94' 460 ECM location
I'm not to familiar with the Fords, but I have a problem with this one. When normal driving on the highway the truck will either miss/cutout every now and then. Its not like a spark plug miss that is consistant. When under load it will happen a little more frequently. Dealership could not get to the bottom of this problem, all they ended up doing is change out a sensor. After asking around other people seem to lean towards the ECM, so as a last effort I was going to change the ECM out but am not sure where it is located on this 94 F-350 Dually gas/460 engine, any advice on this matter would be of great help....
thanks

I'm not at all surprised, from what I've seen dealer's couldn't fix a bicycle with complete instructions to follow to do so. They play around with one for hours, sometimes days even, only to give it back in the end stating something like "we really couldn't find anything wrong with it" accompanied by a big bill. Having changed maybe the odd sensor or two "guessing" at it, heck all of us can do that.
How many miles on this truck? Do you live in the snow belt? IE does it have lots of rust and corrosion? Has the electrical harness been hacked into at any point?
I take it the cap/rotor/wires and plugs have all been replaced? Known "quality" stuff put on, no "auto supper mart" stuff?
How about the TFI module, the stator (PIP) in the distributor, or the distributor? Any of it been replaced with the cheap stuff from the before mentioned source?
How about the coil?
The distributor original with high mileage? have any play in its bushings?
I gotta go out on a limb right off the bat and say from what you posted so far I don't think its the computer.
Pull the spout and take it for a ride, do the same thing?
What sensor did they replace?

As mentioned in post #1 the Dealership suggested it was the computer, as well as other researching with other sources. I am using this website as resource. I asked the question on a day I am not able to purchase a manual. Thanks for your help....

when they suggest it is the computer or from your research on it: what says computer is the problem?
usually it is not being able to read codes or fuel pump staying on.
what are the signs you get?

To be honest, its been so long since it was at the Dealership I don't recall why. Something I do know about is on my Dodge cummins when the ECM went out on it, I could still easily read codes and my lift pump was not affected. Its simply a circuit inside the ECM that got fried. I think dnar1's suggestions are good one's and I will start there. I tend to agree its not the ECM but its always good to get other people's experiences for information, so I have to ask.
