I have spark and rpm showed on the scanner but no injector pulse with Noid light. The security light blinks before I put the key in ignition but during cranking the light stays off for few seconds and then came on solid. Unplugged MAF and CAM sensor still the same but Its start with starting fluid. The scanner won't communicate with the ECU so I used EOBD and it showed codes for both Knock sensors.

I would start by checking the fuses #13 and #40 in the left side of dash fuse panel to the OBD2 port and it wouldn't hurt to check all of the fuses.

Here is a guide to help:

If the fuses are good, it sounds like the ECU has gone out here is the location and how to replace it in the images below. You can get a rebuilt ECU by searching Google or Ebay. Please let us know what happens.
