NEED HELP ASAP Q45 1997

[FAYEZ]

hello guys,

actually i came over to discuss a big problem , my car is A Q45 1997 infiniti ,it's been not a long time when i noticed blue smoke comes out from the exhaust while i warm it up in the morning everyday ,it really was running perfectly and that someke drove me crazy so i decided to do a big budget to fix everything if i would have steps ahead to remove engine's heads to change valve stem seals

i bought everything such as engine gasket kit ,spark plugs ,Ignition Coils, timing sensors,oil pressure switch, everything the engine in need it either 2 chain guide (not overhaul )i didn't touch the block or even engine's cylinders.

i can call that like a major maintenance (14 years period )it worth that ,anyway what i haven't expected has happened the engine wouldn't start to run we tried to start it up but nothing work out everything we inspected in regards of harness were conductive correctly so that we couldn't figure it out what would it be ..............?

it would much appreciated to hear from you in regard of this matter.

Thank you in advance

First of all blue smoke is usually caused by rings, so unless you changed the piston rings you're probably not going to do anything..

First thing to check is the ECU throwing any codes? That is definitely the first place to start!

we start up the engine today everything is really completely right ,we found out a huge problem in chains &timing camshaft hahaha were not setting correctly ''kind of stupidity'' so everything is ok now.
