95 LS400 Not Getting Spark. Help!
I recently purchased a 1995 Lexus LS400 from an Auto Auction in my area. The car didn't run when I bought it and I got it for a great deal. I started working on it and put in a brand new battery, fuel pump, fuel filter, spark plugs and wires, ignition caps and rotors. When I crank the car it sounds absolutely great but refuses to fire. I know it's getting fuel but when I pulled a plug wire and tested to see if it had spark I found it was not arking at all. I cranked the car for about 20 seconds with a buddy watching for a spark and the plug wire arked one time. When it did spark the car almost started.
I know now that this is an issue involving the spark on the car. I was aware that to troubleshoot this issue it is wise to replace the plugs, wires, caps, and rotors (which I have already done).
So I'm wondering what is the next logical step if the car isn't making a spark? Are there any other parts that I need to replace/test?
