Re: IPDM - ECU relay problems, symptoms and solution.

Is this an intermittent problem or is your truck down hard? Are you using a scanner capable of checking communication between the different control modules (computers)?

I had an intermittent "Crank, No-Start" problem that took months to figure out. If it's down hard that should make it easier for troubleshoot. Using one of those capable scanners is important though since any breakdown in communication between any control module can keep the truck from starting.

2005 Nissan Titan 4x4 Crew Cab with towing package


Started off Thursday evening myself and a pretty reputable mechanic changed front pads and rotors on my truck drove the truck next day it run fine. Came home and parked the truck to come out the next morning to a truck that would Crank but would not start. Acting like no fire or fuel, towed it to the shop here is what all we have replaced.

Fuel pump has been replaced ( plugged the fuel pump into the harness to make sure it would come on prior to installing and it did ) Installed the pump in the tank hooked the battery back up pump came on the 2 seconds and shut off. Truck tried to fire once After that the pump will not come on at all here is a list of what has been done

New Fuel pump
Run the Ipdm test and not one but (2) modules pass the test (horn, wipers,fan, fog lights,headligts etc Not only 2 modules but 4 relays also
Crank Sensor New
( spray with staring fluid it will fire) Pump is not running
(3) different Keys tried
Anti Theft light blinks as normal

Something has the fuel pump shut down and will not allow it to run. Could this be the ECM ( Engine Computer )
Is there a way to test or reset the Anti Theft System

Thank you in advance

John

The truck is Completely dead. As for the scanner I am trying to find someone that has one capable of looking at the communications between the ECM, IPDM however it works. Drove it home one night got in it to go the next morning to nothing but cranking with no start.

Re: IPDM - ECU relay problems, symptoms and solution.

Did you swap your fog light relay with the IPDM relay?

Re: IPDM - ECU relay problems, symptoms and solution.

Thank you for all of the suggestions on fixing the Titan It is back up and running however it was a nightmare!!! Final solution


Not 1 but 2 bad Delphi fuel pumps from Advance auto parts. The pumps would actually come on and run however they would not pump anything at all. They were garbage. The man at the parts store argued with me saying that there was no way 2 of them were bad. I had to show him a video of the Napa Fuel pump running and pumping fuel before he would admit he was wrong. That got the truck up and at least trying to run. Truck would crank and stumble like it was flooded. Long story short after 3 scanners were hooked to it none of the master techs was able to figure it out. It threw a P0123 and a p0223 code pointing at the Throttle body. Put a new Throttle body on it and the codes were still there. For some reason the codes were not being cleared from the computer it developed a memory of the codes but yet it would turn the Check engine light off when they were cleared. For kicks and giggles I disconnected both cables and held them together for about 10 mins hooked them back up and what do you know. The titan came back to life running like a dream IT fired right up

Original fuel pump died! Then after 2 Bad pumps and a computer holding a memory of 2 codes caused this truck no to start and run


Thanks again

Re: IPDM - ECU relay problems, symptoms and solution.

Should always be removing the negative battery cable when preforming jobs that you are unhooking and plugging connectors back together. May have took care of your memory code problems.
At any rate glad to hear you got it running and sorry to hear of your troubles with trhe faulty pumps!

Re: IPDM - ECU relay problems, symptoms and solution.

New kid on the block and not very mechanically savvy! My 2008 Titan Crew XE will crank til the cows come home. I can hear a 2 second hum at the fuel tank when key is turned, but no ignition. I tried swapping the relays as many of you recommended, no change, still just cranked with no firing. Tried spraying starter fluid into the air intake and no results. What do I check next? It has 169,000 miles on it and runs like a top when it runs, she just won't fire. It had slowly been getting more difficult to start. Now it is dead in my garage. Any help is appreciated. Make it simple. My business is the Bible, not motors.

Re: IPDM - ECU relay problems, symptoms and solution.

Bought a new relay on Amazon from Conyers Nissan for my 2004 Titan and had it changed out in 5 minutes. Started right up. Nissan Relay - 284B7-CW29E https://www.amazon.com/dp/B00CMTONK0..._yz9Gyb189280Q

Actually 3 days in a row now , idle is fine, everything is normal. 4 DAYS IN A ROW at 8pm when I goto lunch (I work 4-midnight) it won't start, no crank, no kick from the starter but plenty of power for the lights windows etc... I swapped the Relays yesterday but it still is did it today.... Each night after playing with it it seems to start up at about 12:45 am... WTF?? I'll say this I was In Pismo last weekend and did a little off roading, and some towing if that makes a difference... But I'm typing this from my iPhone in the breakroom, and I really want to fix this problem.. Could it be anything other than the IPDM? I thought perhaps it was the transponder key but I've tried all 3 of mine and still no start.. Also my truck is a 2007 4x4 so it's a little newer, anyone with an 07 or newer had trouble with the IPDM?
I just had to ding in and say if that picture is you, you are beautiful and hope you will cheer me on when we all have the first track vk56 shootout!

Its the IDPM

Re: IPDM - ECU relay problems, symptoms and solution.

New member here, though have been reading posts since I bought my 05 titan LE in Jan 16. Have been experiencing the same problems as most in this thread, stalls when driving, sometimes put in N and will start, sometimes not. Pull over rest a few mins. sometimes will start sometimes not. However, also had the service soon light come on and had a code P0340, camshaft position sensor. Was all set to change out the ECU relay, which many posts suggested, but thought I'd do the fault code first. $137.00 from the dealer, not, so searched and bought one from O'reillys for $28. Specs met OEM so I bought it. Was easy to swap, biggest problem was unhooking from the harness. Word of advice you don't just push "down" on the green tab you must push all the way in till it clicks, that releases the CPS. took a while to figure that one out. Anyhoo, so far so good, though this is just day one. Drove around for 10 min or so stopped for a burger, restarted just fine no stalls. So if you experience this problem and have tried the ECU swap, you may have to look into the CPS route also. Now I have to figure out 2 other concerns 1) passenger elect window won't move, and 2) that clicking below the dash, has to do with a vent cam or something like that. BTW just love my titan, most solid truck I've owned.

Re: IPDM - ECU relay problems, symptoms and solution.

CPS and CPK often don't throw a code, and are cheap/easy to change if suspected. The Dash has a valve that has a delayed action, noted by many. If all is working, don't worry. Glad you like the Titan!

Well then if that's the case then it's all the more reason to check the CPS. I've read thru all these posts and so many people switched/replaced the relay and or the whole board and it didn't solve the problem, so what does that tell you what to check? BTW I have the original white board in my truck. It's been over 2 weeks now and had no issues with stalling or starting, works perfect. Also fixed the pass window problem. Took the motor apart and was a bit of powdered residue inside. Cleaned it up and noticed one of the brushes was stuck, so used some electrical contact cleaner and worked the brush in and out to free it up and works just fine now. This, however is just a temporary fix as the brush only extended out about 3/16 of an inch or so and will probably be wearing down at some point. As far as the noisy clacking in the heater box, it only happens at full A/C or defrost positions. An annoyance but I think I'll just have to live with that since it doesn't appear to be an easy fix unless I want to take the whole heater box out.

Happy truckin'
