I will try to condense this to the short story:

My 1995 Maxima sat up for two years....I wrecked my other car and had to resort back to this one for financial issues.

After changing the battery gas, etc it ran perfect for 5 months.

I went to start the car and it has always cranked within 3 seconds, despite 270K miles. I parked the car and the next time it took over 10 seconds to crank up but then ran perfect. Next stop Walmart.....took over 30 seconds of cranking to start!! Once started it ran perfect.

I decided that I was not going to shut it off again until I got home. I pulled it in the driveway and turned it off. Immediatly tried to start it again...No go.

Being a weekend mechanic I did some research, the fuel pump was not kicking on. Changed that out.


Eventually I had it towed to my mechanic who is very good. After a WHOLE LOTTTA trial and error she found that the computer was not getting power. She changed out the relay for the ECI. Still no power to the computer, however it does click to create a contact.

So that leads me to believe the current provided to the #3 terminal on the soilnoid is not providing enought current to run the computer. But where does that come from?

Also I might add that I have had problems with the ignition switch and have to accelerate into the key to get it to turn over.



If she applies power directly from the battery (bypassing the relay) to the line (red/Silver dash stripe) that goes to the computer it fires right up.


I don't have access to all the wiring diagrams so any help would be appreciated.

* on a side note she did notice that apparently while the car sat up a rat took refuge in my car and chewed up a few wires....but nothing is bare or grounded out. All fuses where checked and all good.

Any help or advice would be appreciated because I am already driving this because of being laid off and without a job I can't even apply for a job.

I have a few pictures, but I doubt they would help.

Thank you,

Peter


So here is my hypothis.

 

Opps...last part didn't post. Hypothosis. The block for the relay isn't getting enough current to run the computer. But I don't know where it gets it power from?

Does it run through the ignition switch? Can I run a cable from another junction block to provide the correct current? I don't know what the wiring is on this relay?

25230-79981 Is the relay.

 

Does anyone have a wire diagram that I can find for free? Thank you!!

 

download the factory service manual. Link is in the stickies or FAQ

 

Current flows from the battery, through fuse 57, through the connector to the relay box, then through the relay to the ECM. Page EC-99 in the FSM.

If a rat gnawed the insulation off wires and the car sat for two years, there could be so much corrosion somewhere in the circuit that very little current flows even when the relay switch closes. If that's the case, it must be upstream of wherever she connected her jumper wire when she bypassed the relay. Start there and follow it back to the battery.

 

That is what I was afraid of. I guess because it ran fine for so many months that it couldn't just be a wire, but I suppose as the car giggled along it may have broke more wires. I about crapped when she showed me the rat's nest in there and the nawed wire harnesses. Thank you for all the help!!

 

Okay I will look for that.. She had Alldata but it doesn't provide where all the wire run or colors of wires.

 

I managed to find a FSM for a 1998, can you direct me to where I might download FSM for my 1995 or pm me to find that page? Thank you.

Thank you guys for the help....will keep you updated...

finally found this link too

Excellent free source for wiring schematics - provides pin and wire color info, but not physical location for wires, splices, etc.
