Ford has issued a service bulletin to address a Hard start, clicking noise on the vehicles listed below. Ford has determined that a defective evaporative emissions canister purge valve is most likely causing the problems.

Always ground the high-voltage secondary port on the coil when doing electrical tests and cranking. Hint: By using a ground wire with a substantial gap, the wider spark gap forces the ignition coil to output its maximum voltage and will often locate a weak ignition coil. If you have spark and smell gas but won't start from a fuel flooding then waiting overnight would clear it up. A battery with a dirty connection or a battery with a few dead cells will crank but won't start since the voltage can be too low.


9V while cranking at the coil's positive (+) terminal if your ignition switch, fuse or other connections are working properly.
All of the gauges go dark when in the ON position but if held between the on and start position they light up. The distributor is hot to the touch or the coil have melted or have melted other nearby parts. A properly flowing EACV should idle the engine when the electrical connector is unplugged and the throttle butterfly valve is adjusted correctly.
I should first mention that this is not an Audi problem, but is a concern on any front wheel drive vehicle, as well as some cars, Mercedes and BMW, which use CV joints on the rear axles. Just in the nick of time, one of our techs noted the deep cracking on the constant velocity (CV) joint boots during a scheduled service of this car.
The CV Joints are covered with a protective rubber boot which keeps out dirt, and keeps the lubrication inside the joint.

The igniter or coil may destroy itself when the high voltage attempts to find another short path to ground.


Checking the coil's resistance isn't recommended other than checking to make sure the coil hasn't shorted internally - which may harm your igniter. But by switching the ignition from off to on, the coil power will be on for a fraction of second then remains off. When the protective rubber boot splits or tears, this allows the lubrication to be thrown out of the joint, and dirt and debris to enter. One example of the technique is to press the gas to the floor and hold it there and only release it when the car runs, while keeping the rpm above a thousand. However, it's still useful for locating a weak or finding other strange readings from the coil.
Engaging the parking brake in synchronous with the pressing of the brakes, cranking the motor for the last ounce of vaccuum and down shift also helps.
A damaged CV Boot will lead to a rapid failure of the CV Joint itself, complete failure of the joint will prevent the car from moving. To minimize expense and CV joint replacement, these rubber boots should always be inspected each service for splits or tears, and replaced BEFORE failure occurs.
And you need access to the latest technical service bulletins so you don’t waste time and money replacing parts that may misbehave due to a manufacturer’s software glitch.
