Thread: cold starting problem

Hello everyone

after changing my MAF to a new one my previus problem has solved (no power for about 10 sec after start) but now seems that I have an other issue which is independent from the MAF.
This is already the 3rd time when right after start (cold) the engine rpm goes down to 4-500 and after it stalls. After it the engine can not be started again!! I have tried everything but it could be started only by using cold start spray.
Once it starts it runs nice and as long as it warm it can be restarted without issue. The problem comes again a day or more after.
Any idea? Thanks

When I say "cold" I mean the engine has not started about a day ago. In my garage the temp is about 15 C.
The engine starts easily every time BUT after 2-3 sec the rpm drops. Sometimes it recovers and after it goes, but 3 times it stopped and I could not restart.
It seems for me that during a day or more the fuel somehow disappears from the system and even it starts no more in the "pipe" and stalls. What I do not understand why I can not start after? The pump is runing, I also tried to purge the system (work the air out), nothing.
