks but don't start, fuel pump tested fine, but the injectors don't pulse. After some research, concluded that it's either the icm/coils - the crankshaft sensor - or the pcm is done, but I'm not sure where to start without breaking the bank. Any thoughts? Plz help.

Don't overlook the injector fuses. I believe they are labeled IGN1 & IGN2.
