5Toyota Posted January 26, 2019 Share Posted January 26, 2019 My 1988 22re xtra cab truck had become impossible to start below 40 degrees. I found for some reason no more power to the cold start injector. went to napa and bought a replacement plugin . wired it to a toggle switch , a line fuse straight to battery , injector and battery ground . turn switch on at 25 degrees and hit the key she fires right up . turn off switch. and good to go . electric hand choke .

Maineah Posted January 27, 2019 Share Posted January 27, 2019 Comes from a crank signal from the ECM. You may want to be careful of timing they just dump unregulated fuel if forced to inject, lots of it. Quote Link to comment Share on other sites More sharing options...
