Did you plug the connector in when you installed the new pump?

    why was this marked inappropriate? It was a serious question. I cant tell you how many times I have seen someone leave the connector unplugged. Sorry if you took that the wrong way

I have a 2002 dodge intrepid cranks but no spark.changed cam shaft sensor and crank sensor., all new plugs but still no spark....please help ..thanks


Hi Leroy, Im glad to help!

Here's a couple things you can try. First, swap the ASD Relay with one of the same type relays in the relay box. If it still doesn't start check every fuse. If it still doesn't start check power and ground at the "COIL PACK" If power and ground are good Replace the Coils Pack. If there is no power and ground at the coil pack then make certain you are getting power from the ignition switch to the ASD Relay. Hope this helps and have an awesome day Leroy.

89 Comanche 4.0 inline 6cyl no power to pump and now no spark as well?


I'll try to help you, John.
For spark: If your spark plugs, spark plug wires, dist. cap, and rotor are good, check the coil. Take off the negative battery cable. Use an ohmmeter and check resistance between the coil primary positive terminal and the frame of the coil-ohmmeter should show infinite resistance, if not, replace coil. Put ohmmeter positive lead on coil primary positive terminal, and ohmmeter negative lead on coil primary negative terminal-resistance should be zero or nearly zero, if not, replace coil. Connect ohmmeter negative lead to the negative primary terminal and ohmmeter positive lead to the high voltage terminal of the coil. Ohmmeter should not show infinite resistance, if it does, replace coil.
If coil is good (or has been swapped), check that coil primary has power to it with key on. If it does, and no spark, the problem could be the ignition module or the pickup coil. The ignition module should be mounted with the ignition coil. The pickup coil is inside the distributor-this pickup coil is what tells the computer (ecu) the crankshaft position, so is critical for spark timing.

For the pump: the fuel pump relay is in the power distribution box under the hood. When the ignition switch's run wire energizes the relay's coil, power is sent to the pump. You could check for a signal on the pump wire at the tank, with the engine cranking Should be a steady signal then. If not, pull the relay out to check that the power feed for the pump is still there. The power to the relay comes from Fuse link G, a 20 amp rated green fuse link. It is hot at all times, so check for a power signal on one of the relay terminals with key off. One terminal should have power. If not, check fuse link G. If it does have power, put relay back in and have someone cycle the key-relay should click-may feel or hear it. If nothing, try a different relay. If relay was good, but no power to pump, pull relay and check terminals that relay plugs into: with key held in crank, two terminals at relay should have power-the power feed from fuse link G, and now the ignition switch signal to the relay coil side. If all checks out, probably a bad pump. If you checked for power at the tank with the engine cranking, and did have power, that is for sure a pump that needs replacing.
Good luck.

My car will not start it cranks but will not turn on. So far I have changed the crank sensor I also have no spark to coil packs or spark plugs Fuel pump does not turn on when I turn the key. What is the...


Begin by checking fuses. Ignition, efi, fuel pump fuses. When key turned to on, do the warning lights and gauges work? That verifies switch has power and is sending power out. With key on, the coil primary wire to coil packs should have voltage.

No spark and no gas? Fuel pump fuse good? I think I would use a test light or multimeter to check that fuel pump fuse terminal has power to it with key on. If that's good, pull connector off at fuel tank and check for a voltage signal on fuel pump wire when the engine is cranking-if good signal, fuel pump needs taken out for replacement or inspection. If no signal check that fuel pump relay has power to it. With key off, pull the relay and check that one terminal has power to it-the feed wire for the pump. If no power signal at all, check maxi fuses or fusible links for a failure.

Have a 1999 ford explorer sport 4x4, cranks want start. have replaced fuel pump, crank senser and cam senser, checked fuzes, replaced computer. doesnt seem to be firing


When you turn the key on you should beable to hear the fuel pump come on. Other than that you have a fuel pressure test port, looks just like a tire valve stem get a little probe press the valve after cranking fuel should come out strongly and not dribble out. If is doesnt seem to be firing your going to have check the coil pack for spark from the coil pack take one plug wire out and put it in a position that as you crank the vehicle you will be able to see spark jump or even hear give it a 1/4 air gap from its connection. If you dont have spark and your timing chain isnt broken you need to check for power the choice of tool is a test light.or volt meter. If you dont have either test tool we will go by sound when you turn the key on the engine fuse box has relays do you hear them click. That click noise will be fuel pump relay and PCM relay for power inpect those relays for corrode connections you mainly have a power problem and inspect for proper ground a missing ground can also cause the ECM to not fire the coils2_26_2012_7_32_43_am.gif

Car mont start. does not turn over


You need to find out if the problem is related to spark, fuel, or air. First thing - when you turn the key to full electrical power (right before you crank the engine), do you hear the fuel pump kick on? It's a slight whirring sound behind you, and lasts about two seconds. If not, check the fuel pump relay (blue relay in the driver's kickpanel), and check the fusebox to be sure the fuse isn't blown.

If you hear the pump come on, chances are the rest of your fuel system is probably OK (the Z isn't known for common failures of the fuel pressure regulator or leaking injector O-rings). Time to turn to the spark side of the equation.

Unbolt a coilpack (look between the runners of the intake manifold and remove the two 12mm bolts you see, which secure a bracket - that's the coil pack bracket). Pull the coil pack out and remove the spark plug. Put the plug into the coil pack, make sure the coil pack connector is plugged in, and have someone crank the key for just a second, while you hold the coil pack with the spark plug ground touching the manifold. If you have spark, you'll see it flash. If you don't see a spark, there's a very good chance that the power transistor unit (PTU) is dead. This was the one and only recall on the Z32. It's a small black box on the front of the engine, passenger side, bolted to the upper timing cover. It has a 6-7 wire harness coming into one side, and going out the other side. If it dies, your car won't start until it's replaced.

If neither spark nor fuel is the problem, then clean or replace the mass airflow sensor. Also, have the cam position sensor checked (this is the round metal device on the driver's side timing belt cover) - that thing is the root of all Z evil and can cause many different problems with these cars.
