wow, im so stumped on this one im posting it on hondatech lol

car is a 92 DX automatic. started and ran fine before i started messing with it.

i replaced the radiator, thermostat, spark plugs, and adjusted the valve clearance. thats it. and now it cranks but wont start..

-it has spark in all 4 cylinders
-it has fuel in every cylinder (plugs are soaked), main relay and fuel pump works.
-cam timing is dead on, tdc mark on crank pulley lined up with mark on timing cover and marks on cam gear lined up with head and "UP" is up
-compression is perfect in every cylinder
-replaced dizzy with known good one
-no cel's
-replaced ecu with known good one
-checked ecu and engine grounds, all are cleaned and good
-checked all fuses under hood and under dash

so after all this it still isnt starting. its obvious its sparking at the wrong time, but HOW? when i have done all the above and its all checked out fine..

this really sucks, i was suppose to be selling this car tommorow and just did a little fixing up on it and now this bullshit had to happen. i really dont know what it could be, id love to hear someone elses answer to this.

 

did you check that the plug wires are on the right firing order??

brand new ngk plugs and pregapped. and i rechecked gap aslo

and also forgot to mention the firing order is correct.

 

ive been working on it again all morning and still nothing. i dont think there is anything left that i ahvent tried. for the first time ever i really dont know what to do.

because ive been working on hondas for over 8 years now.

that and i didnt even touch the plug wires on the dizzy. like i said ran fine before this and now wont start. oem plug wires are even numbered and different lengths.

(distributor) 4 3 2 1 (timing belt)

dizzy (d15b7)

( 1 3 |
( 2 4 |

so now we can totally drop that out of the equation, whats next? i have never been this stumped working on a honda in my life.

 

it was the distibutor. dont know how because i didnt even touch it and it just went bad overnight. i put another z6 distributor on it and it fires up. no bolt holes lined up so i just vicegripped it on there.

that is really really strange because the b7 dizzy was putting out spark so that means one of the 3 sensors inside wasnt working right but i did the ohm test on all of them and they came out good and also tore apart dizzy and checked everything over and its fine. but now i guess i just need a new dizzy unless i just put the z6 internals into the b7 dizzy housing.

 

the coil probably went out

it was sparking in every cylinder. just not at the right time. so now the coil wasnt the problem. i just stated above what the problem was.
