Question about Cars & Trucks
OK , first i replaced the power transistor next to distributor before the engine ran. Then i replaced the distributor with a used one and the engine started working and ran fine even with a misfire on #4 . Yesterday i was checking all brakes on the van and had to move it about 2 feet to get the jack under rear axle. Engine started fine put it in gear, move the van and put it back in park then i just touched the gas and the engine just died . Tried to restart and nothing . Just cranks and no start. Fuel pump works. getting fuel to the engine , has spark but will not fire off. Checked codes and found P1320 ignition signal -primary. Tested ignition coil and that is good too. Any Ideas ? Thanks.
Here is the entire description for the code -
When is the code detected?When the ignition signal in the primary circuit is not sent to Engine Control Module (ECM) during engine cranking or running.
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
P1320 NISSAN Description The ignition signal from the Engine Control Module (ECM) is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit
Possible causes - Faulty power transistor unit built into ignition coil
- Ignition primary circuit is open or shorted (circuit to ignition coils)
- Ignition primary circuit poor electrical connection (circuit to ignition coils)
- Faulty ignition system condenser
- Crankshaft position sensor circuit
Help with this Tech notes The most common cause that will trigger the P1320 code is the ignition coils, one or more ignition coils may have failed. Even tough the coils may be working OK, the resistance for one or more of the coils is greater or smaller that what the Engine Control Module (ECM) is expecting. Measuring the resistance with the coil out of the vehicle may not show any failures, usually the coil fails under heavy conditions (hard acceleration) or certain temperatures.
The P1320 code means that there is problem with the "Ignition Coil" or the wire to the ignition coil. For some models without individual ignition coils the Ignition Coil is inside the distributor and the distributor need to be replaced to fix the problem.

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

There may be no injector pulse if the computor does not see a RPM signal.
There will be no spark if the ignition module does not see a dist pulse from the dist pickup.......a RPM signal.
Because you do not have both ......I would suggest to check/change the dist pick up.
Follow the wires from the ignition module inside the dist to the pickup which is also inside the dist.
If it is just a bad dist pickup....keep all your old parts as good spares.
Also...is the dist turning? to provide a RPM signal?
You will have to remove the dist to change the pick-up.....mark your timing locations......"rotor position" and "dist body location"before removal.
A quick test before installing the "repaired dist" .....plug it in the the truck wiring and turn on the key....DO NOT CRANK THE ENGINE OR YOU WILL LOSE YOUR DIST ROTOR CORRECT POSITION......as you spin the dist by hand .....the injectors should spray.

i just had the same problem in my bmw 325i. Probably vaccum leak or exhaust leak. Check that nothing came loose in these areas. It takes time for your car to learn the new CPS (cam pos. sensor) so give it a few days and reset the code again and see if it works.
