Default Intermiittent starter problem

My 89 automatic has developed an intermittent starter probblem - it's only done it 3 times so far but....

When I turn on the ignition all the instrument panel lights show up as normal, with 11.9V battery voltage displayed and I hear the fuel pump. When I turn the key to start there is no effect, nothing dims, battery still shows 11.9V and the motor doesn't crank, there's no click from the starter or anywhere else that I can hear. The first time it started after I left it for a few minutes - motor was cold, the second time I jiggled the battery cable under the hood and it started - motor was cold, the third time jiggling had no effect but it started after a few minutes motor was warm. The first time was a few months ago, the last two times were over the past several days. The starter is about two years old.

Could anyone suggest where I should start troubleshooting?

Thanks,
Tony

Sounds like you answered your own question. Clean and secure the battery cables after you do the same to the starter wires, also check the ground cable.. It's the cables for sure because even if the starter was going bad you'd get a click or a dimming of the power but in your case the power isn't reaching the starter.

Hi I have an 85 which had a similar problem. Mine occured when I had been driving, stopped to buy something or just stopped for 5 15 minutes and when trying to start I had exactly the sae symptoms. It could also happen if I was so unfortunate to stall the engine and it did not start or more correct crank.
By coincidence I discovered that if I turned the ground batterycable contact loose and retightened it it was ok.
This is ofcourse not feasable and I measured the voltage losses and everything were normal. All ground connections from the battery to frame and engine block was good within specs.
What I did was to change to a new starter and everything became good.
I have to say I cleaned every contact on the battery groundings and also on the starter.
I do not know what was wrong I have not invested in time to look after faults in the starter., but now after 3 years everything has not created any more problems.

Sometimes a starter will "act up" if it gets hot. On other cars I've owned, I covered the starter with a heat blanket.

Check connections. Starter solenoid can sometimes cause the problem.

On 86 and up if the pellet in the key is worn a bit it can cause a no start condition. Try using your spare key and see if that helps.

DAM!! I always forget about that VAT's crap In some situations that could very well be the case. Shine up the resistor with a peice of emery.

Default Ingintion Switch?

I have a 87 and had the same problem with no start. The key pellet failure getting the correct resistance value to the VATS board will take five minutes for the VATS to reset. If the VATS system is functional and the battery cables and grounds are good, I would suggest replacing the ignition switch. The voltage for the starter solenoid is provided via the ingition switch. I replaced the switch and have had no problems energizing the starter since. I found the internal contact for the start circuit had worn to the point that the spring loaded contact had cocked in the plastic bore missing the other contact.

Thanks guys, that's given me some ideas to try. I did clean the battery cables when it did this a few months ago, maybe I didn't clean them well enough...sigh. I'll try using the spare key - and that 5 minute delay explains why it worked after a few minutes. I'll keep you posted when I figure it out. Thanks again.

The 5 minute delay caused by the VATS reset time gave me the clue, on every occasion I had to wait a few minutes before it would start. On inspecting my key (the original one I've used since I bought it new in 89) I saw that the little metal bar that goes through the black pellet was flush with the pellet. Looking at the spare key I saw that the bar stuck out about 1/16th inch on each side of the pellet. I've been using the spare key for over a month now and no problems at all. So, it looks like my original key was worn out and causing an intermittent bad cannection with the VATS system. Thanks all for your help, I would never have thought of a problem with the key.
