Hi everyone,

I need help troubleshooting why my engine is starting but won’t idle. Here’s a link to a video I made of starting the engine.

I did a full transmission swap and lifted the engine completely out of the bay. This is the product after I put the engine back in along with the new transmission. I believe I put all vacuum hoses back properly as well as fuel lines. Put new engine oil, transmission fluid, and coolant so the car should be running normally. Any ideas what’s causing this? Thanks.

Got fuel pressure the whole time?

I haven’t checked the fuel pressure with a gauge, but I’m able to rev it up some before it cuts out. My main theory is with the vacuum system. The engine will idle just fine with MAP sensor disconnected, but if I try and accelerate while parked, the engine will cut out immediately.
