i have done all that link said 4 time and still will crank but runs real rough i mean like it about to go dead any help

 

I always take the spark plug out in cylinder number 1 and push a ball of paper towel big enough to fit kinda snug just in the spark plug hole and slowly turn the engine over by hand, and when the number 1 cylinder reaches top dead center compression stroke it will literally pop and shoot the paper towel ball right out!! then you know you are really close to top dead center and you can continue through the correct procedure using the line up marks on the dampener and on the distributor, and also MAKE SURE YOU DON'T HAVE WIRES FOR CYLINDER NUMBER 1 AND CYLINDER NUMBER 3 BACKWARDS AT THE DISTIBUTOR, causing the rough running problem also cause alot of people make this mistake.

 

ok thanks i'll give it a try and i will look at the wires to make sure thank for the help

 

Put it at top dead center and drop the distributor in so it lines up with the number six on the distributor housing (It is a little stamped mark that is on the housing). I dont mean any disrespect but where is number 1 cylinder to you,it should be LH front while sitting in vehicle

 

i know where the #1 is and i tought i had it at TDC and had the distributor drop in on the number 6 and when i crank it up it back fires alot so i know it out of time can u hook it to a scan tool to see if ur at TDC i got a friend that has one i work on a lot of car&truck and had to put alot back in time but this one is being a pain in the @ZZ thanks for the help

 

thanks guy for all the help BUT i still can not get this thing in time i keep reading about a advance timimg wire that need to be unpluged where is it and any help


this is what i have done i removed the #1 plug trun the moter by hand my friend put his finger over pluge hole till air came out we turned it till the marks on top and side where lined up put disturber was back in flush on the 6 mark i mean dead on it put all back together and still will not run if it does it back firein grun rough and that it do it all over again i ready to burn the dang thing i never had the much trouble out of a car

 

The timing wire is on the older engines only and has nothing to do with the engines equiped with the EDI distributor. On these ignition systems, you must find TDC #1, then align both of the timing marks on the balancer as shown in the DIY article linked to above.

The crank should be only slightly advanced beyond TDC #1. If you are rotating the crank over 15 degrees, that is too far and the balancer may have somehow slipped. Another member recently ran into this. He replaced the balancer and the motor timed perfectly the first time after.

 

i hauled it to the shop today so maybe i'll know some thing in the am i will let yall know what they say thanks again for the help
