I would recommend you replace the ignition module.

SOURCE: okay, thanks for reply earlier...here's more info...maybe you can help

the valve cover seals like to leak and fill up the spark plug tubes with oil. so 1st thing, you should pull the spark plug boots to check, the pull and inspect the spark plugs.

next.
pull spark plug boot off of the #1 spark plug. Insert a new spark plug into the spark plug boot. Ground the plug to the engine.
Crank the engine and look for spark across the electrodes of the spark plug.

then reconnect the boot the the #1 plug, pull the boot off of the #2 plug repeat the test, then do #3 and #4.

if all cylinders have no spark/ weak spark, its most likely a bad coil pack.

to check the coil pack:
Measure the primary resistance of each coil. At the coil, connect an ohmmeter between the B+ pin and the pin corresponding to the cylinders in question. Resistance should be 0.45 - 0.65 ohm.

----------------------------------
Measure the secondary resistance of the coil between the towers of each individual coil. Secondary resistance should be
11k - 14k ohms

you have a bad crankshaft sensor. replace the crank sensor.

dodges and gm's are known for this problem.

When changing the timing belt you need to place the cam shaft a TDC( clock wise), then rotate the crankshaft to TDC (clockwise), then back off the crankshaft (counter clockwise) THREE TEETH then back (clockwise) 1/2 tooth before TDC place your timing belt arround the crankshaft- water pump- and camshaft finally putting arround the tensioner pulley, holding 25 flbs of torque on the tensioner pulley to get the correct tension then push up on the hydrolic tensioner and tighten and you should have it.... rotate the crankshaft twice, if the camshaft pulley ends back on TDC then you have it correct.

I have a Ford Expedition XLT with a crank no start I changed the fuel pump and check all the fuses can somebody else tell me what may be the problem


A "crank, no start" condition is usually because either gas or spark has been lost. You changed the pump, but now you need to verify that gas at the proper pressure is at the engine's fuel rail. You would need a fuel pressure gauge tester for that- Autozone and others loan them, too. Or, do you hear the pump turn on with the key cycled to on, not start? It should turn on for 2 seconds to pressurize the fuel lines and the fuel rail. If it turns on, probably at proper pressure since you have a new pump, but never hurts to check the pressure. If it doesn't turn on for those 2 seconds with key in ON, then you will have to diagnose the fuel pump circuit. Post back for that.
Next thing to check is spark. Buy a simple spark tester at the parts store (real cheap) and hook it up to a spark plug wire, crank the engine over, and watch for a strong blue spark. Good idea to check more than just one plug wire-sometimes a bad coil will lose spark at a particular cylinder. If you have good spark (a blue, snapping spark), then assume the ignition system is good, and so then you would need to verify the injectors are putting gas into the cylinders-post back if you need to test the injector circuit.
If no spark, then the ignition system has a failure-this can be from a bad Ignition Control Module, a bad crank position sensor, or cam position sensor, among other things. Good luck.

1998 Mitsubishi spider 2.4 spark plug and Coil want wiring diagram


Your engine uses a "waste spark" ignition, meaning it uses one coil for each pair of cylinders. The high voltage current path is to the first spark plug, through the aluminum cylinder head to the secodn spark plug, then out of that plug back to the ingnition coil. One plug fires on the comrpession stroke and the other on the exhaust stroke to ignite any unburned exhaust gasses. The engine's computer "fires one coil at a time based on signals from the crank angle sensor and the cam angle sensor. Likely the problem with your engine is with one of those two sensors.

An OBDII scanner will indicate which sensor is defective. If the engine ran fine before you turned it off, and now it will not start, the problem is likely the crank angle sensor (close tot he crank pully). Otherwsie, oif the engine starts sometimes and not others, it is due to a defective cam angle sensor (near the intake cam "gear" (where the timing belt cover is).

