My Fuel pressure is at 13 when I turn the key and just replaced the fuel pump? The fuel pump is from rockauto so it's GM certified. It won't turn over! Suggestions
Do you
have the same problem?
Yes

FUEL DELIVERY HAS NOTHING TO DO WITH "TURNING OVER" ALSO KNOWN AS "CRANKING" (WHICH MEANS THE STARTER IS MAKING THE CRANKSHAFT ROTATE)

"START" / FIRING UP/ BUSTING OFF/ RUN/ ETC. MEANS THE ENGINE IS NOW USING COMBUSTION (IGNITION AND FUEL) TO TURN THE CRANKSHAFT

YOUR FUEL PRESSURE SHOULD BE NO LESS THAN 50 PSI

EVEN A NEW "ANYTHING" COULD BE BAD, WHETHER FROM ROCKAUTO OR SANTA!

(JUST ONE OF THEM THINGS YOU MUST ALWAYS KEEP IN MIND ON ANY REPAIR-CAUSE YOU WOULD NEVER SUSPECT IT, TILL THE ENTIRE VEHICLE HAS BEEN TAKEN APART!)

OTHER THINGS- CRIMPED LINES-*******BAD FUEL REGULATOR*******-INSTALLED WRONG-GOT GAS?-NOT TESTING CORRECTLY-ETC.

SHOULD YOU NEED SOMETHING (NOW OR LATER) THIS MIGHT, IN SOME WAY, HELP YOU OUT. "A124" WAS STILL WORKING A FEW DAYS AGO.

LET ME KNOW IF THIS IS SIMPLY "THE ENGINE DOES NOTHING AT ALL, WHEN YOU TURN THE KEY TO "START"
