Re: 1993 Pontiac Bonneville " Won't Start" ?? HELP?? [neggie] by imidazol97

Is the "security" light flashing? If so, that means the key resistor is not getting read correctly and the VATS systemis locking out the starter. After 3 minutes you can try again with a different key if you have one or with a key where you've cleaned the resistor. The wires n the steering column break after tilting the wheel up and down millions of times. Or the contacts inside the key cylinder don't contact the key like they used to do.
 
Or if your security light isn't indicating a wrong key chip reading, there are problems with batteries they age. Some of the folk here need to use a jumper to a good battery and see if they can start their car. There also can be corrosion on the battery cables at both ends and on both cables. There have bee problems with battery acid leaking around the contacts and the acid wicking down into the cable inside the plastic and deteriorating the cable.
 
A starter can go back and just make no noise when you turn the key to crank. The check there is to use a voltmeter and see if you're getting current on the starter connection at the starter under the car when someone turns the key. A friend of mine actually used a jumper cable to go from a battery charger that has a surge capability to give jump starts and contacted the starter terminal to check his starter--nothing.
 
If you've been getting oil dripping under the car from the oil pan seeping slightly over the years, that can get inside the starter and cause problems.

have a 1995 Pontiac Grand Am GT with a 2.4 liter quad 4 engine. It is also a 5 speed with 154,000 miles.My car ran fine until i put a for sale sign on it in my front yard(go figure:). The other day i went to crank it to wash it off from sitting under the trees and there was nothing but a click. Well after about 6 clicks it started turning over BUT would not crank. I turned the key off and try again and there is a click again. Sometimes it might take 2 turns of the key and sometimes 6 or 7 times before the motor starts turning over. Not sure what the deal is so out of curiosity I had my wife come out and try get it turning over(after a couple of trys) and I sprayed starting fluid into the breather. It acted like it was going to crank then but to no avail. Could you offer any advice on this problem and thank you

If you're saying that it's not turning the motor over and you're just getting a click, I'd start by removing and cleaning and inspecting the battery cables at the battery. See if there's corrosion on them. If the positive has more than one cable layered onto a single post check between them carefully for corrosion from the battery acid atmosphere.

I am having the same problem with my Boneville cutting off at highway speeds. Did you discover what was causing your problem?

Can someone PLEASE help me with this thing?.... by tulnio

Hello,
 
1996 Bonneville...
 
It all started out with an occasional missing. We then progressed, (or digressed) to an all out cylinder 3 misfire code in the car. Replaced the plugs, same issue. Talked to a buddy at Auto Zone and tested the ignition control module. It was bad, replaced it. Still won't start. Checked the spark on the plug wires at the plugs, all 6 are good. Got another buddy to clear the codes, and still don't have any codes, but the car won't start. Sometimes you can hear it try to fire off two or three times, then is just turns over. The wonderful scent of fuel is present but not too strong.
 
It has been suggested that I try a crankshaft position sensor, (any insight on this?)
Can this thing be tested without an O-scope?
 
Is there anything else I should take a look at?
 
I would REALLY appreciate any help with this thing.
 
Thanks,
