If there were no compression it would spin easily. Jumping the battery will not make it re-charge. You need to charge the battery.

You most likely do not have some electrical component connected. Are the ignitions connected? Did you disconnect the fuel pump? How about the fuses, maybe you popped one?

Is the ECU connected?

 

fuel pump to a new one
brand new battery
i will recheck the fuses again right now. but the 20amp ecu fuses is good.

 

Check out this pdf, ignition section from the EVO 8 service manual.

I just added another pdf regarding engine assembly and disassembly.

so the question still stands.

did you get any compression readings.. and if so how much on each cylinder

 

If there were no compression I would guess the cams weren't spinning but were keep valves in their open position.

 

that and did tq the bolts to spec causing it to spin.

Either way he needs to give us a little bit more detail about his readings.. makes a diffrence if there is some compression to no compression

 

Just a little ;-)

 

no compression. period. Also the cams is spining each crank.

 

some people are telling me the CAS ? on the ix it haves 2 of them. If the CAS does go bad, would it throw a CEL ? i have no codes/CEL

 

looking down at the sparkpug whole after removing the sparkplug. i see oil. WTF

 

where are you working on this car at charlie?

 

1. Did you do any other work than the cams?
2. Does the motor/cams turn when you turn the motor by hand?
3. Is the starter install correctly?
4. Are you sure the cams are aligned correctly?
5. Did you check the spark by pulling a plug and running it out of the car?

 

cams and head studs installed. this will be my 7th time installing cams.
yes the motor does turn when turning by hand.
cams are align correctly and even if it were not, it sould still run with vibration.
yes i did pull the sparkplug/coils and tes tit ouside. all 4 sparks.

 

if you have no compression sounds like all your valves are open.. and not closing or your head is not on correctly at all ( this shedded more light as you said you changed your headstuds)

Did you tq your head to specs?
2nd did you follow the tq pattern of the head bolts indicated by the evo shop manual?
3rd. Same thing goes with the cam retainers, did you tq them to specs and did you follow the torquing pattern indicated by the shop manual?

 

yes the TQ is correct for all. like i said before this will the 7th time i ahve install cams and head studs.
