2000 PS wont start

[chrisgrant91]

im working on a 2000 powerstroke. the wait to start light will not come one and it also seems like its not getting any fuel. the owner says that the fuel pump doesnt make a sound when you cycle the key like it normally does along with the passenger air bag. any ideas?

does it have a chip?
also check fuses. no WTS light means the computer is not powering up.
also a possibility of a bad sensor.

 

[chrisgrant91]

no chip. and the fuses look good. it doesnt seem to have power to the fuel heater and whatnot fuse with the key on or off

 

[93turbo_animal]

did you check the fuses under the hood?

 

[chrisgrant91]

all fuses and relays seem to be good

possible ignition switch?
dont make sense no power at fuel heater.
check ign switch
then start unplugging APS, ICP, CPS< MAP< BPS<EOT, and see if the cpu comes to life.

 

[chrisgrant91]

if i unplug the cps will it allow the computer to fire up? and what are the others you listed. i dont know what they stand for.

aps accelerator pedal
icp injection comtrol pressure
map manifold absolute pressure
bps back pressure sensor

Check the PCM relay. Do the relay swap. Swap one relay for another. It should power up.

The other culprit could be the fuel heater. But that would be a bad fuse.

 

[chrisgrant91]

i did the relay swap and that didnt work either

ok heres the low down. i need help! i scanned it and all i got was FAIL. well the guy says the cps sensor was replaced last summer or 2. not ruling that out. i tested all the fuses and they tested good. swapped soleniods and everything was good. i cranked on it somwhat and im pretty sure the fuel pump was running at one point so i would say rule that out. i also unpluged the cps and tried turning the key on and still the same no wait to start light or anything (i dont know if that would of told me anything or not just tried it) i also noticed that when i crank on it the tach does not go up and idk if it should or not. help please! im leaning toward the cps

With the CPS unplugged the tack will not work. The tach get the signal from the CPS. If it's plug in and you don't get a reading from the tach. Change the CPS

If you have no wait to start light. No other stuff is working then it would be a computer problem. Either no power to the computer or the computer died.

Unplug the fuel heater and change that fuse.

 

[chrisgrant91]

well i tried a new CPS and it solved nothing. idk what the next step is.

start checking for power to the pcm etc
