im going to try out a new main relay not sure if that's going to do anything. I've done 2 differant dizzys and 2 ecus. Any ideas?

wu tang

also..are 88-2000 main relays the same?

Former User

The main relay controls fuel not spark. Check the coil and igniter in the distributor. Also make sure there aren't any blown fuses and that the distributor connector is getting battery voltage.

wu tang

is this the black/yellow wire? if so it is getting power. Someone told me the main relay does control some spark to. but i was alittle confused on that part. also the dizzy i have works i know that for a fact. i took it out of a friends running car

Former User

The main relay controls the fuel pump and fuel injectors. Is the fuel pump priming?

Check the critical ground wire on the thermostat housing -- loose, disconnected, corroded?

wu tang

fuel is priming and grounds are good to go. Im wondering if im missing something down under the dash? but i dunno im quite confused though

Former User

Is it an 88 Civic? Is the CEL ON?

wu tang

96 civic hb

If you have power to the distributor, no CEL codes (e.g., distributor sensors), and grounds are good, then focus on the coil and igniter and their wires and connectors.

Have you also inspected the plugs, wires, cap and rotor?

Check whether fuse 47 (hood) or fuse 31 (dash) is blown.

Are you able to retrieve any CEL codes?

Former User

Results from tests in the diagram should be informative, particularly those with the YEL/GRN wire.

wu tang

perfect thank you. Also i'm in idot the fuel pump is not turning on. lol so..where is that dang main relay at?

Pull out the glove box and it is on the right.

have fun its all the way under your dash. i might be wrong but it should be on the left hand side.

wu tang

good thing i like to have fun then. Are 88-00 main relays the same?

Former User

Now that you know that you also don't have fuel, you may want to check the wire between the MAP sensor and ECU at some point.

jsut went tot he car again. Now i have fuel lol. my codes are 20 and 14. I'm not worryed about the 14. car still would not start. no spark still

Former User

Try the electrical troubleshooting of the distributor shown in the diagram of my earlier post.

wu tang

I will go back to the car tomorrow. Thank you for your help and i shall let you know the results tomorrow.

wu tang

sunday night....new status. The only code im throwing now is a 41. still no spark

Former User

Yeah, a problem with the primary O2 sensor/heater (code 41) isn't going to lead to a no-spark situation.

wu tang

yup. but everything is good, fuze/grounds/ecu/dizzy. its just weird

worlds-slowest-EG

use a little di-electric grease on the ignitor on the front and back it solved my problem i had no spark and no cel's tried 4 ignitors and 3 coils but all it took was a little lube

wu tang

shes alive!!! thank you
