s10 Blazer only starts when cold
Hi my name is Derek. I have a 93 s10 blazer 4x4 4.3 cpi. I am having trouble with starting the vehicle when it is hot. If I try to start it when it is hot it will turnover for at least 20 to 30 seconds before it will try to start, if at all. When I do eventually get it started it run decient. I have checked the fuel pressure. I have also changed the spider fuel injection unit under the upper intake, cap and rotor button, coil, pickup, Ignition control module, sparkplugs, wires, and checked the fuel filter. It will start everytime in the morning like clockwork. I do hear the fuelpump running as well. If anyone has had a simmilar experience please help me. I am at my wits end. Thanks Derek

Re: s10 Blazer only starts when cold
are you sure you put the dist back on number 1 after you replaced pickup coil in it? i would check that first and make sure it is on nuber 1. i have a 91 and i had to buy a new distributer for mine it had a hair line crack in it.
