Car wont start right away I have to hold the pedal down to the floor to start it every time

If YOU DON'T HAVE AN AUTOMATIC BLEEDER GET SOMEONE TO HELP YOU. MAKE SURE THERE IS FLUID IN THE RESOVOIR. HAVE YOUR HELPER 'PUMP' THE BRAKE PEDAL NUMEROUS TIMES THEN HOLD THE PEDAL DOWN. STARTING FROM THE FURTHEST WHEEL AWAY FROM THE RESEVOIR OPEN THE BLEED SCREW SLIGHTLY TO LET OUT ALL AIR. CLOSE THE BLEED SCREW AND PUMP UP THE LINE AGAIN HOLDING THE PEDAL DOWN OPEN THE BLEED SCREW AGAIN UNTIL PEDAL GOES TO FLOOR. CLOSE THE BLEED SCREW AND REPEAT UNTIL NO AIR COMES OUT. MOVE TO NEXT WHEEL AND REPEAT. MAKE SURE YOU KEEP THE RESEVOIR FULL.

Try this-- The next time you start the car, hold the pedal down to the floor. If it starts, Then you have a flooding problem. hold it there for 30 seconds. Then while still holding the pedal to the floor, try to start the car. Hard to say on pc. If above does not work, see or call saturn dealer to see if anyone else is having the same problem. Good-Day!

you need a new fuel pressure regulator

hold pedal to floor and it tries to start ! Not sure if your vehicle has clear flood mode , Most vehicle have clear flood mode strategy programmed in the ECU , PCM ,ECM .when you hold the accelerator pedal to the floor the engine computer cuts down on the injector on time to clear a flooded engine .
Fuel pressure regulator problem ,maybe ! You say there was a blown fuel pump fuse an you replaced it ? Fuse's don't blow for no reason ? Fuel pump bad , short , too much current !
Disconnect the mass air flow sensor an see if it starts !

my truck starts right up if I hold the petal to the floor but wont start if I don't hold petal to floor

Good! You bled the master cyl. before installation! The proper order of bleeding the lines, is to start with the wheel the greatest distance from the master cylinder. Then work your way to the next greatest distance, and last, the closest wheel. Make sure all air is removed from the lines before you proceed to the next wheel, and frequently check the master cyl. level, because, as I'm sure you know, if you **** in air at the master, you have to start all over again. I'm assuming you don't have a power bleeder, so with a helper do this with car running (make sure it's on safety stands and not going to fall on you!) Pump pedal 3 times, no need to mash the pedal into the floor, just 3 pumps 1/2 way down, hold 3rd pump at half way down level while bleeder is opened, when flow is about to stop at bleeder, close bleeder and repeat til no evidence of any air. Let me know how it goes and if you need any help.

Sounds like the IAC sensor is bad..Try this when it doesnt start instead of pumping it which wont do anything because its computer controlled hold the gas pedal to the floor.If it start its the idle air control located on the throttle plate..So rememeber the day it doesn't start hold gas pedal to floor and start it.If nothing we have different problems..Let me know and I will guide you through next steps....

The right rear is the furthest point away from the master cylinder and will need to be bled the most. Have another person pump the pedal three times. On the third pump crack the bleed valve open while they keep pressure on the pedal. Close the valve and then they can release the pedal and start the three pumps again. Do this process until no air comes out of the line. Make sure that the reservoir stays full when bleeding so you don't get more air into the system.

1. hold gas pedal to floor while trying to start. do not pump pedal.
2. holding pedal to floor is how you start a flooded f.i. engine

believe it or not, the floormat on my 2000 Sunfire will sometimes slip forward and hold the clutch pedal down against the floor. It truly feels like a mechanical problem, but simply pull the floormat away and the pedal pops right back up!
