Injector service?

[2002jm]

Well, been sick for awhile, so the 323i got put on the back burner. Did have someone test the electronics and we noticed when the car got warm the ecu went flat line for the injectors.
They were just open all the time. So now I have a new ecu and hopefully we will get the h23 back on the road this week.

not sure running some cleaning fluid through them changing the o-rings, filters, caps etc classifies a rebuild lol

Lol

its very misleading

That's highway robbery. The going rate is about $15 to $20 per injector to rebuild and flow test them.

As I found out recently it is not worth paying a company to clean injectors you are way better off installing new ones, fyi I was charged $40.00 for cleaning fluid for each injector.

Hook up a fuel pressure gauge and you'll know.

I am having a crank no start problem and I am wondering if this might be a fuel pressure problem. Has anyone here ever had this problem? Could it be spark plugs??

On several occasions my car hasn't started but when I hot wire the Fuel pump to a Battery and have it run for a few seconds, the car starts fine and runs without issue. Anyone experienced this ?

Of note (I don't think it's a fuel pump issue, I have a new fuel pump and changed it thinking that my fuel pump was dying).

I have used RC Fuel Injectors in Torrance, CA, to rebuild my injectors. They provide a written before and after report with detailed information, including spray patterns, etc. The shop was founded by the late Russ Collins and does great work

Hi. Thanks for all the good information. Ordered a new set; old ones jiust look too bad and dirty to me.
Hope to get them in and get this hartge h23 tribute on the road.

As others have stated, fixing a stuck injector is going to be difficult to impossible. I will also mention a note with four-pintle injectors... when running them in my injector machine, I have noticed that all tend to spray directly downward. Our stock injectors actually spray the fuel at a slight angle towards the back of the intake valve. Realistically, if yours are leaking, I would say that it is time for a replacement set.

I practice prevention.
First when its hot outside and the car is hot lift the hood. That "corn" gas will get sticky.
Second , once or twice a year use
Sea Foam additive , others are junk
Third, new filters (duh) and avoid short trips (duh)
Fourth .drive like hell.

Never had a problem.

I cleaned the injectors on my old 325e myself. Took them out and blasted them with brake cleaner using methods I found on YouTube. Kept them open with a 9V battery. Threw on a new filter and pintle cap. Car ran a bit better

I did the same shit...9volt battery too.Hooked up a fuel injector can to a hose that fit on injector. Injectors seem to fire good. New pintle caps and filter too.

Losing pressure after 20 minutes probably isn't a problem anyways. Running rich would be, but that could be a lot of different issues.

i went with a four pintle injector on the i, more modern and a touch more efficient, i'm sure there is an equivalent for the 323i

[MrBurgundy]

I'll echo the opinion on just using new.

I dicked around with used injectors.. never was happy with them. Got the updated bosch injectors and took any injector problems out of my mind
