Interrmitent Starting Titan

jtrick · Dec 9, 2013

Everyone, been a minute since I have been on here due to personal issues. I need your help.

2008 Titan SE, 72k miles.

I drove from Georgia to Ohio on Thanksgiving day. I drove back this past Saturday. No issues with the truck. Went out this morning to crank her over and all I got was a truck trying to start, but wouldn't kick over.

I tried to jump the battery, no luck. I took the battery to O'Reilleys and sure enough it was tested to be bad. Brought a new battery back to the house, hooked it up and tried to crank the truck over. No luck. She tried to crank but would not turn over. After about 5 attempts she cranked.

1 hour later I went to start her up and same thing I had before the new battery. She cranks but will not start. This is sporadic. I eventually got her cranked and then went out and tried again. No luck.

My buddy got under the truck and I turned the key on and heard the fuel pump kick on.

Anyone have any ideas on what could be my problem?

You check your cables to make sure they aren't corroded? I've seen negative cables get pretty bad. While you're there, double check your posts are making good connection with the terminals.

Thanks JBowles. Im sure my cables are tight and I cleaned the little but of corrosion I had off before I hooked up the new battery.

Just for the hell of it, try another key, if you have one. Can't hurt.

I had an intermittent no start in my X, and it ended up being the crankshaft position sensor.

I tried both keys I have, same issue.

Is IDPM my culprit? Dangit.

SteveK · Dec 9, 2013

Did you make sure there was a full charge on the battery before installing it?

engine will turn over but it will not run? it might be ipdm or crank shaft position sensor as stated above. no check engine light or code?

Titan's along with Armada/Frontier/Pathfinder/Xterra all suffer from a bad ECM relay. Does you check engnine light flash when your cranking? If so get it to the dealer, it should be covered under a recall (PC068). The relay is in the IPDM box, the relay is pretty cheap. We've seen Frontier's that "arent affected as per Recall info" still have the problem.

Part number 284B7-CW29E $2.18 (plus taxes).

Good luck!!

If it cranks but won't turn over, my recommendation is to look at the fuel pump.

As 37L1 showed, swap out the fog light relay first. If it was the IPDM though and completely died, there would be no turning over. If it was failing, it would go into safe mode and you wouldn't be able to drive at normal speed.

Could also be a bad MAF.

u can rule out crankshaft position sensor, I had that and my truck would start and drive, u may have a ground or an exposed wire somewhere, recently had a buddy with similar issue different car and it was drawing more volts than it was suppose to which was a ground in the electrical system, u check ur starter? ****ty thing is u have to pull off intake manifold, did they check alternator when u were there with the battery? are u getting any codes?

jtrick · Dec 9, 2013

Thanks everyone. I can hear the fuel pump click when I remove gas cap and turn the key to on so I don't think ( hope) that is it. I am not throwing any codes. I will check the relay out tonight. I might pull the MAF sensor and see if that is it. I did notice at idle that she idles a bit rough intermittently. The rough doesn't show on my tach I.e. The needle doesn't move.

My experience with a starter going out is getting a click when I turn the key not trying to crank over.

Sorry for all the posts but I am on my phone. I have a bullydog and air flow appears normal.

I'm telling you check the relay, we rarely ever sell fuel pumps (senders are a different story). look to see if the "
check engine light" blinks during attempted start up. IPDM's used to be the fix, till they realized it was just the ECM relay causing the problem (which you used to not be able to get) until they came out with the recall.

Thanks for everyone's help. I bought a ECU relay tonight and it took me 10 minutes start to finish to replace. Titan starts up like a champ now. Nothing feels better than a 4 dollar fix for a Titan that won't start.

SWEET!!! Glad it worked out for you!

I'm having the same problem out of my 2008.5 94850 miles on it. I have had the relay replaced recently. And still every once and a while it will crank and no start. It has been doing it for about a year now intermittent. No rhyme or reason no pattern. Full tank of fuel empty tank am pm does not matter. I have always been able to crank it after a few attempts sometimes several but it always does crank. I do have a bully dog on it just installed the latest software update. Any help would be thankful. I will state it only started this, after I installed the bully dog programmer a year ago. No eng codes either, fresh interstate battery clean greased terminals. ???????????? Any help will be greatly appreciated.
