i got a 92 vx hatch.i put a built dohc d16zc in it.my car has the 4 plug engine harness and i finally found the harness i need.once i wired up the motor the fuel pump doesnt turn on when i turn the key.when i hard wire it to the battery it turns on but i dont wanna have a fuel pump switch wired up in my car.i think it might be the main relay but does anyone have any ideas.i think i might have a short somewhere.please help

 

hmmm interesting...

 

Is the G101 ground on the thermostat housing clean and tight?

Is either hood fuse 31 or dash fuse 24 blown? See FAQs sticky for fuse box diagrams.

 

all my grounds are good and it doesnt blow any fuses.i made sure all my grounds where good when i dropped the motor in

 

Check those two fuses with a test light or multimeter as described at the Fuse link in my signature.

Also resolder the main relay.

 

what do you mean by resoldier the main relay?

thanks.ill try this tomorrow and if it doesnt work then ill repost

 

Be ready with a multimeter if the suggestions above don't happen to pan out.

 

i have a coupe laying around so im ready

 

couple*

 

i checked my main relay today.no broken soldiering joints or anything.i checked all the fuel pump wires and nothing is cut or shorted out.there is no blown fuses anywhere either.i turn the key once and the relay clicks.i turn it to the on position and the check engine light comes on and the relay doesnt click.doesnt that mean the relay is bad since they work on the 3 click system?

 

Did you test the two fuses as I mentioned?

I am being persistent here because members regularly say their fuses are good but were not because they did not test them.

 

ya everything checked out fine

 

Unplug the main relay and use a jumper wire to short terminal 1 (Yel/Wht wire) to terminal 7 (Yel/Grn wire) in the connector. Does the fuel pump run?

Do the same test but turn the key to ON(II) and then jump terminal 5 (Blk/Yel wire) to terminal 7. Does the fuel pump run?

 

isnt terminal 5 for on(1)?wouldnt i turn the key to on(1) and then jumper terminal 5 to terminal 7?

 

nevermind.i understand what your saying now

 

when i jumped terminal 1 to terminal 7 the pump didnt turn on but when i jumped terminal 5 to terminal 7 and turned the key the pump turned on.i tried to use a differnt relay but it didnt work.i guess that one was bad to

 

Sounds like 15A hood fuse 31 is blown. Did you test it?

 

no.i will test it tomorrow

 

ok hood fuse 24 was my problem.i got fuel.but now i dont think i have spark.any ideas?

 

1) Learn how to test fuses rather than just say they are fine.

2) The two quotes above are inconsistent. You said terminal 1 that gets power via hood fuse 31 did not make the fuel pump prime when jumped to terminal 7. This points to a blown hood fuse 31. However, you found "hood" fuse 24 blown. Hood fuse 24 doesn't exist but dash fuse 24 does. It's difficult to help you if you don't provide accurate information.

3) Test for spark. Don't guess.

 

i have spark now. but now it still doesnt start. it kickes over or a slit second then keep cranking. im gonna check timing in the morning. idk what else iy could be

 

What did you do to get spark?

Does the fuel pump prime now?

What color is spark?

 

ok.i got the fuel issue straightened out.i almost had my motor started.it turned over for a couple seconds then died.now i have no spark again.all fuses are good and all grounds are good.should i replace the ignitor,coil,and rotor?
