First time posting here... so thanks for you help in advance.

Have a 1999 QX4 w/ 150k miles. Love the car and hopeful to get some more mileage out of her.

This week I cranked the ignition, but the engine would not start. She was admittedly low on fuel, but doubt she was empty. I finally got her turned over after three tries (waited a few minute between each try), and immediately filled her with gas.

Began to go about my errands when she stopped accelerating at about 40 mph and made some noise like a muffled backfire from the rear part of the vehicle. Wasn't really sure what to do at this point, so I pulled over and checked the spark plug connections while the engine running. All seemed secure. Hopped back in and eased her on the highway. I didn't get her above 60 mph and she didn't seem to have all her normal V6 power.

Got her home. Lucky I think.

She now is back to where I turn the key and she is cranking, but will not start at all.

At first I thought gas, then the starter when she didn't turn over, then when she nearly cut out while driving I really had no idea.

Any ideas? I'd be extremely grateful.

Thanks.

You might need a new fuel pump and control unit if your truck has one. I am sorry I can't help you more because I have a Q45 not a QX4.

You can consult the service manual to see where the parts are located and for more help: http://Nicoclub.com/FSM

You can try this guy here to see if he has a fuel pump: http://stores.ebay.com/emgeepa...esc=1

If not try Infiniti Of Scottsdale because I only trust OEM part when it comes to doing such a job.

Ended up being spark plug related. They swapped these out, oil changed, did some sort of system flush for 400 dollars. I wish they would have bought me dinner before they bent me over... unbelievable.

They love to push those "flushes" as they are pure quick easy money makers- really known as "wallet flushes"

Who did the work? Love to know so that I can avoid them. Plugs?

Take is back if they didn't use the OEM specified NGKPFRG-11 plugs or you could lose your engine.

"Flush" and "Service" are code words that cover almost anything more than an "Inspection." May consist of nothing useful at all.
