I'm having trouble starting my chevrolet blazer S10 1993 model. The fuel pump is starting but fuel doesn't get to the engine. I hope you have some ideas?

'Cranking' is purely the engine turning over. It cranks, almost starts and then it does nothing next time you turn the key? Flat battery.
Or, you turn the key, it cranks, fires and almost starts and then dies? More reasons for that scenario. Check for diagnostic trouble codes. Did you disconnect the battery when you replaced the fuel pump? Did it work after that? Does it have an engine immobilizer and did you reset it after the disconnect?
Make sure you have power to the fuel pump. On this model you should hear a quiet high pitched mosquito in your ear sound when you have all the lights on the dash panel just before you turnover the engine. If push comes to shove, take the fuel pump out, keep the power on it and run it through a bucket to see if you can at least pump water through it. Make sure you let it dry out all the way though before placing back in the tank.
what did you do (replace it) if you still have a miss you may need to tune it up / make sure the fuel pump you bought is for the right psi for your blazer
You should never try a pump without it being in fuel. It uses fuel for lubrication when it is running. If the vehicle doesn't start at all when you first crank it over it is not the oil pressure sender. If you just put the pump in you might want to turn the key off and on several times to cycle the pump then try to start it. If it doesn't start then check fuel filter or check fuel pressure at fuel rail in engine compartment. Is fuel pump cycling at all when the key is turned on? There is a problem with ignition switches on some of these blazers.
2 things that you have to check on no starts every time. Spark at spark plug and fuel. Turn key to run position and listen at gas tank for fuel pump to run you should hear a whining noise. This will only happen for 3 to 4 seconds then it will shut off until engine starts. You can turn key off then to run every 3 to 4 to listen for fuel pump. You may hear the relay click off in engine area even if pump does not run. Fuel pump failure is pretty common. If pump is running pull spark plug out or put a spare plug into spark plug wire and have someone crank engine set plug on engine and watch for spark. This will give you a starting point. Hope it helps.
the relay is either located in the large fuze box under the hood, when u locate this fuze box open it and under the cover it will have a picture of where the relay is in the box, or its located on the fire wall under the hood on a rack with a couple of other relays. hope this is helpful please rate me
