01 F250 7.3 issues after engine replacement

[dragon71]

I have a 2001 F250 that had a couple cylinders low on compression. I came across an 02 F350 2WD with a good 7.3 and 180000 miles. I bought the truck and drove it about 600 miles to make sure it started good and ran well before having the engines swapped. I had an independent mechanic shop do the swap, change fuel and oil and filters. I picked up the truck 2 weeks ago and the water temp gauge wasn't working, and service engine light on. (It's been on intermittently since I've had it for 2 years now.) I changed the water temp sender with the one from the old engine, and it works fine. (Apparently the 02 dash cluster is different, I know it has a digital odometer.)
I brought it back to the shop to have the codes checked and he came up with 1316? Injector drive module. ( I believe this code's been in there since I got the truck with 112000 miles!) He suggested taking the computer and idm out of the donor truck and putting it into mine. Went to get it today and now the water in fuel light is on, and 3 miles later the service engine light is back on. We've drained fuel out of the filter canister 6 times and can't see any water in it. Where is this sensor located? Maybe my dash cluster isn't compatible with this computer?
I've had 4 idm's on this truck since I've owned it, only 6000 miles driven. I had a Ford dealer completely test the wiring harness and they couldn't seem to come with a solution either. At that time they also replaced all the injectors, glow plugs, and valve cover harnesses. When they found the low compression I told them low compression shouldn't make these codes keep showing up. If they would have put in a new engine the codes would most likely still be there. They agreed with me. They basically gave up and said I needed a new engine.
All of the components of the 02 truck are in my 01 now. The 02 never lit the service engine light once.
Any suggestions? Thanks.

Gee, I seriously can't believe that nobody has an idea on this truck. I was told this was the place to go for Ford problems.
This truck has been in the shop for a month now. They have checked every wire from the valve covers to the drive module and they say they are good. They even called the Ford dealer who worked on it before, and they said they don't want to work on it either. They did put the original computer back in and it fixed the water in fuel light. Now if we could just get the code 1316 to stop.

Is it running ok? Also is there any kind of tuner installed in there?

No tuner in it. The truck runs fine, starts good and no blue smoke like the previous engine(s). It seems to kick the light on when accelerating the most, bust sometimes just sitting there idling it will flash also. The only thing we transferred from the old engine were the injectors and glow plugs. The injectors were new from Ford about 6000 miles ago. They buzz test good according to the shop. Like I mentioned before, the old truck this engine came out of never lit the service engine light once in 600 miles of driving it.

If it ain't broke don't fix it. I know the light is annoying, but if its working good then why mess with it and dump money into it.

But from my experience, if you get a code upon hard accel then it is usually in the hpop system. Most of the time it's the icp, but can be the ipr or the hpop is getting weak. It's best to put it on a scan tool and check the pressures.

If it's the hpop then why does it do it with all 3 engines that heve been in there? The engine that was in it when I bought the truck, the first used one which turned out to be not a whole lot better than the original engine, and now this engine besides? Has to be in the truck wiring or possibly bad injectors. Can they be bad and still pass the buzz test?

[Schnot]

Yep they can be bad even if they buzz. All the buzz test does is determine that the solenoids on each injector are working. You need to run a cylinder contribution test.

How many miles are on that set of injectors?
