black smoke coming out when i start my machine

[jcarloswestcoast]

i bought a 2004 genesis nxt 59 , but after 20 minutes shuts down so i replace the fuel pump and did not shut off but yesterday when i started it, black smoke came out for like 5 minutes, the fuel pump that it has before was the walbro gsl 395 so i got the same, what could it be now? thanks for your help!

Getting to much gas. Is this engine carbureted or fuel injected? Does the black smoke go away when you increase the rpms? Bad fuel pressure regulator?

 

[jcarloswestcoast]

it is fuel injected, yesterday it took like 10 minutes but turned it off because smelled and smoke! that was with new fuel pump , i put back the old pump today, and it did same!

 

[jcarloswestcoast]

and also i replaced the spark plugs, 2 of them were duty

Is it running rough?

 

[wilpath]

check the coil packs if u have them

Hows the Air filter and oil condition and blower filters?

 

[jcarloswestcoast]

we changed the oil and air filter, wast tank filters are clean, with the old pump the engine runs fine, with new pump runs rough!

 

[Shane T]

Are there not trouble codes?

 

[jcarloswestcoast]

where do i look for the codes? where can i get a pressure regulator for this machine? it is the nissan engine A15 2004 thanks

I'm not familiar with the Nissan. Normally there is a procedure where you can turn the key on a certain amount of times and the run light on the front of the unit will begin to flash a sequence of codes. You may also be able to find a Nissan mechanic who can plug it into a computer to read the system.
The fuel pressure regulator typically is placed after the pump with a return line going back to the tank. Sometime the regulator is incorporated into the filter.
I'm sure there are guys here that are more familiar with the Nissan. It was widely use with a good reputation. Might want to post in the Hardware room.

call the guys at wolfequipment.net they are the ones that made that machine. They make the wolf aloha 440 now.

[Nate The Great]

There is no aloha in that thread...

 

[Lee Stockwell]

Nissan Forklift shop can do it.

You might be dumping fuel into the engine through the fuel injector if it stuck open. I thought I might have an injector and regulator but I must have given them away when I sold mine. Call Mike Farmer at Zenith. He could help you. His number is 276-645-8632.

The injector and regulator are easy to replace. they both are in the throttle body. Injector on top. Regulator on right side of throttle body towards front of vehicle. Injector costs around 150 or so.

You can check the trouble codes by turning on the ignition. let it go through two or three sequences of blinks. I think the codes go from like 12 to 18. For code 12 it will once then twice more. For 13 it will blink once then 3 more times and so on. If you can find a Genesis manual online, it will have the codes in it.

How much did the regulator cost you? Did they give you the old one back?
