no spark? Ignition?

It sounds like the wiring can be the issue this guide can help confirm the problem so we can fix it.

Please run down this guide and report back.

I had a small fire on my engine drivers side rear of the engine the fire was put out fast battery disconnected fast replace the wires it started up and drove maybe a half a block then died right now the dash and nothing works on the dash the fuel pump does not come on and there was no spark any ideas what went wrong

you probably STILL have damaged wires either inside or in engine compartment. check to see if any fuses blown under hood

No fuse block under hood. Fusable links.

No lights on dash come on either. Going to check ignition. Sensor in exhaust is not connected.it ran for maybe 3 minutes after we did the wires before it just shut off. No fuel no spark

Not ignition. I will replace all fusable links next. Fuse for instruments keeps poping

then check that wire or wires going to the gauges there will be one for each instrumentyou more than likely have wires melted together inside harness under conduit and tape. if you are lucky you didn't burn up the ecm or another module. see if you can scan for codes that may tell you what problem is if you can get a reading.

Will do.dealership mechanic told me as a rule a fire where wires melted to frame they total it.the fact it ran for 3-4 minutes really means nothing.so its back under it for me. Think I'll sell it for what I can get.

One cylinder has no spark at all one has .. . . speratic spark,two are just fine. I've replaced all plugs & wires, both ignition coils and the control modul. The only other wires i see go to sensors how can i test which one is the bad one, or is there really another "brain" somewhere (every one tells me there is no other "brain")?

Welcome, which control module did you replace? Ignition control module? The two cylinders your having trouble with, both plug wires come off the same coil? With your system, one coil fires two plugs at the same time.

Thank you for your quick responce. I replaced the controle module the two ignition coils plug(sit) on, is there anouther one? where is it?

The two plugs wires for the cylinders where you have problems, are they on the same coil?? The computer controls one coil on the white wire. It controls the other coil on the orange wire. Can you check for trouble codes? Right now, I can't tell where your problem is located?

One ignition coil was bad, before replacing with a new coil I switced to see if the other plugs would spark and they did,so instead of cylinders 2&4 not fireing now 1&3 so we replaced both ig coils & controle moduls but the problem still exists. How do I get the code number?

With obd11, you need at least an obd11 code reader. Your firing order is 1342, 1 & 4 on the same coil, 3 and 2 on the same coil. Something isn't right? If 1 and 3 are misfiring because of spark, they are on different coils. Maybe I misunderstood?

96 S-10 Blazer 4.3 TBI just died on me thought it was the fuel pump replaced it still dead. I have no power going to the fuel pump, and there seems to be no spark. Replaced the ignition control module still nothing. And i cant seem to get a code it just says no link. I'm puzzed any idea's out there ,battery seems week could it be a bad module even though its new .Relays seem to be working is there a fuse in the Vehicle Control Module or is it bad. Oh yea it has 96,000 on it

Lets get the fuel to reach the injectors. Below you will find the fuel pump relay. Get help by having someone to cycle the key to On a few times to listen whether the relay is clicking-is it? Fuel pump relay location below at no.3 left top corner square box.

the relays are working still no juice to the pump and there is no fire at the plugs still baffled

At fuel pump relay at dark green and white wire should have battery voltage coming from the computer-check this out.

Electrical problem
1996 Chevy S-10 6 cyl Four Wheel Drive Automatic

My S-10 Blazer will crank over but will not start. I have checked voltage to the coil and the distibuter. I put a new coil and ignition module in and still no change. The out put of the coil is 12 volts with the key on but when crancked it drops to 8 volts instead of pegging out the volt meter. I am stumped

I got it, it was the crackshaft sensor. The new one must have been faulty.

one hour service, not bad!

We have no spark. Up to now we replaced the control mudale with a new one and the computer with a used one. On replacing these parts it started and ran for a minute or so then stopped with no spark again. What do you suggest to look for as the cause? Thank you. Fr Spinler.

Hi Ruben C Spinler, Welcome to 2carpros and TY for the donation

Check and test the coil and distributor pick-up coil-double check computer for loose connections

We have checked all that you suggested and still we have no spark. There is no power to the coil and distributor area.

Do this power the pink wire on the coil from the battery positive post and attempt to start-if it starts either the pink wire is open or the ignition switch is bad

Thank You I did as you suggested and got it to run. Ruben C Spinler

I have a 1994 chevy s10 blazer with the 4.3 v6 it has no spark to the distributor and no gas coming out of the injectors when trying to start

injectors wont' get gas if no sspark scan for codes first then you can go to site here and look for your system under how to repair tuneup and it will walk you through how to check it.

What is the 8th digit of the VIN#?

My '93 S-10 cranks/turns over, but won't start. Sometimes it starts fine but lately I've had this problem. Tried STP fuel line cleaner and a fresh tank of gas, also tried pouring a little fuel down through the top of the air filter, still nothing.

What should I investigate?

Welcome to the forum. Did you visually check for spark at the plugs, engine cranking? If you have spark everywhere, use a gage and check fuel pressure.

A mechanic investigated and found out it was the ignition module and pick up coil.

Engine Mechanical problem
1992 Chevy S-10 6 cyl Four Wheel Drive Automatic

I have replaced the ignition coil spark plugs and wires cap and rotor but im not getting any spark what can i do to fix this problem.

Does the rotor turn when you crank the engine? Is the coil in the cap or separate? Primary voltage to coil, pink wire, goes hot when you turn on the key. White wire should have a tach signal, engine cranking. A couple other possibilities, pick-up coil and ignition module? Can't be sure at this point?

rotor is in cap and yes it moves but dont know about pickup coil havent replaced that dont know where it is but i take the center plug wire off cap while cranking and get no spark would the alternator cause this problem as well

Check primary voltage to the coil. The battery has a full charge and the connections are good? Use a digital multimeter leads across the battery posts, everything turned off. The generic spec or a fully charge battery is around 12.6 volts. If the battery has a full charge, the alternator should be ok. The ignition module and pick-up coil are inside the dist.. Right now, I'm not sure of the problem. I wouldn't replace anything without being trying to be sure of the problem.

Use a testlite on negative side of coil, engine cranking, the lite should pulse.

The fuel pump was out replaced that replaced the fuel pump relay and the fuse.no spark to the sparkplugs. checked the condenser its ok. Could it be a coil in the distributor on a 1992 chevy s 10 4.3 v 6 please I need help!!!

i was having problems about two weeks before it seemed like truck was choking found my emissions hose cracked changed that did not drive for a week started it up drove about 1 mile acted like it was choking after that wouldnt start.relized fuel pump wasntcomming on changed that changed the fuel relay and thefuse still wont start condser is good bought a new coil.the person said the sparkplugs getting no spark help

what engine is it? it makes a difference. also check the ecm b fuse in your fuse block.

Truck drove to work, but will not start, it cranks and there is the smell of gas, yet there is no spark at the plugs, or at the top of the coil, replaced coil, recharged battrie and truned it over and over and it just will not start. It just died.
