My maxima is a 1992 SE with the VE30DE engine. It has been running rough and we have done several tests to find the problem. When doing the tests we found that the problem was in cylinder #1. We checked the the coils by disconecting them, and the sparkplugs and they were fine so the problem was the injector. We checked the injector with a multiple meter and it was not getting any reading while the others were so the injector is bad. We have been searching around and we found that the auto parts have remanufactured injectors. The injectors we currently have say JECS A4-600. The one at the auto parts are Beck/Arnley, Niehoff, and Python. I can also get a new injector or get one from a junkyard and get it cleaned. Could i have different injectors running at the same time? Or should i change the whole row? What do you suggest.

 

it doesnt matter as long as they r for 1992 MAXIMA SE....

 

reman injectors have a pretty bad rep, someone else can probably go into more detail on that. if you have the funds i suggest replacing the entire rail if you don't know how old the other ones are, it'll just save you problems in the longrun.

 

exactly if u have a budget change all of them....if not then leave them and jus change which u needed....

 

remans suck approximately as hard as Jenna Jameson. Pythons are as bad, or worse. Get new or get some from a JY. Test the ohms on the ones at the JY, of course.

 

my only suggestion based on experience: http://www.internetautosupply.com/ca...027-p-420.html

 

take some advice from me and get new injectors. There is a guy on this forum, I think his name is Bryan, he has the new one's you need for the best price.

I went throught 2 sets of b/s remft injectors over a 3 month period and they all began to fail one at a time. A few of them are still lgood but I eventually bought a new set.

You have been warned...

If youre on a limited budget regarding the purchase of 6 new units then buy used ones and have them cleaned and tested. I sent 6 out about 3 mnths ago http://www.witchhunter.com/. There are several other cleaning facilities but a tad pricier with RC Engineering being the most expensive.

I would suggest sending at least 2 extras and also leaving them in the rail for the facility to reinstall them for an additional charge. You will also need new O rings upon reinstallation and I suggest OEM's.

Dont buy reman. there is nothing anyone can rebuild on these units barring replacing the o-rings and testing them.

is your ignition rotor turning?

 

Did you take the distributor off for any reason during the process? It is common for people to reinstall them 180 degrees the wrong direction. If you did remove the distributor then consider that.

 

I just bought a set from fiveomotorsports. They appear to be factory - same color and exact markings. Paid about $450 for the set of 6.

 

$450 for 6, that's an excellent price for OEM injectors.

 

Doesn't say new. Rebuilts are still technically OEM

 

I'm also interested in the set that FiveOMotorsports is selling. They list them as brand new OEM made by JECS. Does JECS still supply OEM to Nissan? I wonder if they have made any improvements to these injectors or do they share the same flawed design as the originals.

Interesting, Wikipedia says JECS was a joint venture between Bosch and Nissan so that Bosch could get into the Japanese market and Nissan could use their EFI technology. Hitachi bought out the company in 2002 and it looks like a lot of their stuff now comes out of China.

I haven't read of the Bosch injectors failing, but you see lots of JECS remans. Witchhunter lists the JECS as a "problem injector".

 

The bosch injectors in some cases use an updated feed design.
if you do a little searching you will see pictures for comparison.

 

Thanks we replaced the malfunctioning injector with a brand new bosch. we got a pretty good deal on amazon. once we finished and cranked it up the car idled and drove perfect. Thanks

 

i am SOOO glad i joined this forum. i have been going back and forth with the idea of buying remanned. but now i know i should just be patient and save my money and buy new. and now i know i should buy BOSCH becuz of the merger and all that. thanks guys, you all rock hard.

 

It's a big chunk but it'll be troublefree for another 20 yrs....Those JK units never last that long!

 

just bandaids
