injectors or regulator?

my car starts the first time and will run for a about 15 minutes if you drive it around. but it will eventually stall and not start. I no the problem is the fuel. I know this because, one the old sparkplugs were all black and my muffler is all black which means the cars running rich i think. And second you can smell the fuel.

I narrowed the problem down to either regulator or the injectors because i replaced the filter and the pump i’ve seen manually working. So what i needed help with was how i can manually at home check to see whether the regulator is the problem or the injectors and if injectors which ones.

I have a sad story with my car, because i haven’t even driven this car a full tank without something happening and now i really need the car for work. So help me out guys.

Thanks,

not sure how to check the reg, or injectors but you might want to check your o2 sensor as well if your running very rich

how can i check if the o2 sensor is working or not working?

4

remove it from the exhuast and check the color and condition, if you have the chance try another one just to compare how it runs

thanks

anyone got any ideas on the injectors?

use the yellow pages. There is a company here in waterloo that tests injectors for $2/each. there must be a similar company in the GTA.

Euro-Drive ? Almost positive he can flow test + re-flow Injectors…

Rule out the regulator. If the regulator was bad you have a long crank, from not holding pressure in the rail. What makes you think you would loose injector pulse while driving? A bad oxygen sensor won’t cause a stall, at least I never seen it or heard of it.

yeah, that does kind of make sense. Does anyone know a place in Brampton where i can go get my injectors flow tested. I checked the injectoers my self to see if they were stuck using the meter and all of them had like 12 ohms. But the car hasn’t had the problem for a couple of days since it hasn’t been running for a month. So I doubt the numbers mean anything.

If anyone know’s a place where i can get the checked out and fixed if they need to be give me a shout.
