fuel problem

[ac92pathfinder]

so sunday i went out there tryin to start it up. runs for like a few seconds and dies then has a hard time tryin to start it up all i hear is a back fire in the air box with smoke coming out of it. but when it did run wood burning coloring smoke came out of it (whitish grey) then blueish grey smoke then it went to black powder smoke coming out then stops from there. i dont know whats goin on. im thinking my next step is the fluel pump. i have a new filter in there. im thinking it maybe one of the injector to is clog cause i hear it clattering when i drive it underload. its like when i start it up seems like a clould of smoke comes out then quits after awhile and its thick too. takes a few times of tryin to start it up to keep it running when it wants too. hopefully i didnt ruin anything when i ran out of gas on it .

pretty sure white smoke means burning coolant, blue smoke is oil, and idk what black is. But blowing white smoke or blue smoke is normally not good. Are you sure your getting good spark? you might have flooded it out and its doing that due to poor spark. check your plugs and wires. I would also check and see if you have oil in your coolant or coolant in the oil. If so head gasket might have went. my guess is spark or fuel pump though. can you hear the pump when you turn the key to on? you should hear the pump humming.

i'll check all those tomorrow or my next day off. but im gonna look for coolant in the oil or reverse. thanks im looking on get a pump for it.

[edicer2]

yeah np idk if that stuff will work but thats stuff i would check. i would wait to get the pump until after you check the plugs. if the plugs are garbage then a new pump would just do the same thing. You could just be flooding your motor out. if the plugs are all white (very white and alot of it)on the end then its not enough fuel(in that case get a new pump). if they are soaked in gas then you have a spark problem. and i would look into new plus wires cap and rotar. possibly a coil?

[ac92pathfinder]

hey thanks i pulled the plug on the passenger side front and it had gas on it so i might have gas in my oil cause when i checked the oil it was alittle over full but i dont smell any gas. i did see any oil in the coolant. thanks for the fast reply

[edicer2]

well i would say that you are having a spark problem. I would say new plug wires cap and rotor would hep but thats just me. if you havent done that in a long time it might be a good idea anyways

[ac92pathfinder]

i needed those for along time. i just had the car for a few months deaqler care. looks like next few pay checks i will get it. it was soaked with gas was damp black the plug. all this happened after i ran low on gas. thanks for the replies

Black smoke is too much fuel in the mix.

[94extreme]

black smoke is a rich condition.

 

what color is your oil?

[edicer2]

my guess is hes having a bad spark problem so plugs wires cap and rotor will fix it i bet. coil might have gone out. idk i have one if u need it.

[ac92pathfinder]

thanks for all you replies. the oil is a normal color but i dont smell any gas but it looks like the oil went fuller like half inch on the cables. the plug i pulled out was totaly black and smelt like strong gas. i may have flooded it when i tried starting it after the fuel filter change. all this happened when i ran low on gas. thanks

[94extreme]

i never read your other thread.. i guess i'll have to catch up..

[edicer2]

yeah get new plugs and stuff and go from there those are fowled out

[adamzan]

You can also burn the carbon off with a torch.

i also heard its a good idea to run a compression test while you're there just to make sure its not the rings

[ac92pathfinder]

so i should just change the plugs and oil cause thats all i can replace for now. thaat should solve it hopefully.

diesel in gas not so big problem, drain it.. change filters.. maybe new plugs

so im allright then just drain the tank and put new filter and plugs? im doing all this under his expense i might have it towed to the dealer if i can and have it fixed or my mechanic. im not so happy best for the insurance to talk to them instead of me cause id be goin off the insurance used them for road side assitance. so im waiting on a phone call

this happened a few times to davesfarm on youtube, and he fixed it pretty easy with some work.....he just pumped the diesel out via battery to the fuel pump, then filled er up with gas and let it burn out....go check it out on youtube...
