Hey Gurus, I need your help. My 95 blazer cranks but doesn't start unless I spray carb cleaner into it then it will start and run fine all day. Next day I will have to spray it again in order to start it. Any tips would be appriceated. It has a 4.3 vortex auto and 4wheel drive. Thanks for your help.

Fuel pump regulator.


Test your fuel pressure and flow first, might be a fuel pressure regulator, then coil output, spark plugs for excessive gap, also burnt cap or rotor, it may help if you have access to a live data scan tool.


That's what I ment, Duhh. Damn spellcheck. LOL Yes tennisshoes is correct. Check your fuel PRESSURE regulator.
