Changed Timing Belt, won't start now.
2005 RX330 162k miles, changed timing belt, vehicle running before, now won't start. I made sure both cam timing marks were aligned and crankshaft sprocket was aligned.
fuel pump runs, has spark on front three cylinders have not checked rear yet. Security light goes out when key inserted and no codes stored or found. Plugs wet with fuel, even tried shot of starting fluid to no avail. I am bald and pulling my hair out. Any suggestions or help appreciated.Also idle control valve ok and functioning, as still won't start with part throttle. Thanks, Todd
Double check all electrical connections that you might have taken loose or might have bumped loose.
Hate to say this but if all else seems ok double check the timing belt and timing marks. And at least that's not an interference engine so if for some reason timing has jumped you will be ok.
You have to be careful to align the crank and cam shafts correctly at top dead center (start at rear pulley, align that one on the belt mark/cam pulley mark, and work counter clock wise around to the other cam pulley).
Thank you very much, cam sensor only thing I haven't checked as assumed with spark and fuel it was ok. Plan on rechecking timing marks and put in new set of plugs. Greatly appreciate your prompt help.
My thinking is that if you have fuel and fire then it must be a timing issue. (since timing belt was just replaced) Maybe not but if mine that's where I would look next. Good luck. Keep us informed with what you find.
I went clockwise from the rear . The only mark I could find for the rear cam was a line on the tab that stuck up and the front cam had a notch. Did not see any marks on belt, but with tensioner installed all three marks lined up. The marks were aligned before I took old belt off and if any moved I did put them back in alignment. And I ID'd the cam timing marks with a felt marker to highlight and eliminate error. Thanks again.
It was a lazy starter before and had what appeared to be original Denso plugs, car is new to me only owned for a day but have worked on cars for 60 years building race cars.

That is exactly the way I did it. The last diag. on bottom of picture is what I saw and aligned with. Thanks.
http://youtu.be/DI60MOkf168 -- check this out. Not same model as yours but marks are the same I think.
Sounds like you did it right. Good luck. Let us know what you find.
We just did a compression test on two of the front cylinders. 130 lbs each, cold, no oil and maybe washed down with raw fuel. Kind of low so maybe the timing marks are off as in???? slipped.
Howdy, timing marks are all lined up with picture G00013763 no start last night. However, noticed today that engine does not have 4 bolt sensor as depicted in photo under box wrench. This engine looks more like G00013764 and crank timing mark actually is at 3 o'clock. Which means currently we are out about 90 degrees on timing. Is this Possible? We used wrong photo? Plus we never filled radiator with fluid because we wanted to test start first and never got a fart out of engine. Again, fuel, spark, no start. Just wondering if there is a water level sensor that might prevent no start , when timed according to bottom photo. thanks and waiting for advice.

Took a week off to do some target shooting on my range, Todd left for home today and I'm back working on the Lexus. Found some interesting tricks. Rear bank cam sprocket has a flange so the tie wrap trick to keep the belt from slipping will only work with a wood or?? shim under it. The timing marks on the belt really are a big help. A disc break spreader tool will compress the tensioner enough to slip the pin back in so it's easier to remove the tensioner pulley and then the tensioner. I'm removing parts to install new plugs in the rear bank and to check number one on TDC. Later.
