My truck has been experiencing a problem with starting over the last month or so. It would have a hard time starting when it was cold out. It didn't start, then I jumped it and it started up. A coupel days later same thing happened. So I checked the battery, it was no good. I got a new battery and everything was great. Then a couple a days when it got cold again I noticed it had a hard time starting again. Then didn't start. It cranks fine but wont fire. I jumped it, and it started. Then went out in the morning and it wouldn't start again. Now it wont start even after a jump.
A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech
