I have a 94 s10 blazer 4.3 and I had to remove the distributor but never marked it so now the timing is messed up. The distributor dose not have a #6 alignment mark so I cant get it working right. How do I align the rotor and distributor?

what happened the last time it ran

did it run hot or ??

Check the oil - if none -- you could have turned a bearing. In that case, the next would be a compression test.

Best regards

The cap is marked. look at the top of the cap where the wires are attached. they are numbered.

If you removed the cap only, you couldn't have thrown off the timing. Did you make sure it wasn't reassembled half a turn off? Also when cleaning it, the cap must be completely dry inside. If you used a liquid to clean it, remove it and spray it out with WD-40.

If you have not removed the old one yet, make a mark on the fire wall or in-take, where the distributor rotor is pointing to, also mark where distributor housing is sitting at that way you will still be in ignition timing, remove bolt at base of distributor, remove holding bracket, slide distributor out, install new one to where all mark's you made and your done, hope this was very helpful.

991 Chevy S10 firing order
The firing order for a Chevy s10 depends on which engine you have.
1.9L engine the firing order is: 1-3-4-2 . Distributor rotates counterclockwise.
2.0L engine the firing order is: 1-3-4-2 . Distributor rotates clockwise.
2.5L engine the firing order is: 1-3-4-2 . Distributor rotates clockwise.
2.8L engine the firing order is: 1-2-3-4-5-6 . Distributor rotates clockwise.
4.3L engine the firing order is: 1-6-5-4-3-2 . Distributor rotates clockwise.

The timing is not adjustable. There are two lines on the harmonic balancer, the first line should line up with the mark on the timing cover, towards the bottom, on the driver side of the engine, the second line should line up with an arrow on the timing cover above the first mark. You'll need to have the rotor in the distributor lined up with the "6" on the distributor housing. You may need a long screw driver to turn the oil pump shaft to get the distributor lined up right.
