So I tore apart my honda s2000 engine and replaced the crank, ap2 valves, rering and I put it back together and hook everything up and it will crank but it wont spark. We have fuel and compression but no spark. We tested all the coils and non of them sparked. Then I got a new Crank Position Sensor because we thought that might have been the problem and it does the same thing any advice guys?

 

Prolly wiring issue. Time to whip out the DVM & check the service manual's wiring diagram. Good luck!

 

These engines are hard to get timed correctly. Make sure it’s timed properly

 

Cam timing is good?
