I have a 125cc bike with a delfi ecu and turn bike on and fires then dies not firing again untill i turn ignition off then turn on then same again happens 😢 i have listened to injector and its not tapping even when i try turn bike over 😮 its anew injection unit am really stick on this this is the reason its not starting the fuel. It gets fuel to injector but its n9t letting it past to bike please help me.
@ auto I have a 2014 Chevy Cruze ls 1.8L and I have a p0302 for cylinder 2 misfire. I have changed the coil pack and spark plugs. also I have a app on my phone that connect 2 my obd2 reader and it says to changed the injector but not sure what one or the whole thing. my car will start but it idel real loud and also my rmp will go up but my speed does not. and i also have a like a brown milky fluid in my overflow. please help. also on the obd2 for the fuel Sys 1 it says CL or CL-fault and for fuel Sys 2 it sayes NA but fuel PSI is 58 fuel level is 24.7%
I need help, my 99 Toyota Camry le has a crank no start. The fuel injectors won’t fire. I replaced camshaft position sensor, and my crankshaft sensor seems to be working. The injectors are getting power, and fuel is pressurized in the rail. Something is making the ecu not fire the injectors. Thoughts?
A malfunctioning key immobilizer does the same thing. Other reasons include, malfunctioning fuel pressure sensor, internal wiring short in injector circuit, messed up air intake sensors, leaky drv in diesel head, ecm auxiliary power issues..etc...
I NEED HELP😢 1992 obd1 BMW E36 325i cranks but won’t start. I have tested and confirmed everything in the fuel system works even bout new injectors, and now I see that I have to NO power to the fuel pump fuse and can’t get the fuel pump to prime when turning the key…. I’m out of ideas and can’t find anything about it besides changing the ECM this is my daily driver and I havnt been able to use it since Halloween because of this issue
No power to fuse doesnt mean the ecm is bad....power comes directly to fuse from battery...ecm doesnot provide any power to running parts...just signals the relay. You may find the fuel pump relay and try giving power to relay directly and see if the car starts. Check carefully, If you find no signal from ecu to relay...then this could be an issue with ecm or engine immob.
@@autoinfogroup1629 I did jump the relay and can hear the fuel pump and even bled the system then I pulled the rail out to see if the injectors are spraying or even making noise and I can’t get a response
Hi good people I have nissan np300 diesel crank but no power pulse
There re many reasons like, low fuel pressure, bad crank angle sensor or cam sensor, electrical shorts in wiring, immobilizer faults etc
A good basic Vid for information!
TRUE
Yep, great initial start points.
Thank you and happy to hear...
Thanks very helpful information
Gald to hear brother
Fuel pressure sensor, fuel pressure regulator,fuel pump,cam and crankshaft sensor,ecu..
Very educative.
Hi Nissan hard bord np300 diesel no power pulse
Very good approch symptoms for all technician's.
Glad to hear from you mate....
Any time U well - U are Honestly talking all words was true.

Hi there, if you mean coolant tank with milky precipitate, likely you have a blown head gasket.
Check wiring for bad connections befor change any parts coil and injector circuits.

@@jadeshaw1867 I couldn’t figure it out. It’s been sitting there for a year. Sorry partner, no clue what happened.

I also replaced all relays with oem ones
