I have a 2004 Cavalier 2.2 eco. I had starter problems as I was removing it I broke one of the posts so I had to replace no matter what. When I did I only got a clicking noise. A few days later I checked all connections and replaced the purple wire connector to the starter at ignition post the small one. I tried to start again but no power whatsoever. I attached my trickle charger and showed 80% power & I verified the charger worked by checking my other vehicle.
I checked all the positive and negative cable points and cleaned them. Any suggestions what might be happening?

 

no power as in no dome light and no headlights, etc?

 

I hooked up jumper cables from our F350 to the Cavalier. The lights, radio, etc came one. I attempted to start but it didn't turn over. I got a new battery and I attempted to start the car but it was making a turning/swooshing sound the same sound before it starts to turn over. Also when I turned the key on but not to start I think I heard the fuel pump running/powr up. I then took off the eco 2.2 plastic plate with ths spark plugs and the relay unit. I cleaned off the electical connections and applied some Di-Electric grease. I replaced the plugs as they were a bit burnt and two of the plugs were worn down. I put everything back together and I'm back at turn the key no lights, radio, dash, or anything on. What else may it be?

 

You are using jumper cables when hooking up to the F350?

Does everything light up then?

But still no start?

 

Yes jumper cables then new battery. Everything lights up but no start. It makes a whirring sound the sound right before it starts to turn over but doesn't.
