496 ho wont start has spark has 43 fuel pressure, turn the key on get 3 beeps it for a friend of mine thanks

I would guess a crank sensor. A couple of the main sensors have to have 5 amps to allow the motor to fire. Check all connections.

Might sound stupid. make sure safety key is attached and that you have a fully charged battery.

Haha....we've all done it!

same here and couldnt figure it out. The kill switch was slowly corroding, we would be running hard then all of a sudden die. Tow home and it would start on the hose

Does the motor turn over and just not fire or just do nothing?

engine sensors get 5v reference not amps!
