SOURCE: 1999 Chevy S10 cranks but wont start

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

, do a simple test on the charging system...check battery voltage. should be 12v or better. start engine & check volts at idle, no accessories on. volts should read 13.5 -14v. Turn on all accessories(including headlamps on high) volts should drop slightly but should not creep down. Definitely not below 12.5. If voltage drops lower than 12.5, the regulator (in the alternator) is not working. either change regulator or change entire alternator. Alternator drive belt should have sufficient tension so that alternator cannot be turned easily by hand. If it can, check belt tensioner.

Possible not shimmed correctly. The starter teeth have to engage correctly for the starter not to hang up. That's what probably happened & broke teeth off. You had better check your flywheel around the entire circumfrence as teeth may be missing from it as well. Starter won't engage if teeth and flywheel teeth in same spot are broken off. If the flywheel teeth are bad, it will be a spendy fix to put a new one on... Rick

Sorry to say its your head gaskets. Probably from the overheating it wore out the gaskets. that milky stuff is your coolant mixing with your oil. Good luck. Suggest you take it to a pro. the gaskets are easy to change, it's everything else in the way to get to them that requires special tools and experience. Let me know how it goes. I have the same thing with my truck but not real bad. If your truck is running smooth and doesn't feel like its missing, or when your start it no puff of white smoke comes out your exhaust it's not that big of problem. if these are happening then i would get a quote.

can you turn the engine by puting a wrench on the harmonic balencer? if not then the engine is locked up!!! if you can turn it this way then check your battery conections and body grounds!!
