97 I30 Won't start just hear buzz and pops

[wildcat62]

I was driving my I30 home and it started to surge at a stop light. When I got it into the garage it seemed to be running ok, maybe ideling a little fast. I shut it off and attempted to start it again and nothing happened. I heard a buzz from the back of the engine on the passenger side and then some pops from the middle of the engine. That's it, it didn't even try to turn over. I just had a new starter put on it about a month ago so that's not it. Any ideas?

The only thing that turns the engine is the starter.

New or remade? New is ok, remade seldom...

Measure the +12V from the motor solenoid (supply wire from battery, under rubber 'boot') as someone starts. If u get all the time full voltage, starter is kaputt.

- Otherwise, main ground bad, maybe.
- Or the starter motor solenoid [u hear clunk if it works] does not get +12V as u turn the key:
a. gearbox inhibit switch or b. its relay stuck or c. bad ign sw.

Thanks for your help! I believe the starter is new not rebuild. The solenoid may be the pop I hear. I had my wife turn the key when I was under the hood and that's when I heard the buzz and then the pop, but it probably could also sound like a clunk. I will check the voltage. Happy New Year!

If the solenoid 'works' =makes clunk -noise, it means solenoid coil is ok. However, the other function as relay, connecting the +12V from batt to starter coils do no make contact inside the solenoid. Or the starter motor itself is faulty (brushes stick)

U have to open/replace it. They sell also only solenoids...

Quite often hitting the solenoid or the starter endplate(some tool & hammer?, wife turning the key to start pos) the contact will be realized...

---> still theres the possibility that batt cablin/grounding is oxidized and voltage drops at starter motor to 6V or less as u start. Test the voltage with 10$ multimeter.

Test.

Yes. Most important: Happy New Year!
