Ok I can turn on my car and it will drive and run perfect.. but lets say I have to go to the gas station to pump gas or run in and out of store quickly, and have to turn off the car and try to turn it back on then it WONT start... I have to wait like at least 20 minutes before the car will turn back on... I can hear the motor cranking and I smell the fuel, but the fucker wont start til like 20 minutes later.. So now Im forced to leave the car on the whole time cause Im afraid the car wont turn back on if I shut it off.. Now If I go to a mall or somewhere knowing Im gonna be in there for awhile I can turn it off and it will turn back on like nothing.. Also when it doesnt want to turn on, (sometimes not all the times) it WILL turn on for like a second and then shut off.. Please help, Im sometimes afraid that someone will jump in my car and take off with it while im in the store

Somone told me it was my mfr-main fuel relay but im not sure. looking for somone who knows what the fuck there doing with these cars. im used to having a turn key car and i just want to get this fixed the right way.

rep will be given to anyone with advice.
