So I an evo 3 from a reputable importer. Test drove the car, let it sit for a few hours and then drove it onto a trailer and drove it home. When I got home, it cranks but wont start. All the fuses are good. I sprayed starting fluid in the intake but nothing happened. I dont understand how the car was fine when I drove it onto the trailer but now it's not.. Any ideas?

 

Check for spark if it's not firing with starter fluid cause it should at least hook up to burn that off.

 

It has spark and fuel. Just tried new sparkplugs and still nothing. Starter fluid did not change anything. I am out of options....

 

If it has Spark and Fuel all that is left is Air.

I am not familiar with the Evo 3 so ignore me if my answer does not help, MAF sensor? or possibly a disconnected intake like, intercooler piping?
