1999 Mercury Sable wagon - 168,000 miles
Sometimes after running the car around town, I return to the car, only to n
ot be able to start it. I turn the key, all dash lights are on - no crank,
no start, nothing. I hear the fuel pump charge, but that's it.
Battery is good. Switched relays in the Power Junction Box - no difference.
Replaced the neutral safety switch (transmission range sensor, etc.), but
now I'm wondering if that NSS was bad? Tried starting in other gears (it ac
tually has the same symptoms as trying to start in other gears). Starting i
n neutral is the same problem. Turn the key, and nothing. The NSS is tight,
and like I said, will start fine, cold.
Checked the red wire from the battery (thru the Power Junction box) to the
solenoid's primary power post - no juice when the car is acting up.
Seems if I let the car sit for 10 or 15 mins, it will start. I've heard peo
ple talk of an immobilizer, and the vehicle theft system, but I don't know
the symptoms of those devices. Would they cause the engine *not*
Often, to force a start, I will pull back on the spring-loaded gear shift l
ever (column shift), and release it while the key is turned to START positi
on. I may have to do it 10 or even 20 times, but eventually it starts. I fo
und this out by trial and error.
Again - to summarize:
Starter (didn't go into detail, but checked the solenoid, and starter)
Replaced Neutral Safety Switch
Swapped relays in the Power Junction box (broken wire? how to check)
Oh, and replaced the Ignition Switch Block
I would like to bypass the NSS to see if that makes any difference. Anyone
know what pin(holes) to jump to do that? Or how to find it out?
Thanks for taking a look!
