1998 GMC Sierra Repair Question
Gmc 98 k2500 quit and will not start
30 lbs is no good. you have a bad cylinder.
put your old pcm back, used ones never work.
where did you check for spark??
i check the spark at each spark plug and it's got new coil too
it should start by what you are saying. it is difficult to see if the pcm is grounding the injectors because of the location of the injectors. a shop with a scan tool and verify if they are being triggered to supply fuel.
i know thats what i m thinking what is it wrong with it i check the injectors also have pause so i got scan tool then tell what should i check
there are tests for the injectors that can be performed with the scan tool.
so u mean just hook the scaner and view data while turning the eng over
ck the engine timing.the timing chain maybe bad.
