The s10 have a fuel shut off relay to shut off fuel supply in case of an accident. They also have a anti-theft system that prevents fuel in case of theft.Pull the fuel line off and crank the engine to see if you get fuel. Sorry I can't be of more help but without hands on vehicle it is hard to tell.Also your fuel pump maybe sounding like it is pumping. In other words it may be running but not pumping fuel it mat have a ruptured diaphragm in the pump.The pump is running but not pumping fuel. Pull the fuel line off at the fuel filter and turn on ignmition or crank the engine you should have about 50PSI coming out.If you don't install new fuel pump.These vehicles are common for this problem the fuel pump runs but does not pump fuel or not enough pressure these vehicle require 57 PSI to start if it has less than 51PSI it will not start unless you use starting fluid then it will run.It will run with less fuel pressure it will just not start with less than 57PSI.

Hope this helps

Check spark plugs, leads, distributor cap & rotor arm, fuel pump, fuel filter, coil pack(s), relays, replace any items that are suspect IE Fuel filter which has probably not been changed since new even though they should be changed on all vehicles every 18 months, all of this can be done at home & will save you a lot of bucks in mechanic/garage fees,

1990 Chevy s10 won't start, have replaced plugs, wires, timing chain, fuel pump,distributor, starting fluid nothing helps


Have you checked for a broken timing chain, that would be the next step. Make sure number one cylinder is up on compression stroke when the timing mark is on 0 degrees BTDC on the crank pulley. Pull the plug and feel the pressure as it nears TDC.

I have a 1998 Chevy Blazer 4.3 Vortech that will not start.


You may want to check your fuel regulator and check your injectors. Had the same issue with a 96 and replaced the whole CSFI spider assembly with a MFI spider assembly and problem was solved.

Does it crank the engine ? If not take a look at the starter connections and the starter.Replace the starter if nessesary.
Ok, now that you got the most common problems out of the way, you should check for spark at the spark plugs. Remove a spark plug and attached to the wire. Get a good pair of rubber gloves and put the thread of the plug to ground and crank the engine. The spark plug should spark a bluish spark. If it has an orange spark the spark plug or wire may be bad. if it does spark fairly good.

Check the fuel pump. if it has an electric fuel pump you should hear it when you turn the switch to on. It is a whirring sound. if you can't hear it. the Pump is bad or the shutoff valve turned off the fuel system. Check it to see if the button is up. If it is then the valve clicked off. Press it down. If it is down and there is no fuel the fuel pump is bad.

If it is a mechanical pump, take off the hose to the carb if it does have one. crank the engine . It should pump gas right away.

If it does have spark or fuel to the sytem, then it is a sensor or other problem.You will have to get a trouble code for it. to narrow everything down.

Check the timing belt or chain to see if it is still good and tight. If it is not your timing belt or chain skipped or cut off. you will have to replace it.

I hope you can get some help from this info . good luck
