I just swapped my 95 civc D16Z6 for a 97 civic D16Y8 becasue my engine went out. I swapped intake manifold, alternator, and distributor from my Z6 to the Y8 so that i could use the 95 ECU and wiring harness.

I am gettin spark but i dont think I am gettin fuel to my fuel rail. The car also makes a weird noise like something is tryin to pump, it sounds like a quiet wannabe air compressor, and my speedo jumps to 25mph as soon as the key is turned over. My car wont start, but it sounds like it wants to.

What is wrong? What should I do?

 

re-check fuel lines.....all harness...sound like u still might have an issue matching your head to ecu.

 

All grounds tight?

As long as he swapped over the manifold and dizzy (which requires some modification to bolt up) It should work just fine. Friend of mine did a y7 swap in simliar fashion to his hatch.

X2 on checking the grounds and making sure they are secure.

That sound you hear is the fuel pump priming, but if its that unnaturally loud as you said, check to make sure all your fuel components are correctly installed. Youd be surprised what problems you can run into just by leaving out the washer for the line that goes to your fuel rail, double check everything to make sure its correct.

As for your speedo, may just be coincidence that you have some of wiring issue, it may or may not be in the wires, but possibly in the cluster itself. Sounds like a grounding issue tho.

 

Definitely double check the ground on the thermostat housing

 

Thanks for all of the tips ill give those all a looks at then let you all no how it goes.

And to whoever said "he", just so you know, im a girl.

 

i checked my car again and i found out that the noise is comeing from my main relay, im pretty sure. should i just replace it with a new 95 honda civic main relay?

Is a bad relay the reason why my car is not getting any fuel?

hehe oops, my apologies miss.

 

that could definately be the prob. swap it out any see. make sure the plug didnt get loose somehow. to be honest i had a prob simaliar to this before, and i just tap kinda hard on the relay, and it actually started to work fine.

 

If you are hearing the noise from the main relay, that means its working. I would check elsewhere...Unless the noise is really loud and abnormal. But the relay should make some kind of noise when the fuel pump is priming.

 

i know whatt it sounds like when you first turn the key and the pump is priming i hear that sound but thats not the weird one. the sound thats now coming from the main relay is very loud and doesnt sound good.

 

do you know if the main relay on a 95 and 97 are the same?

does the speedo go into the main relay?

 

i got my car to run, you guys were right it was the thermostat ground. but now my battery keeps dying and my instrument panel and radio will shut off. is my alternator battery maybe not tight enough?

Check all the fuses, however you should be throwing a CEL code if one is blown. But check all fuses anyways, exspecially # 15 in the underdash fuse box. This deals directly with the alternator circuit. Also, because you kept cranking the engine over and it wouldnt start, you may have damaged the battery and depleted the power that was initially stored in it. Try charging the battery with a battery charger and bringing its amperage back up to normal... if not I say just buying a new battery will fix the issue. I don't think its a bad alternator.

 

I agree just charge the battery

 

check the grounds and bleed the fuel filter...i had the same problem before.
