after 6 hours of pain,scratches and wounds I installed the ls6 intake, now the car won't start , I start it up and it dies it doesnt start no matter what.

I broke that ugly thing behind the intake and I'm not sure if the car doesn't start because of it !! and I don't know what the hell is it

next time I would waste a lot of money than wasting time and breaking things !

Make sure brake booster line is firmly reattached. I made the same mistake with same results. Good luck.

You broke the oil sending unit. Common thing to break on a manifold swap. The line lastcall is referring to goes from the back of the manifold to the brake booster on the firewall. Massive vacuum leak if you left is disconnected. Here it is:

That's the oil pressure sensor, you should replace that anyway since it's broken. The brake booster line goes near the brake master cylinder, and also into the back of the intake. Mine would start up, go put put....... dead.

EDIT: Tampa beat me to it, nice pic.

heh...just a couple of threads down somebody else has the same problem. The part numbers for the replacement part is posted in there too.

Looks like the oil pressure sender, but I am not sure that will cause it not to run. Mine was allready broken when we pulled my intake and it was running fine before.

yep, it will definately run fine with it broken. Busted mine on my LS6 install - I started the car and the gauge was pinned to the right Scared me until i learned it was only a dumb sensor.

I forgot to reattach the brake booster line and it ran and idled nice, but once you gave it gas it freaked out and shut off. Make sure the pcv system is hooked back up too. There is a line that goes to the front of the intake. Do you have your map sensor plugged in?

Mohammed

I'm not sure about anything , have to wait 3 more days to get back home

Mohammed

Problem solved, I started the car yesterday and it seems fine

thanks to ls1howto

I just did what this pic says

Ohhh totally man. If you didn't torque down the manifold in the correct sequence you'd get just enough of a vacuum leak to cause your problem. Good call on whosever part it was that called the call of torquing in correct numerical procedure.
