An accessory light was left on and the battery went dead. Car ran fine before this but now there is no spark, no fuel, but turns over fine. I have replaced the cap, rotor, plugs, fuel pump and crankshaft position sensor. Also I have swapped the ASD relay with a known working relay. Still no luck. Has anyone had this happen? What should I check next?

Hi randjen1, Welcome to 2carpros and TY for the donation

I want you to check fuse no.20 in the power distribution center if okay -remove the fuse and get a jumper wire from the battery positive post to the coil dark green and orange wire this will power both the injectors and coil and let me know what happened.

I ran the hot wire to the orange and green off the coil but nothing happened. What next? -When you did this and crank engine over do you have spark coming out of the plug wires if not I recommend you have the computer checked out
