Wow MV8! very detailed Thankyou so much for the time in explaining that to me. I will start those steps.. and report back. I might be pushed to get that done before I head across to Scotland to check in on my Mum for a couple of weeks. 👍🙏🙏

Hi MV8, so here is my latest update: For the first time ever the engine is now running in the car ! I did have a crank trigger welded to the crank pulley and moved the Crank Position Sensor to the front of the engine: Bingo! I do however now have the problem of a nasty noise coming from the starter motor / flywheel area… sounds like a bag of spanners rattling around! I switched the starter motor for another one… Worse! I am open to suggestions on how to diagnose exactly what that might be? I have the three bolts tight? How do I know if it needs shims etc?

Hi MV8, I was getting tired of nonsing around with ferrite beads and additional emi shielding, and have decided to go to a Crank pulley mounted trigger wheel to try and get rid of my issue once and for all. So I have some bits and pieces ordered up to make that happen. (Omex reckoned that moving the CPS that far away frm the starter should alleviate any issues 🤞) I will keep you posted, thank you so much for your help 👍🙏

Here is a vid I shot yesterday showing voltage drop down to about 11.5 volts cranking so I believe that’s plenty of juice. I am messing about with ferrite beads and adding shielding to the starter motor and CPS cable but am thinking that I should give that up and move to a trigger wheel on the Crankshaft pulley to hopefully put this to bed so that I can move forward with the build 🤷🏻‍♂️ IMG_3788.mov

Brief update: I installed the new starter motor today… and the good news that I got stat sync to come ON… but timing errors still climbing…. So I’m only HALF pregnant! so the new starter has improved things ( throwing off less emi) but I’m still throwing off enough interference to mess with the crank sensor reading ecu? Ill see what Omex suggests but am guessing I need to up my “suppression” game 🤷🏻‍♂️ IMG_3754.mov

Yes one of my favorite expressions Bill! 🤣🤣

Yes currently using 50 for Mx timing and Mx timing start.. have tried them both down to 20 and up as high as 75. I know some people have had issues with Omex getting sync because air gap between sensor and trigger wheel was too wide which is why I spent an inordinate amount of time adjusting the gap from 1mm to around 0.5 mm now…. And yes have switched polarity on the two wire sensor leads “ just in case” but but no joy. So my current thoughts are: Put in the new starter when it gets here… If no joy there… then connect everything up again and bump down hill to see if everything works… try increasing shielding on crank sensor wire even further and maybe shielding starter motor? Failing that its mounting trigger wheel on from pulley and fabricating a bracket for crank sensor for that… which is a slight pain as no one does a kit for it… ( don’t need to because the engine already has a crank position sensor housing there already

Handed across my starter motor to the auto electrical place… They are going to source a different one that fits my application. Now I’m cleaning out my entire fuel system to get rid of 5 years of crud. will keep you guys a breast of progress 🙏

👍👍

A couple of screen shots of the Omex software live readings… also… back in 2020 when I threw in the towel.. I had sent Omex the ecu to test on someone else’s car… and it came back to me as double checked and fully functional… so it is definitely something to do with me! And my setup.

Hi just to clarify your first para to make sure we are on same page.. when cranking with starter… the stat sync stays OFF…. My understanding is that is BECAUSE it’s miss counting teeth and that causes the timing errors to keep rising …. So until I get SYNC, it will not produce fuel or spark…. the good news now of course is that we know if we turn the engine over by rolling it down a hill it DOES sync…. we just have to figure out WHY the starter throws the crank sensor for a six so badly!!!! I have Jerry rigged up a home made additional shield for the crank sensor lead (it was already a twisted shielded pair from Omex…. I used tinfoil, then painters tape, then a length of wiring loom and earthed the end of it to battery negative with my two Omex ecu earth wires…. Didn’t work! the search continues.

This second vid is with spark plugs IN IMG_3540.mov

OK first vid is clutch in and NO spark plugs(fuel pump relay removed) IMG_3538.mov

Yes, exactly as above👍 no lambda sensor or shift light. Ford 36-1… no Hall effect jumper on the board installed as of course it is VR crank sensor. I will send those two videos 👍

Here is a video(volume up) of me cranking the car… (spark plugs out) stat sync will not go on … So I think that means that the ignition switch IS wired correctly as the ecu IS getting feedback on engine revs from the crank sensor?… but cannot sync and determine TDC? IMG_2927.mov
