Hey guys so this is my first post here and hope i can get some help. my 87 gmc's injectors are not spraying. first off it started with a severe rough idle. i shut it off when i got down to school (college student without a shop here) and when i went to start working on it it ran very rich. i mean those puppies were spraying the fuel. so i started playing with things (unplugging and plugging back in) when i did this to the map sensor my idle cleared up briefly. im getting fuel through the lines now to the back of the throttle body but nothing through the injectors. what i gather is the map sensor or ignition module? i dont have my volt meter with me or i would do some better checking but is that what we would all agree on?
