Welcome, I'm Chris (aka Moose). Experts aren't employees / agents of Just Answer. We are independent service providers using the Site to sell their Expert knowledge to Customers. I strive to provide EXCELLENT 5 STAR service, let me know what's needed from me so your pleased.

A test light is hard to get a flash from because the pulse is so short the filament just can not illuminate. A noid light is better for this test. Do you have a scan tool that can monitor the PCM inputs to confirm it is receiving an accurate CMP and CKP sensor reading?

Thanks for asking your question and letting me try to help you.

If your confused on why or how to rate me, let me know.

I'm only paid from the deposit you've made when you rate 3,4, or 5 stars.

Follow up/Reply as many times as needed before or after rating.

I stink at phone diag but you can prepay and request it and another can accept that invite if you choose.

Were you able to confirm the PCM is getting accurate CMP and CKP sensor signals?

So far it looks like we need to go over the PCM to confirm all powers and ground to it are good.
