Injector issues. My 1995 1500 has one injector working fine and the other doesn't. It has constant power on the orange/pink side of the connector but no pulse. It doesn't light a noid light. What should be my next point of attack? Distributor? Control module?

You need to find out if the "no pulse" is from the power side or the ground side of the injector circuit.

For the power side, check the 15 amp injector fuse. With key ON, all injectors should have constant battery voltage available at the injector. Check with a test light or voltmeter at any injector connector. One of the terminals should have constant power on it with the key on. If you have power to the injectors, you would next check the ground side.

Post back with what you find. I can tell you how to check the ground circuit with a test light.

Check the ECM 15 amp fuse, position or fuse #3 in the fuse block. This fuse supplies power both to the injector and to the ignition coil. The red wire to the injector is the power wire, and it should be hot in run or on. If no power on the red wire with key on, check that the coil has power to it on the pink and black wire. If the coil has power, but none to the injector, the red wire is open between fuse #3 and the injector.

If the red wire has power, but the injector doesn't pulse, check the blue ground wire from injector to the ECM. The ground wire may be broken. When the computer internally grounds the injector circuit for a split second, that is what causes the pulse. The injector has constant voltage to it on the red wire when the key is on.

To check the ground wire for continuity, use a voltmeter set to ohms, one lead on the blue wire terminal at the injector, and the other lead on the blue wire pin at the ECM connector that has that blue wire. Take the connector off at the ecm. (take the negative battery terminal off first.) You may have to use a jumper wire from the injector terminal towards the passenger side, so the ohmmeter leads can reach between the ecm connector under the glove box, and to the injector. If the ohmmeter shows low ohms-low resistance to current flow-then the wire is good and not broken.

Guessing when you say pressure that you have fuel pressure and that the fuel pump is working but the injectors aren't pulsing and injecting fuel into the cylinders. The way your fuel system works is that you should have constant power at each injector and the vehicles computer (the ECM) gets readings from different sensors and send a quick ground pulse in order to complete the circuit. each time the ECM sends a ground pulse, that's when the injector injects fuel so the ground signal/pulse is quick (on and off, one and off..you get the idea). The first thing I would do if your fuel pump is pumping and you have fuel pressure is check the fuse. The fuse you want to check should be a 20 amp fuse in the fuse panel under the hood of the vehicle in the engine compartment. Below is a diagram of the fuse layout and I have marked the fuse you need to check (the ECM 1 fuse). If that fuse is blown you will not have that constant power at the injectors. If blown replace and that should solve the problem unless it blows again which would mean you have a short. If it isn't blown make sure you have power at all time when the key is on. The pink wire at each injector should be the power wire. If no power you need to locate the open wire for that circuit (coming from that fuse to each injector). This is where I would start. If you need further instructions as far as any more testing procedures, reply/comment here or feel free to email me directly at [email protected]. Hope it's as simple as a fuse for your sake and I hope this helped.

You may be geting gas from the fuel pump but are the injector working or do they have power going to them. You can check the dark green & orange wire at any injector. Also check for power at the plug of the coil (there are two together but both get power from one place). The power wire for the coil also happens to be dark green and orange. If you are not getttting power to either one, check the auto shutdown relay (ASD). This relay stops power to the injectors and the coil but the fuel pump will still work. It doesn't shut down the fuel pump. You can let me know here or you can email me directly at [email protected] with all your information and I will be happy to help and no there is no cost. Just need to be sure if this is the case first (the ASD relay) to go any further. Also if you have a turbo this information isn't correct as far as the wire coloring goes.

The power is supplied in the engine fuse junction box located bottom right side of engine compartment.It is a 15 amp fuse. This is for power,for the injector also check ignition fuse while you are in there.

Sounds like your injectors aren't opening if it holds that pressure. Get a "noid light" at parts store that fits your injector harness connection (just a few bucks). Just pull connector off injector and plug in noid light. When you crank engine, the light should blink rapidly. Try all of them, or at least one on each bank (side).
If light doesn't blink, then check your injector electrical circuit. Power to them is fed through your ignition switch, and the ecm grounds that particular injector at proper time to make injector work.

Probably the wire. Check continuity of the wire from the computer to the injector.

could be a distributer or coil or plug wire

The ECU / PCM has a transistor in side that controls the injector , Need PCM/ECM . Videos on youtube showing how to test injector driver .

Check the pulse on the two injectors.Purchase a noid light at the parts store,that will fit the injector harness,see if the noid lights will flash,if they do,then replace the injectors,this would be the only thing it could be.If the noid light is not puling,or flashing,then the computer is the problem,seeing it is the distributor of the pulse on time.
