No ignition. Good battery and starter fine but not a thing from engine. Engine diagnostics wont interface with car-- 2 mechanics have tried and have given up!! I know there is a limit to time a mechanic can spend...
1994 NG 900.
no spark installed new cap, rotor, wires and plugs still nothing

How about the control side ? digital transmission range switch , starter relay ,ignition switch . Do you know what these thing's are ? Free wiring diagrams here http://www.bbbind.com/free_tsb.html
Enter vehicle info. year , make , model and engine size. Under system click on engine ,then under subsystem click on starting . Click the search button then the blue link. How to voltage drop test starter motor circuit
The way to start is to ck your battery for 12V & clean bat terminals. Ck the ignition fuse &locate & ck the starter relay for power & ground. Jump the relay between the 2 conn (pwr/grd) See if you start.. Key on If OK r/r relay, If it doesn't work, follow the RED wire to the starter & ck for 12V there. Also ck for a good ground conn at the starter (both with good readings & clean conn. If all is well there when someone else is turning the ignition key to start, then the starter is NG If readings at the starter NG, relocate the starter relay. Good luck, Frank M
What year,make model and engine size is this car, it sounds like a battery connection or bad starter, hold the key in the crank position and test for power at starter, you will be testing the small wire at starter. the big wire will have power at all times, the small wire should have power when the key is in the crank position,
If the battery terminals are clean and tight and battery tested good and there is power to small starter wire with the key in the crank position then starter is bad. try to tap on starter with key cranked and see if it spins, if it does then starter is bad. good day
TRY USING A 1/2 LARGE SOCKET AND 1/2 INCH RATCHET WRENCH TRY TURNING CRANKSHAFT PULLEY BOLT TO SEE IF ENGINE WILL TURN OVER IF SO ENGINE NOT SEIZED UP. IF ENGINE WONT TURN OVER MORE LIKELY ENGINE HAS SEIZED UP.IF ENGINE CAN BE TURNED USING A WRENCH CHECK BATTERY VOLTAGE SHOULD BE 12.6 VOLTS. IF BATTERY GOOD REPLACE OR CLEAN BATTERY CABLES AND BATTERY POST TERMINALS. IF BATTERY AND CABLES OKAY. REMOVE STARTER AND HAVE STARTER AND SOLENOID CHECK OUT AT A AUTO PARTS STORES.TURN OFF RADIO FIRST BEFORE REMOVING NEGATIVE BATTERY CABLE.IF STARTER AND BATTERY GOOD PROBLEM IN THE IGNITION SWITCH OR THEFT SECURITY MODE IS ON DISABLING STARTER AND FUEL PUMP.
There are 5 items in a starting system : Battery, cables,relay, ignition switch,starter.
Well you've replace The starter . lets make sure your battery is in good condition and is fully charged ( I recommend you have the battery load tested), If this checks out next are the cables off the battery and the starter terminals.( must be clean and tight) do a voltage drop test on them to see if there is a resistance problem). Use the shop manual and locate the starter relay make sure its free of corrosion and test it for continuity and resistance). Lastly ignition switch, this is a pain in the neck. Because this a delicate and hard to reach circuit have a repair shop do the testing on this .
Believe me its money well spent.
