#8 of 236 another "no start" problem
May 25, 2006 (8:29 pm)
I have a 97 Bonneville. I tried to start it. The security light flashes, but it will not crank. I have checked the battery cables, the park-neutral security switch. I have jumped the starter and it works fine. I bought a new key, but it still will not crank. I read an earlier post that it could be a starter enable relay control switch, but I can't locate that under the dash. Any help would be greatly appreciated.

The flashing security light should go off in 3 minutes. Then you can try the key again. It means it read the wrong resistance from the chip in the key. And when you try to turn the key to start three times it locks down everything for three minutes.
It would be broken wires in the steering column, it could be dirty contact wires in the ignition lock, it could be...
You can put alcohol on the key chip area and put it into the ignition lock several times to get alcohol in there to clean the contact wires. It may help.
There is a way to cut the wires going up into the the steering column and replace the key at the top with a resistor at the bottom to make the box read the right resistance.
Was the tilt column moved up and down a lot? How many miles on the car?
The resistance system is called VATS if you want to search for info on the web.

Thanks you for the information.
The car has 117K.
I did try the alcohol with no result.
It could have been the tilt wife was the last one to drive the car... I know should not have let her get behind the wheel...
I will check out the VATS system on the internet.

I have a 1996 Bonneville that has ran perfect until a few days ago.I started the car aand it ran for a few seconds then died, and would not start(spins over fine). I then noticed that the power windows do not work as well as the door locks, interior lights and daytime headlights.The interior lights will work with the switch and so will the headlights.I don't think the fuel pump is running also.What could possibly be common to all this? I'm lost!!

Probably a bad ground. Seems to be a common problem with the Bonnies. I have a 95 and found the 3 grounds under the hood had a lot of oxidation. Two more grounds in the trunk by the top of the wheel wells and two in pass compartment one on drivers side and one in passengers front side just next to the door under the dash. Hope that helps!

Thanks for the info, however could not find any ground bad or loose. The positive cable end was coroded but cleaned it and no better. When I hooked up the cable the interior lights worked till the key was turned on, then nothing, It was like the ECM was reseting but still won't start or windows and door locks don't work. Have never ran across this one.

Saw this post. Son's car had same thing. Shut it off & would crank, but no start. Wierd stuff with the indicator lights as well. Turned out to be the "inside" positive battery cable. When you tighten the cable, it makes good contact with the starter cable, but the red insulation material prevents good contact on the inside cable. If you have room, put a regular or lock washer between cables. You might need a longer bolt to try this. If it now starts, best bet is to get new terminal ends. You can leave the lock washer on, but it loosened up on our car after 6 months or so.. Good luck
#16 of 236 96 Bonneville!!! terrible problems

I have looked at all the grounds I can find, none bad. I would like to know if the BCM could have blew, because the positive battery cable was bad corroded? Vehicle turns over fine but will not start and power windows,door locks interior lights and daytime headlights don't work. Any help will be savored forever. Thanks

Do you have spark at the spark plugs while cranking?
Do you have fuel injectors working during cranking?
Do you have fuel pressure?
Next door neighbor just had a 97 Monte Carlo with 40K that lost its fuel pump. It had sat a lot in the garage and was driven on low fuel levels most of the time since he inherited it from his dad.
