Engine cranks for about 1 minute to start...once started it will start 1st time all day until a very long period has elapsed usually the next day.


It takes 20 minutes of driving to put back into your battery what charge it took to start the engine in the first place.
If you start the engine 3 times in a day then you would need an hour of driving to recharge the battery. Check your voltage on the battery the next day with a voltmeter, You need at least 12.6v.
Check for a battery trickle leak.You will have to remove each fuse in turn until you find the cause.
Cranking for a whole minute is unhealthy for the battery and there is obviously an underlying fault in the starting system. I would also check the fuel pressure at the port and get a cylinder pressure test

Auto Zone does not test the alternator under full load so the test result could be borderline.
start the car and turn everything on. If the voltage drops lower than 14.2
replace the alternator.
also the battery could be being drained overnight. to check use a test light by removing a battery terminal and connecting light between battery and cable with car off.
if it lights start be removing fuses.
when the light goes off the problem is with this circuit.
lastly if the light stays on take the wires off the alternator.
if the light goes out replace alternator.

Interior Dash Lights dim, brake & battery warning lights flash on and off.


Sounds like your alternater, get a multimeter set it to volts start the car then check the battery is getting 14 or over volts from the alternater to the battery , if your getting less than that it's not putting enough volts back to the battery to run the car with good luck colin

Just had plugs,wires and bottom gasket leak fixed. Car cranked next day,several hrs. later,wouldn't start.mechanic came and jumped it off,said alternator was getting too hot. Next day cranked, drove to...


That would make sense, because when he jumped your car if he left it hooked up for awhile. Then he charged your battery up, so it started the next day. Then you drove to his shop and back it ran the battery down. It's easy enough to test and change alternators you could take it to autozone or O'Reillys if there is one close they can test your alternator. If you have more questions about this or if you would like to try and change it yourself just reply to this post and I will walk you through it.

Driving down road truck cuts off


I had the same thing happen in my 1985 Nissan Pickup. It would just cut off. It was the fuel pump regulator switch on my vehicle. About a $50 item from autozone.
