1999 eclipse gs wont start but will crank over

Have you disconnected the negative side of the battery, leave it off for 15 to 20 minutes, then reattach the negatives. Or, you should be able to just leave the key on for 20 minutes and we'll light should go off. Did this just start happening? Is it a new key?

Engine cranks over three times an stops ? starter or battery cables . does it crank over slow ? Save yourself some money an take it to a ASE certified repair facility !

Check all battery cable connections, including where (negative) attached to frame or engine block. Won't hurt to check wire connector to alternator as well and use voltmeter to check charging system out-put.

first make sure battery is charged if so then then check the relay in the fuse box under the hood find the relay that marked "ing" pull that relay then find a nother one to inter change with it, if car still wont start then ou will need to see if the in line fuse on the starter wire is good or blown if its good then you will need to pull the starter and replace it. hope this helps you

fuseable link beside battery its probably blown

Since the engine cranks, the battery, starter motor/starter motor solenoid are most likely
good, so suspect everything else on the list. When you narrow it down, re-post with a
more specific question about that particular component, since 100s of components must operate
nearly perfectly for a vehicle to actually start.

Sounds like a failed or disconnected ignition coil wire.
Hook up an OBD reader and crank the thing for awhile watch the reader for the code. Look up the code number . You may need a book for your car to do this. The reader will tell you what's amiss.

it sounds like the problem but the question is why wont the pcm start the car. with the key turned to on the service engine light sould be on. if not the pcm has no power.

Along with the solution provided above be sure to hook up the positive cable Red to the positive cable on the car to be jumped and the car used to jump the battery both cars off. Next on the car with the dead battery hook up the negative cable to the frame of the car if it is a liquid or lead acid battery, next hook up the negative cable to the car that will jump the other dead car. Warning an arc can cause an explosion if there is gas coming from either battery so when hooking up the negative cable be sure to clamp the negative cable on the frame. Next start the car and rev it to about 800 RPMs hold it to 800 RPMS for about 5 minute's before try starting the other car, this will allow the other battery to charge up and will help start the car. If you have small jumper cables like #6 copper give it about ten minutes to charge before try starting or you could damage the alternator of the charging car. once the time has elapsed try starting the other car, push throttle down once while cranking it over and hold pedal half way till it starts, do not crank for more than 30 seconds if it does not start wait for the battery to charge up again to try starting. with low voltage condition if you crank the car and it slows down it can damage the computer by drawing to much amperage caused by low voltage.
