98 Lexus Gs300 Limo Hard To Start.

[gs300lexuslimo]

Hello,

I am trying to figure out why our limo is having a hard time starting. I had a friend who is a mechanic scan the vehicle and he didn't receive any trouble codes. He mentioned that the data stream was a little sluggish so he wasn't sure if that was normal or not but it seemed consistent for all the sensors. Anyway, the issue is to get the car to start I have to cycle the key to ignition like 3 times and the crank it and play with the pedal to try and get it to start. Once it is started it runs like a champ. But getting it started is an issue. Starter cranks over well so thats ok and I have plenty of juice. Tried a boost box and made no difference.

He was speculating the idle control valve is letting to much air by or maybe not enough. He is a domestic mechanic used to working on carb and mustangs and american muscle cars. He used to work in a regular shop and is trying to help me. We are both kinda stumped how there is no codes present. It makes some noise like we can hear it moving and i speculate thats normal since it is a motor. However, who knows for sure.

How would we determine if this is the issue and or if there is something else with no codes being thrown?

Any help would be appreciated.

Thanks
