I have replaced the GPR and checked the GPs all have continnuity.
Wait to start light not coming on.
batteries 12+V.
ANY THOUGHTS?

 

N wts means u need to check fuses and find the popes one or clean connection on ur chip if u have one most likely

 

ALL fuses under dash are good and inside engine compartment. Don't know how to check the square black relays in the engine comp. but I don't think they have anything to do with the GPs.
Are there more fuses somewhere?

no chip

 

happened to me and it was one of the big maxi fuses poped. A bad ecu will not let the wait to start light come on. Is your tach moving when you try to start it?

 

NO - the tach does NOT move

 

ok,get under the hood and check all the big fuses-your ecu is not getting power. So if all fuses are good you have a roasted ecu. Might google cps also-cam position sensor. But i think with that the wts light still comes on- my money is on a maxi-fuse

 

MAXI fuses are good. I checked them then rechecked them w/ son teaching him how to check fuses.
What is ecu? Please not the computer.

oh no - just googled ecu and it is the computer.
Saw another form that said you could replace it with any 00-03 puter and it will run better.
Is this good information and would you get a puter out of a junk yard?

 

next thing to check would be the cam position sensor.Ford had a recall on this so call and see if its been done. I have a spare id sell cheap if you cant find one reasonable. 7.3 eats cps sensors for some reason

if you need a ecu,car-part.com is your friend

The most common reason the WTS light doesn't come on is when the fuel bowl heater shorts out and shuts down the PCM... It blows the same fuse that the PCM uses. For your truck it should be number 30 underhood... it's a 30amp...

You have to unplug the fuel bowl heater first. then replace the fuse.
