ok. so i get home with my RnR exhaust, slap it in, and get ready for a test drive, and the damn thing wont start! it cranks, but it wont actually start! anyone have any ideas why? i drove from LA to san jose (about 400 miles) about an hour before and it drove fine, and after installing it the car no longer starts!

 

a ground? I don't see why it wouldn't start

 

We need to have more information to diagnose your problem. For example: what you did, what you took off and ect.

 

the only things i took off in order were:
1st o2 sensor
battery ground
fan
radiator

the rest was just the exhaust piping

 

why the heck did u remove the radiator when you were installing the exhaust? that tells me there is more change then you tell us... did you upgrade the fuel pumps?

 

try checking fuses, especially the fuel pump fuse. I blew that doing some electrical work which caused the car to crank but not turn over. Just a thought..

 

Best thing is go back and double check everything you did. I don't understand why you took out the radiator and fan anyways. As some said, check your fuses. Maybe you burned something when you took the battery ground out because it might have touched other metal parts of the car.

 

check to make sure the fan is plugged in and if so check the rad fan fuse

 

sorry the ac fan

 

Make sure you didn't inadvertantly disconnect the coil-pack wiring, and make sure you didn't blow any fuses..

BTW, if he got the O2 eliminator pipe, you HAVE to get access to the side of the turbo to remove the stock O2 housing.. thats probably why he removed the radiator.. Also check the primary O2 sensor, make sure its plugged in good and not damaged. Though I've never experienced this, I suppose its possible it may make it a non-start issue..

Also, disconnect both battery cables, take a close look at them.. (the positive cable has a fuse on it) make sure its not blown and reconnect the cable.. if one of the two wires on the positive post isn't making good contact, the car will crank but not start.. doublecheck the ECU fuse also under the hood.. another reason for a no-start..

 

Oh yeah.. make sure you didn't inadvertantly disconnect the MAF wiring while you were taking the radiator out..

 

yup..i had the o2 elim downpipe...i took a look over and saw that the second o2 was in pretty bad cond...last time i hire my neighbors to help.the o2 was pointed up, pinching the wires against the heat shield, and the wires were twisted. i was told by AAA that this will cause a no-start issue. i hope this is true =P
it was a huge let down after installing the exhaust after a 5 hour drive from socal and not being able to hear it purr
