Injectors working?
 

How would you know if your injectors are working. Is there a way to check the injectors with an ohm meter or check the ecu to see if there are pulses coming from the ecu?

Noid light like I posted in your other thread. Ask your auto parts store for one...should have them with the test equipment.

Re: Injectors working?
 

You could always unplug the injectors one at a time while the engine is idling. You'll be able to tell when one isn't working.

thats the problem. The car doesn't run.

Re: Injectors working?
 

Dose the car have spark? If it dose then shoot some starting fluid in the bitch and fire it up.

Re: Injectors working?
 

thats what I did and it still didn't start for some reason. I can just go down the road and spray staring fluid in there. I'll need to buy it in bulk.

Re: Injectors working?
 

After trying to start it are your spark plugs wet? When you key the car to the run position do you hear the fuel pump prime? Pull a plug wire off and stick a spark plug in it and have someone turn it over to see if you have spark. Need spark air and fuel to run, if you dont have that it wont start, but you arnt a noob so I shouldnt have to say that.

Yeah I am no noob. I have checked my spark, fuel, and just about everything I could think of. I think that it is either my grounds are bad or my ecu is done. I am getting another ecu to try it out. It started once but then died. I think what happened was when I wired my injectors for the obd1 injectors they didn't like it and fried my ecu. But the first time I cranked it it spit some fuel in there, started, and then fried and died right after. So it did run for like 2-3 seconds. So I know it will run. I have put some obd0 injectors in it since and tried that but no luck yet. I did pull out the brand new plugs I put in there and I smelled very little of anything. I think that it was just the old oil that was on the treads of the plugs.

first off , what is ur car? is it all stock? are u runing with satured or P&H injectors? ecu chipped? let us to know more about ur car

Re: Injectors working?
 

Its all back to stock Si but with a d15b7 engine. I put the Si injectors back in there and everything. Who knows.

Re: Injectors working?
 

How are you checking for fuel? My fuel pump sounded like it was priming at one point, but ended up needing replaced. Also, if you are running a resistor box, double check your wiring, and make sure the resistance is right

Re: Injectors working?
 

Well I pulled out the spark plugs and I could smell fuel plus I have a Fancy B&M fuel pressure gauge on my fuel filter. What should the resistance be on the resistor pack?

Re: Injectors working?
 

i guess he means check resistor box is right conectec

Re: Injectors working?
 

Car runs now. It had nothing to do with anything other than the cylinders were dry.

Re: Injectors working?
 

disconnect your starter and crank the motor over, you should hear them make light clicking noises, and if you can't then hold a screwdriver up to them and put your ear on the screwdriver ;)

Re: Injectors working?
 

As I said before it runs but thats a cool idea with the started disconnected. Never done that before but I have used the screwdriver to listen for ticks and noises. Works well. What I ment that the cylinders were dry was the engine sat for such a long time the oil that helps seal the rings washed out and had no compression when cranking over. I had to pour oil in the spark plug holes and crank it over till it started. It took a good 3-4 cap fulls to make it work but it worked. Car runs good now.
