NO SPARK

If you're trying to time it - you need to have the check engine terminals jumped in the diagnostic box.

It will jump around if you don't.

Which ones do i need to JUMP. Also the accordian hose from the Maf to the Turbo is cracked at the turbo so it needs to be replaced may have a leak

 

[MDCmotorsports]

Its the same ports you jump to get the CEL to come on.

yep but i have having trouble still now the timing is bouncing from 10 to 15 at idle like it has a miss

Let us know how you fix this.
I've replaced plugs, wires, coil packs, cps, igniter, fixed connectors and still have a bouncing timing mark.

Your timing is supposed to advance and retart when running at different temps and rpms.

YOU MUST JUMP THE DIAGNOSTIC PORTS (JUST LIKE YOU'RE READING A CEL) BEFORE YOU CAN CHECK THE TIMING.

I KNOW HOW TO CHECK TIMING

While viewing the timing mark, Using the proper procedure, the mark bounces about a 3°-4° swing @650rpm idle @operating temp.

well I jumped the ports and its running at 10 on the money. I put in new wires and plugs NGK plat and I rewired the O2 due to the wires broke off no more codes but it still seems low on power and vibrates like it has a miss somewhere

Check cam timing.

Switch CPS to another. The gears on the cps may be worn causing a jump in timing.

the Cams are set at TDC but how do i tell if the crank is 180 out if that is even possible?

 

[isnms]

I have changed cps, but I have a third one coming now :x:

edit: mcpcola - I'm not going to hijack your thread. Just wanted to see what you did to fix the bouncing timing mark. My issue appears to be something different than yours. GL.

Not really. If the cam's notch marks are straight up, and the crank is right at 0 deg, you're good to go.

Thanks man I will pyshically retime it this afternoon Thanks MDC for your info and continued help on this.

 

[MDCmotorsports]

Thats why Im here man.

 

[mcpcola]

well i checked the timing and It is as close and you can get it by eyeing it. We got some parts coming and i will post when they get here Laterz
