My 96 crown vic police interceptor, cranks won't start without spraying starter fluid.. the car won't start without spraying starter fluid into air intake hose to carb...

That is a transmission code...

P1747 (EPC Shift Solenoid). Not uncommon for police interceptors...

Here is a discussion of other possible causes:

did u check ur passin gear cable

When the alternator goes bad, it can start doing that, and eventually will stop working. If the ground was not tight the starter wouldn't work

They had a couple different alternators for that car,basically the same alternator but different regulators,might be where your trouble lies

The PCM is programed for the LS engine parameters and now that you have changed engines the signal from the new engine are out of parameters> Either see if you can get the PCM reprogrammed at a dealership or purchase a new PCM and program the chip with the police engine interceptor to the vehicle> you may also return to the place where you got the engine and purchase the PCM for the police vehicle.

• Yea, you can test it. Put your multi-mater to Ohms and put the leads on the sensor. You should have around 700-900 Ohms and this is good.
• test the output Voltage of the sensor by putting your mater on Voltage AC and (with the leads on the same way) Now crank the engine over (it won't start because the sensor is disconnected) and look for a reading over 200mV

• That's how your test your Crankshaft Position Sensor.

• If you have any comments please feel free to leave them here.

Check all your grounds and make sure all starter wires are tight and clean..

you can get a A/C Delete kit for a Ford 4.6 liter. the 4.6 v-8 accessory drive system is all the same. You may also be able to run a line of string around the pullys, take it to your local auto parts store and they can match it up. I recomend the kit,

i have ran into 2 issues in these vehicles---if it binds while sitting still also, check the steering shaft, i have found the u-joints in the shaft tighten up and binds dangerously tight---if they are free, sounds like you may have a steering box issue or restriction in a line---hope this was helpful!!

Have you checked the fuel filter. Fuel pump will pressure up, but fuel filter could be clogged and not work without the pressure of the fuel pump.
