i just picked up a 95 blazer lt. paid less than 1g for it, body is decent, some rust but nothing terrible, has 134k. I just replaced the spider injector cause it would stumble at 2k rpms and up. The new injector fixed that problem. the other main issue I have is it doesnt always like to start. it will crank then catch then stall out immediately, try to start it again it will start up no problem. Im pretty sure it needs a tune up (plugs, wires, cap, rotor, fuel filter) i already changed the oil, air filter and cleaned up the tb and plenum when i had it apart for the injector. short of a tune up any other possible problem places i should look? I have worked on 3 of these trucks before so i know my way around them. (mom has a 98 jimmy, dad has a 01 zr2 s-10 and used to have a 89 s-15) none of them have had this problem that my newest addition is having and the jimmy has 180k and runs like a champ. any ideas?

also what year did they start with drls? previous owner installed keyless entry and remote start (which works half the time due to starting issue) so i want to know if they screwed up something.

the last thing, since its a 95, that means its pre-obdII..or is it? it has the obd2 port and dual o2s but my obd2 reader wont connect with it. unfortunately i do not know anyone with a scanner I want to know because the SES light comes on every now and then.

Thank you!
