I have a strange problem with my Mercury Sable 2003 LS V6 3L. It has about 85k on it, I brought it about a year ago and the previous owner has taken good care of it and so have I.
The issue is the car is not starting. It won't crank.
A brief history, this happened 2 weeks ago also.
One fine day, I took the car out to the grocery store, came back, everything was fine. 20 minutes later I had to go out for something else and the car wouldn't start, no crank.
The first time, I put in the key and try to start the car I hear one click, then next few times, i try to start there is no noise, no crank, nothing.
All the other electronics are working fine. The lights, radio, ac everything seem to turn on properly.
So, I figure the car has to be towed to the shop and called a tow truck guy. The guy showed up in couple of hours, tried starting the car, didn't work, he looked under the hood for loose contacts, anything obvious, the fuses, no issues found.
Then he tried locking/ unlocking the car with the keyless entry thing multiple times and again tried starting the car and voila, it started.
I asked him what the problem could be and he said he couldn't tell, and the car started somehow, as he didn't do anything, other than the usual checks.
Immediately, I went to autozone, got the battery checked and was told it was weak, probably few years old, so I replaced it with a new one. Started immediately, went home tried starting it few time worked fine.
Then the car started, everything worked fine no issues, for 3 days.
After that, I was out of town for a week and the car has been garaged. Today morning, it started immediately, drove me to work.
In the evening after work, it started fine, I drove to nearby store (about 5 miles), came out of the store in 15 mins, tried starting it and it won't start.
The same symptom as I had 2 weeks ago. no crank. All other electronics turned on. I looked under the hood, things looked fine. I tried locking and unlocking the car multiple times. No luck. No start, no crank
I took a bus ride home, it is left at the mall parking lot, all the mechanic shops are closed.
First thing tomorrow morning, I am taking the bus to the mall. To look into it further and take it to the shop or something. It needs to be fixed, my only transport.
My question is, What are the the potential things I can look at.
From my initial (blogs and forum search, inexperienced) analysis,
It could be grounding issue or
something with the security, alarm system. or
my key has lost its programming and needs to be reprogrammed.
I have seen in some places where similar issue like mine were caused by improper grounding. If that is the case what are all the places I need to look at.
Any other ideas, fixes?? any help would be great.
Thanks in advance. :)
