You may have got the oil switch wet and it iscauseing the fuel pump not to work to test turn the key to the run postion (Not Start) listen to see if you here the fuelpump comes on for two seconds. does it? if yest then pull a plug wire and put in a screw driver in the wire and get it 1/4 away from ground then crank engine over do you get a blue spark? if yes you have water in the fuse box or in the crank or cam sesnor and you will need to buy a can of compressed air to blow them dry. Let me know if you need more help and thanks for using fix-ya.

Crank, won't start problem. I checked the spark plugs on Jeep 98. Looks good. Could it be the crank sensor or starter coil?


Yes it is very much possible.But there are many other possibilities too,including starter and spark plugs issue.

If your engine cranks normally but will not start because it has no spark, or it stalls and won't restart because it has no spark.

You can also do a test to confirm the problem .The procedure to do the test is as follows:---

If your engine has spark plug wires, disconnect one of the plug wires from a spark plug and place the end of the wire near a metal surface on the engine. Then insert a small Phillips screwdriver into the end of the wire (the plug boot), or a small bolt or nail to provide a conductive path. Then crank the engine and look for a spark to jump from the screwdriver, bolt or nail in the end of the plug wire to the engine. If you do not see a spark, there is an ignition problem.

OR-----------

If your engine has a coil-on-plug ignition system with no plug wires, In that case remove one of the coils from the spark plug and insert an old spark plug, a spark plug tester or a screwdriver into the end of the coil. Ground the spark plug or plug tester to the engine, then crank the engine and look for a spark. No spark indicates an ignition problem.If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If NO voltage, then problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).

But If there is NO voltage at the coil itself, then in that case the problem is on the supply side (the ignition switch or ignition wiring circuit).-----------------

Jeep cranks but no start:----------------

A jeep that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the jeep. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the jeep. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the jeep. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the jeep. If the car starts momentarily, then there's a good chance the fuel pump is not working or the jeep is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks. Helpmech.

My 2000 jimmy stop running. i have fuel presure, spark plug wires have spark. I replace both crank, cam, ignition modual sensor and the ecu. Also took of the mufler tinking it may be plug. Engine turns...


yeah, check the order of the spark plug wires on the distributor cap. Perhaps they might be mixed up not allowing it to run properly and yes, even sometimes stall. check that first if not, then check to see if you are getting fuel at the engine. If not then perhaps its a bad fuel pump...good luck!

1995 dodge dakota 2wd 3.9 no spark to plugs,or coil,orfuelpump


First of all let's explain how the spark gets to the plugs. There is a crankshaft position sensor and a cam sensor. They are what determines when to fire the coils and injectors. The crank sensor is located on the passenger side on top of the bellhousing, the cam sensor is the pickup plate in the distributor. As the engin turns the send refernece pulses to the computer which grounds and ungrounds the ignition coil causing it to discharge and send voltager from the secondary coil wire to the center tower in the distributor cap. The rotor button recieves the voltage and distributes it to the 6 towers (1 for each cylinder) If you say you're getting spark from the rotor that tells me the primary side of the ignition system is working, and the secondary side is working into the distributor cap. I'd check for spark out of the plug wires at the plugs. Pull a wire and insert a #2 phillips screwdriver into it, hol the shaft of the screwdriver aprox 1/8"(no more) from the exaust manifold and observe the spark as someone turns over the engine. You should see a nice blue spark. If theres spark, spray a little gum cutter in the throttle body an crank it, if it fires you have a fuel problem. Install a fuel pressure gauge on the schrader valve on the fuel rail and observe it as you crank it. If theres no fuel pressure maks sure there's fuel in the tank, if so climb underneath and beat on the bottom of the tank with a rubber hammer, the pump may be going bad, sometimes you can jar them and make them run.
