1987 Gmc 350 No fuel
Hey guys i have a problem that i need to take care of asap if i can. so here it goes, i have a 87 gmc 2500, 350 fuel injected. so the other day coming back to college my truck started running rough at the end. i got it parked and the idle was super rough. it was late so i left it and came out the next day between classes to mess with it. it fired up the first time with an awful idle. i started playing around and unplugged my map sensor and boom! cleared up my idle. only problem is i shut it off, plugged it back in and no spray. my fuel pump is kicking on and im getting fuel to the back of my throttle body. so is it my map sensor? and i dont have a volt meter on my but will have my hands on one shortly. also the thought of ignition module came across my brain, but it just didnt make sense the way it acted when i played with the map sensor which leads me to think thats what it is.
Thanks guys, im just a poor college student with the love for my pops old truck.
