Started with an oil leak in cam area. Removed all covers and belts before doing so I aligned all timing marks.I did also rotate pulleys back like book called for. Removed timing belt and lh cam pulley no prob. The right cam pully on the other hand has a removal buy step on inside of timing cover. Removed vvt sensor rotate cam pulley back and forth remove 14mm cam cap then 10mm cam gear bolt. Right now all timing marks are on in the same spots. Replaced seals installed all pulleys in rev of removal all timing markes still on installed timing belt tentioner. All marks still on pull pin on tentioner and rotate engine 2 full turns clockwise all marks still on. Finished installing the rest of the parts rev removal. When I turn the car over at first it sounded like it wanted to start but gid not. Now we smell fuel out of exhaust spits but will not start timing marks still on the spot. Car ran good coming in shop.

No sir I did not yet I did not think I should have to seen the car ran in the shop fine.I Have never replaced a vvt pulley on a lexus gs300 before.I have mitchell 1 but no info.I know the marks are on and understand the? Of compression test. Im 20 year ase certified 10 year mitsubishi I dont understand when I have replaced vvt pulleys on fords and hondas never had a prob.I do remember the car about a week before the oil seals where replaced the check engine light was on and the code was for vvt performance but car ran ok. I will do a comp test for you today to make sure. They said on some boards the car should still run even with vvt not working?The car was apart for three days over weakend alot of oil came out of the pully could it just need to prime?Never seen that before but maby you did. Thank you

I am having the same problem with a 99 Lexus Gs300. I changed timing belt and water pump, both cam seals and crankshaft seal. The timing marks are dead on and the car will not start. It sounds like it want to start but it wont. I am out of ideas, and advice will be greatly appreicated.
