sorry,i know this goes in technical but no one even seems to know it exists anymore, including myself and i cant afford to keep having to tow my car.my car seems to not want to start up sometimes. It cranks and everything but it just wont start. Im sure its receiving fuel because after trying for a couple minutes i can smell gas. Could this be a sign the PTU (Power Transistor Unit) is going out? SOMETIMES it will start with jumper cables. Could it be my starter. Please help me out, ive had to tow my car three times because it wouldnt start. PLEASE HELP Thanks in advance
