Alero 01 V6 GM3400 SFI Hard Cold Start
I realize this posts is getting pretty long so if you have some time on your hands please check this out, maybe you have an idea that could help. Thanks in advance!
I just got my second car. Being on a really tight budget I saw a lot of Cavaliers of Craigslist that had numerous problems so after all I got an Alero 2001 with a V6 GM3400 SFI and 180k so I'm kind of on a cheap car challenge right now.
This car has one problem that drives me crazy and I'm looking for somebody to point me in the right direction.
When I start it first time in the morning takes a few seconds ( around 5-6 ) to start and then everything is fine. I'm afraid that when the cold weather hits I'm gonna be in big troubles trying to start the engine.
Now after gets warm will start right away. Even if it's just hot outside will be enough to make it start without problems.. I don't know were to look at anymore.
I did some work to this car so far in the 2 weeks that I had it, just note that the engine had the same problem before I did all this work on it so I didn't cause it in the process .
High mileage oil change
Replaced brake fluids / throw a Lucas bottle in the transmission and in the fuel tank .
Fuel pressure regulator ( was leaking gas into the vacuum lines )
PCV Valve ( was leaking engine oil into the vacuum lines )
Replaced some gaskets and vacuum lines that were old / dry and made sure that are no vacuum leaks .
Cleaned throttle body, MAF and IAC sensors from the intake because of all the leaks in the vacuum lines .
Replaced starter ( died on me )
Checked battery and charging system and those are ok.
Replaced spark plugs with original AcDelco pre gaped and cleaned / put some dielectric grease on the wires - wires and coils looks good I may be doing more checks on that though .
I cleaned all the fuses and relays related to the fuel / ignition system from the engine fuse box and sprayed some penetrating oil on all the ground points that I saw around the engine bay.
What should I check or try next?
I tried to pump the throttle before start, and cycling the key on and off to try to build some fuel pressure because I was suspecting low fuel pressure with no luck.
Now the car does has some codes for P0440 - EVAP system malfunction and I replaced the fuel cap but didn't fix it. I believe is the fuel neck being rusted but I want to fix this starting problem before I throw any more money in this car.
The car runs great, clean idle, builds speed fast is responsive, no problems or leaks just that annoying hard start in the morning .
If you have any thought in the manner just post it, I'm gonna check everything I can . Thank's for reading this and sorry for the long post. :D
Have a great weekend!
