Check the distributor. See if the shaft bushings are loose.

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.

Something is draining my battery on my 1998 Cadillac DeVille


I suspect parasitic draw. All vehicles draw some power from the batteries when the car is shut off. Certain accessories such as clocks, radios remote door openers and alarms always need power. The normal power used is called parasitic draw.

It is always a very low draw so it doesn't run the battery down. If you install accessories like shortwave radios or plug things like inverters and portable refrigerators into the accessory socket and operate them too long without the engine running you can drain your batteries to the point where the engine won't start. If there is an electrical short in the vehicle or a malfunctioning accessory it could be drawing much more than its normal load causing a drain on the batteries. If you leave your door open and the inside lights stay on all night you could drain the battery down till the car won't start.

Here's also a good resource for your car specifically on narrowing down the cause of the drain.

My 4 runner starts sometimes and won't other times, it justs cranks over but won't run


As with any no start issue, you will need to check for spark and fuel pressure when it won't start to know how to proceed.

1999 Cadillac some times starts and other times it just cranks and won't start for several weeks


You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a relay, the ignition module, coil, fuel pump, or a list of other things.

2002 Ford Explorer ran out of gas put gas in and won't restart. replaced fuel pump and fuel filter still won't start. Cranks but won't start


Most Fords have a fuel reset button. When you ran out of gas you tripped the circuit. Most of the time the button will be on the passenger side by the kick panel. The exact location should be in your owners manual or your local library or auto parts store will have a copy of one for your specific vehicle.

I started the car after not making sure that the cap was not tight that leads to the water storage compartment. Then the car over heated and the cap busted off. I had to pull over becuase the car slowly...


If you ran out of water and the engine got so hot it seized up....you'll have to wait till the engine is cold, then try starting.

hopefully the engine is not ruined.

Good Luck
