Cold Weather Starting Problems
Application:
1988-89 900 Models with EZK Ignition
1988-89 900 models with EZK ignition system (B202I engine) utilize a power stage integrated with the ignition coil. The ground wire for this power
stage has a relatively long travel resulting in the possibility of enough ground circuit resistance to affect cold weather engine starting.
To shorten this ground path, a procedure has been developed to install a new ground wire from the power stage directly to the right-hand inner fender.
This procedure also includes replacement of the hard plastic cover over the coil with a rubber boot for improved moisture protection.
In case of a cold starting complaint, the procedure described below should be used before installing an LH system cold start injector kit. Also ensure that
all grounding points are clean and tight, that the charging system is operating properly, that the oil is the correct viscosity for the anticipated cold
temperatures and that the spark plugs are the correct type and heat range (NGK BCP5ES).

1.
Disconnect the 4-pin connector from the power stage (see Figure 1) and peel back the connector's protective boot.
2.
Push pin No. 2 (wire 648, black) back out of the connector and cut off the terminal. Tape this wire back to the harness.
3.
Install the new ground wire from the kit through the sleeve of the boot and into pin 2 of the connector. Refit the boot over the connector.
4.
Connect the 4-pin connector to the power stage.
