87 accord no spark
Hello!
Trying to help fix my friend 87 accord. No spark.. Coil has power on the right side connector..Fuel pump comes on then shuts off when the key is turned on. I'm not seeing a check engine light when the key is turned on, just an oil light..No relay clicking under the dash. Checked for power at the ecu fuse and it has power. The fuse is good. When I plug and unplug #10 fuse ecu nothing happens.. I am trying to find the main relay and can't seem to find it.. The rpm tach does not move while cranking.. Any help would be cool.. Thanks...:cool: |
well if you have +12 on the positive side of the coil then you are not getting a negative pulse from the pickup.
|
I want to check the main relay, but still cannot find it.. Don't think the ecu is getting power. No check engine light comes on and can't here the main relay click.. .
|
Ok.. The main relay is working I think.. I can here it click when the key is turned on. Fuel pump comes on.. No check engine light. Gonna try checking the ecu now..
|
Can't find the main relay.. 87 accord..:confused:
|
Its not there???
86, 87, 88 and 89 Honda Accord and some Acura Integra relay location removal procedure: http://techautorepairs.com/relaylocationgif.gif The main relay is located just right above the hood release, inside the dash panel bolted to the left kick panel with a bolt that will fit a 10 mm socket. It has seven wires from the connector. Older Acura Legends is located behind the fuse panel near the firewall.

DX, LX or LX-i. You'll only find the main relay of it is injected (LX-i).

someone can correct me if I am wrong but if the OP has +12 on the coil then he does not have a main relay problem.
He has a ignition pick-up problem. The pick-up is what sends the negative pulse to the coil to make it spark. |
crispin - yes chasing the relay is not where the OP needs to be.
However the coil needs to be tested-both sides-and then the ICM/igniter before getting to the pickup. My post about the model (DX, LX or LXi) and the realy was more to get a tad bit more information from the OP. There are minor differences that would be nice to know. |

He has a ignition pick-up problem. The pick-up is what sends the negative pulse to the coil to make it spark. Having been on this website for a long time I can tell you that the O.P. will continue until he changes the main relay and only then will he believe it isn't the problem. A test light flashing on one side of the coil will tell the tale. "You can lead a horse to water......." |
