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.

92 Toyota 4runner truck was running perfectly fine Later in the day went to start and the alarm just started going off and wouldn't turn off. Truck won't start even with keys turned in igniti


The alarm system somehow got activated , this is usually because the battery becomes discharged or disconnected try doing this:
Remove the key from the ignition
disconnect the negative battery terminal
put the key back in and turn to ON
exit the truck and leave door open
reconnect the battery terminal
get in and leave door open, if the alarm horn stays off it should start.

I HAVE A 1994 Chevy Truck G 20 Van V8-350 5.7L ...CRANK NO START I AM GETTING FUEL TO THROTTLE BODY BUT not injection into motor. being test wires all day first the fuel pump wouldn't prime so had a...


If the fuel pump does not prime either the PCM is not sending a ground signal to the relay, the relay is bad, or there is an issue with its circuit (no power to relay/blown fuse, short in wires).
Your injectors not spraying may be the ignition module. The module sends a signal to the PCM to let the PCM know the engine is turning and running. If the PCM does not see this signal it may think the engine is not running and when it does not run it does not spray fuel.
Take the module to an autozone to have it tested.

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.

sounds like you have no power(12v) going to the alternator.verify the single red wire @ alternator
has 12v. if there is no power you'll need to trace the wiring,.start by checking fuses in cab & in the
engine compartment fuse boxes

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.
