    thankyou for your assistance, the fellow that is working on the car for me seems to feel that it is a purely electrical problem, the car was trashed by vandals windows & heaps of stuff but we are having major problems with getting it to start (the ignition barrel , casing etc was completely wrecked but we were able to hot-wire it & got it going, once we installed the new ignition it started, with no problem.



    but when taken for a test drive the car coughed & spluttered when rev's became low but was ok when accelorating. i stopped to run an errand & car re-started no problem... but then went cough -splutter & just died after about 200 metres. couldn't clutch start or even hot-wire. it is my sons car & been neglected service wise etc. The engine system warning light is on & he has now informed me that it has been on for about 3 weeks before the vandalism. can you offer any other possible solutions please. regards kerrie

You must check the wires coming into the ignition module with key in the on position, if 12 - 14 volts are not present the ignition switch should be replaced, if the distributor or ignition module has power you need to check all grounds. Also be sure the ignition coil wire or wires are ok.

The spark plugs needs to be checked.as you have replace the coil pack the spark plugs needs to be checked.
you need, spark, compression and a proper fuel mixture for your car to start. Generally, the compression gives way over time, so it is the last thing you should suspect if this problem appeared overnight. First thing you should try is to turn the key to the "on" position (not the crank start position). You should hear an electronic hum coming from the fuel tank. If you don't hear the hum, check the fuel pump relay or fuse. If those are fine, the fuel pump is suspect. If you do hear the hum, your fuel pump is working fine. Check for fuel pressure in the fuel line. It should look like a valve like the one you might find on a bicycle tire. If fuel sprays out, your fuel pressure is fine, which means you can suspect the spark. The battery is not the culprit (it turned the starter remember). Check for spark as noted above. If you don't get spark, check spark from the coil. Depending on the model and technology of your car, you can then suspect the ignition control module (esp. if it was a hot day) , as well as the distributor and all its components like the rotor and distributor cap.

Mitsubishi endeavor 2004 coil pack burnt out changed and turns over but no start spark plugs wet from fuel but not starting


There are so many possibilities, fuse, command module, crank signal? Is the module getting 12 volts. It is rarely a whole ignition coil pack goes out unless of a short. Was the unit burned up? If not, it could have a bad crank position signal. The cam sensor is mainly for fuel and crank sensor is mainly for spark.

What could be the causes of injectors not opening and spark plugs not firing


A long list of things. From fuses to ignition switch to ecu to security alarm and more.

Here is how to start looking: Turn the key to on. Do the dash gauges and warning lights and check engine light come on? Then power is getting to the switch and being sent out from it. Next, use a test light and check for power TO the coils and TO the injectors with key on. All four injectors use the same color power wire. My wiring diagram is poor quality, but it looks like a green wire or possibly a gray wire-remember same color power wire to all injectors-the other injector wire is a ground wire, and they are all different colors. Pull one injector connector off and check for power on one terminal with key on. And could do the same at the coil pack. With key on, the white wire with red stripe to the coils should have power-actually, the white wire is spliced and two white wires are shown going to coil pack-this is the primary current to the coils- is hot in run or start.

If no power to coil or injectors, here are the fuses to check: in the under hood fuse/relay block: ecu-10 amp fuse, Eng-15 amp fuse, and these maxi fuses: fuel inj-30 amp fuse, Main- 80 amp fuse, Ign-40 amp fuse. And one more- a designated Main fuse-15 amp fuse.
If these fuses are good, should have power going to injectors and the coil pack with key on. If the key is turning on the dash, some of those fuses are known good, but need to check all of those listed.

I will stop here, and wait for your reply. You get this far, you are on the way to diagnosing the problem.

My 2000 honda civic wont turn over and has no spark but the ignition coil and modual are both fine


Won't turn over? Do you mean the starter won't crank the engine over?

Or the engine cranks over and won't start, and you have tested for spark when cranking and have no spark? And then you have tested the coil and ignition module, and they tested out good? Am I on the right page here? If so, maybe the next thing to check would be the crank position sensor. The ecu (computer) signals the ignitor (ignition module) when to initiate spark after it digests the signals from the crank position sensor and the cam position sensor.

Could it be the EGI Main fuse?


In a crank no start condition it is always important to find the cause before throwing parts at a car. The only things required for an engine to run are; fuel, spark and air. At this point it sounds like you have no spark at all. I would begin chasing the circuit back from there.

On to the egi, pull an injector out keep it connected and try to start the car if fuel comes out you’re good. If not you may have a problem with that relay as they have been known to give issues.

But as you state you have no spark when cranking I would start there.

Here is a link to a well written walk through for diag on a crank no start condition

My 98 gmc 1500 V8 5.0l won't start. Has good spark


Spray starting fluid into the air intake of the engine, if it starts and you have fuel pressure you have no injection or injector pulse as we call it. Check ECM fuse one and two for continuity if it starts with fluid..

91 camero rs starts runs 10-15mins and dies . Will not start again til cold a


Hello Ryan, start by checking the battery terminals and cables. The cables on these Camaros are known to corrode and cause intermittent starting problems. The next time it stalls & won't start, check for spark. If no spark, the ignition module, pickup coil, or ignition coil is likely the problem. This model did not have a crank sensor. If spark is present, check for fuel pressure. I hope this information is helpful.

1984 Ford Bronco II new distributor cap, rotor, wires, plugs, control module, coil, starter, alternator, carburator, fuel pump. Put new control module on yesterday had spark for a little while, but now no...


Low battery voltage can keep the coil / ignition control from firing. You need a good 12V to get everything working right. Get a full battery charge and try again. It might also be flodded by now.

Engine died & wont start no spark ignition coil tested good


try your ignition module in the distributor much more likely. just install rebuilt distributor if that is the problem , if you just replace module the main distributor assem will **** out shortly after.
Make sure you check for broken timing belt also it is one of those two!

Engine will not start


could be your distributor contact point. if you do not have contact point, then the electronic part that replaces your contact point. some called it the electronic ignite r.

you should concentrate on the spark. you can check the presence of 12 volts in your coil while starting.

the primary windings of the coil are the one in the clips or screws. check be sure that you have positive 12 v on one wire and pulsating negative from the other terminal. the negative pulses are coming from the contact point.

tnx 4 using fixya,
