1999 GMC Jimmy P1351 code

Im not an expert but ive had similar problems, your sure its an ignition problem.(Spray starting fluid in the throttle) did you check your fuses, or look for loose connections, is there fuel in the fuel tank, make sure none of your ignition compontents are wet if so spray some wd40 on them, is the battery fully charged have you checked or replaced the ignition module, or the distributor itself. Its best to try and test these parts first because, it can get expensive replacing parts you dont need. Then again there is a little piece of mind when change them because your sure that part isnt faulty.
