Pump going out???

[sparks57]

In case you guys haven't noticed, I have been doing an extensive look through of the archives and I have been comming up with questions from what I see.



Anyways... I came across a lot of posts about trucks not shutting off when the key turned off. Most people said it was because the pump was going.



This is scaring me because, if you remember, a few months ago for about a week I had to shut my truck off with that little lever on the fuel pump because it wouldn't shut off with the key. Sometimes if I let it sit for a while, it would die eventually.



Then one day it just up and stopped doing that. I haven't had a problem since. Also, a few weeks before it started not shutting off, I ran ATF through the system from the fuel filter because my injectors were a little clogged... I don't know if that had anything to do with it.



Should I be worried?

The not shutting off thing was my first warning that my pump was ready to die. What you should do is pull the shut off solinoid and check for metal particals. I am not saying it IS going bad, but it is worth a look.

Is removing the solenoid a complicated job? How long would it take?

 

[hdm48]

Getting at the solenoid is the biggest problem. What I did was took a metric crows foot and ground it down so it will turn and clear everything. Once you've done it once, you'll be an expert.

I think Pastor Bob has some pictures in this forum that will help you.

Thanks a lot. I did a search on solenoid removal but I couldn't find anything. Can someone post a link or something to where I can find some pictures of solenoid removal?

I just replaced my start/stop solenoid last week, and I have to do it again this week too.



It is a fairly large wrench size, and I used a " custom ground " open end of Piers' to take it out.

You will need to get a small cut off wheel and hack the top off the bracket in the way. It serves no other purpose other than make your life a misery. Just grind thru it nearly flush with the side of the pump end. Make sure not to nick the fuel line(s) near it is all.

Once you get the bracket hacked off you need an open end with the outside sides ground down to get a bite on the solenoid body.

Once it's unscrewed, use your right hand to lift it out, and your left hand index finger to be ready to catch the little metal tube with rubber end, including the tiny spring in the metal tube.

If you look at the end of the metal tube you'll see a hard rubber tip.

That is usually what tears and caused the "no shutdown" problem.

Piers told me this happens alot and the missing piece usually causes no problems with the pump.

You'll need to scavenge a solenoid off a used pump or go to Bosch and buy one.

Ok, thanks Bushwakr. I haven't had a problem since, but I will check it to see if there is damage. It will have to wait until I get back from school.

Yep, I agree with Bushwakr. The rubber stopper probably has a small chunk missing. I don't know where it goes, but haven't seen it cause any problems. Watch that spring - it is hard to find if you drop it. If you don't have access to "special tools," a metric end wrench will work with some patience. I cant remember how much a new solenoid costs. I think it was around $75.
