i need help.. my sr dont start. pleaseee - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

mauris13 · 06-08-2009, 12:41 PM

well 3 weeks ago i was just trying to drift in my 240 and then the car just turn off and didn't start anymore. the fuel pump was working and i had spark. then i buy the cas because a mechanic told me that was the problem. but wen i put the new cas same thing didn't start but now the fuel pump was not working and i had no spark. my ignitor chip its working so i don't know what the problem is. pleeaseeee HEELLPP!!
one more thing... i check my ecu and it's not getting power. my fuel pump fuse its working but the next one its the eccs fuse its no getting power when i turn the kkey on. help

check for compression, correctly timed spark, etc.

if your ecu isnt getting power, then look in to why it isnt. because i *think* that's a pretty vital piece to your car running.

good luck

ECCS is the FLT ATL are the two ones that can blow your ecu. Check the fuse for continuity. If there is, then ECU might be friend. Sounds like you shorted something.

mauris13 · 06-08-2009, 05:28 PM

i check the eccs relay located next to the battery and its no getting power. with the key off it shows ground but with the key on it doesn't show power stills ground... you don't think can be the harness wiring?

JohnnyDrfiter22 · 06-08-2009, 05:39 PM

crack open the ECU and check to see if its fried

mauris13 · 06-08-2009, 05:45 PM

how can i tell if its fried or not? or is it just obvious

flip3d · 06-08-2009, 06:31 PM

Smell it. See if anything is burnt.

slider2828 · 06-08-2009, 07:16 PM

Opening it doesn't always tell you.... Wait its a relay and you get 0 power to any of those relays? Then also you when you key on, you don't hear any clicking on those blue relays either for the ecu? If S13 relays are at the front of the passenger side, if S14, relays are inside next to the ecu.

mauris13 · 06-08-2009, 09:05 PM

only the relay that is not working is the eccs. its the relay that is next to the batery. and the others are working good. so i don't know why is just the one of eccs the one its not working.

slider2828 · 06-09-2009, 12:08 AM

Maybe the relay went out, replace it with one of the same color ones and try it....

mauris13 · 06-11-2009, 10:50 AM

already did that.. and same thing.. don't start.

slider2828 · 06-11-2009, 11:26 AM

Get another ECU and try it.....

Projectenzo · 06-11-2009, 11:41 AM

Check that your battery has 12 volts on it. your car won't start if it doesn't, if it doesn't crank then check your clutch interlock switch located under you clutch pedal.

mauris13 · 06-11-2009, 11:57 AM

what does the clutch interlock switch does? do you think thats why the fuel pump and the skpark dont work?

slider2828 · 06-11-2009, 12:32 PM

Nope clutch interlock will stop it from starting, but DOES NOT stop fuel pump priming when ignition is in the on position.....

mauris13 · 06-11-2009, 12:45 PM

ohh ok thanks.. now i don't know what else i can try to see if my sr start. i have one month that the car don't start.

slider2828 · 06-11-2009, 02:37 PM

try another ecu definitely....

mauris13 · 06-11-2009, 02:53 PM

do you mean to buy a new ecu? mm.. i'm going to try take all the harness out and chek if its all conected right. and if its right i think i will buy a new ecu. or can i put one of my friends sr's and then chek if its that the problem..

sc ka24e · 06-11-2009, 03:00 PM

just make sure its the same # on ecu

mauris13 · 06-22-2009, 11:51 AM

hey thanks everybody finally my car its working.. the problem was a burnt circuit on the ecu.. i really appreciate your help..
