Oldsmobile alero won't start after being rear ended Sign In

1999 Alero 134k 6 cylinder. I just picked this car up today and it cranks but wont start. It sounds a little funny, it goes crank crank crank pause, crank crank crank pause repeat. Also, all of the electronics are going crazy. When I turn on the high beams the doors lock, the Guages jump around and the dash lights flash randomly. the previous owner said that after being lightly rear ended the car stopped running. He replaced the fuel pump and plugs and wires. Any ideas would be great! Thanks

Can you record the noise of the engine cranking and post it in here?

What is the voltage at the battery terminals while the engine is cranking?





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I may be able too tomorrow. It actually sounds perfectly normal when it cranks, but the pattern is weird to me. It cranks 3 times and then has a momentary pause and then repeats

Well I brought a new battery over today (the car sat for 6yrs and the batt tested bad) and after installing it it will not crank at all. Not even a click from the starter. The fuel pump relay would click (I tried swapping it with the horn relay) and the electronics are still going haywire (the trunk opened when I pressed the emergency lights button. I'm wondering if this could be a computer issue? Or ignition. Issue (it takes some wiggling before the key will turn) or maybe a security device issue?

What? Car sat for six years and you are surprised at anything? It cranked at all from the first battery is almost impossible.


Total project if you want this thing to be useable at all IMO,

It only cranked because I had it on a 40amp jump start charger. Yes it is a project but it was free so I'm up for it. So any ideas where to start?

OK - Just need to know you know what you are in for. 6 years depending on how it sat and where will be a whole list of things to deal with from a known bad battery if new 6 years ago can't be good now and you should know things like that. Gas isn't stable that long so another issue.


Oil had to have settled to pan making engine so dry it can "gun rust" or worse badly, lifters collapse, compression lost and forcing it to start risks total engine destruction as it could by dry as a bone, oil may not circulate fast enough to save itself.


That choice to start from a charger worries me mostly as my own states a 100AMP choice to start a dead car. When the fire and smoke finally clears I'll let you know more about that trick! NO - the battery needs to be good and charged first then work with it. All methods of powering the vehicle with a known dead (I mean dead not just discharged) battery will just suck into the dead hole that battery is not help start the vehicle rather mess up the show.
WOW - Gotta know what features it may have as well. Any OE or aftermarket items for theft controls have to be considered and set such that it would run if there was nothing wrong.


Hit from the back IDK what might disable the engine as well. I'm NOT sure but something has to disable it if hit hard enough such that fuel doesn't pour out of a wreck under power at the time of the wreck.


I would be trying to wet the cylinders with oil any which way possible before cranking this much more at all then find out what's next to make it run then run well. It's going to take knocking off problems one at a time till it can run then when it can the list will probably go on to all the seals and things that will leak all around the thing as a whole from water pump, steering items, shafts all over and brake parts for starters.
It's a project for sure just from the time it sat never mind that it was rear ended and what to do about that if not already dealt with?


My head is spinning. Were tires on the ground or what? Those can't just sit in one spot that long and the list goes on. Just know what you are getting in to,
