240sx major problems!

[Dope909]

Hey guys, I am actually posting this for my friend. He got a 90 240sx, and did a motor swap with another single cam ka motor. He finally got it running but here is the list of issues he is having with it..

swapped in a new ka that im 100% sure runs since i drove it before it was pulled.. and i just finished bolting everything up and now i have a list of bad problems
anyways heres whats going on

-wont start/stay on unless i give it gas

-violent shaking at anything under 1500rpms

-when i floor it when its out of gear it sounds like im doing a 4th gear pull going like 20..it takes years to get up to any rpm

-smells like fuel after shutting it off(running rich??)

after i killed it i got out the car and saw it was smoking on the headers and smelled like fuel so what seems like fuel on the headers heres a pic of exactly what it looks like after running it for about 30 seconds at 1500rpm

He just installed a new maf sensor, and o2 sensor. It helped the car at higher rpms, but thats it. Here is a picture of what it looked like after he started it ..

sounds like the timing is off. was the oil pump/distributor removed at any time?

Check the plug wires to see if they might have been installed in the wrong order. Thats what it sounds like to me.

Definetely sounds like a timing issue.... the distributor might be off by one tooth. I had this issue when I rushed to get my motor running the first time.

it would actually be the oil pump off by a tooth, and yea its a bitch lol line up the punch marks on the pump and shaft slide it in at tdc and you should be cool

Definitely timings off

[Dope909]

He got it running fine after he replaced the wiring harness. He still had a rough idle, so I got a chance to look at it, and it has a vacuum leak.

I hate tracking down these kinds of problems, the symptoms match so many issues. Good luck though.

Make sure the spark plugs are tight, and he has gaskets on all 4
