ignition timing issues

[sogi99]

I'm trying to figure out my friends problem with its ignition timing. The problem is the timing is way off when my friend took it to the smog station the guy told him the timing is at 29*. I short t and e1 to bypass the efi and check the timing it sat way pass 15*. I tried moving the cps and timing doesn't even get close the marks I did the search and didn't find or might have missed a problem like this. If any of you guys can help will be appreciated. The car runs and idles fine the car just got and engine rebuilt by mechanic that has experience with toyota motors.

thanks

Did you change the cams?

Set everything to TDC 0 timing on crank align the cam gears to 12:00 position and rest CPS. Retime the car and go again.

stock cams i have to check the alignment of the crankshaft with the cam gears. Will realign the cps thanks for the replies

still the same issues I checked everything. I don't what's making the timing so much advanced I can't figure out what's causing it. Anybody that can help with the same issues and have a clue how to resolve it will be appreciated

thanks

The CPS could be off a tooth but if you aligned everything up right then you would already know this and would have fixed it.

There is not way the timing could be off this much unless things are not aligned right.

I had this problem once. I must have re-aligned everything 15 times before I got it right. Just make sure the #1 cylinder it TDC and that the cams are timed to the engine properly. Then try re-aligning the CPS. It is very easy to move the CPS over one tooth accidentally as you put it back in.
