: distributor question

where is the top dead center on a 4.5 distributor. i got to wires figured out but i think i jumped a few teeth in one detection or another so im going to put it at TDC and go from there. i have a FSM but all it say is position the rotor between the #1 &#8. if this don't work it going to the mechanic to figure out whats wrong.

TDC refers to the #1 cylinder being at the top of the compression stroke

Not sure I understand exactly what you're asking

like you looking down at the top of the distributor with out the cap on where dose the rotor need to point for TDC on the distributor.

On mine, the square block for the coil wires on the side of the distributor cap points between the throttle body and the EGR

im talking about in the procedure to reset TDC if its lost . in the FSM its page 6d4-5 section D of the procedure.

With the harmonic balancer at the TDC mark the rotor should point to #1 in the distributor cap. It will turn a bit when you install the distributor so you have to allow for that so its pointing to #1 when seated.

Here's what I would do...
1. Remove #1 spark plug
2. Place your finger over #1 spark plug hole and turn crankshaft in the correct rotation slowly until compression is felt. (this will indicate if you are on the compression stroke for #1)
3. Align timing mark on pulley to ")" on engine timing indicator.
4. Turn rotor to point between #1 and #8 location on you distributor cap.
5. If you can't get the rotor to align between #1 and #8 and drop in, pull the distributor out and turn the oil pump shaft about 10-15 degrees. Distributor should drop in and rotor should point close to #1.

tried starting the car today but no luck. I decided to follow the service manual and removedthe distributor, routed the spark plug wires according to service manual.Inserted finger in cylinder one, slowly turned over motor. Felt compression stroke.It says then to align timing mark on pulley to 0.I am not sure if they mean remove pulley then align or try aligning while cranking motor.That can't been done since when I find top dead center the 0 timing mark is way off. I tried installing the distributor anyway when I felt compression stroke. I installed distributor like Service manual states and put rotor between 1&8 cylinder on the cap. I tried starting but it just back fired.I tried rotating distributor but no luck.Any help would be appreciated.
