ctubutis Posted August 4, 2018 Share Posted August 4, 2018 Well a solid resolution continues to evade me. I keep running into tests that I really need a breakout box for so I ordered one. Well 2 actually. Found a pair on Ebay for less than $100 bucks shipped. I'll be posting up the second one for sale when it gets here if anyone is interested. I could replace the ECM and TFI and see what happens, but I hate throwing money at parts only to find it's in the wiring.... If it were me, I would have swapped out the computer a long time ago.

I can look at my stuff and see if I still have a spare 1986 5.0L box, it will be from an AOD truck W/4WD, but shouldn't be an issue. Link to comment Share on other sites More sharing options...

I have one from a 1993 3.0L SHO, I for some reason don't think it'd work too well for this. ;) Link to comment Share on other sites More sharing options...
fords4life Posted August 6, 2018 Author Share Posted August 6, 2018 If it were me, I would have swapped out the computer a long time ago. I considered it, but didn't want to throw parts at it either. Breakout box will be here tomorrow so now I just have to wait for the next rain so I can do some more diagnostics. I also picked up a noid light so I can check to see if the injectors are firing or not. Link to comment Share on other sites More sharing options...

But, does Ford port-injection use the Bosch injectors? Link to comment Share on other sites More sharing options...

But, does Ford port-injection use the Bosch injectors? It was new to me as well. They make them for Ford injectors as well. The one I purchased is listed for "most" EEC-IV TBI systems. I figured for $10 it was worth a shot. I have not tried it yet. https://www.ebay.com/itm/232863452031 Link to comment Share on other sites More sharing options...
reamer Posted August 11, 2018 Share Posted August 11, 2018 I need to see if I can find a gauge locally to go onto the fuel rail schrader valve, but the last time it happened, I had pressure, just not sure how much. That and the sound of the fuel pumps running lead me to believe the issue is ignition/computer related, not fuel system related. check for gas in the engine oil, Ripped diaphragm in fuel pressure regulator and "do" this. ripped "d" can lead to pumps running, yet low pressure to the rail and most getting back to the tank via return line, but some ends up in the oil via cylinders leaking.

This should be a consistent issue though right? Not dependent on rain/moisture. Link to comment Share on other sites More sharing options...
