OK. I'm going to follow-through and spray some cleaner into each connector and use deelectric grease. Not sure to go from there. If I have the wrong ECM after following the information Gary sent, how do I get the right one? The one I purchased has part number 78426 whcih covers #E5TF12A650SA, E5TF12A650SB, E5TZ12A650SA, E5TZ12A650SB.

OK. All connectors are cleaned and greased including connectors to sensors. I also saw that there's a boot (drain) that empty's directly onto a plug connector that connects to the external fuel pump. Don't know if that was the issue regarding the pump issues, but I cleaned that connector and greased it up as well. Will have to wait until another rain (probable today) to see if the fuel pump/injector engagement issue has been cleared up. Or, I could just hose everything down again and test it out, which I'll likely do.
Seems you're leaning to the ECM as the problem with regard to pulling codes. Since the 85 second half of the year was the first EFI for the F150, would you recommend I search by the year 1986, or doesn't it matter?

So I'm a novice at this so please don't take offense to my question. Why would it be a better computer?

Hi Gary -
Are you saying I could go with the E8TF-12A650-S1C? The one I recently ordered form RockAuto was in this range #E5TF12A650SA, E5TF12A650SB, E5TZ12A650SA, E5TZ12A650SB. I also have a C6 tranny. Does that enter into the equation?

No, I'm not saying that. Not at all since I've not looked to see what that fits. It is 3 years later, meaning 1988, so may not even be close to yours.
All I was saying is that there is no -S1C or S1D for your truck, meaning no revision C or D.

Thanks, Gary. I think I found one on Car-Part.com, E5TF-12A650-S1B,101558,JRG. Must I be concerned about the tranny being a C6.

Sorry, but I don't understand the question. Didn't you order and install a new ECM with the same #?

Yes, except the 101558,JRG numbers/letters confused me. What do they signify?
