all starting problems are the same checks. BASICS !
the engine cranks but wont start?
Codes - yes even if CEL is off. post ALL
spark at several plugs. yes no?
fuel pressure. post PSI.
those should should yield a clue...
Next ANYTHING not OEM suspect all aftermarket BS - ie chips, tuners, magnets, tornados, filters remote start, alarms.
then compression and vacuum checks.

He can't even be bothered to type out a question. I doubt he'll do any testing.

I am a little confused- you did scan for codes- SCAN ?
YOU DID NOT LET US KNOW IS VEHICLE stock? most likely suspect with hemi's.
do a fuel pressure test, then with KOEO observe fuel pressure drop - post results - drops xpsi in 5 min.
anything precede this no start- overheat, dead battery, stall, deep water,
check coolant for oil and oil for coolant - and ck oil for excess fuel.

What causes this oil leak on hot exhaust parts? An oil pressure switch? Check oil level it could be pouring out more than you think.
Not sure but if incorrect oil pressure because of a leak or problem there this engine might self shut down? IDK for sure on this one.
What is leaking and why do you think it's out exhaust pipe if that's what you meant? Smoke out your rear view I doubt you know where.
A reason engine want more RPM is oil pressure would go up - look at what's leaking as I think that's the problem. Out of oil whole engine will be and you wont have to worry about that one anymore!

throttle opening is giving it AIR, that's why I suggested the fuel pressure leak down ck.
understood no coolant in oil BUT ck for excess fuel- yes it overly cautious but prudent.
anything preceding? you drove last night and anything?

Back a few post you said oil was leaking ON engine. If confused where on my part sorry. Do make sure pressure at least at gauge reads properly and oil is full not with odor of fuel.
Fuel pressure test results would really help as well already mentioned,

there is no major oil components rear R/S ie sensors, filter, cooling line.
The milky appearing oil is a sign of COOLANT in oil... open radiator have a look there.
SOMETHING is missing - Did you operate vehicle last or did some one else drive it ? Funny that you drove truck all was well, this morning no start, leaking, and oil appears milky.
back to basics- spark - how do plugs look wet dry black tan OR steam cleaned look?
that fuel pressure, again...

im sorry i meant coolant.the wife drove truck last its been sitting for two weeks and ive been putting money into it.first it just clicked so i replaced starter and battery and cable going from battery to starter.so it still just clicked and everybody told me engine seized.i didnt think it did so i fooled around with it and got it to turn over.so we left town and got back and i started messing with it again,i was able to get it to start but had to keep pushing gas pedal it never ran correctly.so today i went out this morning and got it to run for about a minutethen i heard some noise on passenger front so i got out and climed under and seen the oil leak at back of engine right by where it meets the exaustor right above exaust pipe.that is the entire story.

OK, those remarks will bring this to a close right now.
Highly experienced technicians are donating their valuable time here to help people like you for free but you can't even be bothered to give them the whole story and just proceed to waste their time.
I'm sorry if I offended you but you are just wasting our time here so I'm closing this question now.
