Guys I need your help. 6 months and no go :(

[NEED4BOOST]

Okay here's my dilemna. I have an S14 sr20 put into my 97 240sx. everything is in and plugged up. Now the only problem is that the motor is not turning over at all. Everything in the car works lights accessories, everything except when I turn the key. When the clutch is pressed in and the key is turned al the all I get is a single click from the fuse boxes.

I don't understand what is going on because its obviously electrical. Anyway I tried to jump the battery but still the same thing. I took the starter off and got it tested and it was strong. I checked fuses and they were all good. Relays I'm not too sure on how to check them.

I didn't half-*** the swap all the parts are either greddy, hks, blitz, Koyo, etc. you get my drift.

Thanks guys,

Seth

[NEED4BOOST]

also I have spent 30 hours just trouble shooting and double checking what I have done and I know I'm over looking something. I am almost positve that it's something stupid but I don't know what it is.

[UsedToOwn240SX]

Was your car an auto before the swap?

[NEED4BOOST]

nope

[MojoMan]

Make sure the ecu is correct. Check the big fuses under the hood, and your right, it proly is something simple, it always is. Make sure the nuetral switch is good on the transmission and that it is hooked up. If you want, have someone hold the key in the start position while you take a screw driver and cross the points on the starter to bypass the ign signal to the power wire to try and start her up. That doestnt fix the problem but it might put you in the right direction. Get a multi-tester and make sure the starter is getting power and probe some of the other power (main) wires. I hope this helps a little.

[NEED4BOOST]

Thanks I'll definitely try that!

[slw240sx]

have you tried to hot wire the starter? maybe the starter is dead

[MojoMan]

have you tried to hot wire the starter? maybe the starter is dead

Thats basically what I told him to do. It sucks but it works. I use to have to do this when I had my v8 in my 280z. It was definitely easy to reach though.

[slw240sx]

well if you do this and it starts then your ign signal isnt there or somthing to that nature, if it wont start then dead starter buy another and try it out! this should be a simple problemn to fix

[S13240]

He did mention that he tested the starter and it gives a strong signal so it couldn't be it.

[slw240sx]

but did he hot wire the starter? cause if you put juice to the starter motor it should turn over the car! if the key is on it should start , there fore would lead me to think its missing a starter signal wire! my friends SR from heavythrottle was missing the starter signal wire along with a slew of other things that it needed to start up

[cybin]

If your getting a click out of the fuse box sounds like a short circuit. Are the wires on the starter right? ie Don't have it hooked up backwards.

-cybin

[NEED4BOOST]

Cybin since you mentioned it, I did notice that there are 2 bolts on the starter. One of them if I remember correctly has a wire or something on it. I have the 'hot' wire (with the red rubber cap) on the bolt without the flat wire under it. Could that be it? I hope I explained that well enough to understand. Does it sound that I may have hooked up the hot wire to the wrong bolt on the starter?

I would take a picture but my car is an 1.5 hours away from where I live.

Thanks guys,

Seth

I just called Turbo Tune in Greensboro, NC and the guy I tallked to mentioned that I may have not properly grounded the car and thats what may be resulting a click from the fuse box. He mentioned something about not enough amps being sent to the starter. Sound right to anyone?

[MojoMan]

Yes thats exactly what it sounds like if it doesnt have enough cranking amps. There are a few engine grounds that you need to check. And it doesnt matter which bolt the ground goes to on the starter just as long as it goes to one of them. Basically you just have to complete the curcuit.

[NEED4BOOST]

I just called Turbo Tune again and they said that I just need to go ahead and run a cable off of the negative terminal straight to the block and not to mess with trying to complete the circuit through the body of the car. So I'm going to give that a try and see what happens. Mark up at Turbo Tune mentioned that the 240 is a unibody and the spot welding is interferring with the circuit.

Well I'm gonna keep my fingers crossed.

[SET240SX]

Sounds like a neutral switch or a clutch switch to me. I think there are 3 switches that allow the starter to engage and all of them have to be in the right position. I had to change the switches on my s-13 swap. I am at work now so i can't look at the wiring diagram in the fsm and tell you how to test the switches without removing them from the transmission. But it is really not hard just need to know if they are normally open or closed.

