96 mpi mefi 1 no fuel pump or beep
 

96 mpi 502 mefi 1, i have power to ecm no fuel pump or beep when turn key... Any suggestions?

Fuses OK?

Wiring to fuel pump ok?

Fuses good, wiring good, 12v to ECM nothing after, no voltage green white wire to pump. No beep when ignition is powers on

Not sure about 1996 but on 1998+ there's a fuel pump relay located near the ECM that you should check out.

Dumb question.......but is your gear shifter perfectly in Neutral?

If the neutral safety switch is tripped a bit it makes the engine appear dead, non-responsive, no crank. I've been guilty of this....even to point where I get pissed and start checking fuses, relays, etc. only to find out the shifter was bumped against the switch. I have a habit of jiggling/re-centering the shift sticks every time before starting now. With my old boat that had aftermarket ECU, I got used to not worrying about it because switch was disabled, when I went back to Merc/MEFI ecu's on new boat, sure enough the neutral safety switch pissed me off at the launch ramp when one motor wouldn't fire and acted completely dead.....

Shifter appears to be in nuetral, engine does crank, however no beep when key turned on and no fuel pump run to prime, traced power to ecm nothing on other side

On a tangent to what Gimme Fuel referenced check the lanyard kill switch too.

Yes the plastic forks on the kill switch lanyard get weak and while it looks like it engaged it is not fully engaged. Try holding the button in a different see if that makes a difference.

No power on either side of what ? What wires did you test to determine this ?

Edit in: don't need to answer above. I get it. Read what you said wrong.

If anyone wants to look at the wiring chart, look at Pg 42 of this .pdf:
