slow cranking, 93 KA24E
 
My 93 (KA, 5 speed) starts fine the first time, but if I stop and say run into a store and than go to start it, it will crank real slow and the volt gauge will go down to about 8 volts.

Battery is fairly new and over sized, alternator is putting out very close to 14 volts when no accessories are on, belt is tight, checked and tightened it today.

I replaced the connection at the positive battery terminal that goes to the starter, and the terminals are new and clean and tight.

Haven't looked at the starter end of the cable yet.

Any other things I should check?

Thanks

I think there is a big ground strap on the back of the engine (Might be Z24 I'm thinking of) and they tend to go bad and will cause it to do dumb stuff when it's warmed up. Otherwise I'd be making sure the starter is ground properly.

Today on the way home from work I stopped to get gas and when I went to start the truck it didn't the first time, second time it cranked slow but started. Started fine when I left work.

I think I need to re do the terminal on the large power wire that goes to the starter, the terminal is a little loose.

When I got home I shut it off and tried starting it a few times and it did start but it cranked real slow, and as I said previously the voltage gauge goes all the way down to 8.

I wasn't sure if the battery I have was the sealed type or the type you add water so I looked at a picture I had and it is the type that you can add water.

I added water to all the cells and started the truck. This time it started no problem, this was after the truck sat for about 2 hours.

I grabbed my multi meter and checked voltage at the battery to compare to what the volt gauge was showing, pretty close, more accurate on the meter as it is digital.

This is what I was getting, don't think it's a alternator or battery problem (stock alternator):

Engine running no accessories on 13.98 volts at battery
Engine off nothing on - 13.90 volts at battery
Engine running with high beams on (100 watt bulbs) - 13.78 volts at battery

after all that, when starting engine volt gauge in the truck only went down to about 10 volts and engine started right up, tried starting it 3 times, no problems.

Wonder if the cells being a little low could have caused this? Will find out tomorrow I guess.

Today after work, stopped to get gas, went to start the engine and it cranked really really slow, I was going to turn the key back off for a second but than it started, weird, maybe the starter is on the way out???

Probably the starter solenoid going bad.. In the old days you could buy just the solenoid but now it's the whole starter. You can take it to any part store and get it checked but you have to pull it out. As an electrician I always increase the wire size and make sure the ground is good while at it...Good Luck!

Fanophins 09-05-2015 12:35 PM

By the way if you have a flooded battery your supposed to only add distilled water that you can get at any grocery store. But if you had lead showing on any cell the battery is probably done. But any part store will check a battery for free..

ahardb0dy 09-05-2015 03:26 PM

I would replace the whole starter before just replacing the solenoid, especially if you have to pull the starter anyway.

Thinking of adding a second ground from the starter to the frame, I did that in my former pathfinder when I was having starter issues.

The battery looked slightly low on the water, I could not see any lead. I know it's supposed to be distilled water but didn't have any, used a bottle of bottled water.

I searched online last night and came across a guy with a frontier with a similar problem, someone suggested that he connect the ground from a jumper cable to the negative and the frame to see if it would help, the guy said it did, so in his case at least it must have been a ground issue. May have to try that out.

Thanks

Finally got outside to do something.

Added a 4 gauge ground wire from the lower starter bolt to the engine mount bolt on the frame. Cleaned the negative ground wire terminal at the battery.

Will see if the extra ground helps.

i drive a tractor trailer. in the summer we do not shut the trucks off during our work hours. the starter is a big heat magnet. when the trucks run and run, the starter is soaking in all that heat and then it can take twice to three times the amperage to start a hot semi motor.

carry on gents.

ahardb0dy 09-07-2015 11:30 PM

will see if adding the extra ground helps, thanks

ahardb0dy 09-09-2015 09:36 PM

Extra ground wire did not help. Tomorrow going to check the power wire at the starter end. If it looks OK and is clean and tight, than it may just be time to order a new starter.

The way it is starting when it gets hot sounds like when the Chevy guys would advance the timing and the engine would take a second before it would crank over.

So a little while ago I tested to see which wire goes to the starter solenoid from the starter relay. I disconnected the plug from the relay and jumped the terminal straight from the battery positive and the engine started.

So now that I know this, next time the starter does not crank or cranks slow, I can unplug the one plug from the relay and jump it to the battery, if it cranks normal than either the starter relay or the ignition switch is bad.

I think I will pick up a new starter relay as the one I swapped in a while back was a used one.

Will report back with my findings.

Also determined the wiring to the relay,

black/yellow stripe is positive going into the relay
black/yellow stripe is positive going into the relay
black/pink stripe is output to the solenoid
light green is the ground coming from the clutch interlock switch

I think unlike normal wiring to a relay where the relay has constant power than when you flip a switch the relay allows power to pass through it, the starter relay has power going in on two wires only when the key is turned to the "start" position. Did not have power to the relay unless the key was turned to "start"

black/pink to the positive battery will let the starter crank without the clutch pushed in.

I made sure the trans was in neutral with the key to "ON" when I did this test.

I have a starter for sale man 50 bucks. Bought it 2009 my truck was parked 2012 very little use

ahardb0dy 09-16-2015 08:28 AM

I'm not going to replace the starter unless I find out the starter is the problem, thanks for the offer anyway.

I'd rather put up with the problem for a while and find out what is really causing it than to just start replacing parts that are not the problem.

ahardb0dy 09-21-2015 09:22 PM

Guess it's new starter time ! Today had the truck running for a while than shut it off, went to start it and it was cranking real slow, perfect time to test my theory. Unplugged the one plug at the starter relay that goes down to the solenoid, jumped power from the positive battery terminal to the wire that goes to the solenoid, still cranked slow.

So this tells me the ignition switch and relay are not the problem, leaving the positive wire to the starter or the starter it self.

Hopefully this one won't be as much of a pain in the ass to replace as it is on the V6's !

ahardb0dy 10-03-2015 01:01 AM

Just ordered a new starter (New, none of that reman crap ever again !)

ahardb0dy 10-18-2015 05:17 PM

just installed the new starter, sounds better, will see how it does when I drive it for a while and try to start it, should be good now.

Ludacriss 03-15-2018 08:45 AM

Slow start
 
I have a95 5speed, new alt, new starter not a reman, new ends, new cables. new bat with like 850cca. Slow start, when the engine is cold, slow, no start when it's warm. disconnected the spark, still slow crank, voltage drops from 12-8. all cells are good, clutch safety switch test good, no starter relay clicking and such. retardedthe timing, nothing's changed. so, not a spark issue, not bat, alt, or starter, cable and or end issue. Idk.:hot:

ahardb0dy 03-15-2018 02:32 PM

sounds like the starter is bad, drawing to many amps than when it gets hot won't start.
