Ok I have a 89 240sx fastback and a redtop s13 sr going in, its in everything electrical works, headlights turn signals vents everything. Except the engine, I turn the key and just get a click sound, the fuel pump isn't priming either. I get nothing except a click sound that comes from the drivers side fusebox. The battery is NOT dead. My thoughts are its my battery area wiring Ill get pics of the things to check, I did them exactly like the heavythrottle site said, I even rechecked them. But they are still the only thing I can think of that would do what its doing. If this makes no sense.

Heres some pics to help



These are 3 three I dont have connected that are on the side of the fusebox closest to the firewall.



The 2 I have connected on the side of the fuse box right beside the engine, and yes I have the other one on this side connected I know that one goes there for sure!



These are the wires on heavythrottle battery area diagram f8 plug seem right that one doesnt have tape on it cause I was testing something but it didnt work before that..



I dont know how useful this pic will be but thats both plugs wired up and sodered

take a look and see if you see anything wrong here.. or if you need a better explanation/different pic just ask. Im wondering here, I wanna have it ready to go to the bbq meet in vancouver this weekend.

If you're not getting fuel pressure then your fuel pump isn't turning on. Check the fuse/relay for it.

From what I can see your wiring seems correct.

If you want to see the originals they are the last 4 pics of this..

http://www.imagestation.com/album/?id=4290207791

they are much bigger/better quality to see it good. Also how many ground wires are there I have the neg battery cable grounded on that spot for it on the intake manifold and theres another smaller one thats black with a white stripe Im pretty sure I put that on another bolt on the intake manifold.

Green/yellow stripe you have connected on brown plug should be connected to green/yellow stripe on gray plug...this doesn't matter since that's only for AC.

I can't really tell from your picture in your photo album, but is the black/pink stripe wire connected to the brown plug? If it is then it's fine...if not then that's probably where you messed up. Other than that everything checks out fine.

Maybe you just have a dead fuel pump or something. Hear starter click? Maybe your battery terminals aren't on tight so whenever you try to crank up the engine the terminals would just jump and not give any power. And listen to see if your starter is turning on or not.

check fuel pump fuse first, then check to make sure you have fuel hoses hooked up correctly, then make sure you have the clutch in and turn the key again...

would mixed up vacum lines do this??? Im getting really desperate here I still just get 1 click when I turn the key and the same 1 click when I turn the key off. All the fuses work like the 10 amp and 15 amp blues how can I tell on the big ones that are like 75 amp if they are blown?

Oh this is a 89 fastback that was auto that I changed to 5 speed if that helps any more bit

also even the horn works and thats run off the same fuse box as the fuel pump/ignition could it be that both my pump and starter and messed?

Ok I think someone that has done an auto to manual sr swap can help you on this further, unfortunately I can not help.

I thought fuel turns on when the ecu senses engine rotation through the crank sensor. So without the motor turning, it possibly isn't turning on. I don't know if this system works for older japanese cars, but newer automobiles do this. Is the starter seized up? Try giving the starter direct power and see if it turns the engine over.

i thought if you turned the power in a car on, then you could hear the fuel pump prime before you even started the motor, at least thats how its been in other cars for me

What ecu are you using? Timmybgood, you are correct. The fuel pump is supposed to come on to prime. I think wireing is crossed somewhere or you have blown a biggun. Look under the black box under the hood and check the big ones. You dont have to pull them out to look.

Yeah, that's correct..I wasn't thinking right. It's the injectors that wait for the crank sensor.

Hey Krazy,

Did you short out the thick Black w/ Yellow stripe and Black w/ White stripe on E12 in engine harness #2? These two wires need to be connected to each other to bypass the Park and Neutral switch that was in your auto transmission. I will be doing auto to manual conversion with SR swap too as soon as my engine is here. Hope it helps.

When I was in "mechanic school", we had a starter/electric tech as a guest from a/c delco describing in's and out's of an electrical system and starters. To put it short, relays, switches, bypasses etc are a pain if you dont know where they go. Also, a starter is supposed to spin with the gear shaft extending when power is put to it.

Ok I have not done the neutral thing! That has to be it, could you explain where these wires are? Thanks SOOO much I think that will do it.

Hi Krazy,

I have problem trying to find it myself. Well, maybe, I haven't really tried hard enough since I'm still waiting for the engine to come. Anyway, from FSM, that E12 is the top most connector behind the fuse box. When I tried to find it the other day, it seems like it has 3 wires instead of just 2. I didn't really pay attention to the wire colors, but it looks like 2 of them are black color (couldn't see the stripe since it was dark outside), but for sure the other wire is white. From the FSM, the E12 is supposed to be 2 wire connector, but I couldn't find 2-wire connector behind the fuse box. I suppose I could ohm it out to find if the two black wires are the ones to shorted. Well, maybe you could do it and tell us here in the forum if that 3 wire connector is indeed E12.

A note

Try and find a manual car when doing the swap. makes things easier.

It wasnt to bad converting actaully it was all easy and straight forward just that neutral thing. Oh and a 89 240sx driveshaft will fit the sr right?

Thats the standard one the top one.. but its like missing something where it plugs into the transmission does something bolt onto the end and go into the transmission? And whats it called so I can pick it up tommorow.

Lol, thanks Mojoman. I'm still learning though. I will be doing what krazy did in a few days. My motor will be here tomorrow. Yippeee... I just finished taking off the KA. It's not that hard, however, I managed to break the AC LP hose on the firewall :(I guess it would not happen if I have another set of eyes. I did that all by myself. I was concentrating more on the PS rack lines.

Anyway, krazy, sorry can't help you on that. But be sure to post the solution if you did find it. No spark, huh? Hmmm.
