Firstly, I know there are numerous posts about this issue but mine is actually a little different than those posted before. And I already tried some of the solutions posted to those threads but nothing seems to work. Here's the issue:

When I try to start the car, I get the green key light flash(this could be immobilizer, from what I have read so far from other posts) and TPMS error (Check TPMS...).
Tried the battery test and it passed through advance autoparts. It happened this morning and by the time i came back from work and tried cranking it another 10-15 times and resetting the battery by unplugging the terminals the battery eventually discharged. Thought I figured it out and took it to Advance auto parts but after they recharged it...it passed the test. So now it comes back to immobilizer, and TPMS. Can anyone shed some light on this issue? what's up with TPMS? could be faulty relay? starter? Please help ! I really don't want to pay for towing.

 

forgot to mention the year...its 2006 TL

 

Does the car crank and not completely start?

When did this happen? Have you had it serviced recently? Have you installed any new components?

 

This happened yesterday morning. I didn't drive the car for a day. That's about it. Only thing I can think of different is I put in 89 octane gas accidently last week and the car still has about 2 gallons left in it i guess (it shows 40 miles). No services done apart from alignment about a month ago. No new components added.

 

Does the car crank at all..?

 

Yes it does...all it does is crank and doesn't start. yesterday after I recharged the battery it started and turned off with in 5-7 secs. since then it hasn't started. Also when it turned off started showing tpms msg and that green key light flashing.

 

I almost want to say a bad main relay, or at least the connection.

Try this just to humor us; disconnect the battery cables, touch both of the terminals together for about a minute (NOT THE BATTERY,CABLES ONLY). Go inside your house,and have a beer. Come back out a reconnect the cables-then try starting.

If this doesn't work. Try unplugging your fuel pump relay and plugging it back in (located in the under dash fuse box panel).

 

Thanks, I will give it a try...I will not die doing that? will I ?

 

i hope not.

But just in case:

on that note: go do it and tell us what happens.

 

heh.

 

Nothing helped...tried everything you said and eventually had to call acura roadside assistance to tow the car. Lets see what they will figure out. will keep everyone posted here. thanks for the suggestions.

 

Please do, curious to know.
