I have a starting issue with my KA. Help please!!!

[NissanPride247]

I got my 89 240 a few months ago and it had been sitting for a couple years. The motor is from a junk yard with about 30 grand on it. It has a bad starting problem. It takes quite a few turn overs and has a rough start. I don't know what it is or what it could be. Some help would be greatly appriciated.

describe sounds, and how it feels when it starts up.

first thing that comes to mind is your timing is probably off, be it cam timing or dizzy timing.

try to get a more detailed description on whats happening and we'll have an easier time helping you out.

also, there is a KA forum.

I had a starting problem with one of mine that sat around for a while. After buying a new starter and swapping batteries it came down to the battery terminal clamps just needed to be sanded down for a good conection. I wasted $90 troubleshooting by replacing the starter.

Point being, try to start small. with the info provided it could be one of a hundred things.

K I'll go fire it up and have a better description.

Well to me it sounds like the motor is getting choked from fuel. It takes a few turn overs and then it starts bogging into and idle and gets going. There is small ticking at like 2500-3500 rpm. Not at idle just small small tick noise. A few buddies have said its the valves so depending on the answers we get here we may be taking the engine out and replacing gaskets and what not. And can you do a valve job w/o taking the engine out? And what consists of a valve job. how to do. what to do. what to check.. Any and all info is well appreciated

[NissanPride247]

Yeah like he said it sounds like fuel isn't fireing right, bogging, etc. Willing and able to do any work needed. Let me know I'm itching for work!

[s13_chris]

Yea. Now that you are suspended again. Anyone got any answers? I think its stuck valves. How easy is it to check/fix?

[slo_coupe]

when it starts do u smell fuel? if so u may a have a leaking injector which is common on ka24e's. i have 2 leaking injectors, they only leak on cold temp day below 50* any temps above that its normal though. if u wanna check for leaking injectors pull ur spark plugs and look in the cylinders for wetness and a fuel smell. only check if the car has sat for approx 1 hour.

I'd check the spark plugs, plug wires, distributor cap, ignition coil and rotor. Sounds like a ignition related problem. Make sure the wires are going in the proper order as well along with the firing order. This engine fires in a 1-3-4-2 pattern.

I dont think the valves will cause this problem....if you think so, do a compression test to find out.

^^^^^ A leak dow test will be better for valves but if it were valves it would constantly run rough not just on start up. like i said before check for a leaking injector. its a known common issue with ka24e's. dont just throw parts at it either. diag properly to save money and some time.

You might be right, i used to have a studdering problem at lower rpms on my 90 S13 but when i gave it more then half gas it would smoothen out. wierd.

[NissanPride247]

Wow thank you. I had check the plugs and wires before I even started the car and they were good. It doesn't have a fuel smell but I will check for wetness in the cylinder. All the ignition stuff looks good. And it runs real smooth once it starts if you look past the slight tick at 2500-3000 rpms. I also ran a compression test and it was perfect in all four. All this info is GREATLY appriciated. You people are the people that makes Nico so great! I will keep this updated as much as possible.

All the other sugestions are good but if your car has sat for a coouple of years, How good is the gas you are trying to burn? Make sure youhave fresh gas and then see how it runs. I would haate to see you speen a lot of time and mony trying to fix a problem that can be improved or fixed with a trip to the gas station. Your car might run on old gas, but it won't run right.

I would suggest running some Seafoam in the crankcase and the fuel to clean things up a bit. That stuff works wonders on 300ZX's should be just as good on a 240.

[NissanPride247]

The gas was another good question and I did go put about 5 gallons in it. So it was a mix of good gas and crap gas. So maybe when I fill up again it will be better. And I was just talking to a friend that has a 300zx And he sugested seafoam too. So I will give that a shot. Once again thanks for the sugestions all are appriciated.

Yeah, it works good in the crankcase in case you got sticky lifters and gunk in it that makes it make noise. Running though the fuel tank will clean out the fuel system of gum, carbon and varnish. I mean dont drive it with it in the crankcase though, its just a flush before you do a oil change and let it idle with it in there to clean everything out.
