7.3 Powerstroke Help

[huntnphool]

Ok then its beyond me - the only time mine has died in 20years / 350,000 miles it was the fuel bowl heater shorted and blew that fuse

Ya before this happened, the only time mine had died was when the fuel bowl shorted and blew the fuse..

Also I have been stalling on replacing my glow plugs, on cold mornings it takes a few cycles to fire up but always has... usually have a SES light turn on following cold/hard start that will eventually turn off after I drive 5-10 minutes.... gutless while the light is on but as soon as it turns off you can feel full power come back. I was hoping the SES light and lack of power were due to glow plugs being bad, but not sure a bad glow plug or 2 would throw the SES light...? Also didn’t think my glow plug issues would effect the truck for 10-15 minutes after it was running..  so that had me thinking possible bad injector or O-ring...?  I think these are unrelated to my no start/no smoke out the pipe issues but not 100% sure especially if it’s an injector....

 How many miles? It’s likely injector time.

 Does it fire right up if plugged in at night?

Yes if plugged in it fires up great. Well it did before this...

 If the injectors have not been replaced it sounds time.

220k. When I bought it @ 195k the guy had said the injectors had been tested and new orings.. but no paperwork to confirm that.

Ah yes true on the harness, mine would run but only one side

Is it chipped?

Not chipped... yet. Plan to tho.

It’s a 99.
Thanks everyone for the replies, I’d really like to get this back on the road! It’s hunting season!

Have you checked the camshaft position sensor? I keep one in my glove box as they are known to fail.

Yes I started with replacing that first as it was the cheapest and known to fail.  But (I knew better) I didn’t buy the OEM and picked up one from autozone...

Yes that was my first purchase.

 Tested is not the same as replaced. My money is on your injectors as to why it’s difficult to start when cold.

Mine was a joke to start cold until i replaced injectors - now its good as new.

He's already replaced it.

Also there are multiple potential causes for this. You could diagnose the problem and replace the failed part or you could throw parts at it till you fix it.

Profile says eastside. If that's east side of the mountains, I can't help. If that's eastside like Bellevue Redmond etc I can probably help. Shoot me a message.

Sob, just wrote and for some reason did not post.
Had a similar issue with shutting off and glow plugs. Also my mileage dipped.
Replaced the cam position sensor with a non OEM. It helped but would still happen once in a while. Always wondered if it were to happen at high speed. Once shut down as i am crossing a creek bed on a wooden bridge. Scared the heck out of me as, it was all ice. I got lucky.
Replaced with an OEM sensor and no problems since. Good luck.Let us know how it turns out.

Put 5 gallons of diesel in each tank. Very possible your out of fuel or the tank didn’t switch. Cheap and very very possible
