Sorry for the delay in my response a friend is let me borrow his snap on advantage tester but I have a little to no experience with it but it’s fairly self-explanatory and it does have the oscilloscope feature. Hopefully today I will be able to successfully run the test and get back with you as soon as possible, thanks for your help to be continued

ok hopefully I can show this video of my first test on the cam senso​​​

You can see that the signal is not correct and now I’m waiting for suggestions

MoterMitch

that was a failure I'm going to get some help posting the video.

Probably don't need a video if you can get a screen shot from the scope. Most importantly, did you have a CMP waveform when you cranked the engine?

I hope you can see this from the scanner! Sparking erratically and I have fuel pressure but the NOID light and injectors don’t seem to be getting any signal??? hELP!!!

>> injectors don’t seem to be getting any signal

Try a two-second blast of starter fluid into the throttle body while the engine is cranking. Does it even try to fire?

good evening i just did as requested and the results were as i predicted, a little sign of life followed by a backfire! this is exactly what happened at the shop, and they said timing chain ,even after performing a compression test for them. compression all cylinders were above 175 psi .I put a new set of chains on and had all the techs check my timing marks.so i would be surprised if timing chain is the problem.

I did notice a lot of unusual noise coming from intake side while cranking. And i just remembered that i had the EGR valve off and cleaned the entire system to get rid of a code for emission inspection which it went the 100 miles and passed. But it wasn't long after that when the no start happened ????

hello, I just thought I would throw that out there.im also wondering if I pull the valve cover if I could set the cam in a certain way and check the alignment on the signal rotor? as I've said any help, or suggestions would be appreciated!!!! THANKS
