well gooday folks I have a problem with my truck that I just cant seem to find the answer too I put new batteries in my 99 F-350 7.3 diesel and now it wont start turns over but wont run. I changed the fuel filter cleaned the intake filter and it will try to run with ether sprayed into the intake is there a reset outher than the one for the fuel shut off.the wait lite is also not lit also fuse #30 is not blown and the motor turns over when I turn the key and is there something else I can try?

 

Welcome to FTE!!!

There is a whole section of "Cold / Hard / No Start" threads with lots of good information, in the "Tech articles" sticky at the top of this forum. Don't want to repeat a lot of it.

Have you ever had the CPS changed? That's the Cam Position Sensor, and it's a recall item. Or another possibility...is your fuel gauge below 1/4 tank? It may be a broken pickup foot in your tank, at which point, you're sucking air. Fill it up to 1/4 or more, cycle the key (without cranking) 5-8 times to purge the air, and try it again. It will run rough until you drive it about a mile or so to purge the remaining air bubbles.

BTW...don't ever spray starter fluid into your intake, like you're doing. Not on these diesels. Also, if you've tried to start it 4-5 times, then most likely, you've spent your batteries. It takes a lot of juice to crank these puppies. You'll need to trickle-charge BOTH of your batteries before you start cranking on it again.

Lastly, provide us some information such as...is the engine turning over, or is it simply a click?

 

Are you getting a WTS (wait to start) light?

 

no? what controls that?

 

the engine turns over but wont start and the engine wait lite doesnot come on?

 

Check fuse #30, 30 amp, under dash. That supplies power to the fuel bowl heater, wastegate solenoid and IDM power relay. When that fuse blows WTS lamp will not come on. If it is blown disconnect the fuel bowl heater plug on back of the fuel bowl. The heater element can short out and blow the fuse.

 

fuse #30 not blown?

 

Swap the blower motor relay with the PCM power relay and see if you get a WTS light.

 

did the swap on the relays no change in out come still know wait lite and has the same turns over but wont run I also had csp recall done six or so months ago and it was running fine then
