95 dodge caravan with 3.o engine won't start??????

Are you saying the engine will not crank, or crank but will not start ?
None of the engine sensors come into play until after the engine is cranking.
Cranking problems can include the neutral safety switch and other factors with the crank circuit back to the key switch.

No they won,t.

try checking the crank shaft sensor, i had that problem with a 95 cirrus

Car no start problem is sometimes very difficult to confirm. You try all the possible things, but still you get no fault and problem is still the same.--------
In that case, you need to check few things individually.
Check the spark,the battery,the crank, the fuel and other most possible parts. Click this link below for more details:-- http://howtobyme.blogspot.com/2011/10/car-troubleshooting-tips.html

Hi!

I would say its a Battery problem, Which has no strength to start the engine with the other electronics on. Have your battery check if this problem just started. Good luck

The 95 Caravan is great for giving you trouble codes. However they are two digit codes. There should be a blink sequence followed by a short pause then another blink sequence (example 2 blinks, short pause, 3 blinks... Then 5 blinks, pause, 5 blinks which means no more codes. Turn key from off to run three times and leave in run and watch check engine light to count blinks. Disconnecting negative terminal on battery for 30 seconds clears codes.

That is a code for the secondary (spark) circuit on cylinder number 3. It is usually caused by a bad connection between the coil and the plug (take the coil off the plug and check for moisture in the boot). If not, it might be a bad coil...

Turn the crank pulley make sure the engine is not siezed

a i got a 1996 with the 3.8 dodge caravan and the codes red 12 and 55 my car wont start at all got gas in it

Here is a link to the possible things that cause a check engine light.
These are GM but 95% are generic to all cars and light trucks no matter who makes them.
