Right....I have a strange problem which is intermittent but causing me grief. I have had the Hass installed for a couple of months now. Most of the time it runs like a dream (including a 500 mile trip to Anglesea and back over Xmas). But I have had a problem with the car just not starting. Each time it seems to be after i have filled up with petrol (not conclusive). I have a check light which I have read as P1305 and P1315 EGR Calibration Low and persistant misfire. Probably linked.
I have solved the problem in the past by unhooking the emanage, reconnecting the stock loom and restarting the car with no problems. Then reconnecting the e-mange back in and again running with no problems.
Today the car started, ran at idle, warmed up then stopped, and wouldn't restart. That's when I read the check codes with my car-pal.
i can't see any obvious problems. Any ideas?
Most odd, not something I have come across and not something I have seen reported over at SC either. Some 2ZZ conversions have issues with not starting after a fuel fillup though, I wonder if it's related?
are you filling up right to teh brim?
when teh pump cuts off do you put any more in?
not a similar problem to Dans is it?? he had problems with misfire, didn't he and it was linked to a bad solder joint?? could be causeing a resistance problem and the e-manage is shutting it down as a protective measure
just a thought
Yep I normally fill up to the brim. As I always have. This tends to happen after I have driven from the garage a good distance as I did coming back from Wales (approx 150 miles on filled tank) and parked over night. Though once the car died 200m from the garage. That's why I'm not sure if it is the filling up. Do you think there is a vacuum leak? Looking at advice on EGR Calibration it says a leak or a sticky valve can cause the stalling at low idle.
Also why does the car work perfectly when I take out the e-manage from the loop, then work perfectly again when it is replaced?
Also once I get it all going again, I don't seem to have problems til after another fill up.

There are several guys having the same issue in SC, here's the first two hits:

well my gues was going to be something to do with EVap as it's that hose that we tap into for the boost reference.
and since the SC concensu is Evap related as well, seems likely.
however I'm not sure whay/what the specific problem is.
Chiming on on the fuel tank vacuum idea. I think that's the right track. Something to do with evap system. When you remove the gas cap BEFORE filling up, can you hear air being sucked into the tank? If not, that would be a big clue. After fillup, the stock ECU (and Power FC, too) will see that there is no vacuum in the tank and try to evacuate it. It made the RPM surge like crazy and then fall off and stall the engine after doing the 2ZZ swap. I gave up trying to fix mine and just removed the rubber hose that went one of the "hard lines" on the left of the firewall. SC is down right now, so I can't link to the topic I made. The title began with "Stupid". Stupid 2ZZ fill up problem... or something to that effect. Since this happened right after the engine and ECU swap (with wiring changes), I'd say something is either wired wrong or perhaps a component of the Evap System went bad. Maybe the vacuum switching valve.

Seems to work for me...
"Stupid 2ZZ gas fill up quirk", it's the 2nd link in my post above s;) ;) s;)

I suspect the cause of this is the solonoid that is normally clipped to the rubber 90 degree hose between the airbox and the throttle body on a stock car - the ecu opens it at idle (and when the throttle is close during normal driving) to apply vac to the tank. If the other end of the hose doesnt go to the tank anymore then you will get copious amounts of air being introduced post MAF (and TB) resulting in the engine running very lean for a few seconds before either stalling or the ECU modifying the fuelling based on input from the O2 sensors (and probably throwing a couple of CEL's for good measure).
HTH
I didn't have that hose connected to the intake for about two years, including the time I first started experiencing the problem (recently). It was totally out of the picture. I removed the rubber hose going to the left-most hard line to fix the problem, but there is probably a better solution, like replace the VSV. This would do me no good, though, because the other hose from VSV to intake has nowhere to go on the intake.
I'd check the other VSV near the head, too, which is connected to one of the other hard lines. Don't know how to test them. Consult BGB.
Latest... travelling along the M3 at 80mph engine stops running and I cruise to the hard shoulder. Luckily I have my pocket PC and OBII carpal and read the check light as persistant misfire and clear it. Turn the ignition over a few times with a bit of gas and get running again. I think it is definately a fuel tank pressure thing, as I filled up this morning and there was no hiss when I removed the cap.
remember teh missing plastic reducer?
we wrapped self amalgamating taoe around rhe brass fitting and clamped the hose over it tightly.
I wonder if the fuel vapour has eaten teh tape and you have a vaccuum leak.
any siymptoms of a boost leak?
I don't seem to have any boost problems.
