    Wont start -Help please

    Long time lurker, first time poster.

    Any ways, I have an 1985 ford crown vic and it wont start.
    Heres what happend: I had to drive to wendys to do something and my car started fine and drove there just fine. I got there and went inside for only about 5 minutes and went back to my car to leave and I turn the key and give it a little gas to start it and it starts but then it bogged down and died. I changed the fuel filter in the parking lot and that didnt help. Now it will just crank and crank but wont fire.

    I go to a vo-tech for auto mechanics so we had it towed there so I could work on it. It gets gas, so we figured its not getting enough spark. So I went out and got new plugs, wires and a cap and rotor.

    Do you think this will get it to start?

    Any help is appreciated, thanks

    I'm betting the TFI module, the grey thing on the side of the distributor, died on you. If you have no spark at the coil, I'd lay money on the TFI being the problem.

      Sounds like that might be it. Also, this happened to me, I disconnected a wiring harness (The rectangular harness), for my alternator when it caught on fire. It was the one with just one wire. A jumper wire really. Anyway, this completed a circuit that allowed the car to start. I would have to say it's the TFI module, but it doesn't hurt to see if any wire harnesses came loose or disconnected. I hope this info and anyone else's helps you determine your problem.

        if it doesent have spark replace the tfi module (ignition module)

            Checked it and it gets spark. It also gets fuel, and we checked the comprssion and they were all between about 90-105 psi.

            Any other ideas?

              compression is pretty low, you should see 120 or better, 150 being more in the OK range. 100 psi is like lawnmower compression levels. Fuel, fire, and compression and you should be good to go. Are the plugs fouled out or wet or anything? Can you see the injectors misting fuel? The connectors at the CFI units have been known to break before, there is an electrical plug there that must be plugged in and making contact or the injectors won't fire.

                The plugs are fine, I put in new ones and we had to pull them out a few times and they were all right. Yes I can see the injectors spraying fuel. All the connectors under the hood seem to be ok.
                I also thought that even with low compression it would aleast fire a couple times.

                  Have you stuck a timing light on it while cranking to see if its anywhere close? I wonder if maybe you had the timing chain jump.. The older cars used plastic coating on the gears, and it would chunk off and the timing chains would get real sloppy.

                      Like they said, if it has fuel and spark (enough of both) it should light off. If not, then it may be a timing problem. Either a timing chain or something bent or broken. My money is on the timing chain if the static timing is off.

                              Well right now its in the votech.

                              Anyways, Today we checked the fuel pressure with a fuel pressure gauge, and it had none. But when i first brought it seemed to have pressure because we unscrewed the plastic cap thats on the tb and pressed it in and it sprayed out fuel.

                              But we also poured some gas into the tb while cranking it and it did nothing.

                              Do you think its the Fuel pump?
