pairrothead01 Posted March 1, 2020 Share Posted March 1, 2020 Back again as I have a R50 project going on. 2003 LE 140,000 milesAs I was replacing the Water outlet hose and water control valve thermostat, I must have leaned ever so slightly on the fuel rail and the number 2 injector.I had somehow cracked the brown plastic/phenolic piece on the injector next to the big green O-ring.Found this as I was getting ready to put the fuel rail back. Big question is what are my options.Looked online and do not see that that piece is available as a seperate item.I see there are new injector available starting at pricey to god no......then there are the remanufacturers.Can I get one injector and just replace the damaged one....or will I have to purchase a matched set?Appreciate advice on best next steps vs most economical next steps.

colinnwn Posted March 1, 2020 Share Posted March 1, 2020 Matched sets are not required for non race vehicles. You are fine to buy a single.Remans were iffy on the old Maxima injectors specifically. I'd probably go for a new one. Sent from my SM-N950U using Tapatalk 1 Link to comment Share on other sites More sharing options...

colinnwn Posted March 1, 2020 Share Posted March 1, 2020 I expect it is not available in the aftermarket You can look on the exploded parts diagram on NissanPartsDeal.com to see if it is available from Nissan and if the price is any better than the whole injector.

pairrothead01 Posted March 1, 2020 Author Share Posted March 1, 2020 Update....found out the name of the part a broke......Pintle Cap.I have been able to locate this part in sets less than $20.Alternate option to consider.Set comes with filter/strainer for injector.Weighting the pros and cons of opening up fuel system.Going to ohm check all the injectors first, just in case the #3 cylinder misfire I coded, which started me on this project, is cause by the injector.That might be my push to open fuel system.Sent from my LG-K425 using Tapatalk Link to comment Share on other sites More sharing options...
colinnwn Posted March 1, 2020 Share Posted March 1, 2020 I've never done it on a Pathfinder. I've done it on a 1990 Maxima and a 96.I'd ohm all injectors and if they are in spec leave them alone.My 96 needed 1 injector and never had a further problem.The 90 had known coil insulation problems. I replaced one and had another go bad in 2 weeks. Then I ohmed all injectors and 2 others were out of spec. At that point I did them all.Replacing one pintile cap is reasonable. But I wouldn't expect to open it up for inspection and strainer replacement on all of them, without having issues getting it back together with brittle plastic parts from years of heat, gas, and oil exposure.
