My 1996 crown vic will not start motos turns over and trys to start but wont I have replaced intake manifold spark pulgs. motor has spark

Believe that is the thermostat housing , if so yes

Try checking engine fuse. I had a car that was down for a month. I couldn't figure out why it wouldn't crank. I finally started checking fuses and my engine fused was blown. It is worth a try.

3 things keep a motor from starting.1. NO SPARK, 2. NO FUEL,. 3 ENGINE DAMAGE. I SUSPECT IT IS THE IGN MODULE WHICH IS INSIDE THE DISTRIBUTER. cHECK TO SEE IF IT HAS SPARK.. iF IT DOES THE IGN MODULE IS NOT THE PROBLEM. iF IT DOES HAVE SPARK CHECK TO SEE IF IT IS PUMPING FUEL.. DO THIS BY SQUIRTING A LITTLE FUEL INTO THE INTAKE MANIFOLD THROUGH THE INTAKE AIR HOSE RIGHT BEFORE IT CONNECTS WITH THE INTAKE MANIFOLD. .. iF THE MOTOR FIRES AND TRYS TO RUN YOU KNOW FUEL IS THE PROBLEM. IN WHICH CASE IT COULD BE A CLOGGED FUEL FILTER OR A INOPERTIVE FUEL PUMP. iF IT HAS FUEL AND SPARK LOOK FOR A BROKEN OR STRIPPED CAM TIMING BELT. NOT TURNING THE CAM OR CAMS.

I have faced the same thing with my car, this is not a single answer to this problem. It could be a bad boot on the coil pack, it could be a improper coil install, sometimes the spring does not sit in well, it could be that the intake manifold is leaking, it could be that the egr valve is stuck, it could the exhaust manifold is leaking, sometimes these issues are not caught by the OBD 2 sensors, you can try to move the coils around to see if that works out.

Cylinder misfire on #7.could be bad spark plug,or bad coil.try replacing coil and plug at# 7. It is the second last plug on the driver's side. If you pull the coil out and there is antifreeze in the spark plug hole,you may have a bad intake gasket or cracked intake manifold and the antifreeze is shorting the coil out. In that case you may have to replace the intake manifold.

first check if there is fuel coming through then check your nock sensor which is on the crank pully then *** back 2 me

Intake manifold clogged or blocked off?

water in oil pan? try taking out the spark plugs and turning car over. Is there coolant/water coming out? If so you need Head gaskets or intake gaskets weren't done properly. If this problem wasn't there before gaskets were done I'ld strongly suggest looking at intake gaskets again.

Yes the manifold is plastic and you need to repair quickly or you will have alot of water in your motor and bye bye motor or car
