Okay folks,

I have fixed about 50 little gremlins with this car in the past few months. The (hopefully) last one that plagues me is that the car won't start in the morning. EVER. Come home in the afternoon for work, BAM starts right up. I though it was some security thing because when the car starts it drives just fine (now). No stutter, no hesitation, doesn't overheat etc. This car has new;

Plugs/wires
Distributor rotor
ECU (still thinking this may be the cause but not sure)
Fuel pressure reg
Has good fuel in it (1/2 tank but the amount never seems to effect it)

Links to the Videos of the start and not starting. There is one F bomb in the second video so pardon that.

In the morning start, try to hold down the the throttle a bit ,,, say 1/4 to 1/2 way.

If that helps look in to

Done that. I've tried every which way with the ignition and throttle to get it to start. Nothing. Turn it on a few times and off to build fuel pressure, different throttle positions, everything.

No one? C'mon fellas I need some help. It is driving me nuts and I'm sick of paying for parts that don't fix it.

Did you try checking for codes? It's pretty hard to diagnose something like this online with little info. i would check to see if your throttle body is clean and clean the IACV while you are at it.

Try turning it on with the maf disconnected, reset your ecu, do the 12v fuel ecu mod.
Are you sure its not the lexus antitheft killing the starter? Do you always unlock the door with the keys. Not the remote unlock.

No codes, throttle body is clean (took it apart). Will look at IACV

I did the 12v mod. I do unlock the door with the key, don't even have a FOB. I will try the MAF thing.
