02 7.3 shutting down

[rockhoundweaz]

I have a 02 7.3,It runs great for about 20-30 mins.Then it starts to shut down after it heats up good.Replaced fuel pump and cps.Can't figure this one out.Any help would be appreciated

when you say it starts shutting down are you saying it acts like it is running out of fuel and sputters then dies? or is it more like turning the key off?

do you have a scanner capable of watching live data like cps, icp, ipr etc...?

also what temp outside and how many miles on truck?

this all helps in giving a direction to start.

It acts like is starved for fuel.Runs great for the first 20-30 mins.then wham.I see its blowing blue smoke too so i'm assuming its a fuel issue.200,000 miles.Just not sure which other direction to take?Putting a fuel regulator on it now.

You're gonna wish you could monitor live data.
Could be a hpo issue since warm oil is thin. How does it restart when warm

I made my Samsung SGH-I997 send this.

It starts fine if i let it cool down a while.It'll act like its running out of fuel for quite a while.till it gets so bad ill pull over a shut it down.wait for 15-20 mins then off it'll go.Crazy,Can't figure this one out?

But what about restarting hot?

Same deal,Acts like it outta fuel.when i crank it hot.

[jesilvas]

These are heui injectors, so it may be a hpo issue, not fuel.
If it dies and won't restart hot then it's more likely to be a hpo leak.

I can't find any leaks anywhere.HPOP full of oil,truck full of oil,Got me baffled

When it dies, unplug the IPR, and plug it back in. Then crank it.
