96 Voayger no start

[Mechmark]

It has fuel pressure, but no spark and no injector pulse. With snap-on scanner hooked up u can see a rpm signal when cranking. I tried a cam sensor and a crack sensor, neither worked. Any help would be much appreciated.

Which engine?

3.3 sorry about that

If you're not getting coil driver output from the PCM as measured at the coil connector or O2 sensor heater voltage in addition to the lack of fuel injector pulse, it sounds like the ASD circuit is denergized for some reason. You've already checked the most obvious reason, cam/crank sensors. You might try verifying pins aren't pushed and wires are snug on their connectors then wip out your meter and t-shoot the ASD circuit. Are you getting any codes?

As I recall you're getting fuel pressure because the PCM is detecting a crank signal and applying power or a ground path to the fuel pump relay coil. That plus your scanner detection steers the cause away from the crank sensor. That leaves the cam sensor circuit.
