What to do Hyundai TUSCON 2.7 hard starting?

Answer 1

this may not be your situation but this is what i found on my 2005 Tuscon. I had intermittent starting,some days it would be fine but after letting it sit for an hour or even less it cranked but didn't start. I checked to see if the fuel pump was working and found it was not. I checked any and all fuses and everything was good. I finally checked the two thirty amp relays in the fuse box (95230-3A400) by swapping them. when i turned the key to the run position but not start position. I heard the fuel pump kick in. After turning the key to start position the engine started. I continued to start the engine multiple times and It started every time even after letting it sit overnight in twenty degree weather. I purchased a new fuel pump before i found the problem and probably will replace it even though it runs fine with the old one. Hope this helps
