02 Astro won't start, just has clicking sound Sign In

Hi Guys and Girls,
My 02 Chevy Astro has not been able to start, some tips would be great. The first time i tried all the displays in the cab weren't working but the engine started fine. Ran it for a while then turned off to see why the displays were blank. Second attempt all i got was a clicking sound (starter solenoid i guess), all electrics in the cab still work however. Ive tested and charged the battery at the mechanic but still just getting a clicking sound and no turn over. All terminals look fine and clean and bolts are tight in the battery. Any ideas on the issue would be much appreciated?

Thanks!

Is this "clicking" sound like rapid fire or a single click/clunk then nothing? Matters. Good looking connections mean little they are suspect now no matter what. Battery cable must be good all along at battery and pos to starter neg to engine block.


Battery testing can be plain inaccurate. So fine it might show proper voltage but does it have the amps needed counts?


Turn on something the stays on when asking it to crank like headlights and see if they go real dim or even a dome light if no other testing equipment.


For GM side posts jumping isn't very useful to a known good running vehicle or jumper box as the bolt only goes to the battery at the battery not on to the cables if the problem is cable ends there are eyelets inside that love to rot out unseen many times if covered.


Some you might just tug on one (go easy) and it would snap to if battery is really good. Right now I suspect those cable ends right at the battery as a guess.


If dash light do nothing at same time nothing but a single click when trying to start you've probably lost all battery power to vehicle for that time (seconds only would count) radio presets and clock would likely be lost as well strongly pointing towards battery cable anything for now,

Thanks Tom,

The clicking is rapid fire and amps were good when tested at the mechanic. Ive tried jumpstarting with the same result, just clicking.

Ill check cables and headlights and get back to you.

Cheers!

In a hurry sorry. You don't have enough delivered amps. If you can safely jump to the battery cable end at starter and to engine block you can at least get it going to where you need to clean up that problem.


IMO, most AMP (real power ability tests) for a battery are flawed. It just might be too weak but show good voltage. It needs to be load tested alone then connect to car/vehicle or you are not going to crank this engine so easily.


Again, the problem is somewhat common for GM side posts out of your sight,
