Easy Way to Bypass Theft Deterrent System

Thanks. Turns out I *think* the problem is the automatic trans. neutral starting switch!

That'd do it.

You know, if i'd thought it was an auto we were talking about thats the first thing i wouldve said as mine needs the selector wobbling a bit sometimes before itll crank!

I was wrong--not the neutral switch. Believe it or not, wife got stranded again today! I'm lucky I got dinner tonight. Car has been starting fine ~8 times, then nothing. She tried shifting in and out of Park a few times, tried neutral, nothing.

Drive ~10 miles to tow her again, tell her to try it one more time. Car fires right up. This is with the hood switch wires twisted together, which is SUPPOSED to prevent the alarm from arming.

If it isn't the alarm computer, maybe it's the starter relay that's in the pass. side "kick panel". I took a look and it doesn't appear to be easy to get that panel off. I assume the kick panel is on the side at the floor, or is it the underside of the dash?

One thing's for sure, she won't drive this thing until I (we) solve it for good.

Ahh just gets stranger. But if the car always seems to start after towing (hence movement) i'd be inclined to wonder about a loose connection, possibly at the starter signal wire (the small spade terminal) since repeated tries usually coax a dodgy relay into working, just jumps out as funny it never tries till just after towing...

Update:

The last time she got stranded she had NOT locked the car--it was just a gas up stop. So, realizing the car had never acted this way before I changed the starter, plus all the alarm stuff AND your good comment, I figure it had to be a loose connection of the small 12 volt connector for the solenoid on the starter.

Jacked it up and pulled the brown plastic connector out, cleaned the inside, closed the metal opening of the connector down a little with a small screwdriver, and reconnected it. So far so good. We shall see.

Let's hope this gets the beggar, bet these phone calls are getting rather old now! That's all else I can think it would be really, a loose connection somewhere. I suppose if this doesn't cure it it might be worth trying the connections to the trans. lockout switch too.

EDIT-: I didn't know you'd changed the starter, was it completely dead for you to change it? One more possibility is the new solenoid could be faulty though I'd doubt it, you could prove it out if it does this trick again by putting a test lamp on the signal wire that you tightened & earth. If it lights when you try to start but still no go then it's gotta be the starter, hopefully though (everything crossed this end!) cleaning & tightening this spade gets it...

Always a challenge when a gremlin gets in your car. Could be as simple as bad connection to the battery terminals, though not likely I am sure you already checked that.

I have wired a $5 AutoZone relay in parallel with it (separate switch), and that one works every time.

The stock silver relay box says "ECT" near the top.
