Engine Mechanical problem
1986 Nissan Van 4 cyl Two Wheel Drive Manual 16800 miles

Truck would't start, I found the timing chain tensioner, and the guide broken. Replaced chain, tensioner, and guide. Tried to start, but no start. I checked for spark, and it has spark.I dumped a little gas down throttle body, and still no start. It just spins over, like it has no spark, or gas, or like the timing chain is broke. The engine is a Z24. What am I doing wrong?

NAPZ engine 8 plug

Maybe you got the valve timing off-Did you put engine no.1 piston on its compression stroke/TDC and line the cam and crank up before installing the timing chain

Yes I lined the crank, and the cam, up just like the book said to. Both keyways straight up, and the cam gear set in the #2 hole. I can turn the motor over, with the #1 plug out, and watch it spark. It sparks at top of compression. Am I still missing something?

The intake valve closes, then the crank rolls around to 0 on the timing marks. Then all the marks line up. Is this wrong?

Did it combust and died out?
