March 12, 200422 yr Okay, here's the issue. I have an early 90's Chevy Cavilier Z24 6 cylinder that won't fire. It worked fine till a couple days back. Now, it'll turn over but not fire up. I turn the key, I can hear the gas pump kick in, so I know it's not that. Air filter is new and the airways are not clogged. I tried seeing if I can get spark from a plug, and found that that seems to be the problem.... I'm not getting any fire.After some thinking, father inlaw and I figured it was probably the Ignition Coils which are buried behind alot of crap and costs 70 bucks. Replacing that didn't work. We checked the fuses to see if the computer is not getting power as well, they're all fine.The thing was showing signs of electrical problems for some time in the form of smoke when the heater fan is turned on high.At any rate, I'm not sure what it could be other than a bad wire or the cars computer gone to hell. Any ideas?Damn, wish I could afford to just take it to a shop. grah!
March 12, 200422 yr ouch...dont know much about working on cars. I learned that when my wife pumped Deseil into here Kia it didnt like it very much. That cost $200 to fix not to mention the tow bill!!!!Hope you can get it fixed roach....sorry I couldnt help.
March 12, 200422 yr If it's a gaz car, you have perhaps the carbon finger who is broken or his pull spring (spiral) is broken too and it don't touch the rotor from the delco after the ignition coil...Look also the condensator, it could be short-circuit !Or the ignition screw in the delco are holed : to see if the carbon finger works good, close the ignition scew by moving the car with the 2nd speed on, and when they are closed, turn on the key without turn on the engine, open it with a plastic turnscrew to see if you have a light flash high voltage, if not, the ignition screw are in short-circuit too at the fixed bakelite who have a fissure or the carbon finger must to be replaced or the condensator...Else, you are out of gaz...Egidio.
March 12, 200422 yr Air Fuel SparkThat is what is needed.I bet it is the CPU or electronic ignition.Test the coil wire against a ground on the engine CAREFULLY.If spark ok then....check the plugs if none then check the rotor. They can break.If none then it is the Electronic ignition/CPU of the car.If the coil / cap&rotor has no spark and they are good then it must be the ignition.
March 12, 200422 yr Author Has 3/4 a tank of gas you freak. LOL :)It's an electronic ignition and timing, no rotors as everything is electronic.
March 12, 200422 yr Author Isn't that the "ignition coils"? The thing we replaced was a long black box that had plugs for all six cylinders. That what you are refering too?
March 12, 200422 yr No I am referring to the actual car computer since you replaced that coil/ignition module part.Fords have a history of them (CPU) going bad so I would bet it could be that.Make sure you diagnose as I put above.You need to be sure that the wires are not bad. The main box is grounded cleanly and there is spark to all cylinders.If not then the box is not being told to fire.
March 12, 200422 yr does it have a dizzy cap (distributor cap) if it does check the lead going from the power to the actual cap, if thats old or has gone high resistance it wont spark.
March 12, 200422 yr Dude.. does the car have tires.. because if it doesn't have tires.. why are you starting it up.. I mean.. Geeze.. think before you ask these things...
March 12, 200521 yr How many miles are on it? The reason I ask, is it possible the timing chain/belt has broken? Does it turn over faster than normal? That is a sign the chain/belt is broken. If it is broken then it would explain why your not getting any spark.
March 12, 200521 yr Author Man, I can't believe you revived this old post. I sold the Cavalier for junk a long time ago and replaced it with a Corsica In the end, I ended up replacing the Module Pack, Ignition Sensor, and one other thing. No, there was no timing belt involved as the thing wouldn't crank at all. I broke a timing belt on a Chevette once, I know what to look for in that kind of thing. In the end, I figured since the thing had 300K miles on it, I didn't want to put anymore money into it.
March 12, 200521 yr lol, didn't know it was soo old, didn't look at the date. Don't check out the forums too much. Now I know to look at the date.
