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.

Does a 1996 chevy s10 pickup 4.3 vortec have a saftey cut off that will stop the fuel from getting into the spider injectors


Sorry there is no safety valve or switch. Only Ford products use an inertia switch.
Have you checked for power and ground at the injector connector ?

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 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

Isuzu Hombre pickup, 2.2L Vortec, Won't Start.


You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.

I have a 1998 Isuzu Hombre 2.2L two wheel drive pickup (Made by GM is same as Chevy S10). Ok, here is my problem. It just suddenly stopped running with no warning. It will crank but shows no sign of trying...


The oil pressure sender is a good idea.It sounds like you know what your talking about have you tried spraying a little starting fluid in the throttle body to see if it will start?do you have an injection pulse tester you will need one.if you have no injector pulse but of have spark suspect a bad quad driver in the computer.or possible oil sending unit but this usally just shuts down the pump.Good luck let me know.

Is there any way to test the injectors on my 98 chevy S10 4.3


DID you put in new gas, fuel treatment, new sock on fuel pump, all new fuel filters, buy inline fuel pressure gauge, check for codes?, this is not a carb where you pour fuel at it , do you have a repair manual for your truck and have you checked troubleshooting guide?

96 s10 won't start


I would start with checking the battery, belts and fuses. Some places like Autozone will check the battery under a load for free. If all that checks out, then move on to fuel and spark. That will give you a good indicator of where to go from there. If you have no spark then you are moving on to your coil, distributor, etc. If you have no fuel then you would check your filter, injectors pump etc. Keep in mind that a broken timing chain/belt will cause a no start condition as well, as will a faulty neutral safety switch, so if nothing else seems to add up you might check those as well. good luck
