To start off I'm swapping a z6 head onto my d15b7, everything on the head is from a z6 minus the dizzy and exhaust manifold, running on a stock p28 the cam gear is set 4 degrees advanced it will crank but not fire up, I smell fuel, I have msd ignition wires which do spark, new plugs, new gaskets, I'm not sure if I'm having a timing issue cause it sounds like it wants to start but also when I'm cranking, the ground from the transmission to the frame rail smokes on the tranny

So I fixed my smokey ground by adding the valve cover ground and cleaning up the other two but now I'm still stuck with a car that will crank but won't start, I haven't added the two wires from the ECU to the harness mount for the v-tech but I don't think that would cause it to not start

Also I swapped my original head back on and was able to get it running aside from some timing issues

Yes I'm using the belt for a z6 and an adjustable cam gear with 4 degrees of advance timing

Not sure what you mean by "0" but I set it to were cylinder 1 all valves are closed at TDC and when I turn the crank clockwise the exhaust valves open next then the intake and so on

yes I counted the teeth and copied the marks from the z6 gear and transferred them onto the adjustable one, when I line up the lines to the back of the timing belt cover the valves for cylinder #1 are all closed then when I turn the crank clockwise the exhaust valves open next, then the intake. Should it be the other way around?

Also when I try cranking the engine there will be puffs of black smoke coming from the exhaust ports on the head

Update: I was able to get the engine to start, my problem was the distributor rotor wasn't lined up with the pin for cylinder #1 at TDC now my only concern is an agressive rocking from the motor when I turn the car off
