starts and stalls after cylinder head change
Just swapped out my cylinder head. Got it all back together, and now it won't run. It will start, but immediately stalls. it is acting like a huge misfire. I have battery and fuel , --fuel pressure release valve shoots out fuel when I press it. My first thought is a installed the pushrods wrong, so that is where I am going to look first. Does anyone have any other ideas? thanks

I went back and thought of everything I did step by step....wondering if this screwed something up--It said to bring #1 piston to top dead center, which I did, but I did it right before I put it back together, not before I took everything apart. Could this have cause an issue not doing this from the start?

it's a 2000, so no wires to cross for a misfire.....when I try and start it, it cranks, starts to run, shakes violently, then stalls.
in the Haynes manual it says to bring the #1 piston to "top dead center". I did this, but did not do it before I took everything apart. I did it before I put it back together. Not sure if that messed something up.
In about an hour I am going to go look everything over again.

I didn't bring the motor to TDC until I had the head installed and the rockers/pushrods back in. I don't think it matters though. The FSM says nothing about putting the engine back to TDC before installing the head.
Did you label all your connections? Are you 100 percent sure that you didn't miss any connections or switched an injector connection?

ok. got it running...I'm a big dummy, I missed a spark plug with one of the boots. thanks for everyone's input. .....Now I have smoke coming from the exhaust manifold. I think it's because of the new gasket.
