My 1986 honda civic 1.5 jumped timing. I need to now what parts I might need to fix it and where the timing marks are. I think i need a new tensioner and replace any gaskets that i encounter. please help

Jumped timing, replace belt.

the red mark is where the timing is supposed to be after u have bypassed the electronic advance.the first white line on the left is tdc.

Before removing the timing belt bring the engine to the timing marks and if your engine is working ok,then use the marks by using some reflecting paint . Loose the timing tensioner and remove the belt. fitting the new belt and tensioner be careful on the installation the marks to be on the marks and fit it. release the tensioner and tight it. Turn the engine by hand twice and re check the timing marks.fit the covers crank pulley and mounting and start the engine.

On the Cam gear are three marks. On the face of the gear it should say "up", then you have three marks one at 3 o'clock one at 7 o'clock one at 9 o'clock. the one at 7 should align up with a mark on the block. Some have a raised semicircle and you line up the 7 o'clock mark on the cam with the far left hand end of that semicircle. Now on the crack end you have a mark at the 2 o'clock position and it lines up with a mark on the block. Do not turn the crank or the cam independent of one another, as the valves can be bent. Remove the spark plugs to ease turning the engine when needed. The engine will turn counterclockwise. Remove all necessary left hand front wheel, inner fender splash guard, covers, top engine mount. turn the engine until number 1 cyl. is at TDC compression stroke, and all timing marks align as noted. Remove the lower crankshaft bolt and pulley, and lower belt cover. Loosen tensioner bolt and push it out of your way and remove the belt. Put on the new timing belt in this order, crank sprocket, cam sprocket, water pump sprocket, tensioner. Belt must be tight on no tensioner side. Push the tensioner against the belt. Turn the engine 4 turns counterclockwise, until the timing marks realign, loosen the tensioner and turn the engine again 3 teeth, torque the tensioner to 30 flbs. reinstall all the mounts and covers. all should be good.

Clockwise 1--3--4--2 On Distributor Cap

#2) Your Ingnition Timing , Make sure engines temp is at normal operating temperture, #3) Pull out Engine Service Connector, which is located behind RIGHT SIDE KICK PANEL .

#4) Now take a Jumper wire and Jump the BROWN WIRE with the GREEN AND WHITE Wire Terminals on the Connector.CAUTION: DO NOT JUMP THE 3PIN Data Link on Vehicles 1993 and Up.

#5) Now Connect Timing Light There is a Mark on your Bottom (Crankshaft Pully) Its Red in Color,NOTE: you might have to clean this up before even beginning anything.!

#6) But Look Down to lower Crankshaft Pulley the Timing Light should be Lined up to the RED Mark.Your Timimg Sets at 16 Degrees Before Top Dead Center and Idle should be 670 RPM

The cap should be marked for number 1. The distributor turns clockwise. The firing order is 1-3-4-2.

The only other thing could the the timing belt tensioner if there is any doubt. Here's the timing marks.
