Questions and Answers

Ford Crown Victoria No Start

Q. I have a 1997 Ford Crown Victoria, 4.6 liter, 120,000 miles with a no start problem. The engine will turn over but I do not get a fire. I have listened for the fuel pump to come on and it does. I have sprayed starting fluid into the intake and still no start. The car has two coil packs in it.

I have checked the resistance on the primary and the secondary and they read okay (I verified this with another Ford vehicle). When I turn the car over (using a spark tester) I don't get a spark at all (putting it into a spark plug wire) The other Ford gets a good "glowing" spark. The voltage coming into the coil looks okay, about 11.8 - 11.9 v. Both of the coils read the same.

Looks to be something common between them so I went back to the ignition module. Actually I can't seem to find it. It is not where it is supposed to be. Driver side, fender or firewall mounted. I pulled a module over there (it has two large gears under it, a spark control module perhaps????) So I guess that is where I am stumped. Is it located somewhere else or integrated into some other module?

I have been to several part stores, showing them this "unusual module" and looking at what a ignition module looks like and I can't find one on my car that looks like that. Please help!!

Thanks in advance!

A. Your car does not have an ignition module per se. It is part of the Powertrain Control Module (PCM).

What you might try is this, connect a fairly heavy jumper wire from the engine block to the negative battery terminal and see if it will start. There has been a bit of a problem with the engine block grounds. If it starts, you can repair the existing ground wire or add a second ground wire. I would recommend both as a back up.

If this doesn't work, I would recommend having the codes pulled from the computer and see what they are before replacing the PCM..
