It would help if you would give a bunch of details such where you want your car to spawn & where is it spawning instead.
At a first glance, you want to spawn the car at a locator called "start". Check if the locator's position is correct in your P3D file.

In the m7 pd3 I have a start locator the position is behind homer

What type of Locator is it? Is it a Type 3?

I'm not sure if this block of code has any relevance, but I believe you should change the following block of code:

AddStageVehicle("smith_v","start","NULL","Missions\level01\M7Chase.con", "smithers");
ActivateVehicle("smith_v","NULL","chase");

to

AddStageVehicle("smith_v","start","chase","Missions\level01\M7Chase.con", "smithers");

If this doesn't fix, I suggest to double-check if the position is properly set to your locator & if that doesn't work, add my Discord at maz#4970 and send me a decompilable version of the mod so I can try finding the issue myself.

Type 3 and here's a picture of where he spawns.

I will try it thanks.

Thanks it worked.

You're welcome!