[cybin]

The reason I menchen the starter wiring issue is I had the starter wired wrong on a 1978 MG Midget.

The clicking noise sounds like a dead battery to me or the grounding issue.

[TruboostPerformance]

do you hear the fuel pump cut on for three seconds when you turn the key on? Sounds electrical deff like everyone said, if you don't hear your fuel pump cut on when the ket is turned all the way on, then double check with a multimeter that you have power from ignition to the fuel pump relay as well as all the others that require power from the ignition...

[Touchdown038]

Yup... you might wanna check that you're getting fuel. Unhook the send line and see if fuel comes flying out. If so, gotta be something else. Oh and make sure you don't smoke when you do this

[Vrtgrumpy]

T0o much to go over here. If its not going call me after 4pm PST and I will help you... 619-449-4748

[NEED4BOOST]

Vrtgrumpy thank you very much for your phone number...I will be calling you today!

As far as my fuel pump, yes it is coming on for 3 seconds when the key is turned all the way. The fuel line is pressurized. I have taken the cable for the negative terminal and ran it to one of the bolts on the bell housing. Then I tried to start the car again and nothing but that single click. I think that it can only mean that my neutral/clutch sensor is bad. Also I noticed that my reverse lights don't work. So it may just be those sensors are bad.

Any other suggestions would be greatly appreciated!

thanks,

Seth

[hokiruu]

This is scaring me. I am putting in my SR next week myself but I am starting to have doubts about getting it running. Lots of great info here though thanks guys. Good luck with the car!

[NEED4BOOST]

don't worry these guys will help you get it running. They have helped me so far. All you have to do is ask

[hokiruu]

That's good to hear. I will be eavesdropping on this thread frequently, because we are basically doing the same thing. PS: I like your style!

[NEED4BOOST]

Hey Hokiruu if I can help you with any advice with your swap let me know. I did it myself with the aid of NICO so I have some experience.

On a side note I will post pix of the car when it is near completion. What am I talking about this car will never be finished its a freaking race car project. I'll post pix when it is running Hopefully in the next couple of days....

[hokiruu]

awesome! I can't wait to see. I myself have already run out of money on this project, so I am scraping the bottom of the piggybank until I can sell my KA and its respective parts. All I need now are gauges and a BOV. At least for the engine that is...I still have a TON of other things that need attention on the car. Good luck!

[Siddhartha]

This happened to me in my Fiero. EXACT same thing, though I dunno if it'll help. Make sure battery terminals are clean. Take them apart, remove any whitish powdery stuff (corrosion) around and inside the terminals. This happened to my car recently and the terminals were dirty. It seems like a basic thing, but sometimes these things are overlooked. I know I overlooked it for a long time.

Not trying to insult you or anything, just putting my two cents in.

HTH

[sr20det]

i have the same problems with my car but guess what i found out what the problem is. wanna know its my scared you. anyways, for my car when it clicks like that by the fuse box when key is on ign. The problem is my ECU is fired . hehehehe. see if any of you friends have an extra ecu and test her up. for me when i got a new ecu it starts rite up. this all i know, and yah try to check for fuel and sparks. ehehhehe PIECE OUT..:ylsuper

[NEED4BOOST]

Okay its always one thing after another! I get the engine to turn over a few times to circulate the oil. I plug the ignitor chip in so that I can run the car, well the damn thing wouldn't start. The starter engages but wont turn the flywheel. It tries because it will make these half *** revolutions. So I called a couple of places and an assumption that the starter may be bad arose. So I figured lets push start the car. I put it in gear, clutch down, and 4 people pushing....BUT the car didn't move! it was locked in gear with the fawking clutch down. I checked to see if the slave cylinder was working properly. Yep it was mounted fine and pushing on the fork pretty well. All I can conclude is that there is something up with the clutch and its no allowing the motor to turn over. I have an ACT 6 puck. not one mile on the clutch also a stock flywheel.

I am giving up on this damn car and I'm paying someone to finish it. I need to start putting it on track and I have lost a lot of track time already.

Any suggestions???

Thanks,

Seth
