Any chance you get take that in to get the codes read. That is important and step one of the process. This will tell you the problem. If you are getting spark at the plug then more then likely you are having fuel problems.

94 chevy s10 4.3 litre engine wont start. Its getting fuel and spark. pretty much everything is new. sometimes after a while i can get it to run. when it does i can drive it anywhere and its starts ri


might pull that cap again and see if the dist. shaft is loose
(side to side play) Sometimes the bushing wears out and the
magnet will hit the pickup,makes the spark irratic.Should have a new rotor with the cap,they also go bad.

My 94 s10 blazer cranks but will not start. It has new spark plugs, battery, and rotor cap. Help? I'm stuck at work right now.


Give it a shot of starter fluid: See if it starts up on that, if not, go out, take off the battery wires, sand the terminals to shiny. Pull a spark plug and check for spark (But don't hold it WHILE checking, that hurts.) I'm guessing the fuel pump has cut out, or the ground wasn't quite there.

I changed the spark plugs and wires on my chevy s10 2wd pick up, which is a 4 cylinder and now it will not turn over. I might have the wires mixed up on the distributer cap. Can someone show me a picture...

Hi. i have a 1994 s10 blazer and it will not start for anything. i changed the injectors and the fuel pump, spark plugs are fine and tubes are in the right posisioon, do you know what it could be.


Anytime a car wont start its missing one of the key things it needs to start. Air, Fuel, spark or compression. The first thing to check is to pull a wire off the spark plug and put a screw drive in the end of the wire. Lay the screw driver on the engine near metal. Crank it and look for a large blue spark it should make a nice popping noise.
If no spark try the same thing with the coil wire. If spark its the cap or rotor. No spark its the coil or module.
If the plugs have spark, try pouring a small amount of gas in the throttle body and see if that starts it. If it does, fuel problem check filter and pump.
If it wont start with either or gas in the throttle body and the plugs have spark then it is either a timing or compression issue. Remove the plug wire from the center of the distrib cap and then remove the cap making sure no wires come off. Have someone crank the engine and see if the rotor spins. If it does not you need to replace the timing chain/belt. If it does spin rent a compression checker and check each cylinder.

Hope this helps.

Replace the spark plugs and wires along with a distributor cap and rotor. Be careful to leave the old wires and plug wires connected to dist.cap, just remove dist. cap from the distributor and lay aside with plug wires on it then install rotor then new cap and proceed to replace each wire for cap and spark plug one at a time so you don't mix up the spark plug wire firing order. Cap laying to the side is used for reference purpose.

My 94 s10 hesitates when i take off i think its a fuel problem


well a new fuel filter should be pretty cheap and easy to install. Could always blow an air hose through it the opposite way if you really can't afford a new one (temp fix or test). Make sure to check the cap and rotor and be sure that they are not all corroded. Also check to make sure that the cap and rotor are both using the same kind of metal. Pull off a spark plug wire at the cap and if it's brass then the rotor should also be brass. It will have a much better connection. Check the ground wires coming off the battery. Check the spark plug wires and plugs for shorts. You might not be running on all cylinders. I know that this is a little broad but it should give you something to go on. Let me know how it goes.

There may be no injector pulse if the computor does not see a RPM signal.
There will be no spark if the ignition module does not see a dist pulse from the dist pickup.......a RPM signal.
Because you do not have both ......I would suggest to check/change the dist pick up.
Follow the wires from the ignition module inside the dist to the pickup which is also inside the dist.
If it is just a bad dist pickup....keep all your old parts as good spares.
Also...is the dist turning? to provide a RPM signal?
You will have to remove the dist to change the pick-up.....mark your timing locations......"rotor position" and "dist body location"before removal.
A quick test before installing the "repaired dist" .....plug it in the the truck wiring and turn on the key....DO NOT CRANK THE ENGINE OR YOU WILL LOSE YOUR DIST ROTOR CORRECT POSITION......as you spin the dist by hand .....the injectors should spray.
