97 fire, 2.2
alright, i was driving down the road and the car just died...the car has gas, i added more to be sure...checked fuses, all are fine, so i pulled out two plugs and they are dry, along with the cylinders...so i removed the fuel pressure regulator and turned key to 'on' till the fuel pump ran, and gas comes out, so i know the injectors are getting gas. when i try to start it, it just turns over and over like i'm out of gas.
so, what are the things that would tell the injectors not to work? is there something else that could've broken to make this happen? my low oil pressure light comes on once in a while while idling, could that be something?
i need some ideas, it's so damn cold out i can only be out there for about 15 minutes at a time. thanks guys.

i'm thinking maybe the crankshaft position sensor....does it sound like maybe that's what it is? what happens when them go? man this is annoying...i've been checking different things for a while now and my batt is dying...go figure.

So I take this to mean that you have no idea if the problem is lack of fuel or lack of spark.
Just because it does not start does not mean the injectors are not working.
A simple test for no fuel is to try a quick shot of starting fluid or carb cleaner into the TB then see if it tries to fire.
Check for spark by pulling a plug wire and seeing if its sparking while cranking.

my guess is you read it like 'blah blah blah meh blah like i'm out of gas bleh blah blah'.....you missed the part where i said

which in turn suggests that the injectors are not putting gas into the cylinders.

read the subject line...it states 'injector problem, cylinders not getting fuel' so i must know that it is obviously a lack of fuel...
please read it all...it would help us both out. thanks for help, even tho you were a little off

how did you determine that the cylinders are dry?
idk why you are getting all upset at protomec when i see no where in your post that you actually checked the spark. like he said ....try the starting fluid
i'm not mad at protomec
i even thanked him for helping...
i pulled the plugs out, looked inside...if there was no spark i'd have alot of gas on my plugs and in the cylinders..but..no gas..left a plug out and tried starting, still no gas... its a positive that the fuel isn't getting injected...so....at the time i didn't check the spark since i had already figured out there was no fuel getting to the cylinders..i went out there to do the starting fluid and my batt was dead, so soon as i can find someone to give me a jump i'm gonna try that.
is there anyone that can help me out with the original question? what might make the injectors not work? thanks.

plugs being dry is not a test of not getting fuel.
But what is lacking here is a reliable sense of diagnostic direction.
Even if you are correct and you are not getting fuel, spark is more important.
The ICM is 1st in the chain. It sends the signal to the PCM to give fuel. No spark (1st) = No fuel (2nd)
If you don't have spark, the crank sensor or module could have failed.
If you do have spark, then you can head to checking out why there is no fuel.

yes, i do have spark....put the starter fluid in there and it ran for about half a second after a few attempts...i could have done it sooner but the battery was dead...i finally got a charger on it. any ideas about the no fuel? thanks a bunch.

cars running...i took off the batt to let the computer reset and tried again, and nothing...started pulling out the wires for the injectors and all kinds of stuff...then pulled out the plugs again and they were wet...so i put everything back together, reset the cpu again and it started right up. thanks for all the help guys. and protomec...thanks for the heads up on the 'No spark (1st) = No fuel (2nd)' because i didn't know that. i apoligize for my ignorance. anyways, thanks again. hopefully something on the car didn't just decide to work for an hour or two and quit again.

update:
same thing again...it died driving down the road after i just let off the accelerator, which is when the oil light always comes on, and i was coming down a hill...could i just have to little oil pressure? i'm thinking it's either of three things, someone help me out here.
1. ICM
2. CKP sensor
3. low oil pressure
i'm already running 10w30, and it still never cleared up the problem, if it's even a problem to begin with...obviously i want to try and fix the icm and ckp sensor before the main bearings and/or oil pump...anybody got any ideas as to what the icm does when it fails, and what the ckp sensor will do when it fails, and if it might be my problem? or if such low oil pressure will do this?(like in an accident, when you suddenly lose oil pressure, doesn't it kill the fuel and spark?) i don't know what to do here...i know when the car started running again i never really fixed anything, just messed around with some wires and all the fuses which are still good...so something must be failing and working whenever it wants. help me out please!!

the oil has nothing to do wiht it. i ripped a hole in my oil pan, dumping all the oil out at once and still ran until i shut it off.
if you want to check a sensor, you need to find out what kind of range it operates in (either voltage or resistance) and check the output with a multi meter.
if you find nothing wrong wiht the sensor , get a junkyard ICM, they cant be that much.
i'm glad it's not the oil...that means it's either the ckps or icm (hopefully)...i'm waiting on a code scanner and going from there...my car is like 20 miles away in a church parking lot (haha..probably the best place for it, you'd think) and i have a horrible multimeter so i haven't even bothered to check the sensor. i've been inquiring an ebay seller on the ckps and icm (used) and i'll probably just end up getting both so i have them. anyone have any tips on changing the icm or ckps? cuz i know it's gonna be a PITA being where it's at on the motor.

i ahve no idea about the 2.2. it sounds like gm really didnt put much thought on the placement of things in the engine bay. ie....the oil filter
the 2.4 has the icm right on top so all you have to do is unplug it
update....
car is in the garage....the ecu looks FITA....the previous owner of the car must've hit a deer or something, and all the wires and @!#$ were just zip tied back in place...needless to say, reading my chiltons and never dealing with an ecu, i ACTUALLY decided to follow the instructions....leading me to believe i just 'unplug' like it says the connectors from the ecu. it fails to mention the TWO @!#$ BOLTS on it, and since the zip tied wires were so conveniently covering the bolts, i just pried...and pried...and did it some more, so now those metal housings on the connectors are in pieces...i might be able to salvage it and use it...but the connectors themselves are absolutely loaded with a white powdery substance. i was thinking salt but i gave it a taste and it tastes like nothing..any ideas??. i'm going to take it apart and clean it up, do some continuity checks and put it back on the car and maybe it'll start.
does this look infected??
also note the plastic pin holder things that ripped off of the plugs...

i would get a new one form a junk yard
yeah, no good junk yards around here that i know of..i cleaned it up really good..the closest black connector in the pic had some bad pins in it, so i checked them out and the only bad ones that are used are for the cruise control, but i think it still works anyways. i put it all back in, pulled out my ckp sensor and it was loaded with oil, or tranny fluid...for some reason gm decided to clip the harness to the fill tube, and so any missed fluid must've went all inside the little harness leading to it so i cleaned it all up. now the car runs even better than before...hopefully that was the problem(s) and it won't die again. and no more check engine light
...now to get rid of the brake and abs and air bag light....i get my code reader soon so maybe i'll be able to figure out what the problem was. thanks for the help guys.
