03 DC replaced ecm,cam,crank sensor no start
I am working on a 03 DC. Ok what I got is a 3.3 liter with 86,000 miles on it. I have no spark and no keyed power to the coil. I replace ECM, crank sensor, and cam sensor. All it does is crank over, what am I missing? Is there something I should look at? Any help greatly appreciated Thanks!

In an '03 model year, you can plug it in and have it work unless you have the SKIM system (grey headed key). If you have skim, the vehicle won't start unless you transfer the key data from the skim module to the new PCM. If no skim, the vin and mileage should be programmed but shouldn't cause starting issues.

First we start with the coil. The brown / white wire that goes to the coil is from the ASD relay. It is energized for 2 seconds when you first turn the key on and then while cranking. Make sure you have power there first. The other 3 wires are the ground side drivers that fire the coils. You want to take a test light and connect it to battery positive. Then you probe the other 3 wires while cranking the engine. The test light should flicker on and off like it is trying to fire the coils. No light or a constant light is bad. Do that and let me know what you get.
