I got in a wreck last week and totaled my 240. Luckily my Sr was not harm at all (started and drive fine) and now i'm up for another motor swap. Anyway...here's the problem...i got the swap done everything is hook up correctly but the car wouldn't crank. I know it's something really stupid like grounding..so i checked it..nothing happenned still. What could this be guys? any suggestion on this? If possible can someone listed all the SR's grounding just in case i missed one? I did hear the started click but won't turn over

BTW - the swap is the SR redtop to S13 and yes, the Harness is wired correctly

Thanks for your time..

Is the engine turning over? If it is, and you have a fuel pressure regulator, check to make sure that it is getting fuel. If it is, then you most likely have a problem with your spark. Start with the wires and trace back from there. Good luckJosh

You said your starter clicks but the motor doesn't turn over? So the starter is engaging? Just making sure your battery isn't too low, your clock would go out when you try to start if that was the case, that would be your "something stupid".

If thats the case I just had this problem only I had just finished driving my car, I cut it off and 5 minutes later I went to start it again, nothing. We pulled the starter off and took it to a shop they said i looked to perfect to be broke. So I put it back in and it started right up. I searched this when it first happened to me and I read somewhere that it has to do with the black wire coming off of the solenoid that connects to the starter itself. you may wanna try to move it back ad forth and try to start again. If it doesn't work pull it out, inspect for anything out of the ordinary. May have just gotten a dirty ground. Good Luck!

Have the same problem every once in a while, all I have to do is wiggle the negative batery cable back and forth and it starts right up.

well....i took it back..the clicking noise isn't from a starter and the car didn't turn over...I checked all the fuses and it seem to be fine, the fuel pump works. I KNOW THERE's NOTHING WRONG WITH THE MOTOR....it was taken out from a perfect running car.

I also read up on Heavy Throttle's FAQ and they say that turbo timer wiring could cause this problem? anyone here have experience with this?

Thanks

The clicking noise you hear was probably the relay for the starter, Blue box in the corner behind passenger side headlight. Did you try to wiggle that wire? Or take the starter out? Or did you just figure the since noise wasn't from the starter so thats not the problem? Come to think about it my noise was from the relay.

I've never heard that before but heavy throttle is a really good source. What timer are you using? I've got the newer model GReddy and that's the first time it has done it in the 8 months since I dropped in my SR.

just because your fuel pump is working, doesn't necessarily mean you're getting pressure. the FPR regulates pressure.

Now, did you pull any codes from the ECU? Codes will tell you what's going on. 9/10 the problem is electrical, and the codes tell you what isn't working.

Are you reading your plugs? Go crank it a few times and tell me if they get soaked in fuel. Also, check to see if you're getting spark. The easiest way is to pull the plug, pop it back in the coil pack, and rest the plug on the valve cover. Then, as you crank the motor (please take your hand off the valvecover and plug when doing this), check to see if the plug is igniting. Repeat for all coil packs.

Next, is the motor timed in? Did you mess with the CAS at all? Did you pull anything off the motor? If so, double check that it was all reinstalled correctly.

Finally, check for blown fuses. We often overlook fuses, and when they blow, they can take the whole house down.

Triple check your wiring, too. It never hurts to make sure everything is wired in properly.

I just spent 2 weeks diagnosing why my motor wouldn't start after I had done a timing chain job on it. I went through every step plus more that I just listed for you, trying to figure out why i couldn't get it to start. In the end, the CAS was 180 degrees out, and even though my timing looked ok, it was firing on the exhaust stroke, and not the compression stroke.

I would say take your starter off and examine it. If all looks well you can take it most auto parts stores: AutoZone, Advance Auto, NAPA, etc. All of them should do testing for your starter. If your luck is like mine(dumb luck) it'll start once you put it back in.

If they say its good then the problem lies between the starter and the relay, the fact that you can hear the relay clicking is a good thing, at least your relay works. Check that little black wire, goes from the solenoid to the starter, and make sure you clean the terminals for the starter and the bellhousing of the trany where it bolts to.
