    That sounds like one of the fuel injectors is faulty, and the ohm's should be checked on all of the fuel injectors. A fuel injector that is out of ohm's range will affect the entire fuel injector system, especially if the fuel injectors are gang fired and with your vehicle they should be, and if one fuel injector is out of ohm range then it will affect the way that all of the other fuel injectors fire, and it will wreak havoc on the entire fuel injector system. You should obtain the ohm specifications for your vehicle and check all of the fuel injectors to be certain that they are all within the specified ohm readings. They should be measured using an ohm meter with the wire connector to the fuel injector dis-connected.

How good is the spark on this cylinder compared to others. Check the high tension lead and plug socket for any sign of shorting. Check out the lead resistance as compared to the others. If everything checks out and you have multiple coils sets try swapping them around to see if the problem follows a coil set.

Number 6 of a 3.0 does not fire changed plugs, wires, cap, and rotor.No change. Then changed #6 fuel injector still no better. It also consumes more gas than usual.


So to backtrack, did you check for compression on that cylinder, spark for the cylinder, and injector pulse before you replaced the parts ?

I have a Mitsubishi gallant cylinder number 1 not firing but spark plug is firing engine misfire,engine check comes on for it to start and it has a hard start help.


If you have spark, but no fire, then check injector for proper activation. If good, check compression. If injector good, and compression bad, possible head gasket, valve, piston, etc.

if you have spark at the plug on #2 then check the injector for voltage and ground you may have a bad injector or plugged or dirty injector. it could also be a vacuum leak at the intake were it meets the head at cyl#2.

Hesitation when excelarating while driving


Check compression in #1. A cylinder needs gas, spark, and compression to fire. Check spark with a calibrated spark tester. It could be an injector problem, so check for pulsing of the injector. Does the spark plug show wetness after being cranked over?
The compression in #1 should be within 75-80% of the highest reading cylinder.

1997 Jeep Cheerokee does not have fire to spark plugs


Have you checked the injector harness for a proper injector pulse? The ECM pulses the ground circuit to fire these and if there is a short in that ground wire the injector will stay open all of the time, effectively flooding that cylinder.


If it has spark, fuel, and even compression, it has to have integrity with the valve train. If you can pull the valve cover off, turn the engine over by hand to make sure that the vales appear to fully open. You can compare them to the other cylinders. It could have a flat lobe on the cam. A compression test wouldn't necessarily pick that up because the cylinder would still compress whatever air is still in it.


Hope this helps.

1991 4.3L GMC Jimmy S-15 will not start. Turns over, but does not start. Replace spark plugs and wires, ignition coil, module checked good. The plugs are gettin fire but not sending it to the motor?


You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 13-13.5 lbs on your TBI
If you have all 3 then move on to injector pulse to both injectors.

Keep me posted and recheck your spark plug wire to make sure they are not crossed. firing order 1-2-3-4-5-6 cylinder # passenger side 1-3-5 front to back. cylinder # drivers side 2-4-6 front to back
distributor #1 is located at the 7 o"clock and rotates clock wise so next distributor post on the right working clock wise is #2. Good luck and hope this helps.

Ce lights on code reads #3 cylinder misfire


I assume this 'complete' tune up was plugs, wires and plennum (intake surge tank) gasket?
If so, recommend you first check to see if you are getting an injector pulse to the #3 injector (a noid light is normally used to verify the injector is receiving the 'pulse' from the ECM. The noid light is a very useful tool in finding out if you have problems with your fuel injector. It is cheap (around 10 dollars per piece), easy to use (if the light blinks, your injector is receiving the electrical pulse to open). If after you verify the injector pulse is present, the next step is to determine if the injector or cylinder is the problem. A simple verification process requires swapping the #3 injector with another to see if the misfire moves to the swapped cylinder.(.i.e, move #3 injector to #2 cylinder & the #2 injector to #3 cylinder.).. Then run engine to see if the P0303 changes to P0302. This would VERIFY the injector is in some way defective. If the misfire STAYS at #3 cylinder, you'll want to perform a compression test of all the cylinders. If after this test you find #3 cylinder is more than 10% lower than all the other cylinders, do a 'Leak-Down' test to determine if the low compression is due to leaky valves (intake or exhaust) or whether the piston/rings are the problem. NOTE: If all the cylinders are withing 10% of each other during the compression test, the possible causes are, injector O-ring leak, vacuum leak at the intake manifold at #3 cylinder, or the spark plug not firing under compression.

Miss fire coil number 8 and coil A


Did you replace the boot that connected to the coil the touches the spark plug. If you didn't then the boot could be bad and instead of the park always going to the spark plug it hits outside the boot on the head. Good Luck
