Motor starts then dies

[MommaBurt]

I've seen (mostly heard) about turbos sticking closed and then the engine won't start. Sometimes it is the actuator and sometimes it is the turbo.

I thought and posted this initially, but usually will run fine all day if it starts. Seems like he's got something going on causing him to lose prime.

I’ve seen this also, usually there is a very dirty egr system or bad injectors right before this happens.

This was my second guess, and a friend of mine brought his computer over and the problem is the actuator, they got it running enough to get to the shop, they are looking at it.... he thinks it's fixed, but i am probably going to have him throw a new actuator on it anyway.

The truck once it starts runs great all day, boost looks normal under acceleration, and with the jake on.... Figure replace actuator to make sure I don't have that problem out on the road. Luckily, the only time it has done this is when I am at home getting ready to head out....

most people completely ignore that expensive actuator and turbo until it goes out on them. Grease dries up, motor burns out because of it, etc.

There is a way to service them and keep them alive for many years and miles ...

Thank you very much

Well unfortunately, looks like my turbo and actuator are dead.... I went to the shop and the lever in the turbo is very bound up and you can feel it really doesn't want to open up.... so I will be replacing the actuator and turbo to the tune of some serious money..... thank you all for the info, I will be trying to service whatever I can in the future and save my turbo and actuator... I have to get back on the road soon to start making more money......
