Hard hot start.

[Kritter]

Im having a problem with my 95 PSD, when I turn it off and try to restart about 10 min later it wont fire until it cools down. It also wont start in the morning unless I hold down the throttle till it fires. Any ideas? I think it might be the IPR NOT SURE.

I would try replacing the IPR O-rings (common problem for hot no-starts) and not too expensive (about $30):

IPR O-Ring Kit (for when IPR valve replacement is not required)
(Ford) F6TZ-9C977-AA
(International) 1825806C92

Cheers!

Hopefully just the IPR, but I had the same symptoms that ended up being injector o rings. When the oil is warm, the hpop wouldn't build enough icp to start the truck, but the thicker, cooler oil would.

I ordered the rebuild kit for the IPR so I hope that works. I really dont want to get in my injectors but if I do I do.

So out comes the fuel bowl. Right?

Injector o rings. Mine was bleeding off HP oil into the fuel rail. Pull and check the fuel filter. See if the fuel is discolored.

Update on hard hot start. I had to replace the batteries last night and after I put them in it was still struggling to start. So I had the starter tested and it was bad too. So $350 in starter and batteries later my truck has NO MORE starting issue's cold or hot. Im still going to rebuild my IPR since I have the kit. Thank you for all the imput but it was the 25 degree weather that forced my fix.
