97 blazer wont start again replaced many...
this 97 blazer gives so much trouble it has a new ignition switch new fuel pump 2 new batteries 2 new alternators. now it wont start again it turns but wont catch. tried to check the oil pressure switch. dont know where that is. supposedly the oil pressure switch turns off fuel pump if the oil pressure is not right. we seem to be losing power that keeps draining different things. any ideas? also where is the oil pressure switch?

the oil pressure switch will not kill the engine it will allow 12v to the fuel pump once switched closed by oil pressure if the fuel pump relay fails.
It acts as kind of a fail safe if the fuel pump relay fails. |
