1999 Chevrolet s10 pickup sparking at ignition coil

Showing 6 out of 6 Posts
Question From Nastwold3 on 1999 Chevrolet s10 pickup sparking at ignition coil

1999
Chevrolet
s10 pickup 4x4 4.3 liter V6 Vortek,
179,000 miles

It will start just fine but when I give it any gas it sparks at the ignition coil and stalls out. It started as I was driving home in the rain. It started to stall every time I gave it gas, and when I got it home it quit. the next morning it would start but I get intermittent sparks and it stalls every time it sparks, also if I give it gas it sparks violently and stalls out.

I replaced the rotor and distributor cap, no change.

Any suggestions would be greatly appreciated.

Response From Hammer Time

I don't know why you would change the distributor cap when you saw sparks at the coil. The coil is cracked, replace it. Make sure you wires are in good shape at the same time.

Response From Nastwold3

The coil is brand new and so are the wires, no crak in the coil at all.

Response From Hammer Time Top Rated Answer

If you are seeing arcing at the coil tower, the coil is cracked or the coil wire is open.

Now, if what you are saying is that your testing for spark at the coil and getting it but not at the plugs, then you have a cap or rotor problem.

Response From Nastwold3

Is it possible it is a timing issue with the crank sensor?

Response From Hammer Time

No

Chevy S-10 Engine Looping

Showing 2 out of 2 Posts
Question From evonhofen on Chevy S-10 Engine Looping

I have a Chevrolet s10 pickup truck with a 4.3 liter engine that has been in storage for 10 years. We got it out of storage and fixed it up a little and got it ready for the road. It ran great for the first month. Now it idles and the engine loops in till it shuts off. We replaced the fuel filter and the throttle positioning sensor with no luck. I get good spark and the distributor cap seems to be good. We're running out of ideas and we need some help. I am I college student and my budget is low so I can't afford to keep replacing unnecessary parts. Thanks for the time and any help you can give on this matter.

Response From Mr.scotty Top Rated Answer

Did you drain the fuel out of it and put fresh fuel in before starting it?
If not i bet thats your problem.

Question From AlexFolino on 1991 Chevy s-10 4.3L z pickup, not starting

4.3L z engine. 1991 Chevrolet S-10 p/u
new distributor with pickup coil and module,new ignition coil, new wires, plugs, cap, rotor, MAP sensor. Engine is properly timed. For some reason this engine will still not run. I can get it to partially start and run for roughly a fraction of a second and thats it. 4 mechanics i had even come to my house are stumped. Its getting gas. Each cylinder is getting spark. The coil is good. Compression in every cylinder. However i noticed it seems like theres some gas in the oil when i pulled the dip stick? I disconnected the exhaust even thinking maybe some animal got inside. The engine once in a blue moon (and i do mean a blue moon) will start however but has a very rough idle.
Can anybody diagnose or lead me in the right direction? thanks

Does it run great if you spray starting fluid in the Throttle body?

I had the same problem, with no codes. It ran great if I supplied gas or stater fluid I pulled the fuel line off and it worked fine, but I did not check fuel pressure.
When I unplugged the temp sensor on the front of the engine, it ran at a crazy high idle.
Well, it turns out it was a 2 inch hose, inside the fuel tank was split. It went from the fuel pump to the housing. When the pump began to build up pressure, the line opened up and shot fuel BACK into the tank.
That caused the throttle body to starve for fuel, thus running like crap, then running great, then running like crap again.
It was a 1 dollar fix, but i had to drop the tank to access the pump.

You may have a faulty ECT sensor or wiring to it. If you can get a scan tool you can look at the data stream to see what the coolant temp is. If it is showing
-40* then the computer is dumping the fuel into the cylinders causing it to flood.
The first thing you should do is hook up a fuel pressure guage, double check spark at the plugs, and install a noid light into the fuel injector harness. Crank the engine and see if all of these systems are working properly first. Post back with the results so we can go further. I also need the fuel pressure in psi to rule out the fuel pump.

Just an out there thought as to a maybe with this: Spark plugs hate being flooded and do NOT air dry very well. They can look dry and still the spark will follow the porcelain and not fire out of your sight.

Best fix for that is replacing the plugs and leaving them all out for a while - mark where they went (wires) to save hair loss later.

If that works or anything you find works I suggest taking it for a good ride and let it all clear out of the exhaust and converters if they are fairly ok they should handle this but it is hard on them, T

Well the motor is getting gas for sure. Its spraying the typical cone style spray. Now my question is, will a regular OBD2 scanner (the orange one at advance autoparts) be able to pick this up?

Response From Tom Greenleaf

Scanner will not pick up on wet (even though appearing dry) spark plugs. Car will through a code by simply not running well, T

Question From warden733 on Don't know what to do now

i have a 92 Chevrolet s10 it is running ruff . and if you hold the gas to the floor it will not go .if you push on the gas it act like it wants to die if you back off it will take off . I have done. fuel pump ,flue pump relay, filters , all the fuse , all the sinners , rebuilt the TBI, new erg, EVRV,distributor cap and rotter , all the plus and wires ,oil and filters ,map sinner ,neutral safety switch . exhaust all new . now i now have no idea still running ruff , filing out plus and if you give gas it will not stay running . i drove it all day yesterday. got up started the truck let it heat up took my kids to school as they where get out of the truck it died. it took me 30 to 45 min for it to start aging . Help

You can also check the compression across the board. Your timing chain could have jumped time. Also, I have seen faulty ignition modules and ignition pick-ups wreak havoc and give major driveability problems.
A quick way to find out on the chain is this, remove #1 cylinder spark plug. Disable the ignition coil. Insert your finger into the spark plug hole and have an assistant BUMP the engine over. When the compression blows your finger out of the hole, rotate the crank pulley to 0* tdc. Remove the distributor cap, if the rotor is pointing at #1 cylinder on the cap the chain didn't jump. If the rotor is pointing to any other cylinder, the chain jumped time.

Warden; Rather cryptic information, but could be that it is running too rich? Check CTS (coolant temp sensor). These vehicles are known for faulty thermostats (engine not getting hot enough). Check the coolant level, check the oil for
fuel smell and viscosity. If it smells like gas, and looks and feels thin, be sure to change it. Look at the spark plugs. Are they black and sooty? Or wet with fuel?
