Car Won't Start After Getting Gas - spin - 12-06-2012

My car will take 3-4 tries before it starts right after I get gas. It's annoying!! anyone have an idea why? thanks


Car Won't Start After Getting Gas - flash - 12-06-2012

does it matter how much gas you put in? in other words, does this only happen when it's full?


Car Won't Start After Getting Gas - spin - 12-06-2012

I always fill it up so I don't know what would happen if I didn't

DME Relay makes the fuel system do crazy things, especially on a warm engine...



Could be,

Try swapping to a 993 DME Relay. My 951 had a similar issue.


Car Won't Start After Getting Gas - spin - 12-06-2012

thanks Fox944, I didn't know you could do that. I tried looking on Ebay for one and they seem to fit several cars, I can't find a dme relay specifically for a 993:

i don't think the relay will have anything to do with getting gas.



so, again, does it only happen on a full tank?


Car Won't Start After Getting Gas - spin - 12-06-2012

i always just fill the car up so I don't know if it's only on a full tank


Car Won't Start After Getting Gas - Fox944 - 12-06-2012

No it should not Flash. But when she gets gas, she turns off a car with a hot engine. So it may not be fuel related at all, but that's when she notices it. Spin, have you tried taking your car out for a drive and then turning it off for 30 seconds and restarting without filling up the tank? If not, do so and see if you have the same issue or not. This way we can start ruling things out.


Car Won't Start After Getting Gas - Fox944 - 12-06-2012

Spin...the 993 DME Relay will have a part number that starts with 993. The OEM DME Relay that came in our 968's has a part number that starts with 944.


Car Won't Start After Getting Gas - flash - 12-06-2012

fox - i get that - that's why i asked about whether or not it was limited to a full tank. if the problem does not exist when the tank is not full, and the engine is the same temp as when she gets gas, then it is not a relay. i wanted to see if we could rule that out before drawing any conclusions.



lol - i have more questions before presenting a diagnosis, but one at a time.


Car Won't Start After Getting Gas - spin - 12-06-2012

yeah i will test that today hopefully but I'm pretty sure it only happens when i put gas in it.


Car Won't Start After Getting Gas - spin - 12-07-2012

I didn't get a chance to do the test yesterday but when I went to start it today it did the same thing it had done at the gas pump... wouldn't start right away. it was even more difficult to start it today than yesterday. So i'm not sure what's going on...


Car Won't Start After Getting Gas - flash - 12-07-2012

the long shot is that there is something amiss in the fuel system, either a return line, failing regulator, pump, clogged filter, bad check valve, etc



the more likely culprit is the DME relay, or the fuse to it


Car Won't Start After Getting Gas - Fox944 - 12-07-2012

I would upgrade to a 993 Relay. I did that 2 of the 3 front engine Porsche's I've owned. Hopefully that is your problem....and an easy fix. But check the fuse as well, as flash stated.


Car Won't Start After Getting Gas - spin - 12-07-2012

check the fuse? that's chinese to me. I know nothing about cars...

Could be the starter going bad. My starter was particularly bad when it got hot, wouldnt work until it cooled a bit.


Car Won't Start After Getting Gas - DaveN - 12-08-2012

If you accelerate hard does it stumble or hesitate? That could rule out the fuel filter without having to remove the lines to check flow.
