Ok, first check the hot wire coming into the distributor to make sure you have a full 12 to 13 volts. If you do then I recomend that you replace the rotor and distributor cap first. Let me know.
Good luck. Dont forget to rate.

My 1999 dodge durango 4x4 will turn over but it wont start where should i start?


If vehicle has spark ( even weak spark ) with a fuel supply it should start or at least try to start. Possible fuel pump problem. You need to determine if there is a fuel supply. You can try banging on the fuel tank with a blunt object ( hammer ) while trying to start the vehicle. If it starts or tries to start, suspect a fuel pump failure.If no luck using this procedure, you will need to tap into a fuel line to determine if fuel supply is present and at the proper pressure and volume

Check your ignition coil. Could be the cause. Also check crank and camshaft sensors with a scope to see if you have a uniform pulses. I hope it helps.

Starter wont turn flywheel


starter motor weak. weak battery or engine is seized. take the spark plugs out and turn engine over with spanner on the bottom bolt on the pulley. if thats fine and move the engine freely then check the battery try a jump off a good battery. if not good and still will not start with the spark plugs back in then the starter motor is weak and needs changing. can do any of these in any order you like.

My van just died 1 day after work. it's getting spark and fuel but wont start. i already replaced the crank sensor and it still wont start. please help me?!!!!!!!!!!


the first thing is check your fuel pressure for the right psi. some vehicles will not start if the pressure is off only by a couple psi. your particular van is epuipped with a injector module assembly under the upper intake manifold. commonly called a injector spider. those are notorious for leaking and will keep a vehicle from starting. also while your checking your spark how did you do it? if the spark was any color but blue it is too weak of a spark and the vehicle will not start with that. this could be worn plugs, wires or weak coil.

96 nissan 200sx started and ran rough for 10 sec then died and wont restart. distributor is turning. no fault codes. has good fuel pressure. spark looked weak so i changed cap and rotor. still wont start....


something to ponder over here as iam not sure what could be the problem here but if its a weak spark then it could be module /coil/crank sensor in that order .These problems will not show up as fault codes i dont think as they are working but not to full efficiency

My 1993 jeep wont start it cranks over . There


Most likely crank angle sensor if no spark at all, or a coil problem if very weak spark.

Wont start, weak spark on the spark plugs


You should check your leads. if they are silicone a slight bend can break them and you will have a very weak spark. Also check the gap on the spark plugs, if the gap is too small there wont be a very good spark. If those are all ok check the coil pack(s), they may need replacing.