Honda will not start it is not battery


what engine, see list at end. 2.2L 2.7L or 3.0L?
never post no starts, with no engine stated, all below is GENERIC HONDA.
you are guessing why guess?
how did yo prove its not the battery.?? jumper cables starts?
how? never tell the mech, that, let him find the truth.
if you tell him wrong, he may spend a fortune proving you wrong.
(not me but can) see why? (labor and wrong parts replaced)
is this a no crank >? or a no start, why start at step 3.
or even not tell step 1 &2 ? was done.....

all use old folks , have hand cranked old tin lizzys.
and owned 50 motorcycles all FOOT KICK started.
so if it dont crank robustly it will never start is not lost on the old crowd.

  1. checked all fuses yet? CEL lamp glows in dash KEY ON??????
  2. cranks fast?
  3. got spark?
  4. ever done the 60k miles tune up, and is the CAM belt fresh.
if the cam belt snaps, the whole engine can be lost.
i do leak down tests on all hondas. for good reason.
and 100x time that for Honda's NEVER SERVICED !!!
i can even hear you crank it, and see its lost compression just buy the sound of the starter, (sounds like sewing machine running, no load)

if compression is good and spark is good, and not flooding
you can use test fuel, to prove engine and spark is good.
but id not, if that cam belt is not fresh.
you never posted engine type ,size or cyl count so can be accurate here.
my 1st rule on honda's (all interference engines)
is: RULE1: First do no harm.
and cranking it like mad, is just that.


see belt change intervals. USA miles.
did you replace it? ever?
Honda belts, fleabay $10 belts will never last this long, ever....!!!!!

Buy Gates belts or Honda real.

OK: ILL pretend engine compression is good
cranks fast
spark is bad. (on all cyl)
connect (in USA) the scan tool and crank for 5 seconds
id bet the ECU just told you (by RPM=0 , or DTC why it dont start)

My 1998 plymouth neon has a number 4 cylinder misfire. changed plugs, wires, coil pack. still misfires. does it at slow speeds and really bad when trying to get up to speed when entering the highway....


CHECK FUEL INJECTOR WIRING TO NUMBER 4 INJECTOR,HOOK A TEST LIGHT TO MAKE SURE IT BLINKS WHILE ENGINE RUNNING.THAT WAY YOU WILL KNOW IF PCM FIRING THE FUEL INJECTOR OR FAULT AT THE INJECTOR WIRING OR YOU HAVE INTAKE LEAK LOW COMPRESSION TO THAT CYLINDER BECAUSE OF BAD BURNED OUT VALVE.COMPRESSION TEST TO THAT CYLINDER CAN ALSO HELP.LOOK FOR LOOSE OR WORN DAMAGE ROCKER ARMS IF YOU HAVE A SOHC SINGLE OVER HEAD CAM ENGINE.

YOU NEED TO CHECK DARK GREEN/ORANGE WIRE AT IGNITION COIL WHEN CRANKING ENGINE FOR POWER..IF NO POWER,SHUTDOWN RELAY IS NOT BEING ENERGIZED..THIS ENGINE ALSO HAS CAMSHAFT POSITION SENSOR ON END OF CYLINDER HEAD..ENGINE CONTROLLER NEEDS CAM AND CRANK SIGNALS TO ENERGIZE THE SHUTDOWN RELAY..UNPLUG CRANK SENSOR AND CHECK VOLTAGE ON ORANGE WIRE..SHOULD HAVE APPROX 8V..IF NOT..UNPLUG CAM SENSOR AND SEE IF 8V SUPPLY RETURNS..IF NO POWER TRY UNPLUGGING VEHICLE SPEED SENSOR LOCATED IN TRANS HOUSING WHERE RIGHT SIDE AXLE COMES OUT OF TRANS..IF 8V RETURNS..THE SPEED SENSOR IS SHORTED INTERNALLY..THESE 3 SENSORS SHARE THE SAME 8V SUPPLY CIRCUIT..WITH SPEED SENSOR UNPLUGGED,PLUG CRANK SENSOR BACK IN AND TRY TO START ENGINE..HAVE SEEN THIS SAME PROBLEM AT WORK RECENTLY
