Remove the Air cleaner completely and you will see the Cold Start Valve underneath with the wiring plug attached to it.
You can instantly recognize this valve from the Allen Key screws that bolt it on to the manifold.

Make sure the cold start valve is working properly and not seized up.
The cold start valve could be checked by scraping the feed wires for a 12v input when the engine is cold. Use a tester for this. Put on the key to start for a half second. If there's no 12 v in the wires, remove the cold start valve and position it onto a container of gas. Aim a jumper wire from the battery positive line but do not touch it yet to the exposed wires leading to the valve and have somebody crank the engine for half a second, at the same time, touching the wire to the battery. Gas should squirt out. If no gas comes out, the coil is bad. Replace the valve. If gas comes out, the coil of the valve is good, but the thermo-sensor is bad. Replace the thermo sensor. It is normally found screwed into the engine block and the feed wires of the valve comes from it. -rogue1man@yahoo.com
