ls1mulllet

So here's the skinny. I have an ls1 that has darton sleeve's, cola crank etc.... Got her all put together and stuffed it into the camaro, No start. The motor cranks and randomly backfires but will not run. After trying many different things, I found that my ignition timing is pretty far off, 90-180 degrees off. What can cause this? My thoughts are the builder may have installed the reluctor wheel at a wrong angle? Can the cam pos sensor cause something like this? BTW cam timing is 100% correct as I have already checked this AGAIN. Has good compression for never being fired (170psi). What are your thoughts? Anyone had anything like this happen before?

Is your reluctor a 58X or 24X? Do you have the correct crank sensor? What timing gear setup are you using, 1X or 4X?

its a 98 camaro. I have a 24 tooth reluctor wheel and the 1x cam sensor, located at the back of the engine.

Have you done a crank position re-learn?

Through HP tuners I believe the car has to be running to do a CASE relearn. I looked through the help files and it said to start from an idle and go to fuel cut in about 4 seconds. The thing wont fire so I don't think its possible to even do one.

Figured it out. Reluctor wheel was installed incorrectly, FTL.

How did you figure it out...?

Found out that timing was way off by watching a compression gauge and spark plug at the same time. From there looked at wiring and the sensor, but found nothing. Then pulled the oil pan and compared to my old engine which was out of the car, wheel is approx. 140 degrees off.

Did you ever fix it. I have the exact same problem?

I've wondered why the reluctor doesn't have a "key" on it?

He did. He stated up top that the crank reluctor wheel was installed wrong or 140 degrees off. Don't understand how so many people get these LS motors wrong.
