Can you see the injector spray fuel down the throttle?
Can you see the injector spray fuel down the throttle?
You should be able to see the injector spray fuel down the throttle body as the engine is cranked. If not, then the injector and harness should be tested. The injector harness can be tested for a signal with an inexpensive noid light.
Can you see the fuel injector in a car?
The fuel pressure is within spec, so that’s not the problem. Either the fuel injector is defective or the injector isn’t receiving a signal. You should be able to see the injector spray fuel down the throttle body as the engine is cranked. If not, then the injector and harness should be tested.
What causes the fuel pump to not start?
The fuel pump is running and delivering normal pressure to the engine But, with all that working your engine still will not start. So, the most likely cause, is that the fuel injectors are probably not opening. The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.
What causes an injector to fail in a car?
Typically, when injectors fail, the solenoids often short internally, causing a drop in resistance. If the specification calls for 3 ohms and an injector measures only 1 ohm; it will pull more current. Too much current flow to an injector; may cause the (PCM) injector driver circuit to shut down.
Is there no fuel from injectors to start truck?
No fuel from injectors to start truck. When I try and start my 93 Chevy Cheyenne k3500 no fuel come out of the injectors. If I use starting fluid the truck starts and the injectors work great. Has died a couple times while driving, but mostly runs fine and then won’t start one turned off.
