The crank sensor gets power from the MFI relay just like the injectors and cam sensor do.

SOURCE: 1999 mitsubishi eclipse 2.0L na. no start.

On this model engine, the power to the coil pack is delivered directly from the power transistors located inside the PCM.
If you are not getting the signal to fire going into the coil, verify you are getting a good waveform from the crank angle sensor, and that the wiring from it to the PCM is intact. If the crank sensor is delivering signal to the PCM, and the PCM is not generating pulse via the internal power transistors, the PCM has failed (the power transistors blow open, it is fairly common on this Chrysler PCM).

SOURCE: swapped a 1999 420A engine

first the cam sensor shouldn't be upside down from the 95. they both should be with the plug facing down. they 95 CAS has a different plug than the 99 CAS.
the 95 has round pins and the 99 has flat pins.

also the 95-96 relays are opposite the 97-99

besides that it could be the ecu. i also have heard of the locating pin on the intake cam shearing off, allowing the gear to turn with the timing belt without the actual camshaft spinning.

My 2005 crv turns over but wont start. I just changed the coil packs and it helped for about a week and now doesnt want to start again ?


Since you changed the coil packs, look to the wiring.. When you replaced them you had to move the wires. Two wires go to the coils. One has power, with the key on, There other goes to the PCM. Check the power wire. If you have power, look at the crank sensor.

2001 dodge stratus will the coil pack spark if the vavles are bent


if your valves are bent ,then i take it your timing belt has snapped .which means your camshaft can not turn ., so you can not get a spark at the plugs.if it was the old distributor you would have been able to check the coil with a spark plug tester the trouble is with a coil pack it is controlled by both sensors and your ECU but due to the camshaft not turning so your camshaft position sensor can not tell the ECU to fire the coil pack.

Service engine light flashs when accelerating to speed over 65mph.


Flashing check engine light means that the catalysator can be damaged. There is most probably something wrong with the O2 sensor(s). Did you check for any fault code set in the PCM?

I have a 2002 ford taurus SE, coil pack has been replaced because Advanced Auto ran a diagnostic and said my coil pack was bad. Well its not and im still not getting fire on #3 and #4 spark plugs. changed...


You visually checked for spark and there was none? #3 and #4 show to be on same coil, each coil fires two plugs. Battery has a full charge? The red wire at coil pack is voltage, it has good voltage? Any applicable trouble codes?
The yellow wires with different tracer colors are grounds controlled by the pcm, one ground for each coil. Did you check voltage on ground wire engine cranking? I can't rule out a faulty coil driver in pcm. It's possible your old coil pack damaged the coil driver in pcm? If that is the problem, hope it didn't hurt the new coil pack.
