odd code and wont run
Ok guys and girls, I checked as much as possible and got no luck so heres the story.
Got an 89 manual tranny 3.9l v6 4x4 dakota.Recently brand new injector, brand new computer and brand new fuelpump. drives perfect starts on a dime, i hop in and leave work drive about 20 minutes home, i get home take 5-10 minutes leave to go to the gym and it fires right up as usual, two seconds later before i can even look behind to back up it stalls out and the engine light comes on, i have tried multiple times and the thing just does the same thing over and over, it starts up perfect! but stalls out after a second maybe sooner, i tried to give it some gas but it just idles very poorly and sounds like its choking itself out. so i call some people they all give me ideas I come on here to check out what and see the check light codes deal, i go and check it out i get 12, which is true i just got a new computer in it, and 26, I DONT SEE ANY 26 on the list it goes from 25 to 27 any ideas guys or girls? PLEASE HELP!!! I am going form a 2002 trailblazer to this and I regret it already! Thanks in advance

RE: odd code and wont run
code 26 means the Peak injector circuit voltage has not been reached (need to check computer signals, voltage reg, injectors).
During cranking, the computer will test the current through the injector to see whether there's too much resistance in the injector's path. If there is, code 26 is set. The problem may be cured with tuner cleaner on the connectors. For TBI engines, the injector's cold resistance should be between 0.9 and 1.2 ohms (specs vary with year). This is a peak-and-hold injector. With the engine idling the peak period should be about 1.2 milliseconds whereas the hold period will vary. If it's lower than this at idle, then the injector's shorted or there's a defect in the injector driver circuit
