OK so i have a 99 chevy blazer with a 4.3 in it. well a couple weeks ago out of the blue the thing just dies. initially we thought it could be the fuel filter, as i was still hearing the fuel pump running, well replaced that and still wouldnt start. my husband gets home from working out of state and he tries to figure out what it is. well thought maybe it wassomething electricals so thought maybe the fuel injector connector replaced that. still nothing. we have pressure and everything. has new spark plugs and wires, and they have spark, replaced the mass air flow censor not to long ago, now we are thinking it might be the spider. reason saying is scanned it about a month or so before this incident and came up with a random miss fire code, cant remember exact code. but ive been reading a few things and think that its one of those injectors are clogged. im just wondering if anyone knows of a good way to clean them? have it all torn out of the manifold and apart, thinking about soaking it down in seafoam, is there any other method that might be better?
