Hi, new member, old car. This is a little vague as I should have planned it better…car I was told is an 06, 4 cyl…not sure of the size, didn’t look. Approx 130,000 miles. Tuned up a few months ago. It ran for 10 minutes and then died…
Will be going over in the next few days to try to revive it…and get solid info. Here is where it is..
Engine cranks, gas is pumping from the pump, I disconnected it from the fuel rail line to check. Car has spark, I pulled plug and watched for spark, car will run of gas is let into intake, dies when you stop.
So I assume fuel is not making it past the injectors. I could be wrong hahaha….
I did not see a fuse that said injectors, or anything obvious….
Does anyone know the voltage at the injectors so I can test them? Can the pump not be pumping enough?
Im pretty awful at troubleshooting….thanks, appreciate your time and thoughts.

Also, is there a service manual available anywhere on here?

 

any codes in the computer ?

usually i've seen injectors DIY tested with a 9v battery, but I wouldn't recommend keeping it active for very long. just pulse it a couple times real quick to see if you hear it working.
there's plenty of DIY fuel injector cleaning videos out there, but if you want them cleaned and tested I'd send them to Fuel Injector Clinic.

 

all injectors just stop at once because they are dirty? Seems weird but I’ve never messed with them before…

tried the screwdriver stethoscope trick, didn’t hear anything that indicated power. Trying to find a ecu diagram to backin and or a diagram of injector fuse/relay….

 

admittedly it's rare, but if the pump sucked up a bunch of trash and pushed it through, it could foul all 4 injectors.
injectors are run off the ASD relay iirc, but so is spark, so if you've got the latter you should be good.
eta: can confirm... ASD relay feeds FUSE 26 which is +12v constant to the injectors. so check that fuse in the TIPM.
eta2: FUSE 23 powers the coil via the ASD relay as I suspected, so since you saw spark that proves at least power to the TIPM.

can you detail what you mean by "tuned up" exacty?

 

funny to mention that: we're getting close to the season where mom's should start randomly throwing a P0128 when the ambient temperature is just low enough, but not too low.

 

Interesting, I’m not ruling it out but I’m really suspicious about power to them.
has spark for sure ran good with fuel input manually..so need to test wires at injector next. Should probably just order injectors now anyway…
thanks for the location, I’m not googling very good I guess…cant find much on diagrams …
just basic time up, spark plugs, wires, coil pack, air filter, oil, etc.
what do you think about the aic being wonky?
im annoyed it’s not throwing a code…

 

work one problem at a time, and check fuse 26.
note the ASD isn't going to stay active unless the engine is cranking or running, so consider that.

 

all fuses checked. All are good…
