no spark

[itsmelord]

I have a 94 geo metro witch stalled one day after a little while it work fine. it did this before and it turned out to be the fuel relay, so the first thing we did was to get a new one. it did not fix the problem. in fact it does not even start now. we check the spark and no spark could be found so we shoved the coil (this one is a square coil) into are 93 geo work fine. so we tried the spark control module worked fine. before I mess up the adjustment on the electronic ign. in the distributor, witch I don't know how i can test. could some one give me some advise on what to do next. with the key turn on I have 12 volts at the coil.

before it died altogether you was able to start the car then turn it off and it would just turn over without starting.opcorn: eating up gas.

make sure the distributor is turning first. might be a bad timing belt

[itsmelord]

good Idea but It is rotating. more suggestion please

Only 4,000 possible reasons it won't work. MAP Sensor. Fuel Pump. Burned Valves
The heater Core going Nuclear. The Rear Seat Degreaser is plugged with coins.
The Battery Plates have rotated to Horizontal. The steering wheel compiler has
become unmagnetized. Random Cosmic Rays have debugged the ECM.
The gas tank has inverted. The radio has a feedback loop into the ECM.
The headlights have shorted out the crystal coil. An insect has shorted out the capacitance inverter.
The transmission torque inverter has become polarized. Several magnets in the
engine's main spring have become degaused resulting in delocation sparks jumping to the
Gadolinean Power Coil located under the Driver's Seat.....

Heavy contemplation while drinking four beers is called for.

Beam me up Scottie!

How about having a competent mechanic have a look at it....?

Might cost you a few bucks, but the mechanic could probably pinpoint the
reason in short order.

If, however, he says any of the above things, seek help elsewhere.....he is used
to conning women customers.

"If all else fails seek competent help!" Works for me!

DoctorBill..........Sorry! I'm in a strange mood today!

I was having some issues with my car about a month ago. It was running very poorly. When I looked under the hood, in daylight, I could visibly see spark arcing back from the coil wire (the one that goes to the dizzy) to the coil itself. Wires were only 13 months old. I found the receipt, Partsource (Canada, eh) gave me a credit towards a better set. Fixed my problem nicely. Much better acceleration afterward.

What's the lesson I'm trying to pass on? Don't buy cheap parts. I figured new, even if cheap plug wires would be an improvement.

You should consider (if not already done) new wires, new distributor, new rotor, new plugs. Small amount of money to spend on parts that have proven to help a lot of other people on this forum.

I worked at a tune-up shop in CA for a couple years and your head would explode if you knew how often that was the cause of problems with a car: either because of bad sparkplug wires/separated wire components/loose wire components or a bad (probably cracked) distributor. And I saw it on newer cars, too, or with newer parts.

It got to where I could diagnose the problem from 15 feet away before I had opened the hood because I could hear the arcing. We kept a box of old wires so we could slap them on and get it running right on the cheap if the customer was really poor.

Whats funny is some people with V6's or V8's wouldn't notice they were at least some of the time losing a cylinder, and also funny is sometimes I saw engines where the spark would arc out of the wire, go into the block and fire the plug anyway- so it wasn't even missing.

I picked up a distributor from the junk yard that look better then the one I had it even almost look new. I was told that they burned up the engine so the distributor should be OK. There is a little module that mounts on the square ign coil might be a noise suppressor but I don't know. does any one know what it is, and what it does?

[dookeye]

yeah thats the auxiliary dualquadrobioreceptificatifazerifier

[carpenter_jai]

it's the ignition module. it does what dookeye said.

[91Caprice9c1]

Ever get to the bottom of this?

[lawbob81]

Try turning the engine over with the distributor cap off, check to see if the rotor is turning. If it isn't, then you need to replace the timing belt.

I had this same problem, and it took me 2 days to figure out that it was the timing belt that cause NO fuel and NO spark, because the distributor was NOT turning.

I could not find the dualquadrobioreceptificatifazerifier how ever I did find what ,

jai called the ignition module if it the same thing, in this car it is called the FI relay which probably stand for fuel and ignition. both relay sit right next to each other. which did fix the problem now if i ever have this problem again i know where to look first. i called the dealer and they wanted $98 for a coil of wire raped around a post. that is all this relay is with a fancy name, the junk yard gave me one for $3.50. once you find out what it does you could even make your own cheaper.
