cold start problem
So i live in fairbanks and its cold well now its 9*F. I didn't have the truck plugged in to warm the block. I have just fixed all the problems and now this popped up like a zit before prom. The truck wouldn't start so I guessing its the cold start injector or the coolant temp sensor. I don't want to drop any more money down since this week I have spent a lot for a college student, its around 500$ this week on parts. My question is that would a coolant sensor cause this problem since its not telling the ecm to use the cold start injector?

Could be a sensor.
Pull the CSI off and crank it. If fuel comes out you'll know that system is working ok.
Oh and careful. Gas ignites like crazy.

After you make sure your CSI works you can try pulling out the cold start sensor, and the coolant temp sensor and clean em up. Remember to plug the threaded holes that they come out of as coolant may spill out. Do this with the engine cool/cold. if there is any scales of calcium or such on there that is what could be causing your difficult cold starts.
Mine used to have a problem with that since I cleaned them and also upgraded to a non-jerry wired O2 sensor.

9*? Must have been in the morning. I just went to the SRC and the University sign said it was 29*!!!
If the coolant temp sensor isn't reading the temperature of the coolant, then yeah the CSI won't squirt. clean it all and make sure the wires arent shorted or anything.

Guys.......coolant temp sensor isn't related to the cold start system. Just the timing switch for the cold start injector.
Run a wire from the cold start timing switch connector........ground side, not sure which, either one of the two terminals.... to the battery ground. See if that helps. This bypasses the timing switch, if it's going bad. If it is going bad, you won't get fuel from the cold start injector.

I ran the - from the cold start timing switch wire harness to the - battery terminal. Since i didn't have a long wire i used my uhms tester wires and connected them with a smaller wire.

Hmm.......well, if you're sure the wire has good continuity the way you rigged it, then I'd would suspect your cold start injector or the wiring to it. Buggers.
