Timing problem

[Spoolncruzn]

ok i have fixed alot of my problems and now im down to this i did all the timing steps over and over again and when i start the car and put a timing light on it its at like 20 deg btdc and when go to set it at 10 i have to pull it all the way up as far as it can adjust ? and when i drive it on 20 btdc its better then it on 10 btdc come some point me in the rite direction or what im doing wrong

Do you have t and e1 jumped in the diag box when setting the timing and does the check engine light steadily flash indicating no stored codes while doing so?

 

[Spoolncruzn]

yes i jumped them and ill have check tommrow i did sum googleing and i found sum poeple says set my crank timming 10 atdc and it will compensate for 10 degs and set me at 10 btdc is this info correct ?

 

[SC61 MK3]

No... Turn the crank until the notch points to 0 and both cam marks are point straight up. Jump t and e1 and check for codes. If steady flashing light meaning no codes than start engine and adjust cps until the crank notch is at 10

ok thats what iv been doing and if it comes up i have codes shoulde i still try to set my timing or what shoudle i do ?

you need to verify that your dampner rubber has not dried and caused rib assemble to rotate
remove number 1 spark plug
rotate til spark plug is at its highest point
see if notch aligns with 0 degrees on timing cover

Assuming you are doing it right....if you have to turn the CPS all the way to get close to 10, then the CPS matchmarks are not lined up with the engine correctly.

*rotate until piston is at highest point

A chopstick is good for this, just remove spark plug and be careful when putting it in and turning crank

When chopstick is at highest point crank should be at 0

If not remove crank pully and replace either pully or small key that holds it in place in crank

ok i redid my timing for the 100th time and i have a code 51 whats that? and when i put the cps in i took the cover off to see ware its at for tdc and no matter what i do when i put it in i cant get in line strate up ware tdc woudle b ?

yes thats what i tryed and my cps is a lil diff then that and when i let it warm up and went to set the timming same thing with all the adjustment it has i can only get to like 12 deg btdc and it runs worse on that then it does when is at like 20 25 btdc if it had a mark that far over and runs better on that my car is crazy lol what shoulde i try next

Did you ever verify that when your #1 piston was at tdc that your timing mark was at 0? (engine off)

yes my 0 mark and the line on crank r good its at tdc when thats lined up and i cant get the cps at 0 when i have the cover off checking it when i slide it in the head iv tryed the hole one click back and everthing

 

[Spoolncruzn]

but y is my car running better on 20 btdc then it does at 10 or 12

 

[jdmfreak]

I guess my question is...... When your crank shows tdc is your piston really tdc? Because if the rubber has slipped on your crank pulley then it won't be lined up and what your showing as tdc is actually 10deg before and when your running then actual 10deg would show as 20deg does that make sense?

lol i dont quite get what ur says but im sure its tdc i will check again for 101th time lol but is this a com n problem to b at tdc but the marks dont line up for it and if so how much woulde it b off

 

[jdmfreak]

Don't pay any attention to the timing marks for now... Take out your spark plug from cyl 1

Then insert a new pencil or a chopstick into the spark plug hole and turn the crank with a wrench until the pencil/chopstick is at the very top.... So either way you turn the crank lowers it farther into the hole........ Then look down at the timing marks and see what they say

I think you CPS is off a tooth. What is you engine vacuum at idle. Usually if you adjust CPS till you get 19-20 "HG your timing is correct.
