Default 93 eg that wont start - fuel pump doesn't prime

Sup Guys,

I'm in need of some desperate help. I start work next Monday so I need my car to run, any help is appreciated guys. The car has NOT been turned on for about 3 weeks.

Here at the specs:
93 EG DX, with a D16y8 Swap and a EX tranny

Here's what we have checked/know so far...

No CEL codes.
Battery reads: 11.75
Starter is NEW.
Has gas.
Checked distributor plug connections (1 was dirty, cleaned it and still nothing)
I thought it was the main relay, so I swaped it with my friends main relay and my car DIDNT start and his did, even with my main relay. (So im assuming thats not the problem)

I have no rear seats, so when I turn the key to the II position, I had my buddy put his ear on top of the fuel pump and we dont hear anything, I mean nothing.

So I took off the plate, and checked the wires for current. There's two sets of wires leading to two different places. One set leads to the fuel pump and the other to something else (not sure). Well, the one that leads to the fuel pump, doesnt get anything to it. No current what so ever. Yet, the other set of wires gets current. And this is where Im at, at the moment.

I have my laptop next to me in the car and I will be refreshing it often, if anyone can help me out that would be sweet. Thanks.

Check whether 15A hood fuse 31 or 15A dash fuse 24 is blown. The FAQs sticky has printable fuse box diagrams if you don't know where these fuses are.

Also make sure the G101 ground wire on the thermostat housing is clean and tight.

Has this car and swap ever run?

Checked out the FAQ diagrams like you said. Theres no pic for the underhood fuses for my year. It says "coming soon". checked all the fuses under the hood, they all checked good. Checked out fuse 15A in #24 position under the dash and its good.

This swap and car has been running for 5 years now....one big thing I kinda noticed that might be related to this is that for the past 3 months, the car would'nt start here and there. For example, in the morning the car would start perfectly fine, I'd let it warm up, go to the gas station to put gas, once I put gas I tried to turn it on and it wouldnt. I tried to crank and nothing, 5 minutes would pass of me sitting there cranking, and finally it would turn on fine. The car would work fine for about 2 weeks, then it happened again, it wouldnt start. Lately, its been happening more frequently until finally today, it didnt crank at all. Hope this helps.

G101 ground wire is nice and tight. Clean too.

You did not look carefully. What did you find?

Click the Fuses link in my signature. You need to test installed fuses 31 and 24 for voltage on both top test tabs.

If the starter won't crank, the battery may be dead (as suggested by 11.75V).

For the no-start problem, also resolder the main relay:

Fuse 24 checked out fine.

not trying to be a jerk or nothing but I dont see a fuse #31 neither on the diagram or under the dash. I saw in the diagram that a EK has a #31 fuse but not the EG. Am I blind or a common misunderstanding?

No problem Ron, checked it and it came out good.
Going to swap out batteries with my other ride and give that a shot.

I checked the wires leading to the fuel pump in volts. And no I didnt get anything to it. Like I previously mentioned earlier as well, is that when I tried cranking I didnt hear the fuel pump prime and when I checked the wires I didnt get anything either.

ok, here is exactly what it does.

I put the light meter on the main relay yellow/green wire, turn the car onto the II position and the light turns on for 2 seconds, then turns off.

I did the same in the end of the wires, close to the fuel pump and it gets NOTHING.

So what I did was follow the yellow/green wire from the fuel pump all the way to the side of the door, under the rug kinda. Checked it there as well, and nothing. So, it came to mind that the voltage might not be going down the wire like it should. So, I connected a wire from the yellow/green relay wire onto the wire under the rug and BAM, fuel pump primes. lol, wtf?

fuse 18 is good.

Interesting how the fuel pump primes now and before it wouldnt. But if I take off that piece of wire that I connected to the wire, it wont prime.

Both fuses checked out good.

Tested the blue/white wire on the main relay and got nothing. With the car off and in II position.

Were putting the fuel pump back in at the moment. I want to see if the car is going to start now since the fuel pump actually primes. I would love to know what exactly the problem is but I'm going to give this "mickey mouse" a quick try.
