Three codes p0442 p0340 p0742 2006 Hyundai accent 1.6 it cranks but will not start ?

The first code is for an evaporative emission canister leak and it might be due to a gas cap. The second one is for a cam sensor circuit problem and this will keep the vehicle from starting. The third error is for the transmission torque converter.

2006 Sportage. Why does it shut down randomly?

Many possibilities. The fact that it starts right back up does eliminate some issues though. Probably best to use a scan tool that allows real time data while driving to catch the exact failure. Could be dirty IAC or EGR. Could be wiring/connection fault. Could be signs of soon to fail fuel pump.

Why would my Jeep run/idle rough, ****, sputter while in park & when put in drive it would die several times & now won't start?

its misfiring ever do a tuneup this decade?
if it flooding it will misfire, and will stall.
and will be hard to start. if at all, until all that fuel evaporates.
the operators guide covers this, flooding
cranking + WOT,
crank with throttle wide open throttle clears most flooding.
many cars do get worse parked a long time. that is what they do.
seen spark wires go bad, and TPS go bad (really just worse)
the spark wires old love to suck up water, and then short.
which engine?
Do the tuneup then use a scan tool cranking, to see if you have DTC errors.
make sure its dont flood.
do if the spark tips are soaking in raw fuel that is flooding and the test. (for 100 years, now)

Im having problems after ive driven the vehicle for about 45-60min. Then it will start to sputter and die out. It will crank and even start up sometimes but will then die out before I can get it into gear...

The fuel filter you change every 3 or 4 years
so you should know when that was done & that
is not your problem
A a bad fuel pump maybe but not related to the
getting up to operating temp then acting up
Your going to need professional help
You only change parts after you learn how
they work & how to test them & they fail
Can't pretend we are in the 1960's anymore
these vehicles are to hi tech & parts expensive

2006 hyundai sonata takes awhile to start

Could be a fuel problem. I would have someone check fuel pressure before and after cranking the engine. You may be loosing some fuel pressure back into the tank when the engine is off.

Vehicle acts like not getting gas. anymore suggestions?

May be it wouldn't be a bad idea to bight the bullet and have a shop or dealer run a diagnosis to see what the actual problem is. All of the parts you replaced could have been check to see if there where good or bad. I'm sure you have spent more than a $100 in parts already. The average diagnostic charge is around a $100.

What I would need to know from you is some specifics.

What engine do you have?
Do you have fuel pressure at the rail?
do you have spark?
do you have power to the fuel pump?
do you have power to the coil?

Since you replaced all of the above parts I have to assume that you checked for all of this?

Let me know if you have any questions. Thank you for using!

1989 cherokee dies at light

You named the three items I'd look at first. get a manual (chilton or haynes are fine for this) and a digital multimeter. Run the tests on those and likely you will find the problem. You can also remove and clean the IAC valve and passages but do not turn the valve while cleaning or it may not seat correctly.
