Won't start after cam install

**Bedwards** · 05-30-2011

I just got my motor put back in, got everything connected and hooked up, primed the oil pump, but when I go to start it, it just cranks, stutters and "coughs" when you stop cranking off. The cough noise sounds like it comes from the intake, but I'm not sure. Here's a video of it:

I also need help locating where this line plugs into:

Thanks guys!

not sure if im right but i can see on the supercharger vaccum tree your missing a line. it might go there. not sure though.

**blueguy** · 05-30-2011

It does.

Plug that line into the top of the blower and see how it runs after that...you've got a decent vac leak right there.

You can see the empty port on the tree it goes into in the second pic.

**GOTIT4CHEAP16** · 05-30-2011

yea thats where mines goes. The middle line in the red circle.

All of the above are right about the vacuum line, it runs ur HVAC , plug it into that tree on top the blower and hopefully blue is right about the non start, thats a nasty vacuum leak with it left unplugged.

**Bedwards** · 05-30-2011

Thanks guys. I'll plug it in and give it a try tonight. I really hope that's the problem.

**Scottydoggs** · 05-30-2011

it sounds like its back firing out the intake, have you double checked the plug wires firing order? 2 wires in the wrong place will mess you up good.

I'll double check the spark plug wires tonight. I hope it's something simple. This is stressing me out.

Hook that back up, check plug wires, check icm ground under coil packs.

**matt5112** · 05-30-2011

Car should still run with that disconnected.

if the brake booster line was disconnected it wont.

**PurpleGuy** · 05-30-2011

really cuz my camaro started with the brake booster line disconnected.

**Bedwards** · 05-30-2011

So if it won't start with that line connected, and the spark plug wires are all hooked up properly, what should I look at?

**dsmuts** · 05-30-2011

spray a little starting fluid in it and see if it's a fuel issue.

**Fivefingerdeathpunch** · 05-30-2011

how about take it one step at a time, do what we have suggested then trouble shoot from there.

**Bedwards** · 05-30-2011

Heading home now. I'll plug in the vacuum line, check the plug wires and re-connect the ground for the ICM. I'll keep you guys posted. Thanks so much for the help so far.

**Bedwards** · 05-30-2011

Okay I did all those steps. Still won't start. I am still getting that "coughing" noise out of the intake (I think). I have a fuel pressure of about 40 to 45 psi with the key in the "on" position. I also tried holding my foot on the gas, it didn't do anything.

**SnowFlake** · 05-30-2011

Are you sure your wires aren't backward? The #1 cylinder is in the front left, closest to the coil packs.

**Fivefingerdeathpunch** · 05-30-2011

everything is plugged in?

maf, map, etc etc

**Scottydoggs** · 05-30-2011

have you checked for spark yet? double checked all the grounds are bolted up? starter wires hooked up right?

in the vid the battery sounds a little weak.
