Help! 450 DSM injectors not firing?
Yesturday, I decided to install some 450cc DSM injectors and a map hack circuit so I can run them on my 89 civic si. I took out the old stocks and put in the DSM's and the circuit on the map. Tried to start, no start just cranking from the starter. I took off the map hack circuit, no start still just cranking.
I then tried troubleshooting. Look to see if I was holding fuel pressure, fuel pressure was holding. I know it is not spark, because I didn't touch any ignition components. Pulled a plug to see if it got wet from fuel, it was bone dry. Tried to smell for fuel in the hole, didn't smell any fuel at all in the hole.
Now, the only thing I can think of is the injectors not firing. I hope I didn't get scamed and bought 4 bad injectors. How can I test an injector? TIA

First, make sure you're getting juice to the injectors by using a Noid Light plugged into the injector harness. 2nd, you can check injectors to see if they work by hooking a 9V battery up to them. Gently hold the injector and connect the 9V battery and feel for a small jerk or click. If you don't feel that, bad injectors.

I know I should be having power to the injectors, because I hooked my stocks back up after this and it worked like usual and cranked the first time.
I have a resistor pack because my car came with it stock.

Update:
Did the 9v battery test and they did not click at all, but current did flow through according to my test light. I tried a stock injector for referrence and it DID click. Am I missing anything with these 450's or do they just plain don't work.
I got them off of someone on the board with the screen name racerxadam. Can anyone vouch for this guy?

I offered to refund your money, but I want the injectors back. They worked in a friends car before removing them. I don't want to be labeled as a bad seller on this board and I am offering to do anything to make the situation right but I'm not going to get taken advantage of by refunding without return of the product.

Re: Help! 450 DSM injectors not firing? (racerxadam)
I just want someone to vouch for you so I can trust that sending them back will get my money back. I'm not calling you a scammer, but I want to know that you are legit and if you did have any history of bad sales or not.
Again, I'm not calling nor have I called you a scammer, just trying to see if anyone will vouch for you. I'm probably gonna return them even without a vouch, but it's good to know if a guy is straight up before shelling out for shipping.
I sent you money first before I got the product, so why can't you do the same? But to end any arguments that might arrise from this, I will send them back to you and you can send me my money afterwards. After all, you did send them right after you got my money, but just unfortunatly they didn't work.
I am in no way trying to disrespect your honesty, but hey.... they don't work. I'll even vouch for you being a good seller after I get the money back.

I can vouch for Adam as well. He has helped me tremendously with tuning my car and doing other odds and ends. He lives very local to me, about 10 minutes away. He can be trusted....hell I let him help tune my car!!!
I think you might be having problems wiring them up.

Re: Help! 450 DSM injectors not firing? (93LSivic)
How should I wire these injectors up in an 89 civic si? I thought you just put them in and they should work. They fit in the injector plugs just fine.
I tested them last night again, but I sprayed some carb cleaner down them and now they make a very slight click when I test them, but my stock injector clicks 10X louder than it. I also tried blowing air out it while testing, but no air could come out, but when I did this with my stock injector, air came out.
Maybe I need more power to the injectors? Should I try a 12V source from my car and hook it up to see if that works? Is there any tricks on making it work in a car that came with a resistor box?
I guess Adam is a straight up guy, he is willing to take it back and send me the money when he recieves the tracking #.
I will try my best to see if the injectors will work, maybe they stuck some how.
