Tried searching, nothing definitive came up so here we go:

Ok so my 03 350z is finally at the point where I can try to start it. Problem is, it just turns over and over but never fires up. I was pretty sure the problem was the immobilizer so I had Z1 do an OSIRIS reflash and eliminate it. Reinstalled the ECU, went to start it, same problem. The red security light stays on when the key is in the on position. At this point I'm kind of stuck, Ive tried both keys and the valet key with no change.

I'm not hearing the fuel pump prime. When the key is turned to the on position one of the radiator fans comes on but not the other. Checked all the fuses and they all look good. My fusible link has 2 blown fuses which I have bypassed with a bit of wire and an inline fuse, not sure if that makes a difference but I'm planning on ordering a new one anyway.

Basically I need some help from you fine folks to figure out what my problem is. If there's any additional information you need from me just ask. Im open to pretty much all suggestions, I just wanna drive this damn thing hahaha.

Thanks

 

i would start here

 

Was my guess as well. I tried switching out the relay and didnt hear anything different. The red light being lit is the most bothersome to me. From what I understand that usually means theres an ECU power or NATS problem. Nats shouldn't be an issue since the immobilizer has been eliminated but I don't know if having the immobilizer disabled causes that light to come on anyway.

 

Pics of the rigging please

Fuel pump fuse still good? Its at the bottom of the fuses in the the set inside the battery cover.

No fuel....no run.

 

Yea checked the fuel pump fuse. I'll post a pic of the ghettoness, give me like 2min.

 

 

Spray a little carb choke and throttle body cleaner in your throttle body and see if it wants to start up.

 

Go to Nissan and get another OEM fusible link. Yes, that can cause ECU failure jury-rigging with a replacement wire and in-line fuse.

You might also want to find out why it blew in the first place.

 

Local dealership wanted $103 for a new link. I LOL'd and left. Going to order one asap.

Thanks for the help everone, I really appreciate it. If you have any more ideas post 'em up. I'll update on progress when there is some.

Edit: I found out why it blew a while ago. Stupid mistake on my part that has been remedied.

 

I think Z1 sells that oem fusable link for a decent price.

 

Yea much more reasonable. If they have one in stock I'm gonna go grab it today.

Edit: fusible link should be here Monday or tuesday.

 

Fuel pump is not coming on. Tried different relays, no difference.Thoughts?

 

Does it have power going to it? Might just need a new fuel pump... If power is going to it, if no power is getting their fuses relays ground problem

 

Ok so theres a white plug near the ecu that was apparently a bit loose. Finally got it started, hooray, then major oil puddle from the passenger side. Top of the alternator on down, any ideas?

 

VVT solenoid? There bad for leaking if gaskets not perfect. Along with valve cover gasket. Start from the top and work your way down little by little. Also check your oil filter, if it's loose or double gasketed them suckers will SPRAY (ask me how I know)

 

And how would you know

 

Got a face full when i double gasketed mine by accident.....had a fellow tech start it up to check for leaks and (yeah that was my first week on the job. it was a looooooooooong week)
