My 2003 Kia Sorento is having problems starting. It starts sometimes and the check engine light will come on for a while, Then it won't start. It sounds like it is trying to turn over, but just never gets thee. The battery was recently replaced and it was fine for a while, but is now doing it again. I tried to have the code read on the engine light, but the techs tool would not read anything.

Hello and Welcome to Just Answer. My name is XXXXXX XXX I will try my best to assist you and your 100% satisfaction is my goal. I have been working on these vehicles for over 10 years so I am very familiar with this system and how they work. However, keep in mind, that I need some solid concrete facts/evidence/clues from you in order to give you a good answer about your vehicle. Please realize that all my answers are based solely on the info that you provide me with.Have you checked for spark or fuel pressure when this hard start condition occurs?
How would I check that?
You can use a spark tester or a screw driver to check for spark while the engine is being cranked over. If there is no spark, I would suspect a crankshaft position sensor. If you have spark, then I would check fuel pressure. You could have a bad or weak fuel pump. If this checks out ok, I would check the purge solenoid (could be leaking fuel vapors into the engine causing a hard start condition), mass air flow sensor and engine temp sensor.
