Ok guys. Got a 1.6l 16 valve. Seems I got a bad injector. Can't give it much throttle until u get it wound up. Code reader said bad injector. Is there any easy way to find which one. Any injectors I can grab junked that might work other than original.
-
I dont have that engine but on other engines just un plug the injector and find it that way
-
On the 16V suzuki engine the injector plugs are damn near impossible to get to without removeing a whole bunch of other parts first. Maybe you can take a look at the plugs and look for differences in color.

A quick way to find a dead hole that may point to a bad injector is to spray water on each individual exhaust runner and see which one is cold... Of course you need to be able to see each runner separately and don't wait for the hole manifold/header to get heat soaked then all the pipes will be warm... SO, start it up let it warm for 30 seconds or so and spay a fine mist of water on each tube close to the head. "good" cylinders will boil/steam the water off while a poorly runing cylinder will not... It'll take you longer to read this and find a squirt bottle than to do this test.
:)
Good luck, Eric
-
Fine bit of testing wisdom there Eric. ;)
-
Ill try that this evening. Thanks. Any other injectors I could use?
-
Ford Escort uses a Bosch style injector and it's the right size to be a replacement
but you would need to replace all of the injectors, not just the one unless they
are identical in flow to keep the engine tuning with the computer on track.
If you have one larger injector and it is causing a rich situation it could make the
computer lean out the other cylinders to offset this condition and you would loose
power, you might get better fuel mileage but it might just bite you also

what was the code? Many times the codes last # corresponds to the cyl #.
-
A temp gun works well if one your friends has one
-
Ok I got a temp gun at work. If I swap all injectors do I need a ecm tune!? I did when I put 60 lbs injectors in my big block. I didn't know if the ecu controlled the injectors or not in these motors
-
Can't tune the ECU on these but I sure wish I could!
-
You can "tune" this computer by swapping the sizes of injectors :laugh:
-
guys, i got a buddy has a blown up mitsubishi eclipse...injectors look similar just different connectors. if i splice the conectors could they possibally work?
-
Check the #s for the PPH (pound per hour) or ML per/min
if they are too big you will swim the pistons in gasoline
All of these style of injectors look similar, and can go from 12-15 ish
to 60+ PPH, so I say again Size is what you need to look for and then
you need to make sure they are high Z or high ohm injectors to protect
the EFI computer from injector overload, you can burn the injector drivers
if you use low Z injectors

Ok looks like research is going to be needed. What pound injectors are in the 1.6 motor stock? I can't suppose anything over 20. Small block Chevy's are only 24lbs stock. Ill do some research on the eclipse injectors.
-
I would guestimate the stockers are around 15-17 PPH
-
18lb, 190cc is what I have read for stock 16V injectors.

According to my trust dusty GM Geo Tracker service manual for my '96 the fuel injection system runs between 30-37 PSI at idle. The pump is supposed to put out up to 43 psi max w/ regulator disabled.
If you really want to know exactly what your fuel system is reading I recomend going down to your local GM dealer and ask them to order the fuel rail adaptor tool for you from KentMoore. ???That is the company that they get all their special tools from. The part number for the adaptor that will allow you to put your line end pressure gauge on is J41041. I don't know how much it costs but imagine that it would not be more than the cost of a 18 pack of your fav. frosty ones. :laugh:
You remove the plug bolt from the end under the regulator and screw in the valve and your ready to put the gauge on and know what your pressure is exactly.

Haven't priced many specialty tools, have you? :P

Probably cost you close to $100, by the time you add shipping.
-
Have you checked the colour of the plugs? that should show you if you have a faulty injector or a bad seal.

That won't tell you what the flow rate is.

Well looks like #1 injector is externally leaking now and seems #3 is the injector thats loading up the cyliinder....think i'll get all new ones
-
Well Guess I stand corrected. ??? That drawing didn't look like what was in my service manual but it is current on the pricing in the GM special tools cataloge as well. May just have to tap and adapt for standard fitting. As for the rates you are correct there as well. I guess I have been out of the biz for too long now.
-
Hit your injectors with 12v, if they click then they are working. Do NOT do this with an 8 valve, as you will break the injector. As for the leaking on #1, your o-ring is most likely damaged or slipped off. Autozone has cheap injectors available, or give Hawk Suzuki a call and they can send you some used ones.
-
Guys...question
does the top PLASTIC part of the injector do any kind of seeling? I snagged some escort injectors that are the same except for the plastic barrel at the top above the plug. I'm just going to file it down to match the old ones.
-
It's the rubber O-ring that seals the fuel from leaking, snap a pic and point out
what you are going to file down to make fit
-
pic on the way
-
Its rough looking now but it still need work

-
Looks OK, it's the groove around the top that needs to be good to seal.
Use new O-rings if you have any doubts about the old ones
-
Going to get new O rings now. The O ring channel is bigger on the escort injector...would 2 O rings be safer?
-
The squeeze fit is what is important, 2 o-rings might not squeeze right and leak.
If you have to, just get thicker 0-rings, but the correct inner and outer diameter
to fit the injector and the fuel rail
-
Looks like the escort injectors work. A lot of fileing tho. And double o rings but absolutely no leaks!! Seems a little...less powered but maybe it is me. Been driving the 8.1 silverado all week. I might just be used to that LOL.
-
Those injectors flow 3 PPH less than the OEM injectors
so I bet the power is down a little, but how does it run
overall and how is your fuel mileage after a tank is used?
Those are the questions I am interested in.
I used the Escort injectors but as an add on with the TBI
still in use and a MegaSquirt EFI computer running the additional
injectors

It runs real good now. I don't have to keep it wound so damn tight. I can lug it now but its definitely missing a little power...
-
Oh and no chance to measure mileage yet. Only Drove it about 50 miles so far
