i have a 1989 rs tbi camaro
rebuilt 305 engine 3000 miles
rebuilt t5 transmission 0 miles
new battery
new fuel pump and fuel filter

car had a problem where the ignition switch would occasionaly not work and push starting the car temporarily fixed the problem. I eventually put two wires on the starter and made it to where i could push a button with the key on and the car will start. then one night i went about 60 miles from home and the car was running great i parked it and then went to start it again and all it does is crank over using the start button. i thought it was the fuel pump not supplying the injectors with enough fuel pressure put a new pump in it. problem not solved. if i dump gas into the throttle body the car will start but run rough and wont idle. could this be vats?
how do i fix it

 

 

ya the fuel pump works everytime and i got the car started today by dumping gas into the throtle body that eliminates vats starting to think its a bad sensor or vacuum leak

 

this might be a dumb thing to say but is there VATS anywhere near this car? A bad VATS module will cut the fuel to the engine.

 

so you are getting fuel pressure are the injectors opening

get a noid light and check

are you getting spark?

 

im getting electricity up to the injectors car will start and run if u put gas into the throttle body and it will stay running if u pump the gas alot.
i wonder if i need new injectors or if its in the computer

 

does your fuel pump have a pressure regulator? if so turn the pressure up to about 6 and give er a try

 

ya i have enough fuel pressure ive eliminated everything it could be from fuel delivery problems to sensors and vacuum leaks egr valve and the ecu so i have confirmed that the problem is VATS
how do u check the chip in the key?
how do u disarm vats?
are there any proms out there that eliminat vats?
is there a wiring schematic of vats?
how do u bipass vats?

 

the easiest way it to have a prom burnt that eliminates vats

but that does not sound like your problem

lets just make sure that you have the pulsed ground that is sent to the injectors by the computer

you need a noid light to make this diagnosis

the reason that I say is the car should not run on when you feather the gas for any lenth of time after the initial gas you put down the tb is used

pull a plug and see if they are wet at all

also try unplugging one injector at a time and starting it

it is possible that you have a injector grounding out and disrupting the whole batch of fuel injectors

if it comes down to vats and you dont want to hack into the wiring harness with a vats eliminator module

get your chip reburnt

 

unplugging the injectors didnt do anything and the reason i think it is vats is because the engine wont crank with the key i have to jump the starter

 

get a prom burnt

I would have to look through my posts to find the guy who did mine for around 50 bucks

 

alright do u believe vats is the problem

 

Ignition switch or the Clutch switch.

 

i had the clutch switch checked and it is good the ignition switch im gonna guess is good because i can here the relay clicking when i turn the key to crank the motor i can only jump the starter and even then the car wont start
