Hey guys, I've read through about 30 pages on this forum trying to figure this out with no luck. So I need some advice. Got a 99 7.3 dually, for a couple days it died a few times coming to a stop sign, but cranked right back. Drove home the other night, everything was fine. Cut it off, went in to bed. Got up the next morning to go to work, Won't crank! Did some reading on here, bought a new cps at ford dealership (27.62 plus tax). Put it on, still won't crank! I can hear fuel pump under drivers side door running when switch is on and checked fuel stream at filter housing by turning drain valve. Don't know nothing about deisels. Any help would be greatly appreciated. Thanks, dkay

 

Dkay, do you have any lights, does your radio work, dome lights? your asking about cranking, that is why I am asking. IF all of these work, next please check to see if your battery terminals are tight. get back with us from there.

 

Check that your battery connections are clean and tight.

 

Sorry guys, I'm from Alabama. Should've been more clear. Its turning over fine but won't run. (crank where im from LOL!)

 

RPM gage move when turning over? I havent had this experience, but everything I have read, would send me in to exchange the CPS for another... I am going to look for a couple of threads and try to post them here. Give me a few.

 

Do these 7.3 engines have a fuel shut off solenoid similar to the cummins engines?

Fuel presure problem listed here.

The one I am looking for though is a guy who had some wire rubbing by the steering, ( i think ) this was also causing a intemittent, then total shut down.

This is where you will find a mess of info. Need to get back to work, lunch is over. Good Luck, let me know

 

Check your fuel filter bowl housing to make sure you have fuel.. My son-in-laws 99 kinda acted the same.. ended being the fuel pump (on the frame) was bad..

 

Welcome to the site dkay.

1st: Yes there is a fuel cut off switch located behind the passenger kick panel inside the truck. But since you can hear the pump and can get a good stream of fuel out that's probably not the issue. I would recommend pulling the filter lid and make sure the fuel bowl is full just to make sure.

How old are your batteries? The truck may sound like it's turning over fast enough, but weak batteries won't let it crank. This wouldn't explain the stalling issue though.

How old is the oil and is it low?

Do you have any dash lights that don't come on or won't go off? When the truck stalled was it rough or more like someone just turned the key off?

 

A little bit of an update...I tested the batteries and one of them is definitely bad. Pulled fuel filter lid and it is full. Oil level is ok but could stand to be changed. Dash lights seemed normal. Will replace dead battery and fuel filter tomorrow. thanks! dkay--hoping a new battery's gonna fix it!

 

Replace both batteries at the same time. Otherwise you'll be back with the same problems in a month or two.

 

Got it!! Replaced the batteries and started right up!! Who woulda thunk it! Anyway thanks alot guys!! dkay--thinking I feel like an idiot!

 

Not at all. Feeling like an idiot is when you have it towed to the mechanic so he can change the batteries.

I'd say you saved yourself from looking like an idiot.

 

I had mine do a no start with weak batteries myself. I just didn't relaized how slow it was cranking..
