Will a 1993 mercury engine fit in a 2002 grand marquis


Without seeing the two, I would say no.
You would have to check motor mounts, bell housing, exhaust pipes, and then all of the emission components and wiring to find out.
Even the radiator hose outlets.
A salvage yard should have an interchange book to help tell you.

2003 grand marquis with misfire code p0316


The first problem you have is assuming that the ignition coil is the only thing that can cause a misfire.

Diagnostic Test Code (DTC) P0316 is a "continuous memory only" code that indicates that there is a fault causing a misfire during the first 1000 revolutions of the crankshaft immediately after engine start-up. This should be accompanied by the regular cylinder misfire monitors (Codes P0301 through P0310) unless the misfire does not continue long enough for the regular misfire monitors to determine which cylinder is misfiring.

In order to determine what is actually causing the problem, you must have access to a scan tool that can perform Key On Engine Off (KOEO) fault testing and Key On Engine Running (KOER) fault testing as well as interfacing with the onboard engine computer to read live data and perform system tests.

Please note that generic OBD code readers DO NOT have the capabilities to do what you need to diagnose this problem. You will most likely get additional DTCs that can help lead you to find the source of the problem when KOEO and KOER tests are run. Generic OBD code readers can access only continuous memory DTCs.

Possibilities/conditions/systems that can cause this code are:
>Camshaft Position Sensor
>Low fuel: less than 1/8 tank
>Stuck open EGR Valve
>Blocked EGR passages
>Ignition system
>Fuel Injectors
>Fuel injector control circuits
>Running out of fuel
>EVAP canister purge valve
>Fuel Pressure
>Evaporative emissions system
>Base engine (mechanical) problems

Trying to put a new vapor canister in 95 grand Marquis.I got two lines running from engine to plug into canister but my connection has two plugs for my lines but on canister still a open hole nothing to...


Section 03-13: Evaporative Emissions 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DESCRIPTION AND OPERATION Evaporative Emission Canister Fuel vapor emitted through the evaporative emission valve (9B593) is stored in two evaporative emissions canisters (EVAP canister) (9D653) . I think you should have 2 engine vacuum lines, one for each canister.

---------------------------------------------------------------
Evaporative Emission Tube Shut Off Valve The evaporative emission tube shut off valve (9G332) is located in-line between the evaporative emission valve (9B593) and the evaporative emissions canister (EVAP canister) (9D653) . The evaporative emission tube shut off valve control valve is mounted on the fuel tank (9002) by an integral bracket. The evaporative emission tube shut off valve closes the flow path from the evaporative emission valve to the evaporative emissions canister during refueling to prevent overfilling of the fuel tank .
