I have a 91 2.4 HB. 241,000 on the clock. I am having a wierd issue with it. When the motor gets to normal operating tempature, if you cut if off it won't restart. It turns over very slowly, almost like it has a weak battey. I thought is might have been the starter, so I replaced it with no luck. I then thought timing was off, checked timing, still no luck. I have cleaned the engine grounds and it has a recent tune-up. Any ideas of what it could be? I'm lost.

I don't think it's a fuel issue. It runs great for the mileage. The only other issue is it misses while idling. It does it at complete random. It averages 21mpg mixed driving. I'm thinking it's in the valvetrain, but I wanted some other thoughts.

It could be the dizzy. I have also read that the pick up in the dizzy could be bad. I took the cap off today and it looked good. The contacts were still nice and clean. It really bugs me. I have another truck to drive but I'd rather drive the Nissan. It's a fun little truck. I just hate that I can't turn it off if I go somewhere... LOL

fuel and spark should not be causing his problems if i understand him correctly it is turning over very slow which is causing it not to crank
Exactly!! The only way it could be a fuel issue is if it was filling the motor up with fuel. That would hydrolock the motor. It gets good gas mileage, 21 mpg mixed, so we can rule that out. I have checked the fuseable links at the battery, they are good. The best way to descirbe it... It turns over very slowly almost like the battery is dead or the starter is bad. It only does this when the engine is at normal operating tempature. Yes, BTW KA24E.

Ok guys, going off a hunch, I tired something yesterday. Now I have only expierenced this problem when the motor was hot. Now, yesterday I started it up, then I immedately turned it off. I restarted it, it dragged but started. I tried a third time and there the problem was again. It wouldn't start, just turn over slowly. So I took the battery out and had it tested twice. It's bad.


I assume the first time I had the battery and alt tested, they guy doing it didn't do the battery or was to stupid to know how to read the machine. So, I am picking up a battery tomorrow and I wil let you guys know the out come.

So I installed a new battery yesterday and it's still doing the same thing. I checked the timing and it's right. The only other thing I can think of is the valves are too tight. I have had one person on here say that their adjustable and someone else said their not. Anyone know for sure?

Remember I have replaced the starter, battery, cleaned all grounds, checked timing.

I've had the exact same problem on my chevy a couple years ago and my hb a month ago. Its the starter. Have you had it checked? As the starter wheres out it needs more power to work. When they are warm there is even more resistance and they need more power. Get a new battery and new starter and it'll be a world of difference and you'll see that the starter has probably be been getting slower for a long time without you noticing. A bad battery usually makes the problem apparent.
With the valves, they're hydraulic. The only thing that can be done is make sure there is plenty of oil.
As I have previously stated, the battery and starter are brand new. Those were not the problem. However, the battery cables were the problem. I replaced the positive with 2g cable and the negative was replaced with 4g.

PROBLEM SOLVED!!!!!:fluffy:
