I have a 95 sc400 that I have rebuilt; broken valve engine will crank and I am sure my grounds are all good. The spark plugs have no spark on either bank and I do not hear the fuel pump engage at all. Starter will crank the engine but it will not fire. The only wiring I have done to the vehicle is wiring in electrical fans to the ign switch. Where should I start to fix this problem? I have no CEL so I wonder if it is the ecu.
