Help! Crawford power block install catastrophe (fixed!!)
 

Hey guys.

I installed a set of brand new crawford power blocks. Tried to run the car. It started and then immediately died. I pulled the manifold bolts off to check the power block gaskets and the manifold gaskets. They were good. Tightened it all back down and tried to start the car. It started and then immediately died. I then pulled the power blocks off the car. Tightened the manifold down and tired to start it again. It started and then immediately died just as before. I figure I either have a vacuum leak or I broke a wire to a sensor someplace. MAF looks good. Intake looks fine. I have a catch can so the Pcv line is not an issue. What do I try next? Other than setting crawford performance headquarters on fire?


Update:
I finally got it fixed. After I installed the blocks I decided to make sure the car ran properly before I bolted everything else down. That was my mistake. Apparently the ECU for the fuel injectors needs to be bolted down to it's bracket in order to get a ground. Once I bolted it down the car fired right up.

My anger toward Crawford was due to their instructions. They are aweful. And this install is a compete pain in the butt. In any event, lesson learned. Carry on.

Just want to thank everyone for their help. We have an awesome community here. Thank you!:party0030::thanks::thumbup:

Did you disconnect the battery between each start?

Did you reconnect the hose behind the manifold back?

I did on the second try but not the first or third. Directions didn't say to...

All I see is three hoses. The pcv, which has my catch can on it. The line that goes for the manifold right next to the pcv to brakes. And one from the intake tube that goes down to the block. Is there one I am missing?

There's one underneath the manifold.

Where? Which side? Where does it go?

Literally right in the middle underneath. If you search the fi thread it pops off above 12 psi and gives people alot of problems since it's a little hidden.

Found those two lines. Checked and clamped them. Started car and it immediately died. No codes showing.

Now what?

Setting crawford's HQ on fire? Because you fudged up an install? laughs all around.

You just made the list buddy.

Seriously, my car won't wont start. Let's be constructive.

Ok, but if you want some serious perspective- since you reverted to stock and the thing still died, something tells us along the way you've messed something up. We can count out the CPBs as culprits. It's throwing no CELs- we can also count that out to something is either unplugged or installed severely wrong. Reaper or someone else feel free to correct if wrong, but a vacuum leak would not be likely to cause the car to immediately die

A quick scan of the internet has determined this is a first reported case of CPBs causing this specific mishap on this platform. Hope you find out what's going on so others in the future can benefit

Can a admin change the title to " Help! Crawford power block INSTALL catastrophe"

Car revs to 2k and then dies. The passenger side intake valves closest to the front of the car look dirtier than the rest of the valves. I didn't disconnect any electrical plugs. I did have to pull up hard on the manifold on the drivers side to get the blocks in. If I start the car and give it some gas it has no effect. That's all I can think of...
