SOURCE: pcm is not grounding injectors. need a pin diagram and ground location diagram

Ground points are in different locations throughout wiring harness. If you had any work done to engine it is very possible to have missed one of the grounding eyelets during the process of putting things together. Check along wiring harness in any area you can see or reach to try to locate any loose or disconnected ground looks.

SOURCE: what does the code P0688 mean

code P0688 Auto Shut Down (asd) relay sensor circuit is low. Could be a bad or dirty battery connection. The other that could be going bad throwing the code is a bad Body Control Module (bcm). I would start with the battery, is their corrosion, has it ever been replaced, low cells?.

Why am I nit getting a pulse to my injectors?


.

OBDII Problem related to the computer controlled system not sending a signal to the positive injection banks. Could be cam or crank sensor problem as well. These systems works on Ohm resistant's and the introduction of a 12 volt tester could compromise the system.

My injectors arent pulsing on my 1989 k1500 suburban. I have 12 volt power to the injectors and have replaced the module in the distributior. Any one have an anwser for me


The injector ground circuit must not be working. What causes the pulse is when the computer internally grounds the injector circuit, power is passed across the injector solenoid terminals. All the injector grounds are spliced together on each bank of engine, and run into the computer. So, injector power, but no pulsing would seem a computer malfunction as long as the ground wires are good. Did you check all the injectors for pulse with the noid light, or at least both sides of engine?

No injector pulse


1991 this make you OBD1 . You can access a code by jumping 2 terminals together.The injector pulse is from the PCM . If you have no pulse you need to troubleshoot for spark first . If you dont have spark do spark first then injector pulse comes on. If no injector pulse check fuse in engine junction box.Use a volt meter check grounds at PCM. If all else checks out good replace PCM. You may also want to check the TPS. If this sensor short out in the WOT position you also wont get injector pulse.SO disconnect the TPS. and recheck for injector pulse

po522, the possible solution:
The most likely cause is a faulty oil pressure sensor/switch.
for p0688, you can Check all the ECM fuses, if the fuses are OK try replacing the ASD relay.

88 cavalier has no spark


you need to start somewhere. get hold of a scanner and see if car has a crank signal. the crank signal supplies refrence for both base for ignition and injection pulse. if it has injector pulse and no spark, look at the ignition module/ coils but if has neither look at the crank sensor or harness to the module
