No spark! ideas?
I talked to the parts store I bought it from and I bought the only one in stock
. He would also have to wait for MSD to deliver. He is going to see if he can get me another one to exchange from a distributer. However my MSD Opti went back in for repairs and they are ignoring me claiming they want 130 to pay for repairs when its less then 2 months old. We shall see.
Anyway here are some thing to check.
You said your injectors are not getting pulse. This means Opti is not sending signal OR yoru PCM is not grounded.
You have tried everything I had tried and it turned out it was PCM Grounding.
I found voltage on the tan and white grounded wires thats one way to tell your not grounded at the ECU.
The Ground that was not grounded on mine was the the Black with white stripe. Small like a 16 gauge I think goes down where the Passenger O2 does and it bolts to the block. It can cause all the issues your having.
The problem is if you remove it, or its odd stud connector to the block you have no idea where to put it. My friend who was helping me put it with the purple wire that was the same size going to the starter... hints the lack of results and weird voltage on grounds.
Either way Check that out. Its an easy fix and would have saved me 200.00 not to mention the rest I spent to have someone tell me about the over shaft installer for the water pump spline seal on the Timing Cover... I felt stupid.
If they so much as start to hassle me about it I am just going to return it to the store as defective and either order a new one or order a new Delphi. It ran great to work and I am about 99.9% sure it is the optical sensor at fault.
I have been working on it and did a bunch of researching and buying parts and checking parts.. The only thing I didn't check or changed was the Distributer...Guess what it was, the Damn DISTRIBUTOR. Just replaced it today and it's working just fine..



And then who knows...probably at least 3 weeks after the 5th.....dead in the water because of a
.....I mean a defective high quality, shiny, expensive opti...I mean paper weight. The Best V8 Stories One Small Block at Time
