Spark plug blew out now car wont start


sounds like the autoshutoff relay may be bad..it controls the ingition and the fuel pump too..if the pump works check for spark by inserting a screwdriver into a pulled off spark plug wire and look for a decent spark between the screwdriver shaft and any ground like the block..if no spark the relay may not be powering up the ignition system..

fuel filter or a fuel pump could also be plugs, wires, cap and rotor I would try fuel filter first then take a plug off a cylinder and hold it close to screw driver or something(dont hold unless have rubber to grip to please dont get shocked) if it doesnt spark your not getting spark and try plugs wires cap and rotor if it does spark then open gas lid have someone turn ignition switch on and listen if you here the fuel pump is still good if not replace it. It does sound like a fuel pump

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

I have a 1996 eagle vision that is struggling to turn on. the battery is new, the spark plugs have been replaced,and so has the module (coil). i dont see elctricity coming out of the spark plugs nor do i...


You meant to say "hear the fuel pump turn on", not the fuel filter. The filter is just that...a filter. No mechanical parts in it. Anyways, if you didn't hear the fuel pump turn on, that means it's not getting power. This is either an electrical problem, or the fuel pump is dead, jim.
You can confirm that it is the fuel pump by spraying gas inside the intake plenum (where it sucks in air). Don't spray too much, doing this is dangerous. In fact I'd recommend a shop perform this diagnostic procedure.
Replace the fuel pump if that's what the problem is.

Not sure if its the same as a 2001, but I have a 2002 Accent. My son was driving it and it sputtered to a stop. It turns over but doesnt fire. I am thinking its the fuel pump. Do you think its the fuel...


Sounds like a fuel pump,maybe ignition coil,but more likely fuel pump.Check 1 or 2 plugs to see if you have spark since that's easy enough to at least verify.Pull the plug,plug the wire back on to the spark plug,hold the little plate of the spark end up against the engine block,and turn over real quick.If you don't see anything first time,try once or twice more.Try another plug.If they both spark...you have spark lol.That leaves fuel and air.Even with a serious air problem,it should start and is not likely to just quit.Fuel pump probably is difficult.I have a 1995 and it is under the back seat as a cap on top of the tank :( Pulling off the seat was easy.There is a lock ring on the cap/pump that was slightly rusty,enough so that I had to buy a used tank and a new pump.If you want more specific location of your fuel pump,call the dealer or a shop.Someone will usually give you free advice to attract future business.
Good luck! Greg

1994 Chevrolet Astro It takes 2 to 5 cranks to start. Each crank turns the cars electrical stuff on and revs the engine however it doesnt start.What is the issue?


Either you are not getting spark or not getting fuel. A bad crankshaft position sensor would cause no spark at all. You can pull one spark plug, place it back on the plug wire. Lay the plug electrode next to a metal surface. Have someone else crank over the engine while you observe for spark. You should see a spark jump from plug to the metal surface. (plug electrode should be no more than 1/4" away) If you don't have spark, put the plug back in and move on to the next plug and try that one. (the correct way is to use a spark tester) If you have no spark in any plug, you may want to test the crankshaft position sensor with an ohmmeter. You can also use a meter to test power at the ignition module.
If you find that you do have spark in every plug, then it's possible that you don't have fuel. There is a fuel pressure test port on the fuel rail. There is a cap and a valve. With the key in ON position ,you can place rag over the test port, press in on the valve and there should be fuel that comes out meaning there is fuel pressure. (the correct way is to use a fuel pressure gauge if you have one)
If you find there is no fuel pressure, turn the key off and back on again. You should hear the fuel pump. If you can hear the fuel pump, then it is working. That means you may have a plugged fuel filter or faulty fuel pressure regulator. If you do not have hear the fuel pump, check the fuse and fuel pump relay. You can test the relay and a fuse with an ohmmeter on the ohm setting. You can also use a voltmeter and check power to the relay and also to the fuel pump to test for 12 volts. If you have power to the pump but the pump is not running, it is likely faulty. If you don't have power to the pump, then either the relay or fuse is bad. If they test out ok, then test power from ECM.

These are the most common causes of a no start. If you have any bad sensors of any sort, it would likely set of the check engine light. Then the computer should be tested for engine codes which can be done with a scan-tool.

Car turns over but won't crank. spark plugs are


Turning over and cranking are often the same thing, so Im not sure what your asking... Do you mean the car turns over but wont fire, or start? If thats the case and as you say the plugs are getting spark, then your problem is gonna be the fuel pump 99% of the time... Try this little trick, have a friend hit the fuel tank from under the car with a NON metalic hammer (ie a rubber or wooden mallet or chunk of solid wood etc) while your trying to start the engine. If the car fires up, then dont risk doing that trick again as it probably wont work twice, and get it to your mechanic to get a new fuel pump installed. If it doesnt work, (it really is a 50/50 thing) then get it towed and have the fuel pump changed as its still probably the problem...

1988 5.7 TBI Nightmare This is the start of what the problem was and is, I had a RV cam installed when the engine was rebuilt a year ago. the cam was not a computer friendly cam so after a round with the rebuilder and discovering the specs weren't the correct ones for the cam I installed a 3702 edelbrock cam and lifters with a 7800 timing chain and gear set after I had tried two chips from Jet and no improved performance and the 3rd chip was to be for the cam and that is what is in the ECU now and I have tried about 5 different BCC chips and the bottom line is the power is there but something is happening its hit and miss the idle will sometimes lope, is stalled when first started and acts as if its starving for fuel or its bogged with to much fuel. the fuel pressure is 10 - 13 psi and I have R/R the TPS, IAC, ESC and knocks device , EGR and Solenoid, MAP, Temp sensor, and the Dist is a Procomp 10001 with a MSD-5526 coil. the Throttle Body was rebuild and the ECM was replaced with a Rebuilt ECM. it will smell rich etc. but with the things that goes on it does not show any codes?? I have no clue just feel stupid this is been a simple thing that is kicking my **** and now its a challenge but still loosing the fight too far in and too much spent to stop,. LOL Help !!!! The BCC is a california vehicle AFBX, 5.7TBI TH400 A/T P.S. the key can be turned of and back on as the engine not dying and seems to correct the power and run problems but will not last goes back to running bad or with problems. ?
