Stalls then wont restart for 20min

[dereku]

Hi i am new here i got my truck from my father when i was 16 it is great (1996 f250 7.3 of course) i've added a banks, turbo, intercooler, 3.5" exhaust, ottomind chip, trans chip, banks gauges, a stage one trans upgrade, dana 60 front axle, 6in lift, 33" tires, an airfilter off a semi (950 cfm), cat eliminator pipe

Now i had a sputtering and dying problem for the past few months, it only pops up every few weeks. im a big diesel fan so i did all the work my self, including changing the cps, whole wiring harness, fuel filter and housing (for other reasons), valve cover gasket, but not the internal wires ran out of money. This all started after i blew a hole in my oil pan off roading and too it to a shop, they pulled the motor to change it and ever since it hasn't been the same. still has all the power it did except it dies alot. i think they could have cleared the codes and fried my banks chip, but yet i still have alot of power, no black smoke ever since i got the new airfilter though. i didn't put the sensor that went into the airbox back in though, it looks like a temp sensor, wondering if that could be it. thanks alot, Derek

That is the intake air temp sensor, for the CPU, your problem sounds like a CPS, but I am not a tech. I'm sure one of the guys will be along that knows more about it

My first thought is a CPS too, but maybe one of the techs will be along shortly. Also, when you get a chance, get some pics up and some info in your signature. Good Luck with it.

since you have stated the CPS was already changed.....we are going to assume for now that its ok....

Ive got a sneaking suspition here...i have seen this before. When they changed your oil pan, if they did not use the right kind of silicone to seal it, the silicone will actually react with the oil and cause the oil to foam. That causes air to get into the high pressure oil sustem which affects the fuel delivery. Try to find an anti-foaming agent and put it in the oil and see if it helps the problem. Also, run your oil level for now so it is barely over the minimum line cold. If eitehr of these help the problem i would be taking it back to the place that did the oil pan and telling them what they did....

Ditto to Marc's post. My first thought was either CPS or Oil Level. I had a BIG problem with my truck about a year ago not wanting to run when cold...would shut off a little after I got going and then not start for a while. Turned out that my oil was low. I changed the oil and no more problems. I would check the oil levels like Marc said.

you see they used really crappy oil and it did foam alot, so i changed it and put in diesel specific oil and just to be safe some anti-foam. However when it stalls is i switch the relays under the hood it seems to run again for awhile. So today i stole my dads horn relay and it hasn't died in 100 miles which is pretty good so far. And as for the oil pan they used black RTV, its the anti-oil kind so i think that is ok. And thanks alot you guys.

No problem dereku, keep us informed, and don't be a stranger eh.
