Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
During no start do you even hear a click or nothing at all? Thanks.
Does starter seem to be making the clicking noise? Thanks.
Monitor power on large wire going to starter and small wire when trying to start, both should maintain at least 11v. Let me know, thanks.
Use a multimeter to check voltage on both wires going to starter with key in start position. Let me know, thanks.
It shows 12.2 voltages on both wires while trying to start? That doesn't make sense.
Does the small wire get any voltage while trying to start?
That is correct.
Sounds good, keep me updated. Thanks.
So with key in start position both large wire and small wire have at least 11.4v?
I'm guessing vehicle is starting right now? If both wires have power that means engine should at least turn over.
Make sure case of starter has good ground. If case has good ground and you are sure both wires have good power then I'd recommend replacing starter again. I'd also manually turn engine over with breaker bar so you know it is not seized. Let me know how it turns out or if you have more questions, thanks.
