Question about 1994 Chevrolet K1500
I have a 1994 chevy K-1500 with 5.7 and auto transmission. It died on me while driving. It didn't sputter or anything it just died. It will crank but not start. After I towed it home I found that it has no spark or fuel. I have power to the ignition control module and I've changed the ignition control module with a new one. It still does not have spark or fuel. I have checked all the fuses. I performed the electrical tests on the coil per the Haynes manual and it checks out. Coil wire has 2.5K ohms resistance. Pick up coil? ECM? What?
Does your check engine light illuminate in the run position, key on engine off? It should do a "bulb check" by illuminating key on engine off. If it does, now would be a good time to scan it for trouble codes. If it does not illuminate, and you cannot communicate with the ecm/pcm with a scan tool, you need to start by locating a wiring diagram of your ecm, or pcm, whichever it contains. Once you've located a wiring diagram its time to find your ecm/pcm, remove the electrical connector and start checking your powers and grounds to the ecm/pcm. Use a test light that has a significant amp draw to test your power feeds, an ohm meter can deceive you by showing 12v, but that wire may be cracked and full of corrosion, preventing sufficient current flow. You can use this same method to test the integrity of your ecm/pcm grounds by connecting the end of your test light to positive battery voltage, and touching the tip to the ground pins of the connector. If you have good power and grounds, the fault lies within the ecm/pcm.

SOURCE: 2000 chevy venture doesnt start
Not the IAC, or MAF, or 02
Does the Van Crank over?
Have you checked the IGN Relays? 1,2,and 3?
How did the Battery test out?
Anything below 11.9v battery is dead.
So I suggest that you do not throw any more parts and check the battery again.

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.

Yes. First, in the fuse block under the hood check INJ A fuse and INJ B fuse. INJ A fuse is circuit 1039 which feeds the coil. If the fuse is OK, replace the coil electrical connector. I stock 2 of these at my dealership because they are needed quite often.
FYI P1351 is an ignition coil control circuit DTC.
