Hello, I have been having an ongoing problem with trying to get my kia to start for awhile now. I will start with what i know. The car will crank but not start all the time. I started going down the list of what it could be, I changed the plugs and gapped them. After that did not fix it i changed the timing belt. I checked to see if i am getting fuel and i am. One thing i have noticed is my fuel pump sometimes does not engage when i turn the key(listening for it). However, In an order to bypass the fuel pump i sprayed starting fluid into the intake and the car still did not fire, or even a backfire. This is leading me to believe it may be electrical. I checked the fuel pump relay and switched it with a new one and it still does the same thing. This isn't a problem that happens everytime i start the car so I can't bring it to a mechanic to replicate the problem. I dropped it off at a shop for a week and they couldn't recreate the problem. Once i took the car from them and shut it down, it was happening to me again. Any info on this at all will be very helpful.
