the engine turns over at like 150rpm. its got spark
it did fire up then die but now it just turns over and doesnt want to start at all
i changed points and condenser, im not sure how to adjust dwell? i heard i need to adjust every time points are changed but dont know how

You can do that, but what if that is not the problem?

Better to troubleshoot, pinpoint the problem, then fix what is needed. What are the current symptoms?
Quote:Is the engine turning? Got spark? Fires up but immediately dies?

well the car still doesnt work, it doesnt want to start again
i changed alot of things so im confused,well things my mechanic said would help.

where can i get my distributor converted to electronic my boss was telling me they just gut the old distributor and make it electronic ignition?

Let us know how you go.

If the carb you replaced was working fine before the spark issues started, use it to get timing right, then throw ya new carb on.

The new one may be well out of tune, which would make timing difficult.

it seems to be running alright now, also changed the rotor botton and cap, new carburettor is on so timing is next
it backfired today in my workshop sounded like a bomb went off
also checked the sparkplugs they looked burnt out like the car was running to rich

Hey patdaty, when Eva u do points and condenser u need to reset ur timing, that will be why it was backfiring ect... I found that out day b4 yesterday the hard way :)

well i just changed points and condenser and it started running but sounds very out of tune even backfired acouple times
going to adjust dwell, gap and timing tomorow see how it goes hopefully she goes alright
plus add on the new carburettor and fuel pump i recently purchased.

Try replacing your condensor(capacitor) (the small cylinder in or attached to your distributor) no need to replace the points at the same time at this point.

I have had lots of issues with condensors, they seem to 'dry out' over time and new ones are made in china in small factories that are not good quality, i went through 4 of them within 2000 miles before eventually installing a points replacement kit. The tech wiki says this is the best mod you can do to your Datsun, and i have to agree...

i tested my first spark lead while turning the starter over and the spark was very yellow and faint

What makes you think it is an electrical problem?

Sounds electrical to me

run a wire straight from the + on the battery to the + on the coil see if it starts, if it does you now know where to start looking...If it does start you will need to remove the wire off the + side of the battery to stop...all this does is bypass the loom for faults if it doesnt then the coil could be at fault.
