I have these codes reading now po700 po335 and po727 any idea what to check first on 03 kia sorento. my car lost power then shut off, then wouldn't start

fuel pressure regulators are normally located in the fuel manifold. They are either vacuum controlled or electronic controlled to maintain the right fuel pressure for engine requirements and to shut off the fuel pump when the ignition is turned off
If your manually adjusted unit will not do all that then you are asking for fault codes to appear and all sorts of problems to occur

be careful on this one. 700 means a transaxle, not sure if its stopped signal or something else. 335 is the crank sensor, i wonder if you have a timing belt that has come or or somethin like that. dont crank the engine until you can get someone to check some things.

check the alternator maybe is bad and so it drained your battery, jumpped and try to started sould start

This is almost for sure the fuel relay. I do not know where it is on your car but I would look for it to be by one of the back wheels where road junk can get to it and corrode it. Once found not very expensive and very easy to replace.

this is an obd2 trouble code table, you can understand the meaning of code.
for p0335, you can try:
Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal.

If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs?

If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay?

If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault.

There has been known promblem with the 03- early 05 sorento of radiator fan staying on even after engine is turn off, it is claim to be a electrical malfuction in the engine termalstat. However you may just need to check your coolant level and fill it up as there is also a promblem to the sorento's having a leaking radiator coolant resevior too. Pretty much I own a 03 sorento, and it has been nothing but promblem, but glad I got rid of it. However like I said, check your coolant level, and fill it up with 50/50 coolant to recommended level. Should be able to solve the promblem, since it seems your engine is lacking coolant and is overheating, and the fan turn on automatic even after you have shut of your car to help cool it down.

P0335 Crankshaft Position Sensor A Circuit Malfunction

good news there is a recall on your vehicle (4WD MODULE) take it to the dealer with smile

P0355....Ignition Coil E Primary/Secondary Circuit Malfunction would suggest you need to replace your coil packs. Heat damages them after time and will eventually lead to misfire and very rough running motor especially when it's damp out.

P0700....Transmission Control System Malfunction

I would start researching the possibility of a bad ground, a loose main cable to the battery, etc. If the codes come back, the P0700 can be very serious and could require attention at a Transmission shop or dealership. There is a remote possibility that the codes are entirely unrelated.

Perplexing ... OK do the remotes work elsewhere from I'm assuming your driveway ... or do they work nowhere? (I was going on an radio interference theory here) As I've experienced this in close proximity (like 100 feet) from high power TV towers.
otherwise it sounds as they have all lost code simultaneously which has lottery jackpot odds ... Did you have a lightning strike nearby with both vehicles present? If these are OEM systems they may have to be re-activated (coded to your vehicle) at the dealer unless there are instructions on how to do this in the owners manual ...
