Engine/Transmission (1994 - 1998) fuel shut off selenoid dead @ 101,000

[carson6]

who can ship me one cheap... napa said 700 + but they must have the wrong part #

 

[Got Smoke?]

Make sure to check the relay for the solenoid first. I made the mistake of going out and buying a solenoid right away.



Got home and issue #38 of the TDR had arrived that day well in the 2nd Gen section a member with the same model truck had the same problem I was experiencing and it turned out to be the relay that you can get @ Radio Shack for $6.



If your super cheap like me just take the old one out and file the contacts down Worked like a charm for about 10K miles.

 

[JBHale]

another thing to check would be all the connections, i. e. battery connections, clean them real good then try it again. then check the relays, you should have 12v to the selenoid.

In case you haven't noticed no one is going to tell you where to get one till your sure that the old one doesn't work.

About the only time one fails is if the starter motor sticks on and the lift coil is energized for too long frying it, this is accompanied by a burning wire smell and a starter that won't shut off when you let go of the key, something that most everyone would notice.

Check what the others have said paying particular attention to the blue wire from the battery.

 

[carson6]

it's got to be it because.....

my starter was sticking about 10k ago and i replaced it with larry b's new starter and contact's . . this morning she fired up but after a shut down she would not re start just cranked so i turned on the ign. swich and assisted the lift and it went up (run position)like it was a stuck selenoid. . this could have been aggravated by the sticky starter. . the wire's and connector's look (feel tight)good and it run's when you lift it ???so where is the best place to get one. please

Call your Cummins Dist. with the eng. serial #, and cpl.



What we are trying to hint to you is that the relays mounted to the firewall above the fuel filter often go bad vs the expensive solenoid. DC will charge about $50 for the relays.



The solenoid is exp. $300 +. Yes, they sometimes go bad, we were trying to help you troubleshoot the problem rather than changing parts.



I changed the relays out recently on a truck whose owner had been to Cummins several times for this complaint, they had changed our the solenoid on his 2nd visit. He still complained of the problem intermittantly.



I freshed the starter contacts and all ck. 'd connections. After I replace the relay, I pulled the old one apart and found badly burned contacts (on the relay). I'm surprised it worked at all.



He hasn't called since, so I presume I repaired the prob.



My . 02 and good luck

carson, the blue wire from the battery I mentioned is actually a fusible link that supplies power to the lift up coil. It can melt about 6" from the battery and may be hard to see. What happens many times when someone replaces the solenoid the problem is solved only to return. The only reason it was "fixed" was because the wires were jiggled around in the process. Great dealer trick to get your money.

If you do need a solenoid Freightliner dealers have excellent prices.

Piers has them listed on his sight for about $150

Fuel shutoff solenoid kit SA-4981-12



If your sure you need one might want to give them a call.

[carson6]

thank you all ....

thank you all for the prompt reply's now I just time to fix it . no one here in big bear has relay's or selenoid's but napa said 45 for the relay. . big a said 75 . . radio shack said we don't sell auto part's but they had one just like mine for 4. 99 except it was 30n amp. (in a package marked auto relay. )@ the plug near the lift selenoid there is power to the run wire but no power to the lift wire and every thing look's clean so maybe it is the relay??!!

A relay is a relay right?

It might be a little out of your way but, in Riverside there is a place called the Electronic Warehouse. It is on Main st. Take the old relays off and they will match them. I've don it twice.

Make sure it is the solenoid. I thought mine was bad because it would start fine but it would not shut off the truck.



I removed it from the mount and found that the shaft that is attached to the bottom of solenoid was binding in the linkage. I finally got it off and used emery cloth to clean it up.



put it back on and used never-seize on the linkage. works like a charm.



sounds dumb, but check that linkage before you buy a new solenoid. From looking at it it was not rusted and showed no signs of trouble.

 

[JohnE]

Just went throught this with nopowerforme for a nostart problem



He found the problems was in the relay that supplies power to the pull-in coil.

 

[carson6]

who can ship me a relay...

part#- visa card- U P S man-am I getting closer... I will try a relay first.

 

[Joe G.]

Have you tested the solenoid yet? If not it's a simple test. There is a three wire connector near the top of the wireing mess behind the air horn. It will have a heavy white wire, a heavy black wire, and a smaller brown or violet wire. You need at least #10 wire for testing. Pull the connector apart. Connect a ground to the solenoid side of connector on the black wire terminal. Touch 12 volts to the white wire connector. The solenoid should pull up. If it does not pull up, check to make sure the linkage is not binding. If it does pull up the most likely problem is the relay. If the relay is ok, then check the relay socket to see if you have 12 volts on the terminal that is supplied by the blue wire from the battery. It may be black at the relay because of a splice of the blue wire to a black wire.

 

[nopowerforme]

AS JOHNE said he helped me with my problem along with several others THE RELAY FOR $6. 00 From RADIO SHACK IS NOT THE RELAY YOUR AFTER. I just bought mine from Dodge for $45. 00



I did everything everyone told me to do especially testing out the solenoid. Disconnect the three wired connector from the solenoid, on mine I had a ground (black) a white and a red, Ground the black, touch power to the white and the solenoid should pul in with a snap... it is powerfull, If you put power to the red , leaving the ground on,and then apply power to the white for a sec to pull in the coil. then it should stay pulled up, If not then... ..... perhaps look for a coil



But as someone suggested Piers has the solenoid for $149. 00



Good luck



JOHNE Did I tell hiim right????



Don't forget my newsletter

Any relay will work as long as it has the standard pin configuration and is rated to take the load. The Radio Shack relay will work fine.

 

[nopowerforme]

Relay from radio shack

Not the $6. 00 relay it only has 4 pins and will fit the fuel heater side and is half the size of the solenoid relay. I bought the one recomended by part number given on this site and it was not for the fuel... If Radio shack has one for the fuel solenoid can someone give me the number for it PLEASEEEEEE!!

 

[nopowerforme]

I apoligize

The small radio shack relay will work and it does fit even though it is half the size of the original relay... I don't think in fact I know I would not leave it in for very long.



It is $6. 00 and it DOES work it is a 30 amp relay.



I LEARN SOMETHING NEW EVERY DAY... ..... Again I apoligize for saying it would not

 

[Andy Redmond]

Ok, sure the radio shack relay works, but the shut off solenoid relay is much more heavy duty.



If you compare it to a relay in a Hella or other catalog you will note it is likely a 70 amp relay.



Why tempt fate and not put the right part back in at the earliest opportunity over $45. . is anyone that broke?



I'm not and I'm poor!
