I have a 1997 12 valve with 270K on it. Was having problems with sometimes when i tryied starting it it would act like it started running then die right away , i mean like 2 seconds. So i posted up on here and another site and came to the conclusion that it is the Shutdown solinoid going out. My question is, tst makes a shutdown solinoid kit, its like 170 bucks, looks like the whole piece i need, just wondering if anyone ele had this problem and where they got the replacement part.


here is the link ot the tst product:

You might want to test the relay for the solenoid. There is a large relay up on the firewall just above the fuel filter that controls the 2 circuits in the solenoid. 1 is the "pull" circuit which is powered from the starter contacts and applys over 30 amps to pull the solenoid open. Then the "hold" circuit that is low amperage that holds the solenoid up.

Did the "other" site mention the blue wire from the battery? That sometime corrodes and supplies power to the solenoid circuit.

As far as solenoids go, thats not a bad price. PDR also carry them.

Does your truck start when you pull the solenoid up into the run position? If so look into the thin blue wire from the driver's side battery as posted above. Also burned starter contacts can cause this condition as well. You can replace the contacts with heavy duty ones from here http://www.fostertruck.com/dodge/default.htm
for a lot less than a new solenoid, and they rarely go bad.

Take it off, take it apart, clean the bore and the plunger and reinstall. I'll bet the boot is shot too. You can get a new one from Larry Bs

or do like I have for the last 300k miles and not use one at all.

You can also make a boot out of a piece of bicycle inner tube and zip tie both ends. Having a boot thats not torn will go a long way by keeping corrosion out of the solenoid.

I guess everybody already covered everything. I will add, when reinstalling it, turn the key on. That will hold it together, and it's much easier to put back together.

The last thing you want to do is replace the solenoid. They rarely fail and when they do are visibly burned up on the outside. There is no such thing as a weak solenoid, they either work or they don't.
The problem almost always lies elsewhere.

I agree with Bill here. I had a solenoid go bad and there was absolutely no mistaking it. Lots of smoke coming from the side of the IP and sparks shooting out of the top of the solenoid. I would think to check either the starter contacts or the relay.

thanks for all the help guys. going to see if the blue wire or anything is corroded to start with. Kodi
