2002 7.3 died & will not start
Long time reader here, but new to post. My 2002 7.3 (bone stock) with 96K miles has died, will turnover, but will not start. Here is what happened: Went to Walmart, about a 10 mile trip ran normal. Came out of the store, started funny, but ran weird. I had a 1/4 tank of fuel as per the guage (gauge does not work 100% of the time) so I thought maybe guage was off, and pulled in to the fuel station for fuel. While fueling, the truck started making an awful diesel sounding noise, missing, blowing blue smoke, and idling very low. I jumped in the truck in hopes of reving the engine to avoid it dying, pressed the accelerator, with no effect. The truck did die, but I was able to start it. Started funny by grinding a little extra. Placed it in Drive, no throttle response whatsoever, and was only able to idle a few hundred yards where it died and has never started since. Had it towed home.
Here is what I have done:
>1st, no check engine light never came on.
>Changed fuel filter (normal fuel amount was present before I changed the filter, bowl was full)
>Changed cam position sensor with new OEM version (gray)
>Added 2 quarts of oil (was low)
>Checked all fuses under dash, no problems.
>Checked the fuel cut off switch, thinking someone had bumped my truck at the store, I felt no button, I assume it pops up when tripped.
>I do have 2 year old batteries, and currently have 12+ volts. Just to be safe, I have the batteries on a battery charger and while starting.
>Purchased AE scanner, scanner detects:
P0500 Vehicle speed sensor A
U2015 Signal Link Fault
B1203 Fuel sender circuit short to battery
P0232 fuel pump secondary circuit high
P0221 Throttle / pedal position sensor switch b circuit range
K0E0 Test: P1298 Injector driver module failure
I did suspect the fuel pump from the beginning since the engine did sound like it was starving for fuel. The fuel bowl is still empty even after repeatedly trying to start the engine, to me that is a red flag. I do not have any noise or sounds coming from the fuel pump. I did disconnect the fuel pump electric pig tail, and check for voltage. I have no voltage.
I have never had any problems with this truck (original owner) other than a few occasions accelerating from a dead stop (traffic light), I pressed the accelerator and the check engine light came on for a 1 second and I had no power, then everything was ok.
Is there a relay in the engine compartment that could be bad? I so, where? I switched out many of the relays in the fuse box, but no luck. Could the TPS cause this? Any suggestions? Becoming desperate. Thanks.
