Follow this easy instruccions if you want to reinstall a distributor on a vehicle where the crankshaft was moved from the position it was when the distributor was removed.
Remove #1 spark plug
Place your finger over the spark plug hole while turning the engine with a wrench on the pulley bolt at the front of the engine.
When you feel compression continue turning the crankshaft slowly until the timing mark on the vibration damper is aligned with the "0" on the engine timing indicator.
Position the disttributor rotor between the number 1 & 8 (for 8 Cil.) 1 & 6 (for 6 Cil.) or 1 & 4 (for 4 Cil.) spark plug terminals on the cap.
Lower Dist. into engine. To set the gear on the bottom of the distribuitor, you may need to turn the rotor a little bit. If the distributor does not drop down flush against the block is because the distributor shaft has not mated the oil pump shaft, if this happens, place a large socket w/braker bar on the crankshaft bolt and turn the engine over in the normal direction of rotation until the two shafts engage properly and the distributor sits flush against block.
With the base of the distributor properly seated, turn dist. housing to align the marks you made in dist. base and engine block. (you did make this marks before removal right? : )
Place the hold down clamp and install the hold down bolt not too tight. Install dist. cap an reconect electrical plugs, spark plug wires, etc.
Check ignition timing and when set, tighten dist. hold down bolt.
With ignition OFF, remove the dist cap , do not remove HT leads from cap or plugs just move to one side ,turn the crankshaft with a spanner on the crank pulley drive nut until the rotor arm is pointing directly towards the front of the vehicle, mark the position of the rotor on the distributor body with a dab of paint and also mark the position of the body on the engine block infront of the distrbutor,remove the distributor , i believe it's just 2 screws that clamp it in place ,transfer the mark from old dist to the new dist and aling the rotor to this mark, then fit the new dist to engine and aligne the marks from the new dist to the mark on the engine block and tighten down , refit the dist cap , to get an exact distributor timing you should now use a timing light to check the timing marks line up , if they are slightly out just very slowly turn the distributer until the marks are aligned , hope this is of help
The 1990 had points still or did it have the electronic ignition? There are only a few things to change on the electronic ignition. First the plugs have to go, get some Titanium tips in there, good for 100,000 miles, then some plug wires if you think it needs them, air filter, check all the fluids, coolant, brakes, power steering, battery water, tranny, if it has a dist with points, get a new cap and rotor and a set of points, gap them exactly to spec, or it won't run. run a can of stp through the fuel tank and clean out the injectors, or carb, the oil change doesn't come with a tune up, it comes automatically with the 3 to 5 thousand mile interval.
If the battery is boiling while engine is running,the alternator is over charging,the battery maybe bad now,this can cause the plates in the battery to fry,have the battery load tested on an electronic tester,not an analog ,cause it can blow up,make sure the battery cables are on the battery correctly,if this was any help,at all,please rate,and thank you,
You have already replace dist,I had one in my shop that did the same thing I finally got a hold of a dealer and said the dist shaft had to be demagnitized I pull dist and shaft sent it to the dealer and never had anymore problems,I hope this helps you
take out number 1 spark plug and put your finger as to block the hole ,have a friend bump the starter till you feel air rush out real fast / called the compression stroke when it does stop and look down the top center for timing marks on the pulley and line them up on the timing cover then place the distributor in place as so the rotor is pointing at the #1 piston location, basically the dr. front corner and start there, timing order is 1..8..4..3..6..5..7..2.. now if you get all these in right 1..3..5..7 are on the drivers side front to back and 2..4..6..8 on the passengers bank front to back and the distributor turns clockwise .good luck hope this helps you.
