The 3.0L engine doesn't show asd relay, according to my wiring diagrams. Note the wiring
for distributor.
The top wire in the diagram is voltage, with the key on, use a test light to check for voltage
on that wire. If no voltage have to backtrack the circuit. You have to remember, the
computer controls ground for the ignition coil. Usually the computer has to see both the
cam and crank sensor signals or it won't ground the circuit. I believe the cam sensor is
integrated into the distributor assembly. The crank sensor is separate. Any applicable
trouble codes? The distributor assembly is a common fault, but, hate to see you replace
anything and it not fix the problem? My database does have mistakes, but, it's all i have as
far as reference material. good luck
