Hey guess what a warm starting question!!!
I really don't think I have much of a problem, but everytime I find somebody having the same issue on all the sites, the thread ends before a solution is posted. So here we go. My 1999 f350 starts immediately when cold. After it has run for a while it has to crank 2-3 times as long to start. Other 7.3's seem to start if you breath on the key. I understand colder oil is thicker so its not as hard to keep a prime, but if oil was leaking back when I parked it, it should be hard to start cold to.
1. scanned-all OK
-duty cycle, ICP, ect
-checked with manual gauge>2600
3. Fuel pressure checked
-manual gauge (if I remember correctly) was high 50's
4. Injector O rings
5. IPR O rings
6. new ICP
8. DP tuner
10. 6.0 oil cooler
11. EBPV sensor cleaned and tub replaced
12. ATS turbo housing
13. HPOP oil level stays between 1/2" to 3/4" below the fill plug threads. Even after 2 days.
14. Ball check valve, in oil filter base, seems to be seated fine..
Any ideas on the slower starts when its warm? I also put a battery charger on it to see if that would help. Nada. Thanks John
