Ok, so Ive been having problems with my car for s while now. Fresh Motor swap and the sob will not get any spark to the plugs.

First off its an HF with a b16a2 all obd0
Heres whats been done:
New coil,igniter,plugs,wires,main relay,cap,rotor
New Si Engine harness from honda
Swapped a friends ecu, distributor,fuse box,wires.
Checked all grounds and measured ohm resistance for good ground

Still no spark.
what now.

Im seriously out of ideas and need this fixed like yesturday.
Any help would be appreciated and If you Can come out and get this car started this weekend you can have a handfull of cash.

 

have you tried systematically checking for power through the whole system?

-as in, start from the ECU wires that go to the dizzy, check for power, then follow the wires, check em at the dizzy, etc. etc.

checked all your grounds?

also, does it crank over fine and just not spark, or are there any other probs/CELs?

**EDIT** sorry, missed the part about the grounds. just saw it.

 

cranks, spits fuel, no cels, check power plug at dist and was at 12.55 volts

 

check your spark plug wires and they are in correct order? had this happen a while bck on buddies h22

 

are you kidding me, I have my wires right, and even if they were completely ass backwords...they would still throw spark.

 

yea, they certainly would





i dont want to insult your intelligence, but right plug heat range and gap? god knows ive done it myself...

and you said in the post that you "tried a friends ECU/dizzy/wires", you still didnt get spark? even with a good dizzy and ECU?

and im assuming you checked the clearance between rotor terminal and cap terminals?

 

gaps are good. it seems to me like a ground issue but I checked the resistance between body grounds . does anyone have a helms or a diagram for the wires going into the distributor? I want to check to see if I'm getting correct voltage through all the wires.

 

you getting power at the coil?

is your harness grounded at the thermostat housing?

 

yea, but my engine has two grounding locations, one on the thermoside,and one right next to the that one on the egine where the thermo bolts. maybe I should loop the ground to both points ?
