Question about 2000 Chevrolet S-10

89 s10 2.5 has fuel and fire injector has power but no pulse

Ran wires to replace red and blue wires on fuel injector, plus replaced egr solenoid wire all the way to computer, replaced plug on injector as well, had module on distributor tested its fine. does anything running from distributor to computer control injector pulse? injector is running wide open just dumpin gas. any help really appreciated.

    no fire or melted wires just looking for a short or something. this all started with a tune up ( cap,, rotor, plugs and wires)lol. it ran fine before this

Injector pulse is just controlled by the ecm or computer as some would say,u said u replaced wires? did u have a fire or melt wires? ecm is known to go bad on these,had a few of these trucks back in the day.

90 300zx fuel pump works its getting spark be injectors wont open what can be the problem?


Possibly a computer (ECCS control unit) malfunction, but first check the white/black wire going to each injector. All should have power on them with ignition key in on. This white/black wire comes from the computer's pin # 58, then is spliced to all 6 injectors. If no power to injectors, check the wire continuity from the ECCS' #58 pin to the injectors.

The ground wire from each injector also goes into the control unit, but individually, so that the control unit may ground the injector circuit and cause pulse.

If the wiring is good, no breaks or shorts, it may be a computer malfunction, but first find out if the variable valve timing affects injector pulsing. I don't know anything about it, but you have 2 VTC (valve timing control) solenoids, one for each side of the engine. Both are located near or on the firewall behind the engine, near the middle. Looks like 3 solenoids there, the middle one is the EGR solenoid, and the VTC solenoids are on each side of the EGR solenoid. Best I can do from a very poor wiring diagram I was looking at.

You checked for spark, but did you check on all six plugs for spark?

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.

89 pickup 22re. no fire on no. 1 cylinder


It could be a fault in the wiring for #1 injector, or a defective spark plug in #1.

All four injectors have a hot wire to them with key on, the same black with red stripe wire is spliced to all four. Check if #1 has this hot wire with key on. The injector ground wire for #1 and #3 is a white wire with red stripe. These two ground wires splice together before the ground wire enters the computer. So the computer pulses #1 and #3 injectors simultaneously. (Injectors 2 and 4 have a similar set up, with a white wire being their ground.) If you have a hot wire to #1 injector, but no pulse on it, but #3 injector is pulsing (putting fuel into the cylinder), then the ground wire for #1 may be broke before it connects with the #3 injector ground. The wires and the splice are probably buried inside the engine wiring harness, so one could check for continuity on the ground side for 1 and 3. With key off, use an ohmmeter and check resistance between the grounds for #1 injector connector and #3-check on the harness side of the injector connectors-it should show low resistance-low ohms value. If very high resistance is shown, trace the ground wire from #1 injector.

1988 Chevrolet k1500 350 v8 not getting signal to fuel injectors


So, it's the injector circuit. There is a 10 amp injector fuse in the fuse block, on left side, 4th one down. Check this fuse. It supplies constant power to both injectors, on the red wire to injector 1, and a white wire splice from this to injector 2. A steady 12 volts anytime key is in on, run, or start. You can check this with a test light or voltmeter. Ground the test light and probe injector connector's red wire on injector 1, and the white wire on injector 2-both should be hot with key on.
This may be why the noid light didn't blink. The noid light must have this steady power signal, and when the computer internally grounds the injector ground circuit for a split second, you get injector pulse-or a blinking noid light.
You can check the ground circuit separately with a test light also for each injector. Place the ground clip of test light on the POSITIVE battery post, and probe the blue (ground) wire on injector 1, the engine must be cranking over, and the test light should be blinking. Do the same for the green wire on injector 2. If the test light is blinking on both ground wires, with engine cranking-the ground circuit is good. You are sending power down the ground wire to computer, and when the computer grounds the circuit, the tester will light up-it will blink because the computer only momentarily grounds the circuit to cause pulsing of the injectors.

1989 caprice with 350 tbi injectors won't pulse anymore


If you have spark, the computer is getting the signal to pulse the injectors.
If you have power but no ground pulse, you may have fried the driver in the computer again.
You could get a used computer from a junk yard to test it.
There could be a short in one of the injectors or the harness at the computer, or a break in the circuit from the computer, and that could kill the driver in the computer.

look for a bad ground, you can try running a new ground from the battery to the body, i had an 89 corsica that would not fire until i ran the new ground wire.

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.
