7mgte takes alot tries...

[Falken]

7mgte takes alot of tries to start it... Every overnight I try to start it but it takes like 10 mins cranking it, and once it starts it runs good and everything, once off I can turn it back on like nothing, it just takes long when the car been sitting for long periods of time. I dunno what it can be I'll appreciate all the help.

Condition of plugs/wires? Cold start injector hooked up or working properly?
Those are a few things to check..

May want to give it a compression test while your at it

Remember, there is a cold start injector time switch at the thermostat housing! Check that plug as well.

ok i got it starting right... but now it running rich, what can be somethings that can make it do that

 

[wardog]

What was the problem? Have you checked for codes if so what are they?

 

[S.A. supra]

what are your mods?

 

[modmonster2008]

leaks in the intake hose? air/fuel meter, o2 sensor, plugs and wires like mentioned above, usually the cold start switch on the thermo housing if removed will still make the car start but run at a high idle, just check those other ones as well

can it be the coil pack sequence the one that connects from the igniter

I had this problem with my 300zx twin turbo a long time ago. It ended up being the stock "fuel pressure regulator". My car would take like 5mins to crank over and turn on and it was running super rich all the time as it was being flooded by fuel constantly. Check your fuel pressure regulator and that might solve your problems.
