First make sure you have compression on all cylinders if you have compresson on all then you have antoher problem, if it trys to start and back fires you could have a bad distributor cap or a bad set of contacts or the rotor has come loose and is spinning around.

Tahoe not getting fire to plugs, when I try to crank it there is an odor of gas and no start! Crank sensor,evap purge valve solenoid, fuel pump and knock sensors have all been replaced.


Things to check:
  1. Timing chain or timing belt (depending on which engine you have);
  2. Coil pack or ignition coil (depending on which engine and year);
  3. Rotor and distributor cap (if your Tahoe is an earlier model);
  4. ECU (especially if you jump-started the car before the issue began);

JUST DID A HEADGASKET JOB ON MY 95 SUBARU LEGACY, GET EVERYTHING BACK TOGETHER NO SPARK?


sounds like a timing problem, did you replace the cambelt? or check the idlers for wear? a worn idler could make it jump.

I have a 04 sebring with the 2.4 dohc it started running bad and coded random cyl misfire and ignition ckt b malfunction i changed the wires plugs coil pack timing belt crank and cam sensors still no go...


Random has to universal problem. Think timing belt or fuel or air. All cause random. Get timing marks and check timing. Use fuel pressure gauge to look for constant even fuel pressure at 40 psi even with key off. Listen for loud sucking sound and try find where it is coming from. These things will help if electrical Ctrl issue exists must take to qualified technirian.

TURNING OVER BUT WONT START REPLACED COIL PACK, FUELPUMP, FUEL FILTER, PLUGS AND WIRES. CANT FIGURE OUT THE PROBLEM


Have you checked the injector wiring? Each has only 2 wires you can check. If no power, test the injector power control module.

My truck is missing on the forth and fifth


things that can cause it to miss.
fouled plug (checked)
bad wires(checked)
coil pack(checked)
ignition signal to coil pack( switch old coil pack to a working cylinder to make sure its good and you may find a possible short in the wiring to the coil pack) alternately check the voltage to the wires going to the coils make sure like colors have like voltages. im not too big into ford trucks but thats a good start for most vehicles
possibly injector stuck open and flooding cylinders
timing could be off

Truck not firing properly front coil pack not firing at all.


if this truck has an o2 sensor i would replace that and also make sure the cat-converter is not plugged,this would give you your powerloss and egr code,next is your coil,this may be caused by the computer or your crank sensor,look at the tone ring that the crank sensor uses and make sure its not missing teeth or broken,also check all your fuses.

Changed timing belt on my 99 ford escort zx2 car no


if you have a no spark scenario i would check your crank sensor located at the top left side of the harmonic balance pulley.the crankshaft (about 11'oclock) a 2 wire plug with a sensor on it check to see if it is damaged or unsecured. this sensor can cause no spark if not working correctly. This sensor is based of frequency not voltage testing is difficult, just make sure that there isnt too muck air gap. and that it is secured.Lastly may want to check timing possible that the belt has jumped some teeth and she has fallen out of timing. maybe a bad tensioner The coil will adapt i think up to 10 degree, ****** or advance. Good luck

1994 honda accord won't start and has no spark


Check your coil and ignition module and ignition module fuse. this is a primary ignition problem for sure. check the primary resistance side of the coil it should be between 1 and 3 ohms. Also are you sure you put your cam gear at the exact mark it shoul be at and not 180 degrees off, otherwise car won't start.
