Could not see plugs but wiggled wires and smacked the tank a few times upon spraying some more starting fluid it did run for couple of seconds more than the other day but wouldn’t take any gas when i pressed The gas pedal. Really sounds like it wants to kick over though.Wires seem to go up into the body? See pictures. Thanks

Is there any thing else to check before I as a last resort have the pump replaced? Thank you

No, don't throw a fuel-pump at it yet. Take fuel pressure readings to verify this is a pressure problem. Assuming it is, when was the fuel-filter last changed? But at 80K miles, a clogged filter doesn't seem likely. The pump is powered by a Driver Module. I have seen several threads over the years where that Ford fuel-pump Driver Module has gone bad; they don't seem to be very robust. There need to be some electrical tests done at the Driver Module. I would need somebody to post electrical schematics to try helping you do those tests.

However, it sounds like you would have a shop do the pump replacement. Is that correct? Any responsible shop would do the above tests before changing a pump. If it is going to a shop anyway, leave it all up to them.

PS: That electrical cable may seem to "disappear" into the chassis, but the connector must be accessible down there somehow. Can the cable be pulled out of the hole in the chassis a bit?

Fuel filter was changed within the last 3 years (motorcraft).

I would very much like to do it myself, whether it is the pump, module, pressure regulator or something else. Going to a shop would be my last resort.
The more I think of it the wiring might be tucked on top of the tank itself, but didn’t think to try to pull on it while I was under there.

I appreciate whatever direction you can point me into next.

OK, I misread your intentions. I will be happy to try helping this as a DIY effort. Check for that connector (two actually, I now think). and check the fuel pressure. Your favorite FLAPS will loan a fuel-pressure gauge, if you don't have one.

I think that Driver Module is located at the top=front of the radiator shroud. See what you can find there and post some pix.

Do you mean The connector on the fuel pump/sending unit combo? If so, I assume it is just tucked under between the tank and The chassis? I will endeavor to pull it out and see what I can find.

One more thing…I have a scanner that reads codes/ resets codes, shows data. All in all kinda basic. Is there a specific type of scanner that can help (I know it will be $$$) that I could/should use in this case?
I don’t mind buying a tool if it can help in the future.
If anyone has any recommendations I would welcome them.

"Do you mean The connector on the fuel pump/sending unit combo?" Yes. The fact that they are separate connectors lessons the chance this is just a matter of "the" connector not being fully mated; thus killing both the pump and level sensor. But check anyway.

Standalone scanners are handy, but can be pricey as you suspect. ELM327-based links to your laptop/tablet/phone are much less expensive (<$25), but will have more of a learning-curve since they are menu-intensive. I can't really help you select either type of equipment. I hope "nickb2" offers some opinions this weekend.

Hi,
I just want to update in what I’ve done.
Replaced the FPDM …Sounds like it wants to but still no start.

I was unable to test resistance on pins as I don’t have access to an ohmmeter at the moment.

I do have a fuel pressure tester, but since there is no Schrader valve, am a little unsure as to where to get reading from.

Did scan for codes and got a PO191 Fuel rail pressure sensor A circuit range/performance,

as well as

PO191 Fuel Rail Pressure sensor A circuit range/performance (pending)

Wasn’t able to plug/unplug the wires under the chassis for the fuel pump due to the heavy rain we’ve been having.

Thanks for your continued assistance

I urge you to continue looking for the port to test fuel pressure. My (limited) experience is that Ford hides it, but there should be one. After we verify fuel pressure is low, we will need an electrical schematic to determine why the pump isn't operating correctly. If nobody here posts such a schematic, you will have to splurge on a manual or Alldata subscription to provide that. I will be unable to help any more without the schematic.

Hi Bill, just wanted to let you know that I went ahead and changed the fuel pump and she started right up. Thanks for your help and giving me the confidence to change the pump on my driveway on an incline. Be well.
