    CEL Code P1450

    Where are these located and can that cause a secondary issue that emulates the Fuel Pump Relay failure?

    2003 5.4 EB Fuel Pump Relay

    This morning: From startup, had "Service Engine Soon" lit up and the attached codes were read by Torque. FYI: I've been throwing this code off/on for a while now. Not sure if it's related to my fuel pump relay issue or not.

    Sorry Bedrck, I forgot I start an online class tonight so I didn't get a chance to perform the step you provided. I will get this info to you ASAP.

    Okay, I'll get this info for you at my first break.

    Bedrick, May I have the first image/diagram (CJB) as a downloadable PDF attachment like C270a is? The text is sharper and way easier to read than the one that is showing.

    In case it was lost in the mix.... 13.51v on top 12.50v on bottom Both with fluctuations of +/- .5

    I had to do rear brakes and found my multimeter junked so I'm making a run to my local Fry's a little later.

    Which OBD 2 hardware and app

    I've had a generic BT OBD II scanner with TorquePro installed on a dedicated $40 FireTab since mid 2016. No problems with either. Lately though. I've been thinking about getting BlueDriver because it's a matched set, reader and app plus it/they claim it also reads ABS and transmission codes...

    Well.... Same result with the replacement fuse box. She just cranks and cranks. Connecting the jumper again results in start-up. Ugh. Now what.

    2003 5.4 EB Fuel Pump Relay

    Bedrck, how does this one un-clip and come out? I don't want to damage it by doing it incorrectly.

    Not yet, frigging hot. Gonna wait until the sun goes down.

    2003 5.4 EB Fuel Pump Relay

    Found one And it came out of an Expy that had all the windows intact and the doors were all closed tight.

    Got the info off mine.

    2003 5.4 EB Fuel Pump Relay

    Bedrck, Quick question. Would you happen to know what size sockets and/or tools will be needed for the uninstall/install?

    2003 5.4 EB Fuel Pump Relay

    I missed this detail. Which is a very important one. Thanks for the catch Bedrck.

    Notorious No Crank No Start Solution

    It doesn't hurt to throw it out there. I'm gonna pull a part from another Expy for the short-term as I won't know it's history or dependability. I'm going to continue to research for an improved long-term solution. Who knows, I might be able to engineer that flaw out. Not to mention, it's...

    2003 5.4 EB Fuel Pump Relay

    I'm not ignoring your advice. It's spot on. I definitely will ensure that the replacement fuse box part number matches. The ideas I have with a standard but heavy duty relay is a long-term improvement over OEM if I can figure it out. Especially the ability to adjust the voltage (flow)...

    Notorious No Crank No Start Solution

    I'm wondering this. Could I just add a potentiometer like this one LINK to a bypass of the fuel pump relay circuit that would allow manual voltage control for low need scenarios such as surface street driving or stop and go traffic? Perhaps even allow one to find better "sweetspots" for both low...

    2003 5.4 EB Fuel Pump Relay

    I came across this thread LINK and please see the large paragraph under ***EXPLANATIONS*** "variable duty signal cycle to the fuel pump" which makes sense to me for fuel efficiency. Edit: I'm also trying to avoid a situation like ExpyGirl03 had where she replaced the fuel pump relay only to...

    2003 5.4 EB Fuel Pump Relay

    Thank you again because as a matter of fact, I'm getting ready to head out to Pick a Part. By the way, what do you think of the potentiometer idea?

    2003 5.4 EB Fuel Pump Relay

    So, after getting 100 miles to half a tank of gas, I realized the PCM is not just sending power to the relay but controlling the voltage therefore controlling the amount of fuel being supplied. Now I'm wondering this. Could I just add a potentiometer like this one LINK to the circuit that...

    2003 5.4 EB Fuel Pump Relay

    BEDRCK47, Question: I looked at that plug you mentioned and there is (From the top), Orange, Red, Red/Yellow. Which one of the two Reds are you referring to?
