I 've recently had the injection pump replaced(85,000 miles) and about 8k later the lift pump was replaced. Less than 300 miles later the truck has started to stumble again. I've read in earlier posts that the Edge EZ boxes are sometimes not grounded properly. Does anyone know how to make sure that isn't the problem. Any other input would be greatly appreciated.

temporarily disconnect the EZ and see what happens....1 thing you said is why im posting, They replaced your inj. pump and only 8k miles later they replaced your lift pump...was your lift pump original before that? i just hope you didn't damage another inj. pump because of low lift pump pressures....do you have any codes coming up? that could of been the reason your original inj. pump died....

The lift pump was original. I asked them(dealer) about the lift pump at the time they replaced the inj pump. Of course they said they don't replace anything that's not going out. Don't know about the codes cuz I don't know how to get them to show without taking it to the shop and having it plugged in.

you can try the procedure in the thread marked "did you know (99 owners)" right here in the 24 valve section a couple of threads down, that might work...i would definitely try disconnecting the EZ ( i know it's hard to do! ) and see what happens first...do a visual look at the ground to make sure it's making good contact and also, check the connection to the MAP sensor for cleanliness and a tight connection...this is what i would do anyway....good luck...

I did the procedure you mentioned and after it did it's thing the odo went back to the miles.....no codes?
