Engine turns but sounds like there is no power mining no compression all the point ie marks in the pullies where in the correct position I advanced the firing order with no luck, again all three marks where sat 12 o clock position and tdc up

Assuming points, coil, distributor.

Remove spark plugs. Turn crank by hand with long socket wrench at balancer until near TDC compression stroke of cylinder 1. Now turn crank forward/backward unil timing mark aligns to the degree mark you want (advance or retard).

Connect a volt meter to the points side of the ignition coil and ground (engine block). Turn ignition switch to RUN position, do not start. If meter is near zero volts then points are closed. Likewise if meter is near battery voltage then points are open.

Slowly rotate distributor a few degrees either direction until points just open. Verify the distributor rotor is aligned with the cylinder 1 position of the distributor cap (plug wire 1). If the cap and rotor are not in proper alignment, make necessary corrections.

is this a points distributor
place the timing mark at the desired position before tdc compression stroke ( normally around 10 degrees )
se the points to correct gap
turn on the ignition and move the distributor body against direction of rotation until the points just open ( noise or spark across points
tighten the distributor at this position
replace cap and it will start
alight when used will show the timing to be almost at that setting
if pointless distributor
set the timing mark as described and the set the apex of the exciter at the mark on the small pickup in the distributor
That again will be the timing mark setting
if it is an efi engine
the ecm unit will determine the timing of the engine from the crank position sensor

if you mean the plug wires do the following. remove number one spark plug,turn engine over till you feel compression coming out of cylinder, find tdc mark on timing cover, turn motor over till mark on crankshaft pully lines up with timing cover mark, remove distributor cap, rotor now points to number one plug wire, check rotor rotation, firing order 4 cylinder motor 1324 6 cyl 153624.

Remove No 1 spark plug turn engine till compression felt. align mark on crankshaft pully with mark on timing cover , distributer roter now points to No 1 on cap. Firing order 6 cyl 153624 4 Cyl 1342. check which roter turns and connect cables as above

if distributer has ever been out most likely it didnt get put back in same position. pull the #1 plug have some one cover plug hole with finger, by hand or with a socket on crank pully turn crank to your right( when facing engine) until you bring timing mark up to tdcas mark gets close air should blow by finger that way you know your on compression stroke pull distrib cap and see where rotor is pointing thats your new number 1 wire the rest accordingly

Sounds like timing is out .Re set belt.Is it a 5sfe motor?

i dont have a more detailed picture of setting the timing marks for the belt so i hope this helps

its tricky enough if your not sure what your doing but ill run you through it. 1. remove top rocker cover and timing belt cover. 2 make up the position of the pully on the cam shaft at the top and the drive shaft at the bottom, this marks are you fail safe incase you cant time the engine. 3 remove the timing belt and pully tentioner, note if your going this far you are as well to replace the timing belt,tentioner and water pump. 4 On the cam shaft at the top if you force them to turn you will see a small indicator mark on the shaft this mark has to line up with the other indicator mark on the housing between the cam shaft and the cam shaft pully, once they line up your top end is timed, mark up the pully incase it moves. 5 on the drive shaft pully there is also markings that have to line up but you can also feel the position of the pully as you turn it, you will feel the piston been forced up and it is timed at top dead centre on cylinder one, which means the the piston has to be at the top just before the point of returning back down, using your feeling as a guide and the markings lined up you will have timing. also mark up this pully, your new marking should be very very close to the fail safe markings you put on at the start. when you have your marking replace the timing belt with the longest distance between pully contact going on first, try not disturb your timing or your hard work will have been for nothing, make sure the tentioner on the belt is tight but not to tight to the point where you ll stretch the belt or snap it, put everything back as you found it and crank the engine, job done, best of luck. hope this helps( rate me on my answer thanks )

hi from uk the cambelt timing marks at TDC are as follows--the crank gear mark is lined up with mark on front of engineblock at approx 10-30 am position the marks are clear as you look ? the cam coghas a dot/pop mark just below teeth this mark is at top ie 12-0'clock position now on cam cog you will also see s hole drilledon the cog web also at 12-o/clock if you look thro this hole (use a mirror ?) the hole lines up to a grooved vertical line at the rear which is on front of engine at this point you fit belt fron crank pully anti clockwise round cam cig then reset tensioner when marks are rechecked with belt fitted/tensioned ? turn engine manually two full rotations clockwise then recheck all mark line up again ? then re assemble ? c/shaft pully bolt tightens to=170-180 Nm hope you notice that the new belt is marked as to its rotation with arrows hope this helps ?best wishes from uk

Ibring piston to compression stroke. Apiece of tissue in the plug hole will blow out and then turn crank by hand until the piston is at the top. There should be timing mstks on the crankshaft pully.no timing marks? Then ease the crank around untill the piston starts to go done you can feel the piston with a straw. Note, the crank pully keyway more than like be at the 12 oclock position. good luck
