1991 240sx: question about timing and distributor cap and rotor

[vancouverbc]

1. Timing question: I had my distributor out today as I was removing timing chain guides. I have the crankshaft postioned so timing pin points at the tdc mark on pulley. My distributor rotor is pointed at the no. 4 cylinder. I assume this is ok? Just 360 degrees off?

2. The picture below shows my dist. cap. It seems to be missing the center piece? The would start but ran extremely weak and smooth. I put another dist. cap on but car would not start at all. I assume my battery is weak.



3. this is my rotor. never seen one with a hole in it but it has worked.

well the rotor should be pionting to cyc 1 when cyc 1 on tdc, before u put the dizzy in. turn the rotor to piont to cyc 4 of the dizzy and when u install the dizzy the rotor should end up pionting to cyc 1.

lmk how u make out im doin mine this weekend and will know for sure

look up tutorial in my signature. there is article on distributor timing. im pretty sure the pin lines up with timing notch when dist rotor points at cyl 4 and cyl 1.

changed rotor, jump started and reset computer but car does not start. only turns over.

The center terminal on my old dist. cap seems to have fallen off while I had it off. I think that is why my car ran so weakly when I first tried to start car.

I tried a new dist. cap but car does not start (only cranks). I'm thinking I ruined the distributor somehow.



Not sure why there is a hole in my dist. rotor. I know that was there when I took distributor out of car so my car runs with that hole existing in rotor.( i have tried a new rotor to no avail)

only the first 15 seconds is relevant. two sparks. is this a good quality spark? choose high quality under the view count.

Try using another distributor, I had the same issue when I did my chain guides.

Must have been flooded because it now works perfectly where it didnt work at all before. exact same setting with nothing touched. worked fine on at least half the tooth. i guess just running it with bad timing can flood it.

if i had just pulled dist. out and not moved anything i think i would be fine. all my marks were exactly the same the first time i tried with broken dist. cap. the dist. gear rotates coming out but rotates the same amount in opposite direction going in.
