Correct no power to fuel pump. No power so no clicking buzzing or any sound. Drained the fuel bowl as rvtech said and it's not filling back up. At lunch I'll go disconnect the wire and test it again. Double check the ground connection.
Also..will a failed fuel pump cause the wts light from lighting up..I know everyone keeps saying fuse 30...check fuse 30....I have checked a dozen time it's not blown. I have check all fuses and the only fuse I found blown was my auxiliary power plug and I replaced it..
If the WTS is not illuminating; either the PCM is toast or there is a power supply problem. Most notable is a blown fuse. Often caused by numerous things. ie: Fuel Bowl Heater. Have you done any work on the truck lately that preceded the issue?
You MUST pull every fuse and ensure each one is good. Even jumping a mini fuse will sometimes be a false positive.
I didn't notice the particular truck. Post the year, model, sub model and options of your truck. ie: 1999.5 F250 Crew Cab, 4x4, Lariat so I can pull it up and get you a wiring diagram.
Right now I have no power to my fuel pump..no fuel pump no fuel to engine. I'm working on getting power to it. Fuse is good. I'm at oriellys replacing the fuel pump relays now. See if that works. After I get the fuel pump working I'll tackle the wts light.
I just bought the truck 5 days ago so I haven't had time to do anything to it. I do know that it has a dptuner(disconnected)exhaust and upgrade Turbo pipes and 4" lift(I believe it's a 4")
That is not a fuel bowl heater feed wire, it has a small connector on it. That is, however a large feed wire for something like glow plugs but I see some wires coming off of your glow plug relay.
Edit: You can see your bowl heater feed wire down low on the bowl in the back of it.
Edit: Another edit, that might be the feed for your intake air heater (AIH), which is typically disconnected. I can see the stud for the heater sticking out of your spider right on the other side of your hand.
I think you still need to check the cab fuse which powers the PCM relay in the engine. The reading shows the PCM giving the ground signal to the fuel pump.
The arrows are not mine but part of the thread I found..
Try going through this troubleshoot I found on the net:
Thank you for that usaman..however I'm no electrician and I have no idea what that says..but since i am having multiple power issues i.e. No power to fuel pump. The #3 fuse which I believe control the obd2 port and the cigarette light as well as the fuse to the power point have both blown out. I'm going to replace the PCM and go from there. I have noticed that after removing the PCM my ses light has gone off but still no wait to start light.
The cab fuse you refer to is the #30 fuse. It looks good and tested good. I have not blown that fuse as of yet
2 questions
1...is there a way to test the pcm
2...and if I take it out of the truck overnight will it reset itself..I was thinking maybe I hit the dptuner button causing it to act up. I did pull the battery's out Sunday night for an hour or so when is replacing them which should of been enough to drain power to all items.
Using a Scantool or Bench Testing Unit. But, from your writings, It probably won't connect with the PCM. You can check the 12 (+) Pin in the Harness to see if it's getting power. I'll look up the pin# for your truck.

No, there is nothing to "reset".

Many DP Tuners have a No Start Selection. Perhaps, it's in the No Start Position. But, that would not cause the WTS not to activate. A defective or non-powered PCM will cause both the Glow Plugs and Fuel Pump not to get signals to operate.
Have yo attempted to start the Truck without the DP Chip Installed?

Unfortunately, these systems are not write compliant as there is no 0xy Sensors or such.
Use my light tester it lights up on plug #16 on the DLC. I'll check the pin 71 as soon as I get the PCM off
I just hooked up my volt meter and it getting 11.98
Have yo attempted to start the Truck without the DP Chip Installed?Yes
Update...I'll have to wait till tomorrow when I get an extra hand to hold the PCM harness so I can plug my volt meter in and read pin 71 see if its getting power. I do know if I have the PCM connected I get a ses light but if it is not plugged in I get no ses light. Makes me think it is getting power.
What a pain in the *** to get to that back bolt to unscrew the harness from the PCM. I read 3 bolts..yeah 2 easy ones in the cab but nothing about the bolt from the engine bay side that impossible to get to unless I used a step ladder ����and no fingers. Had to find a small woman to get her hand in there to unscrew the that bolt.
