The ECM has to tell the pulse module to engage the starter, then, as the engine starts, once 400 rpm is achieved, the EMC tells the pulse module to drop the starter.

So what appears to be the case is this:

• The ECM is not telling the pulse module to engage the starter.
• The ECM is not firing the plugs and fuel injectors (probably for the same reason as bullet #1 above)
• The problem is, you have got to figure out why the ECM is not happy.
  • If you turn the key to "ON" (Not accessory, but ON), wait 30 seconds. Does the engine fan warp up to high speed? If so, that tells us the ECM is not powering up fully. We can work on that.
  • If you turn the key to "ON" (Not accessory, but ON), wait 30 seconds. If the engine fan DOES NOT warp up to high speed - the ECM is appears to be coming alive - but there is something it does not like. We can work on that.
  • Which of these situations we are dealing with involve different paths of diagnosis. Find out which one you are faced with.
