Starting problems

Post by fgfournet »

'01 ITR B18c5
98 spec itr base map
w/ inverted purge valve
(spunkster's cal. post)

I've had my S300 for about a month now. It's starting to get hot and humid. In the afternoons I'm having trouble getting my car to start with the S300. I need to rev to 2000rpm for about a min. so that the car will stay running by itself. If I don't do this it will die immediately after initial start up. I also have problems getting the car started after refueling. The last three times I refueled the car had similar symptoms as the initial start up problem. The last time I filled up I reved to 2000rpms and waited until it would run by itself and then began to drive. As I left the service station the cars rev limiter was set at 5000rpms and the check engine light came on. Fearing something bad I pulled over and reinstalled the stock ECU. When I got home from work I reinstalled the S300 and the CEL was gone and the calibrations were back to normal. Car still running fine. I apologize for not having much more info. Next time I go to fill up; I'll bring my PC so I can check more in depth. Does anyone have a problem similar to this? Any suggestions as to the problem? Thanks.
Once I get the chance I will let you know what the CEL was.

I will try. I noticed when i datalogged the startup, the ing. graph goes up to 3 and drops out. During normal start up it goes to 32 drops to 24 then a second later to 22. Is there a sensor that reads something during refuel that could mess with ing timing? From above did you have this problem during refueling or all the time?

only when refueling and on some startups (can't recall).

But that purge valve is what's causing it. I unplugged it and never had the problem again.
