SOURCE: have a 1994 chevy s10

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

SOURCE: my s10 will turn over, but wont squirt gas through injecter

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

SOURCE: wont start has fuel and has spark

RC ralston
Your problem is a leak in the cpi pletium most likely the pressure line has a leak
had same problem with mine $45.00 PRESSURE LINE KIT AND $15.00 GASKET FOR PLETIUM and 2 hours labor problem sovled.
You can remove vortec cover and remove air regulator to look inside pletium. I had gas vapor on driver side . that is where fuel lines are. fuel regulator is on passenger side. turn key on and look in hole and see where fuel is spraying. taking pletium off you can again turn key on and make sure where fuel is coming from.

SOURCE: chevy astro van turns over but wont start when

Check to see if the fuel pump is kicking in,
when you turn the key on without starting the van you should hear it kick on for about 2 seconds,

It could be...
A clogged fuel filter...
Blown fuse for the pump..or bad pump relay..
No gas
Bad fuel pump

SOURCE: 90 chevy k1500 350 tbi fuel problem starts but wont stay running

try bypassing the oil pressure switch on the back of the block behind the distributor, if there oil pressure switch goes bad it will do this. had one that drove me nuts trying to fix it then figured out I had to buy a book and low and behold thee it was 3 wire oil pressure switch you can't see between the engine and fire wall just behind the distributor and costs 8 bucks to buy new.

How do you replace the fuel injectors in a 94 chevy astro


I believe a 94 astro has a cpi system this is a central injector with 6 tubes with poppet valves this located inside of the intake manifold,the top half of the plenum comes off and then the central injectoris inside,make sure your fuel pressure is up to spec also

92 C1500 Chevy wont start. Changed plugs, wires, distributor, rotor and fule filter. Pump runs when key is turned on. Poured gas to the distributor and starts up and runs fine. but jerks ar high rpms...


So you threw parts at it. No harm intended. Should have started with the adding gas part first. You know the filter is new and it does run! Are the fuel pump amps correct,pump mech bound,no fuel volume, pressure regulator work correctly? Does the pump run in start mode or time out? Now the harder stuff. What does the spark and timing look like,What is the computer seeing and then what command is it sending?

Astro van wont start


Did you check for spark? Is it getting gas at the fuel rail? If there is no spark then it could possibly be the crank position sensor, ignition module or coils but the coils do not all go bad at the same time.

underneth the intake manold is were your fuel injector poppet nozzles are, more than likely the fuel line hose that goes thru the back of the intake is split and leaking fuel underneth the intake manifold if you check the fuel pressure you will find that the fuel pressure will drop down to 0 psi as soon as the fuel pump shuts off and it should hold pressure
