DTC Confirmation Test
Malfunction is detected when ECM does not receive signal from ignition
primary circuit during engine cranking or running. Possible causes are:
Ignition primary circuit open or shorted.
Defective power transistor (integral with ignition coil).
check fuel pump, fuel pump fuse, distributor,and ignition coil please. then you will need to check crank position sensor.(to do this you need to find factory service manual)
what do you mean by "dash lights"? how do you KNOW the pump isnt working? how do you KNOW its good? at the ignition switch the ORANGE and PINK should have power in the RUN position the BROWN and TAN/WHITE should also be HOT in the run position. There should be a red wire near the fuel pump relay, make sure its HOT when cranking. IF its HOT and the fuel pump doenst run, the pump is bad. You can also put 12V on that red wire and power the pump.
Check the ignition switch, and the wiring to the starter solenoid. Get someone to turn the key to the crank (start) position and check for voltage at the starter solinoid. Check the starter relay and all fuses.
Release the fuel pressure from the fuel line as follows:
Remove the fuel pump fuse at the fuse box.
Start the engine.
After the engine stalls, crank the engine two or three times to make sure that the fuel pressure is released.
Turn the ignition switch OFF and reinstall the fuel pump fuse.
Loosen the hose clamps at the fuel inlet and outlet lines. Wrap a shop towel or absorbent rag around the filter, then slide each line off the filter nipples.
Remove the fuel filter and old hose clamps.
To install:
Place new hose clamps on the fuel inlet and outlet lines.
Connect the fuel filter, being careful to observe the correct direction of flow, then tighten the hose clamps.
Start the engine and check for fuel leaks.
Always use a high pressure-type fuel filter assembly. Do not use a synthetic resinous fuel filter
Sudden death in vehicle is usually based on something electrical.
Check fuses and relays with fuses. Check 1) spark on each plug in turn 2) crank sensor 3) coil 4) cam sensor 5) main relay. Put ignition on position 2 and listen at the open fuel filler pipe for the pre-pump operating. Listen for main pump operation. (If unsure what it is you are listening for remove the fuse for the pump and you nshould notice it being quieter) Check fuel rail for pressure (there is a Schrader 'tire' valve on the fuel rail for pressure testing purposes). If fuel flow is low then this could be blocked fuel filter or tired pump. Finally make sure throttle body is good and clean internally at least and that associated idle air valve is clean and working. With fuel air and spark at the right moment the engine should run.
My gut feeling is the crank sensor
Possible issues could be FUEL PUMP, CRANK AND CAM SENSORS, COMPUTER. I would pull a spark plug wire and see if you are getting spark. If not, the first thing to try would be replacing the cam and crank sensors.
if it will crank but not start check the ignition components and fuel pressure if it wont even crank check fuses and all starting system electrical connections and components
