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.
