So I decided to upgrade my HKS 264s to GSC S1. Everything basically went fine. Put the car together, try to start it and the car only cranks but doesn't start.

Here is few checks I have done:
1. I have taken everything part again just to check if everything is tighten and plugged in.
2. The cam gears marks line up with the vavle cover marks.
3. I also opened the cam sensor cover to check on the trigger position and the larger vein is at the bottom how the its pictured in the evomoto instructions.(Note I never took the off the whole cam angle sensor assembly when installing the cams.)
4. Also changed the sparks plugs.

The interesting thing the seems to crank just fine, its doesn't start, it almost seems its just about to start.

Any ideas to check for tomorrow, please go for it.

 

did you put the coil packs in correctly. they are not interchange able, i believe

 

check and see if the coil pack are pluged in all the way and seated fully, check maf plug

 

throwing any codes?

 

make certain that you plugged the crank sensor back into the harness all the way behind the head, next to cylinder #1 injector too.

 

Your cam gears time marks line up with the ticks on the valve cover, but does your crank time mark line up?

 

Right when you posted I knew that was the problem, because when I was putting them back on for some odd reason I was 100% sure with myself how they go on, probably because it has been such long day and it just slipped my mind. So after checking the manuel and going the car, the problem was confirmed as the coils were not placed right. After the change the car started up. I tell this much the S1 cams are definately more aggresive then my old set up. Any how thanks for all your advices.

ISSUE SOLVED

 

They are interchangable, same part numbers just different length wires for the other cylinders. It sounds like the issue I had with my BC 280's. All I did was crank it every 20 mins for a while to pump up the lash adjusters. After doing so the car started. (I also had to degree the cams to get it to start better, but that I think was due to the aggressive ramp of the 280's)

 

Could you have one of the cams installed 180* out?
