Your blazer has to have 55 psi or better to start and starting fluild is possible to flood the plugs now their too wet to fire. Sit awhile and they should dry on thier own. The injectores won't past fuel below about 40 PSI while cranking the voltage to the pump or the pump ground is going away (starters not grounded good enought and the ground goes positive as the car cranks. Put jumper cables from another running car and coonect them right at the starter ( at least the ground, connect it right o the case of the starter, Pos/ can be connected at the battery). sure your battery may be toast and still crank a good starter but the voltage below 10 while cranking may not close the fuel pump relay al or the ingtion module. I've had this problem and sometimes I've found the ingtion module bad and I had it tested at the store and they said it was good but as I sent it in to be tested they sent a new one anyway and the new module would run it and the tested good old one won't start the car. BUT. Everytime it goes back to the quaily of the fuel pump and I've bought a lot of bad ones for GM products that were made by Master and Airtex. I've never had a problem with a Delphi. As long as the crank voltage is good jump it to make sure and the pump wire while cranking is more than 11 volts and it still has less than 55 PSI you take the pump back get another one or demand the delphi, and if they want you to put in another aixtex ask them to pay you to put it in. Bet you'll get the Delphi. The return level is high on the Airtex and Master pumps is high and the parts guy your buying from knowns this unless he's still wet behind the ears, and plain just does'nt know. Orginal equipment in this area keeps the comebacks away and I'm a pro. unless the customer makes me put in the junk pump I don't even give them a choice.

The plenum shouldn't be damp with gas. Is it a throttle body fuel injection system?

Could be a leaky injector.

2002 yukon wont start drove it allday yesterday and last night .woke up headed to to work wouldn't start tried jumping it still kno start replace battery and still wont start


Is the starter engaging when you jump start it? You say you replaced the battery, is the cable ends clean? If the starter is engaging you have other problems, if its not then check out the starter/cables. Good luck!

Ran fine last night drove round trip prob 75 miles no prob parked tried to start in morming keepd cranking wont start less than 1/4 tqnk off gas banged on gas tank while cranking still wont start any...


One way to check the fuel pump is to turn the ignition to on and listen for the pump to run. It should run for a few seconds. It may be a couple of seconds after you turn the ignition to on before it runs. Normally you can do this repeated times.

If you don't hear the pump run that is most probably the problem.

Water?


The Cap and wires are most likely still wet (must have been a really large puddle). You can open the hood and try to air dry them or get a can of starting fluid and spray the cap and wires to dispel the water. Let the fluid evaporate and try to start the car. Best of luck.

Sounds like a bad ground.Check for broken connections or corroded terminals especially around the battery as acid tends to seep from them and corrode the connections.
