Hey all. i just fixed my car. i burned out the Ignition coil module so i replaced that along with replacing my coil and alternator. after we got the firing order situated we fired up the car and she ran. i drove it around a little after with minimal problems. when i floored the throttle it gave me a studdered one time but that was it fine. i turned it off got ready for work and left for work and all was well. i came out 4 or 5 hours later and all of the sudden my car wont start again. after testing a few things i find out that my injectors aren't spitting fuel into the throttle body. can anyone help me? i really need to get my car out of my jobs parking lot because i work at the mall.

 

Almost sounds like your fuel pump crapped out. Can you hear the fuel pump prime when you turn the key on? That would tell if it's dead or not, but priming doesn't mean crap in telling if you have good pressure. That's something you would check at the TBI unit.

 

i found out it wasnt the fuel pump. i had a chevy tech check it out and im throwing code 53 passkey fail? does anyone know how this works or what to do?

 

A passkey fail (your VATS system) would also mean that your engine isn't cranking over AT ALL (starter acts dead), and the security light in the dash is on. Knowing that info would have been helpful, read this: http://www.thirdgen.org/vats_passkey_system

 

could that code be the reason that im not firing?

 

You should have a no crank...and obviously then, a no fire. But is that an old stored code, or a current issue? A passkey failure would disable the engine starter altogether.

 

i dont know for positive if it was throwing the code before it died. what i can say is every time i drove the check light would come on and when i turned it off it would go away when i started it again. considering that im not running any pipes i figured it was the lack of an O2 sensor. but now it will start cranking over but wont wife at all. like i said the injectors arnt firing at all. do you think that the pass key fail is the reason for me not getting any gas to the injectors? we also found out that the chip in my key was dead so i ordered a new one and it should be in tomorrow so ill be sure to post tomorrow as well. but if the key doesnt fix the problem im lost. we also may think that the ground in the injector wire is no good or we may have had something come lose through out the lines because we hooked a test light to the battery and the ground wire of the injectors and when the car was off it lit up as we knew it would. as soon as we turned the car to on but before trying to crank it over it would go out. any ideas? i know its alot and i apologies

 

HUH? Say that again

 

i have owned the car for about 2 months now. it was working fine then i was driving and the car just shut off. after pushing the car home we noticed there were a few things wrong with it. we found out that my alternator had died. we replaced it. car didnt start. we replaced the coil. car wouldnt start. replaced the ignition modual and car started and ran but we herd a loud hissing noise from the injectors. so what we did was jiggled the electrical connectors on top of the injectors and the sound went away. i test drove it and had one time where the car studdered to get on it when i stomped the gas. i though nothing of it because it was a one time thing. i drove the car home, turned it off and got ready for work and an hour later drove the car to work. everything was fine. came out of work that night after a 5 hour shift and tried starting the car and it wouldnt start. tried jumping it and still nothing. we got it home and i had a chevy tech check it out and he said that i had a pass key fail code 53 that my car was throwing. from what i have been hearing the pass key fail will disable the engine from even cranking. my car will crank but wont run. and the injectors are not firing at all so no fuel is getting to the engine. my question is is it at all possible that the pass key fail would just disable the fuel system? im getting a new key today and im going to keep everyone posted as to how well it goes. but if anyone has any other input or can help in any way i would greatly appreciate it. thanks

 

If the Pass Key is bad then the car will not even turn over. Read the link on Camaro 69's fourth post. It says that sometimes car will turn over but injectors will not have power.
