Hey Guys, I have a stock 2000 JDM Toyota Altezza and I am experiencing a no-start condition. The car will only start/kick over if it’s been sitting for a few hours and only once. Any consecutive attempts does not work. I have gotten it started and held at 3000 RPM, but after about 15 seconds the engine suddenly shuts off. While it ran, everything was smooth as can be expected. This problem was initially noticed 6 months ago when the engine would misfire and shut off randomly, but I would still able to restart with some effort and carry on normally. This happened a few times within weeks and disappeared for months, until one day a few weeks ago. The engine died while on the road but I restarted with a lot of effort. It was misfiring so much that I eventually had to get it towed back home. The misfiring is noticeable with a higher engine load and will come and go regardless of cold/hot engine. Things I have checked: - Battery is new and put on a battery tender - No CEL - No blown fuses - Compression tested normal for all cylinders - Starter cranks normally AIR - MAF sensor provides a reading over OBD. - Unplugging MAF yields no difference - Vacuum tested normal - ethrottle body responsive and tracking input x Catalytic converter not yet inspected for blockage EFI - Fuel pump newly replaced as repair attempt - Fuel pump audibly works during start attempts x Injectors not checked but unlikely IGN - Spark plugs slightly fouled, coated with fuel maybe from all my start attempts. - Spark plugs appear to fire, but only once per cylinder per attempt - Ignition coil replaced 6 months ago, no sign of excessive wear I am running out of tricks and am now wondering if there is an issue with the crank/cam angle sensors, or them being out of sync. I have manually turned the engine to TDC and the cam gear/crank pully indicators line up with their respective markers, so I don’t think there’s a physical alignment issue. I have probed all three sensors with an AC voltmeter while hand cranking the engine and I do get a noticeable response from them when the engine turns. Please let me know what you think. Thanks guys.
