Chrysler Repair: 1998 2.5L V-6: no start, voltage signals, fuse box

Question
QUESTION: I just recently installed a new motor into my 98 Sebring Convertible.  Now I cannot get the engine to start.  For some reason there is no power getting to the distributer to ignite a spark.  The engine turns over but will not spart for a start.  I am also hearing a buzzing sound coming from the under hood fuse box in the area of the ASD relay once the fuse is in place.  With the ASD fuse out and using a voltage tester, I am getting power shown in both sides of the fuse housing. How do I get around this problem because I'm totally electrically lost.  HELP

ANSWER: Hi Dale,
To start, the fuse of which you speak, is that #5 (with contacts numbered 43 and 53)? If so, the contact connected to the battery directly is 43 so it show 12v compared to chassis ground at all times. 53 should show no voltage compared to chassis ground unless some other fuse is supplying voltage to a component to which 53 is attached (and there are quite a few). Was this car functioning before you changed the engine? Do you know of any re-wiring that might have been done?
The basic idea of the ASD is that it is controlling items which in the event of gasoline being lost control of (say in an accident) then as the result the fuel pump/spark/oxygen sensor heaters/fuel injectors will all be turned off. To turn them on the ASD has to be closed and the PCM will not do that (accept for about 1 second when you move the ignition key to the run position) unless the engine is rotating and the ingnition switch is in the 'run' or 'start' position. It only knows if the engine is rotating by means of pulsed voltage signals from two engine rotation sensors, one which looks at the crankshaft at the flex plate, and one that is inside the distributor.
So please check what is happening with this information in mind. I assume this is a 2.5L V-6, correct?

How long does the 'buzz' last? Without stop or for just a second or so?

QUESTION: Hi, thanks for the quick response.  The buzzing is constant.  Yes , It is the 2.5L V-6 Motor.
I purchased the car with a blown motor.  I was told the car was in running condition prior to the motor being blown.  The owner informed me that there was no rewiring done to the car.  Someone was telling me because i changed the engine I might have to take the car to the dealership inorder to have it reprogramed to that vehicle.  I don't really see the logic to that but as stated I am clueless with the electrical end.  We have disconnected each wire and checked all the grounds and no luck of finding the problem. Shoud there be power in both sides of the fuse slot I previously spoke of? Im about running out of options on what to check for..

Answer
No, as I stated, the fuse contact that is outboard (43) is 'hot', the inboard contact (53) should be 'cold'. Another check would be at the asd itself where the inboard pin of the socket should be hot only when the fuse is inserted, otherwise not.
Do you have a voltmeter? And you are speaking of fuse 5?
Can you localize the source of the buzzing? as I can't understand what could be causing buzzing. Could it be the ASD relay itself? If so then try switching that relay with a different one with the same part number that is not involved with the engine running, say like a radiator fan relay if it has the same part number.
