I think you have 2 problems: 1-Injector module 2-Ignition module
The Injectors don't pulse in both cases because the injector module has a problem. The spark is generated if the ignition module is working by creating a pulse on and of at the primary of the coil. You can generate spark manually by have positive and negative connected at the primary coil, and turn on and off to generate the spark at the spark plug connecting directly to the secondary of the coil. If you have the spark then your ignition module has a problem since it is supposed to do what you did manually to generate  the spark. Hope this can help.

WHY2003 BLAZER ALL POWER WINDOWS NOT WORKING?


A wiring problem or the driver's master switch, probably. Check for broken wires in the harness going into the driver's door opening. A dark green wire is the power wire to the switch (from a 30 amp circuit breaker in the relay block). and a black ground wire from the switch going back into the cabin.
Pull the master switch out and check for power on the dark green wire at the connector, with key on. If no power, wire may be broke from the circuit breaker to the switch, probably in the door opening. If power is good, check the ground circuit from the switch connector to ground. Like this: voltmeter positive lead on the green wire terminal with key on, voltmeter negative lead on the black wire terminal. If voltmeter registers battery voltage, power and ground is good. If no voltage shows on voltmeter, power or ground is bad. Move voltmeter negative lead to a good ground on frame or body. If voltage shows, power is good and ground is lost-look for broken black wire in door opening. Check for the black ground just inside the cabin from door-maybe under the driver's kick panel.
If both power and ground is good to the master switch, try a new or used master switch.

Fuel pump wire color


The gray wire goes from the pump relay to the pump. The black white wire is the ground for the pump. The purple is for the gauge on the dash and the black is ground for the sending unit. I don't list a white wire being used.
If the colors on the truck don't match the tank, you'll have to test them to verify each circuit.

97 GMC Jimmy fuel pump won't come on


Should be a green-yellow wire from the relay to the pump. The pump is grounded thru a black wire in the harness.
The wire from the relay should be hot when the relay is engaged by the computer or if you jumper it.

I just replaced the fuel pump on my 98 silverado z71 and the harness that came with the new pumps wiring is different. the old harness has four wires colored gray on b, purple and white on a, two black,...


I may not be of much help.
According to autozone online, 96-98 model trucks should have - -
gray from relay to the pump
black / white ground for pump
pink - black for gauge ground
pink to gas gauge
You should be able to jumper the pump relay and look for a hot for the pump. You should have two grounds, I doubt it makes much difference which you use for the pump. And then you should have a hot for the gauge with the key on and the relay disconnected.

1991 Accord, ECU fuse is blowing, checked wire from fuse to main relay, ok, tested with another relay, still blows, any suggestions?


Check the power wire at the computer for a short. The computer itself may be bad, causing the fuse to blow. Unplug the computer and see if fuse blows, if it still does, it would probably be in the wiring from the relay to the computer.

Rear Defogger Inoperative, But Heated Mirrors Operate Correctly
1. Connect scan tool. Turn ignition switch to RUN position. Turn rear defogger on. Using scan tool, display BCM
outputs. If rear defogger is being requested on, go to next step. If rear defogger is not being requested on, go to
step 10).
2. Ensure ignition switch is in RUN position. Remove rear defogger relay from rear junction block, located on center
right rear of passenger compartment, under rear seat. Connect test light between ground and defogger relay
harness connector terminal F3 (Brown wire). If test light illuminates, go to next step. If test light does not
illuminate, go to step 11).
3. Connect test light between ground and defogger relay harness connector terminal A2 (Red wire). If test light
illuminates, go to next step. If test light does not illuminate, go to step 12).
4. Connect test light between defogger relay harness connector terminals A2 (Red wire) and B3 (Purple wire). If test
light illuminates, go to step 13). If light does not illuminate, go to next step.
5. Disconnect rear defogger positive and negative feed bus connectors. Connect a jumper wire between defogger
relay harness connector terminals F3 (Brown wire) and A4 (White wire). Connect test light between ground and
positive feed bus connector terminal "A" (Black wire). If test light illuminates, go to next step. If test light does not
illuminate, go to step 8).
6. Connect test light between positive feed bus connector terminal "A" (Black wire) and negative feed bus connector
terminal "B" (Black wire). If test light illuminates, go to next step. If test light does not illuminate, go to step 9).
7. Repair open in Black wire between rear defogger and ground. Recheck system operation.
8. Repair open in Purple wire between rear junction block and heated backlight antenna module. Recheck system
operation.
9. Check for proper terminal contact at rear defogger connectors. Repair as necessary. Recheck system operation.
10. Check for proper terminal contact at BCM. If terminal contact is okay, replace BCM. Recheck system operation.
11. Repair open in Brown wire between rear junction block and instrument panel junction block. Recheck system
operation.
12. Repair open in Red wire between rear junction block and underhood junction block (located in right front corner of
engine compartment, between battery and strut tower). Recheck system operation.
13. Connect test light between defogger relay harness connector terminals F3 (Brown wire) and A4 (White wire). If
test light illuminates, go to next step. If test light does not illuminate, go to step 16).
14. Reinstall defogger relay. Disconnect BCM 32-pin Pink connector C2. BCM is located behind right side of instrument
panel, near rear of glove box. Using DVOM, check voltage between ground and BCM harness connector C2
terminal A3 (White wire). If any voltage is present, go to next step. If no voltage is present, go to step 17).
15. Repair open or short to ground in White wire between rear junction block and BCM. Recheck system operation.
16. Check for poor connection at defogger relay terminals. If connections are okay, replace defogger relay. Recheck
system operation.
17. Check for proper terminal contact at BCM. If terminal contact is okay, replace BCM. Recheck system operation.
