1996 Nissan Pickup-Replaced all drive belts, now it won't start Sign In

My drive belts have been getting pretty frayed and cracked for a while, and I finally got around to replacing all three of them this weekend. Having finished this, my truck now refuses to start. I have double and triple checked all the belts, and they are all in the correct locations. I didn't touch any other part of the engine.

When I try to start it, the engine chugs a bit, and refuses to turn over. It gives off a faint smell of gas immediately afterward. The battery is charged and working, and for clarification, everything functioned perfectly before hand. Any help or advice would be immensely appreciated.

There's something being missed that isn't clear yet. Just how do you know battery is charged and fine? Did you use a tensioner tool to adjust belt tension? Hmmm, you are just guessing aren't you?
Does this have a hood light that stayed on while you did this? Doesn't really take all that long to lower the charge of a battery such that it wouldn't crank fast enough to start up if that's what you mean by "chugs a bit?"


Other: It's possible that you have a bad pulley and in the course of tightening the belts it now failed and locked up. Yes a strong belt and locked up pulley could prevent engine from cranking. If that's possible at all loosen up belts and check and take them all off and try to start it for a few seconds then find which pulley is causing the problem,

Thank you so much for the response! The battery was tested with a battery and alternator tester. My hood light doesn't come on automatically, it has to be pressed on, so that shouldn't be the source of the issue. A tensioner tool was not used, but I tightened them to Chilton's recommendations. Not guessing, just acting to the best of my rather limited resources.

It is a possibility that a pulley may be bad. I had to replace one of my adjustment bolts, and my bottom idler pulley was removed in that process. I just loosened all my belts and tried starting it again at your recommendation, but didn't have any luck. Its getting dark out, so I was unable to remove the belts and test that, but it's the first thing I'll try tomorrow.

As for the "chugging", it cranks, and then shudders some, but fails to start. My apologies for the imprecision. If there's any other information I can provide please let me know, and I'd welcome any further advice.

Let it be for now but you don't know how powerful your battery is in AMPs. You could by just watching voltage drop while cranking never dropping below about 10V would be great if the rest was normal.


What probably happened is a weak pulley gave out and locked up. Old belts just let it be till new ones probably tight which you do when new and recheck in even 15 minutes and again after a day's use.


Non self tensioned belts most likely and by bolt thru another that you loosen and lock is easy to overtighten which is fine for while working but just might have killed a weal bearing of a pulley and might even seen one a bit crooked?


That's why I suggest you take them off or just loosen a suspect one of the three you said and see if it will run. IDK - could also soap up the belts so they would slip for a while too or with water - but one almost must have locked from the job.


If you have a helper let someone else crank the engine you may see the problem live and watching may be obvious?


IDK - did alternator tip out of place and short out or any other issues while replacing belts?


The coincidence is just way too out of the question so it had to be something broke or went wrong with a pulley or belt wildly way too tight caused a problem?
