J.C.S

I haven't been able to fix it since, sorry for the late reply kind of forgot about this forum. Do you have pictures of the connectors you were talking about? I checked them awhile back but didn't see anything out of ordinary. Any other suggestions would be appreciated, Since my original post, Replaced fuel pump Replaced fuel pressure sensor I have tried to spray starting fluid in the in the throttle body and doesn't make any changes. This makes me believe fuelling is no longer the issue and something electrical, my MAF sensor still seems to be functioning fine. TIA

Hi there, long timer lurker but first time poster on in this page. Recently I have been working on my car which previously ran but now will crank but won't start. Background: I have a 2011 Lexus I350 that was supercharged about 9 months ago. The issue: About a month ago I noticed a considerable drop in power whilst driving back home, I had since then jacked up my car and saw that my tensioner for my supercharger pulley had been malfunctioning which is what I assumed was causing the loss of power. Since then I have fixed the pulley and ordered a new belt and it seems to be working fine. I test started my car about a week ago and it ran fine, and now it will crank and sound like its almost going to start and then die. History: In terms of what has been changed/checked these are the following: - Spark plugs & coil packs were replaced about 3 months ago - Car's engine is was changed 20,000kms ago and is due a change, engine oil levels have been checked and they look okay. - All belts on the car have been checked and when cranking they seem to working fine. - Since the car cranks and sounds like it almost is going to start I assume the starter motor is relatively okay (just an assumption) - I have tested the battery, and tried running using a jump start kit to see if it was a battery issue, saw no improvements. - After some googling saw that the MAF sensor is a common issues, has been cleaned and reinstalled saw no improvement. - Isolated the whole supercharger system and the car seems to be getting air fine, I don't believe its an issue to do with the supercharger itself. In terms of fuel, I can 1 smell that there is some unburnt petrol when I try and start the car, I can hear a few combustions but not enough for the car to actually start. I don't think its has to do with the fuel pump itself, and maybe the injectors? I am currently checking for fuses to see if anything fuel related has been blown and needs to replaced. I am also getting the car scanned in a few days to see if its pulling any codes. Any advice on what could be preventing the car from running would be greatly appreciated, as I am just lost atm. I have also linked a YouTube video on what the start up actually sounds like. Sorry for the long post Thanks in advance 🙂
