I am using a '97 Crown Vic as an enduro race car. The car must be stock, but gutted inside. While stripping the interior, I believe I have cut a wire to a sensor and now the car will not start. I drove it to the shop I'm working in and can't figure out why the car won't start. I have bypassed the fuel shut off switch, but it still won't start. What am I missing?

Yes. You need the ecu that came with that engine. Did you switch intakes? The f 150 4.6 has a taller intake and I believe the stroke is different. I would switch the throttle position sensor too.

lots of these fasteners the car manufacturers use are pretty cheap..sometimes I use a special 90* set of wirecutters to cut through certain fasteners..they are like a pair of pliers but with a wirecutting head on them..sort of like a mini bolt cutter..in severe cases I have actually use an angle grinder to cut through it or a sawsall..depending on the room to work..which is usually very small..it may require two people for removal as one needs to be inside and one outside..sorry I wasnt much help here..

HOW BROKE IN A 1998 CROWN VIC TRUNK

I know I have taken the fuel line off of cars to pump fuel out of tank and it only pumps soon as you turn key on for a couple seconds. And while your cranking it. But keeps pumping while it is running, I think it is the relay that keeps it running. Not positive. Did you hook it up the same as it was? How about the fuel pump cuttoff switch? If you hooked it up to part of the system, like the ignition, but it isnt connected to the computer through another wire that turns the relay on while it is running, then that may be it? Just trying to help. But I know if your racing You should have some sort of cuttoff on it just in case some hatter slams you into the wall and blow up. lol Good luck and have fun

When they removed their wig wag and siren from my car, they cut the c.r. ap out of the wires. What a mess! Took a piece of wire (with both ends stripped) to test with... stripped a small area on each wire, and touched the test wire to the bare spot and the battery, until the horn sounded... that is the wire we used. Then, using a push button bought at Auto Zone ran a doubled wire inside the cab, cut it and placed one end on each side of the button... under the hood, one end of the new wire connects to the one that made the horn sound, and the other end of the new wire connects to the battery. Use electrical tape to cover every wire that was shaved, the ones used AND the ones not used. NOT PRETTY... but we have a horn.

Check the transmission linkage cable that runs from the steering column under the dash to the trans under the car. make sure that the cable is not damaged and that all connections are tight.

Sounds as though you may have done some serious damage to your wring harness,try splicing the wires you cut back together if you know which is which. This may solve it or you may need a new wiring harness, tou may be able to find one from a salvage yard. Good Luck To You

Make sure you are using a 12volt DC system in both units. It may sound simply but an AC sub may need an inverter. Also check grounds.

I believe once you have mounted the horn and connected the wire you will find that the horn wire was cut at (by) the steering coloum that the siren override was hooked to,you will have reconnect this,I hope this helps you

These things were replaced on my Crown Vic: The crankshaft sensor and the DPFE(?) sensor; the main cause of the missing, cutting out, etc., however, was due to the fact that the #8 coil had gone bad and was fouling the spark plug. I had to take my car to the dealership before the problem with the coil was discovered. They also cleaned my fuel injectors, but I believe the main problem was the coil and the spark plug. Let me know if this helps!! Good luck!
