Having read all I can find on this problem it seems quite common. The descriptions given are always the same, Heat makes the sensor act up at first then finally it goes open circuit and the engine won't start. I tested the sensor by first putting the ohms meter on it, 385 ohms,held it in my closed hand with meter probes in place and watched the ohms rise until it went open circuit.Put it in the fridge for 10 mins. it came back again once or twice but now its totally open circuit.Red light Codes in the computer of the LTD steady "W" & flashing "0" & "3" which is exactly what the book says to look for,Crank Pulse Sensor. For the record since there has been some confusion in the past about pulse sensors this is the one inside the Timing Belt cover taking a trigger pulse off the Crank with a wire exiting the top of the Timing belt cover,part #30300-MG9-951 (original part) These sensors are all but non existent now anywhere in the world. There is a couple of ways to fix this, there is a company that rebuilds them.. or part # 30300-MN5-003 which is a pulse generator from a GL1500 which is more durable. Its a dual sensor so one can be a spare on the shelf, however it takes some modification to install because the mounting tabs are a bit different.I have one here which I'm going to install according to previous info given here. LTD & SEI owners beware its not a matter of "IF" this sensor goes its "WHEN" because it "WILL" fail eventually, my 85 LTD has 95k miles,its down until this is fixed,my sons LTD went around the same mileage a few years ago.
