Installed new shutoff solenoid, now have power problems...

Postby Jfriedlin » Sat Jan 02, 2010 7:33 pm

Lets see if you guys can figure this one out. Here's the whole story, About a month ago my fuel shutoff solenoid on my 89 W-250 burned up driving down the road and shut the truck down. I gutted it, rigged up a manual shutoff cable, no big deal. Finally ordered a new shutoff solenoid, got it yesterday and installed it, no big deal. I started the truck up, it fired and shutoff. Tried again, same results so I gave it some throttle, it fired right up, stayed running. Let off the throttle, engine rpm slowed down as I let up on the throttle, when I came all the way off it it shut down. Somehow, my idle got changed, so I adjusted the idle everything seems good, but when driven on the highway, Im lacking some power and about 8 lbs of boost less than before I changed the solenoid. I've looked everywhere for a good answer to this, just for kicks I pulled the solenoid out again and looked at everything, reinstalled, same results. I guess next Im going to try putting the old gutted one back in and see what happens but its acting like the throttle index is off, but it or nothing else other than what is necessary to get to the fuel shutoff solenoid is touched. Any ideas?

BTW the truck runs smooth no smoke, not even black smoke anymore. It ran fine with the old solenoid and with the old one gutted was about the same. Now with the new one Im lacking power. I still have the old solenoid and the spring and plunger out of it, just the electrical part burnt up. Thanks for the help

So todays experiments included taking the new shutoff solenoid back out, comparing the length of the plungers, they were the same, testing the solenoid and it sucked the plunger all the way in, taking the spring and plunger out and reinstalling, no change, and bleeding the injector lines incase some air got in, no change whatsoever.

There was no old plunger in there for about a month or two. It was an instant change right when I put the new solenoid in. IDK maybe a pice of trash fell down in there but that seems like i would have a miss or something

Tried reindexing the throttle shaft yesterday but no luck. I got the idle up but too far and couldnt get rid of it with the dle screw so I had to put it back
