Magnum swap starts, does not run

From what I gather all 360s and most OBD-IIs have the high pressure. Early motors have the 35psi- but that doesn't mean they all do.

As for security, if anything came with security in '94 that donor'd be it. Can't say they did and that'd be the problem even though that's similar. Definitely need to figure out when you've got half/a third the pressure you need. If everything came from the Jeep but the sensor/flywheel- are the injectors still the same? What pump do you have, and what's the rest of the fuel system like?
