Every couple of weeks the car wont start. It will turn over. If you pump the gas a few times it might start. Sometimes it wont start for a few days. It has a new fuel pump. Doesn't show any codes. It has been towed to the garage twice. While at the garage it would start every time. One garage even kept it for a few weeks and checked it randomly and it started every time. It has had a tune up and the throttle body cleaned.

I have seen problems where the key does not talk to the computer security system correctly. There is a transmitter on your key that has to talk to the antenna in your ignition switch. It can be very, very intermittent. Usually the fix is a new switch with a new antenna which will comes with a new key that has to be programmed into the computers on your vehicle. This can be diagnosed with a scanner. you can bring up the key input going in to the PCM. If the key input is not valid, the fuel injectors will not fire and so no fuel goes into the engine.

It sounds like you may have a fuel problem. The only way to confirm this is to have a qualified technician check things out at a time when it won't start. Any way to get someone from the shop to come over to your house sometime when it won't start?
