Hard starting?
i have a 93 gmc that i just traded my 70 c10 for and the thing is hard to start after it warms up,almost like it is flooding but it is a tbi.
i am thinking module or coil but am uncertain. the truck starts fine but runs a little rough. it has a 350 5 spd in it. all i have done to it so far is changed the fuel filter plugs and wires,no i didnt cross em  .but this has me stumped cause i have to crank the heck out of it to get it to start when it gets to operating temps.

I have seen those same symptoms and replaced the module to fix it. See if you can find some one local with a module tester and check it when it's hot. Or pick one up from Snap-On. I don't think they were that bad (price).

just finished up replacing the module,couldnt sleep and took it to an all night parts store here.
module was bad and coil was weak,so i bought both of them. good news its starts better and idles good. bad news is it misses under load and has no power,guess i will be checking for fouled plugs and see what else is going on. may be checking o-2 sensors next and maybe the map sensor as well. could be the cat is plugged,this truck has 215 thousand miles on it and the cat could be plugged.
