K&N 57-9006 FIPK Performance Air Intake System
Toyota Mechanic: Mastertech 1, Toyota Technician replied 2 years ago

Ok, then Im assuming it is cranking over, but no run, and you have connected the mass air flow sensor connector? Did you get any kind of a electrial spark from any metal contact during installing this? Take a good look at the fuses in the under hood fuse box to see if any have burned, The large ones and small ones Thanks , please advise on progress.

No electrical sparks during installation, I had disconnected the battery beforehand. I will take a look at the fuses. Any ones specifically I should pay attention to?
Toyota Mechanic: Mastertech 1, Toyota Technician replied 2 years ago

Do you have an aftermarket alarm on this vehicle? And it does crank over but no start correct?

I do have an aftermarket alarm. It does crank over, it just won't start.
Toyota Mechanic: Mastertech 1, Toyota Technician replied 2 years ago

Ok, Then check all fuses, Alarm would cancel out the ability to crank engine, (unless it is a top line viper, or others that cancel out fuel to injectors)

Fuses looked good
Toyota Mechanic: Mastertech 1, Toyota Technician replied 2 years ago

Ok. in the diagnostic test connector under the hood, Open lid you will see on under side of lid is labled, locate the FP and bat. place a jumper between these two connections (like a paper clip or wire, make sure paper clip is not a plastic coated clip) This will turn on fuel pump, then try to start engine

Still won't turn over.
Toyota Mechanic: Mastertech 1, Toyota Technician replied 2 years ago

You are saying it wont turn (I am assuming you mean the starter turns it over, but no start) Have you checked to make sure that the connector to the igniter/coil are in place? And coil wire is good, You say it ran fine before the fresh air intake was installed correct? This intake uses the factory mass air flow sensor Correct?

Ask Your Own Toyota Question
Customer reply replied 2 years ago
Correct, the starter turns over but no start. Igniter/coil are in place and coil wire is good. It was running fine until the intake was installed.
Toyota Mechanic: Mastertech 1, Toyota Technician replied 2 years ago

Have you checked to see if there is a spark coming from a plug wire? Take a long screwdriver insert the steel part into the plug wire boot and place it 1/2 away from metal surface like intake or and crank over engine and see it there is a spark.
