My 92 model 22 re when its cold, say under 40 it hard to crank.. It will turn over and hit but not fire on up.. sometimes it takes a while of hitting the starter and realeasing before i get it going .. well about 2 years ago i discovered a little shot of starting fluid and she will pop right off.. I had a guy tell me it was the cold start injector... my question is , How do i know for sure thats the problem? I priced a new 1 at the local Advance and they quoted me just under 200 bucks.. I am a broke poor boy , I kinda need to be sure thats the problem before i drop 2 hundred.....thanks for any help

 

You're in luck. I just did this this afternoon. You're also lucky you live in a warmer climate than me.

First I removed the cold start injector and brought it into the house.

I checked it to make sure it read between 2-4 ohms, it did.

Then I put 12 volts to the terminals and heard a click then checked to see if I could blow through it only with the power on. (should have a small fuse inline and don't leave power to it for very long).

Then went back to truck and hooked it up to the fuel line and the power line but did not install it in the manifold.

I meant to ground the coil but forgot.

I then had someone crank the engine and watched to see if fuel sprayed out the injector. It certainly did.

This should be done when engine is cold. And let it spray into a rag.

If it doesn't spray either it isn't getting fuel or the injector is not getting a signal to open. If the engine is not cold it probably won't spray.
