have one person in the blazer pumping the brake pedal and then hold to the floor, crack the bleeder then tighten, release pedal, repeat till all air is out one side at a time, if this does not work then your ABS unit is bad witch if u follow your lines from your master cylinder u will find a black box with a motor on it, or the master cylinder itself is bad, it also can cause u to have no pedal, replace the master cylinder first, most likely cheaper.

It can be done but it is very time consuming.
I use an 87 Astro van intake sensors and computer on my 86 OMC.
After six years I am still playing with it.
Runs good and easy on gas.
Got lots of info from DIY-EFI.
You HAVE to change programing in the computer.
I am running a closed loop system with one oxygen sensor in the starboard manifold.
Your 94 computer is not as good for a boat because it also controls the transmission.
Just to give you an idea what your in for.

blank 1 is the connection plugand is on the left side of the motor (purple + black-) and senor 3 is for the o2 sensor which you should have 3 senors on our exhust and the 3rd one is the one on the down pipe (your O2 sensor) replace that that should clear the problem
codes P0131-P0141 all have to due with our O2 sensor
hopefully that helps
I had a 2000 gmc jimmy w/V6 vorvex and m O2 sensor went out 2

You have two knock sensor's, both sit under the in-take magifold on top of the engine, you will have to remove injector rail and in-take.
