Check your battery voltage first sir! it should not be at most 12 volts. if it's almost 10volts or lower, then it needs recharging or replacement, (which ever you prefer! you may having spark at 10volts but its not enough to ignite the air-fuel mixture inside the engine.
check also the air filter, there should be not water trace in it! check oil, should not be milky.

First check for battery voltage. Then make sure you have a check engine light when the key is in the run position. Make sure the fuel pump relay is good. Check to see if there is power on one side of the injectors, if these wires have a short to voltage or ground the injectors will not funtion properly. In this system the injectors are supplied with constant power and ground controls pulse width. In these blazers and s-trucks PCM ground sees to become an issue. In mine I directly routed the system grounds to a metal body panel under the right side of the dash. In my Blazer I swapped out the motors and converted from and automatic to a manual transmission. And another problem I found was when I lifted the dash to install my clutch pedal, I broke my brake light switch. In an automatic the brake pedal switch interups the ses light circuit. If the PCM dosent sense the ses light on the system cannot ground. Good Luck with it, At the time I had completed my second of four automotive level so it took me a bit to figure it out on my own. Once I took my level 3 (electricl) it sunk in alot quicker. Happy hunting, don't get too pissed off.

check the fuel pressure to determine that the fuel pump is still good. there should be a schrader valve with a plastic cap on it on the fuel supply line that goes to the throttle body or if you have one fuel injector per cylinder, you will have a fuel rail that feeds each injector that will have the schrader valve that you screw the fuel pressure tester on. most fuel injection systems run 30 to 40 psi, but check a service manual or call a dealer to get the correct psi for your vehicle. if the fuel pressure is within specs, it sounds like the MAF (mass air flow) sensor is the culprit.

Hi,

I would check n replace the fuel filter if needed. Also, it could be one of the spark plugs. Was it running before? Can you think of anything that happened or changed recently?

Make sure battery has a full charge. If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
If you have tbi fuel injection, fuel pressure is 9--13 psi.
If you have cmfi fuel injection, my info says 55--61 psi.

I can't imagine what could cause the engine not to start by just pulling the transmission out.
Are you getting spark to the plugs and fuel to the injectors ?

Are you not getting fuel to the throttle body? Or are you not getting any injector pulse? BIG DIFFERENCE!

If you have lost injector pulse and spark at the same time, the most likely cause would be a failed distributor module.

My chevy s10 2001 turns over but does not start its not getting gas to injectors


Well you need fuel to the injectors, a spark, compression, air and a signal to the injectors to fire for the engine to start.
So if you've got fuel, make sure you have spark to the plugs, the air filter is not clogged, compression is above 120, and the crank and cam positions sensors are good.

Have a 1994 chevy s10 blazer with a vortec 4.3 changed fuel filter,fuel pump,plugs,wires,and module in the disturbuter.still will not start


You need to check and make sure you have fuel pressure, then check for spark at ignition, if those check out then check for pulse width at the injectors. That basically is the electrical signal which tells injectors to spray fuel. Use what is called a Noid light on injector pulse width check. that will eliminate all possibilities other than internal issues with engine. I.E. broken cam, broken timing components, obviously if all I mentioned checks out then run compression test. Good Luck
