ECU is OBD1 Eg Honda Civic with P06 harness with add vtec wires/ same as P28, with SI head and distributor same.

1.What should I check for when I know my ECU and distributor is good?

2.What are these wires from the ECU to the distributor?
a. Pin B6, Color Orange.
b. Pin B7, Color Orange with Blue strips.
c. Pin B8, Color Blue with Green strips then changes to -> Light Blue (on 94,95) or stays Blue with Green strips (on 92,93).
d. Pin B14, Color White.
e. Pin B15, Color White with Blue strips.
f. Pin A11 and A24, Color Red with Green Strips then changes to -> Yellow with Green strips.
g. Pin B6, Color Blue with Yellow Strips then changes to Blue with Yellow strips (92,93,94) or Light Blue with Yellow strips (95).
h. The black wire with yellow stripes is the power wire, im getting 12v from it when the key is on.
i. Lightish Blue wire on the same plug as the Black and Yellow (the bigger of the two plugs into the distributor).

3. I'm sure all these wires are important for the distributor to work. Where do i start checking? Which one sends a signal to the ICM (Ignition Control Module)? Other one to check and what voltage should i be seeing from these wires?

I was driving and my car just died and I pushed the car home. Ever since then, I do not have spark. ECU is good and distributor is good. I am getting fuel. Any help is appreciated.

Any input?

Seems like many of you guys have a lot more to say about the less technical ish.

 

From page 3 to page 1.

Does anyone know what the fuse for "backup" under the hood is for?

Backup for radio and clock, but will it prevent me from getting a spark? I bought a new fuse soon to replace

to the top. Any ideas?

 

the back up fuse under hood is for resetting ecu, radio.
check coils resistances, plug wires resistances. check power to the ignitor, coils.

 

main relay ? does it have fuel ? a guy at work had a car no spark no fuel but i can't remember what it was dang it i 'm getting old

 

One of the sensors may have gone bad.

 

didnt check for fuel yet, definately a good idea. Will check tomorow. Main relay seems good, no clicking.

I will check main relay and fuel tomorrow.

Dizzy is good for a fact. Power to ignitor and coil, both there.
Plug wires are good. Checked resistance already.

check that main relay.

 

Also check the altenator connections, could be a bad ground

Which connections? theres only one plug and a ground connection. Checked.
Grounds are good.

 

Today, me and brian tried to figure out this werid problem with no spark.

We now know that its not the dizzy, ecu, and any loose wiring from the dizzy harness.

We checked voltage from the dizzy harnesses (theres 2 on obd1 dizzys). There was power from the power harness, but when we were checking if there was any power or readings from the harness with 7 wires, a few showed no voltage on his harness, that showed voltage on my harness.

correction: I figured after xtremeazian left, i forgot to turn my car to the on position before checking readings. I had perfect readings after i put the car in the on position, so all my wiring seem fine.

 

Swap relays with ur friend there...

 

Will do tomorrow, its too late now, however, the main relay stories i hear about are mainly concern with no spark AND no fuel. But i hear my fuel pump priming?

eh..? I am getting fuel, and I can only think of one way a car can die. Maybe I'm stupid but how does any other car die besides for resulting in 0 RPM?

I never got my Car fixed yet, but my problem needs to do with ignition so I don't really know if my problem would be the same as yours but sure I will let you know when I figure out whats wrong with it.

Died while driving could be timing belt broke or slipped?

No. Timing belt is fine.
