No power to the coil pack. Replaced computer, same problem. Which wires do I check on the input side of the computer for power and where would I find the source of the problem if I have no voltage?

    According to the manual I should get a indication of power to the coil connector when hooked up to the positive side of the battery and the red, white or black wires. This is with an assistant cranking the engine. I have also replaced the camshaft and crankshaft position sensors.

    I have checked the feed from the computer multiplug connector to the coil connetor. It shows continuity. I think that the computer is not getting any power. I have no check engine light to check for problems.(light does come on when key is on, then goes out.

    I have checked the asr and fuel pump relay, they check out. All fuses have been checked, I have also checked out the fuel pump, it is operating and I get about 50 psi. avid101 has mentioed a firing plate. It seems that it contains diodes. One person thought I was talking about the intake manifold - no. I have also checked out the resistance on the coil pack, it checks out.I get no trouble codes using the key method. I would like to know which wire to check for power on the input side of the computer. I have also replaced the camshaft and crankshaft position sensors. Any Ideas?

Check your Auto shut down relay (ASR). it may be bad or there is a problem with your fuel pump, ignition coils, or ECM. The auto shut down relay will have a close loop when there is no problem detected, when the ignition is turned off the auto shut down relay will have a open loop killing the the power to the ignition coils, fuel pump and ECM i believe to keep the engine from running. If there is a problem with the fuel pump like a bad wire or bad fuse, the relay will go in a open loop killing the rest of the other functions like the coil and ECM also. Check the fuse and look for any corrosion that may have triggered the auto shut down relay, check to see if you can pull any DTC codes by turning the ignition on and off 5 times and counting the check engine light to see if it may be a bad cam shaft sensor or crank shaft sensor which the ECM will trigger the ASR. Good luck and hope this helps. The ASR should be in the fuse/relay box by the battery under the hood, you may want to swap the relay with another one there to see if it's is the relay and if you have a multi tester, check to see if your have power to the terminals to the relay slots and check all the fuses.

    The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module.  This causes the engine to shut down. 


    The logic module monitors the relay driver.  If it senses that the relay driver is not responding correctly it will trigger a code. If the logic module does not sense an absence of current when the circuit is open, or 12 volts DC when the circuit is closed, it knows that the circuit is open or shorted, and triggers code 42.  In later models which used the SMEC or SBEC, the logic module monitors the output of the fuel pump relay output as well as the fuel injectors.  If it does not see 12 volts DC when the relay is activated, it triggers code 42.



    Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. “The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.” 


    There is also an engine fuse which might have blown - along with various fusible links. Check the owner’s manual to find their location. Note a common problem: when no electricity was at either coil terminal with the key in ON, but the engine still cranked: "repair the burnt-out fuse able link in the wiring harness next to the left shock tower."


    Another common problem is the Hall effect sensor, which tells the computer where the engine is. This is moderately easy and inexpensive to replace (as is the MAP sensor.) Even cars with no distributor use Hall Effect sensors, on the block.  

    Good luck and one of these things will help lead us into getting the car to run again, bear with me. I just drove back form Chicago on a tour bus. Keep me posted, be glad to help get your car running again.

Did you replce the firing plate? it has diodes in it and that can cause it not to fire.

Hi,

Hi
I don´t see why it should have taken all day !

Yes, this sounds,..... if true? that the problem is in the wiring to the coil pack. ( Faulty coil packs are the most common problem ! )

The next multiplg on the loom, from the coil pack feed, should be disconnected and inspected, and checked for feed, and so on.

Might be worthwhile swapping over 2 coil packs, just to confirm there diagnosis was correct.
If they were not..... the misfire will change cylinders.

Hope this has been of help to you.

Good Luck !

    Thanks for your response!!

    You car probably have a bad module. The best thing would be to take the
    incorrect module back and get the correct one. I have seen modules go
    bad where one of the coil packs would not fire.

    Let me know once checked so that we may proceed.

    Thanks.

Don't dismiss the coil pack completely. The hi voltage side of the pack is what usually fails.

Coil quit firing


If you have no spark from two of the four towers of your coil pack, you need to check the wiring between the coil pack and the ignition module. Since you have spark at two towers, that proves you have power to the coil pack. Both sets of coil windings in the coil pack are fed by the same B+ feed,(red and light green wires to both coil packs too). The control side wires from the ignition module to the coil packs are tan/light green and tan/light blue for one coil pack.-----------------------------------------------------------------------------------------

Replaced coil pack on 2000 neon, still no fire on 1 and 4 plug...


The PCM - engine computer has drivers or transistors inside that control the coil's . Three wire's to the coil . One dark green with orange trace is power , should have B+ voltage . The black with gray trace is control side from PCM . for # 1 coil . Testing with a test light . Videos on youtube .

My truck will not start just cranks but will not fire


Air - not likely the problem ! mechanical cable controlled throttle body

Fuel- make sure there is gas in tank! fuel pressure test at the throttle body or rails, if no fuel check power to fuel pump: ignition power to breaker or fuse, relay , power to pump at 3 pin connector near tank/frame rail on drivers side, - if pump is runniig but insufficient pressure, check for mechanical restriction: plugged filter broken or pinched line, plugged pickup tube in tank. if good pressure to rail or body, check ecm : diagnostic codes, fused power, ecm tells injectors when to open, dependent upon several sensor parameter inputs.

Spark- ignition - coil-distributor-ignition module (or coil packs)- wires-plugs-ignition module (signals coil to discharge, mounted beneath distr cap) work backwards from plugs.
