1990 accord won't start, engine turns over and put in new spark plugs and wires. What else should I check/do?


Check for gas and spark to the engine. I'm thinking a '90 accord might be multi-point injection, although they transitioned about then from throttle body injection to multi-port injection. Either way, you need to check if the injectors are firing and putting gas into the engine. Does the fuel pump work? Is there pressure in the gas feed line?
Usually, a no start is because the engine has lost either fuel or spark. You need to check for both. Use a spark tester from parts store- a cheap and easy test for spark.

2005 Jeep Cherokee miss fire on fifth cylinder


Pull the spark plug to see if it is oil fouled, preventing firing. If it is, you may have a mechanical problem in cylinder 5- do a compression test to check for low compression in that cylinder.

If plug is clean or only showing black sooty deposits from unburned gas, the problem could be either in the secondary ignition (plug, plug wire, coil), or an injection problem. Try a known good spark plug and spark plug wire, also a known good coil, if plug and wire wasn't it. If checking for spark, you need to see a blue snapping spark when cranking engine to verify good ignition. A weak or orange spark, or intermittent spark is an ignition problem.
To check injection circuit on number 5, you can purchase an inexpensive "noid light" at parts stores. It plugs into the injector connector, and if circuit is good the noid light will be blinking when cranking the engine over. It is rare for injectors to fail, but if circuit is good and no gas is getting into the cylinder, injector may be bad or plugged.
Good luck.

Vehicle will not start. It will turn over. Power is good. It did this once before a couple weeks ago. The next morning it cranked right up. What do you think?


It takes three things for a gas combustion engine to start and operate---air, fuel and fire---air is usually okay, fire sounds okay, according to you having "power", and the fact that it is intermittent---but still, check for spark---have someone wearing insulated gloves, unless they don't mind small pulses of 12VDC at about 50mA, which is not that bad, and have them hold a spark plug while still plugged into the wire very close to, but not touching, chassis ground. Or, put the spark plug while in the plug wire in a dark area, like down into the engine somewhere, and look for a spark. Either way, if your buddy feels a pulse or sees a spark, then you have fire. If not, it would likely be either the ignition module, usually in the distributor housing (under the rotor), or the ignition coil---you can obtain a schematic and check voltages if you wish---more often than not, in Chevys, it is the ignition module.

If you have fire, then it would be fuel related...depending on the delivery system (fuel pump, electrical or mechanical, or injection)---for an intermittent problem like this, it is likely electrical for fuel delivery, so not a carburetor or mechanical fuel pump---I would bet you have either tuned-port or throttle body injection---throttle body injection is one big port, like 1/2 carb, 1/2 fuel injector. If you have fuel rail injectors, then either they're all bad, or the ECM that controls them is dead (very unlikely)---my guess, if you have fire, is the fuel pump. However, I did have a Chevy Corsica with a bad injector (throttle body), which had the same symptoms.

I have compression, gas and air to the combustion chamber, just no spark why won't it start?


If you don't have spark then that is your problem. First try changing the spark plugs and wires. If that doesn't fix it then it is the ignition system. Let me know if the first two don't fix it.

It cranks but wont start. Checked for spark with the lead plug wire from the coil to the distributor cap. No spark. I changed the coil still no spark. I've been told its my fuel pump. But I've...


if you are sure there is no spark and you have replaced the coil,then the only other thing it could be is your spark control moduel.it works off your computer to tell your plugs when to fire..somettimes they go out only when they heat up and will start working again after they cool down,,but sometime they don"t give you any warning and just stop working all together.. would say you have a bad Spark Control Moduel.....it is pretty easy to fix, just make sure you use or buy the right tools to take it off , ask at the Auto parts store to get the right tool, and the right part..

2000 Eclipse GT turns over but doesn't start. Fires once in a while but won't run. Had timing belt replaced.


Hi, if the car turn over, and it don't start. Then it is like the engine don't get fuel. Or bad a spark plugs. Most common problem is the fuel pump going bad.

It could also be a bad fuse, but a easy way to check if the fuel pump is ok is to have someone stand at the back of the car when you turn the ignition. The fuel pump should make a buzzing sound for a few seconds. And if you don't start the car right away the fuel pump will stop.

If you don't hear any buzzing from the fuel pump/fuel tank then you have a bad fuel pump............

2004 gmc jimmy, tried to start fired twice didnt catch now just turns over,i can here fuel pump and smell gas.replaced ignition coil??? still wont fire


Check the ECM/BAT fuse. this fuse controls the ECM and the fuel injection circuit. If the fuse is ok, you need to check for voltage at the spark plug. Pull the #1 spark plug. If the cylinder is getting fuel the plug will be wet with gasoline. Put the spark plug wire back on the plug. Now crank the starter and look for a spark from the spark plug electrode. If you can let me know what you find from these tests, I can help you determine the next course of action.

My car is not starting anymore the plugs keep getting soak with gasoline does anybody know why?


The fuel soaked plugs are what's called "flooding". You need to troubleshoot the ignition system, my guess is that you're not getting spark to fire the cylinders. Was this a gradual thing or did it just fail one day?

Turns over but does not fire. Has a engine code of 82 ignition 3x failure


it could be either due to gas or ignition problem. verify if you have ignition output by checking for sparks by removing one spark plug reinstall it at ignition cable and touch metal part of the spark plug to any engine part (metal only) observe for spark while cranking the engine (two man job if you dont have a remote start switch) spark should be whitist or bluish. if no spark spark check ignition electronic module replace as required. if you have spark check for gas supply i am assuming you have throtle bodied injection observe gas being injected at the venturi chamber while engine id being cranked.
