Hello Rick;
You need to drive the truck. Get it good and warmed up, drive it like ya stole it, and feed some premium to her to break up the varnish in the injectors. Replace the fuel filter again in about 1000 miles and you should be ok.
Hope this helps;
Thanks;

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.

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.

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.

My chevy s10 blazer will start for a couple of minutes then shut off. It has a new fuel pump, cap & rotor, spark plugs and wires. The computer is putting out a 1-2 code.


the code 1-2 is just telling you that you're in diagnostic mode (means nothing) fuel pump could be going out or fuel filter

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.

Sounds like a vacuam leak, best thing to use is cold start spray, by spraying the vacuam lines with this you will notice a change in the idle wherever the leak is at.
