How can I find out if my turn signal is bad?
How can I find out if my turn signal is bad?
Locate the fuse using your car owner’s manual or vehicle repair manual, or check the ‘Checking a Light Bulb Socket for Ground and Power’ section above, or the ‘Testing the Turn Signal Flasher’ further down. Check the bulbs condition. Make a visual inspection of the bulb sockets – look for corrosion and damage.
Can a test light be used to test a turn signal?
You can use a test light here: After removing the bulb, clip the test light to the socket wall (ground) and touch each socket contact inside with the tip of the test light. Have an assistant operate the turn signal. The test light should flash—otherwise, there something wrong with the ground or power connections.
Is there a turn signal for both left and right?
Although some models use a separate light for the left and right turn indicators, other models use a single light for both turns. If your instrument panel has only one indicator light for both left and right, check the flasher unit. Some vehicle models combine the brake light, taillight and turn signal into one light bulb.
Is there an ECM signal to the fuel pump relay?
The fuel pump relay works as it should. I always have power to Pin 30. I believe the ECM tells the relay to work via the green/black wire to Pin 85. This should happen for 2 seconds when the key is turned on. I have tested this when the issue is occurring and have confirmed that no signal is being sent from the ECM.

What is the est / spout signal on a HEI ignition module?
The EST/SPOUT signal is the same as is found in many factory ECUs. It is a +5V square wave trigger that is used to drive an HEI ignition module. Because of that, it can be used to control timing on a GM Small Cap HEI or Ford TFI distributor.
How can I tell what year my Chevy Silverado is?
If it gets to that and you want help, provide the year, model (there is a Silverado model in some years, but in others it’s a trim level, not a model – if it’s a C1500 2WD pickup, that’s what we’d need to know), and engine size (liters, not number of cylinders). With that info, I can find the correct wiring diagram and give more accurate advice.
Can a GM small cap HEI control ignition timing?
That is why it cannot control ignition timing using the the GM Small Cap HEI or Ford TFI ignition. It can, however, be used to control the timing on a fixed-advance distributor provided that the rotor phasing is correctly advanced.
