Hey there I started the car a week ago, started no prob, then died.I've replaced coil dizzy and cap new rotor, new plugs replaced leads but still no spark from dizzy to block. When trying to start, it turns over, looses power and wont fire
The problem wont be your timing belt. you need to take out a spark plug plug it into your HT lead and check for a strong spark or even if there is a spark. check your contact breakers on the distributor as well

Do you mean you get spark from coil high tension wire to dizzy cap? If so, the only thing left is the cap and rotor and wires and the engine must have a good ground.
no spark from coil directly?
is the cam turning, is the dizzy rotor spinning. ????
check all fuses first. Ig-coil, FI and dome.
then using diagnostic jumper wire or fuse, (as approp)
crank engine look for code 41 o 42.!!!
USA cars , answers only
our cars are all EFI that year.
no engine swaps to Suzuki G16A/B sidekick or tracker engines.!
1: engine cranks
2: no spark
3: The ECu makes spark
the CMP sensor in the DIzzy , (never fails if rotor turns, does rotor turn, if not cam belt igored and now snapped.)
the cam turns. the CMP fires. the ECU takes this CMP signal
and fires the ignitor next to coil and the coil charges, and release and BAM spark.
that is it.
the ECU will tell you when the CMP dies or the Ignitor fails
why not ask it.
1: key on
2: diagnostic jumper in place (flashes 12s for ok)
3: crank engine,for 5sec, not 1 ,not 2.
3: release key not off.
4: see code 41, or 42, BINGO !@!!!!
Yeah like the guy above said check your dizzys coil. I had the EXACT problem. Also pick up a circuit tester and hook it to the dizzys ignition and have a friend turn the engine over. If the light blinks then it's the coil for sure
If you replaced the injector after the plugsthey may be fuel fouled.Pull the plugs and clean them.(you can sandblast them,or use a method I used to use-shoot a little starting fluid on them and use a lighter to burn off the contamination of too much fuel).I can't believe GM kept using this stupid design so long-I remember nearly new Vortec V6s with this same problem in the '90s.
The Honda system uses a coil that mounts inside the dist, right ? If you can check voltage output at the coil tower with the cap off you can find out if the coil is firing. If it is, then yes the rotor could be the problem. The voltage has to go thru the cap to the center of the rotor then to each plug terminal. The spark can jump thru the rotor and ground thru the dist shaft.
May be a bad coil even though it is a new one. Did you replace the rotor when you did the dizzy ? Considering all the other new items you've installed, it is very likely the ICM (ignition control module) or the ICM cable/connector harness
remove the dizzy cap, crank motor over to find out the rotation of the rotor. Remove the no.1 spark plug and bring no.1 piston up to top dead centre on compression stroke, mark side of dizzy body where the end of the rotor points to, replace dizzy cap and see which lead it lines up with.
that will be your no.1 lead, find the firing order and put the leads back on the dizzy cap in the direction of the rotors rotation, run those leads to the corresponding plugs and it should start.
