Ok, Some progress was made today - new plugs installed / got spark well on two cylinders lol Ignition 4 & 8 work fine, 1, 2, 3, 5 & 7 coil packs tested on ignition 4 and coil packs works fine It seems the plug connectors for the coil packs - 1, 2, 3, 5 & 7 aren’t connecting completely or are damaged, will inspect this more tomorrow and most likely replace them with new ones hopefully this will fix my issues... progression...

Yeah mate its so close to starting my friend - I will replace the plugs today and do as you have recommended with the fuel. I will let you know how I go Thanks Ash

This is the video that a match to the attached log - Let me know if the video worked or not. I do have spark thinking i will replace the spark plugs for some fresh ones. ( Just noticed on that video - ECU Drops and Reconnects - why do you think that is happening? )

Sorry Adam, I should of been more detailed with that attachment and what the situation was of the log That log isn’t direct to the battery, it’s on the kill switch with the rest of the components that are on I have changed the power cable to the starter to a 80 gauge to see if that helps at all as the cable I had wasn’t as thick The engine sounds middle range for speed, doesn’t sound slow enough where I am concerned In regards to turning it over by hand yes it’s got compression I will upload a recording of the log and you will be able to hear the motor turning over in the video trigger scope incoming today

Hi Adam, hope all is well & thanks for your response I will try direct start from a battery before I upload the trigger scope and the tune in the morning In regards to - battery it is brand new and starter isn’t very old came with the crate motor ( also have a brand new hi torque mini starter i can put on to eliminate starter concerns if required ) Ash

Hi, I am having some issues starting up my LS3 in my S14 and was hoping someone could help me sort this out If possible maybe by remote access to my computer to check config or I can send it to you to have a look & confirm my configuration is correct etc as the engine won’t start.. This engine and ECU combo came out of another S14 and was working fine before the removal of it so I assume the previous tune/setup is still on the ecu from what I understand I have put the engine in the car with all the loom connected to the sensors for the LS3. I have downloaded the PC Link G4 + and got it connected. Everything seems to be working, in regards to oil pressure, fuel pressure, oil temp readings etc i have been doing some reading on the forums to ensure the Ecu setup on the Ecu was correct and from what I understand and could see all seems right I have tried to crank it over and it doesn’t want to fire up, by the sound of the motor it sounds like a spark related or something stopping it within the Ecu Looking in PC Link - I have no fault codes coming up, I have fuel and I have injector tested and have readings from them and they look good i have checked the settings for firing order, triggers, Ecu, checked over most of the settings and compare to setups I seen on here for LS3 Everything looked fine from what I understood the triggers 1 / 2 work when cranking, i have checked the setup to what was previously setup and looked what other people have on the forums and all looked good there I noticed battery volts drop abit to around 9 when cranking goes up and down slightly My Trigger 1 / 2 ( V ) is 1.50 - reading up about this and this isn’t correct? My Engine speed aren’t going above 100 either and from what understanding they have to be in 150 - 500 ish mark i have been using this guide also to ensure everything is correct - https://linkecuhelp.zendesk.com/hc/en-us/articles/1500001810341-My-engine-won-t-start I get to part 3 & I can’t get the engine speed past 100 ( Engine Speed should show a value, anything from 150-500 is a good start. It probably shouldn't be over 1500, and it certainly shouldn't jump erratically between 0 and 200 or 200 and 4000 for example. ) I think it has something to do with the trigger calibration? Correct me if I am wrong hopefully someone can push me in the right direction to get her running PS- will upload trigger scope shortly Thanks In advance Ash
