The drivers in the ECU control the pulse width, You could have a problem that would burn the driver out, I dont think it could burn the injector, there is nothing in the injector to burn out, it is a pintle that opens and closes base on current sent to it. Like an electro magnet. have you checked the fuel pressure regulator? or maybe a pinched return line back to that tank that bleeds excess pressure off?

That year model i believe is tbi not fi so you should have only two injectors in that car in the middle of those is a little diaphram when you got the injectors you should have gotten a kit with replacement parts for that also it doesnt come as a big kit but whoever sold you the original parts should have expressed the urgancy of purchasing that as well go back and get that kitit should fix it rite up

The injectors open and close to feed fuel to cylinders based on data they receive from various censors. If the wrong info is fed to the ecm, this results in the injectors opening too long or too short what ever the case may be. Check out all of the sensors involved in feeding the ecm - Example: if there is a cold start sensor that is not working properly too much fuel will get in there and ......................

Hi and thank you for using fixya:

I would like to start by asking you several questions:

1-how many miles on the car?
2-is the car smoking through the tailpipe?

If the car is smoking there is a possibility of having bad piston rings although it is very rare for the gas to pass down the cylinder.

Car not starting, no fuel getting into engine


Start with checking your fuel pump and injector mini relay. Fuel pump relay is #18 and injectors is #48 and is located in the fuse box under the engine hood.
Also inspect your ECM fuse, the fuel pump get's it power from the ECM fuse and at wost. It's your fuel pump that has gone bad and that is located in the gas tank, but make sure your fuel filter is not to dirty causing fuel restriction and replacing that will address that issue.
Thank you for using fixya and keep us posted.

On 2005 duramax injectors, is there a recall on this issue


05 duramax injectors have gone bad I'm told because the ecm has gone bad. Is this the case or I'm I being told a crock? They say it needs 4 injectors. While I was driving down the road it started missing and then it would quit and start missing again. After about 6 miles it died. After changing the fuel filter and priming the system it would not start unless assisted with gas vapor. It will run for a few seconds (20 or so) very rough with no power at all and then would die. Does Chevrolet have any recomendations or will they give any assistence with this problem. I don't think I'm the first person that has had injector problems with the Duramax .

Thanks

2003 chevy cavilar, won't stay running


It sounds like you may have a cloged fule filter, start with that and then check to see if your fuel pump had gone bad. Most likely it's your fuel filter if it's never been changed. The other common problems is a partial clog to the injectors but i don't think that is the problem here. Good luck

1997 eagle talon fuel injector problem


dsm skeem/ The wires from the injectors run right back to the cars E.C.M A bad wire or connection at the computer harness may be the problem. check for signal at the injector connector using a noid test light. If u do have power then its more than likely the injectors are bad.
