First problem- Hot start
 

Hello folks. This is one of my firs posts after lurking on the forum since buying my 2001 boxster s last October


Reading the past posts has been verY helpful, thank you. I am running into my first problem with this wonderful car.

It starts reliably every morning and after sitting out during a day at work. However it will turn but not fire (frequently not always) after a stop at the store for ten or twenty minutes. The frequency of hot start problems are increasing. Again, the car will turn just not fire up. So either no spark or fuel.

Yesterday it died twice at two different traffic lights and would not start. It had to be towed home. Until yesterday it never died after starting so I am thinking more along the fuel side. The car runs fine under load and to 5-6k rpms.

I let the gas tank go ver low, 25 miles to empt on Obc right before experiencing my first hot start issue. I am not sure if it is related or coincidence


My diagnosis or thoughts are that the fuel pump met its maker prematurely (it has 61k) because of the low fuel mistake. Now the pump is getting hotter than normal and won't start until cooling off. It got worse and now having trouble keeping up the pressure at idle.

Let me know if this makes sense. I Would like learn about testing the pump before shelling out $260 for a new one and getting into the tank replace.

Thank you

I had the same problem. Replaced the fuel filter and no more issue. When was the filter replaced?

thank you for the suggestion, I do not know when it was replaced but I have a replacement one as a part of my tune up kit.

I had a similar issue with mine. It was a problem in the fuel system. I had the charcoal canister (part # 996-201-221-07) and the shut off valve (996-605-201-01) replaced.

My problem was showing up after I refueled the car when it was hot. The Check Engine Light was illuminating, but I forget the code.

Good luck.

Might want to check your mass air flow sensor. Mine had the same hot start issue and after replacing the maf it all cleared up.
