ok so me and my buddy are working on a 90 camaro with a 3.1 auto tranni. the engine is bone stock and we picked it up for free from a buddy of his. as of right now its throwing a code 12 and 43. last wensday, we had it started on its own but running only on 4 cylinders, and when you gave it gas it would just shut off. now as of friday, it wouldnt start on gas anymore but would start on starting fluid run for mayb 30 seconds and shut off. yesterday after working on it, we now know we have spark and we have fuel in the rail.

so my question is, does anyone think they know what the problem might be? and since this may also be important the car was sitting for 2 1/2 years not running. and the fuel rail and plugs and wires are brand new.

 

for starters id get new gas in there

 

we did that. the tank was emptied and we put in new gas.

 

change the fuel filter if you havent already. the gas tank could of accumulated crap from it just sitting there for over 2 years, and now clogged the fuel filter

 

good idea, do u know if theres any way to test the injectors if its not the fuel filter?

 

go to a shop try to find stuff called 44k it will clena your injectors and engine liek you wouldnt believe. its so lethal they don't sell it in stores. the shop has to drop it in ur gas for u. after that an oil flush/change wouldn't hurt check timing and spark plugs/wires and new distributor cap rotor and coil would be good too. not saying it will help your problem but if your only running 4 cylinders wouldn't be a bad idea to replace a few ignition parts for about 100-150 all together.

let us know if any of this helps

 

well now he desided to get rid of it for 600 bucks anyways not running. o well. thanks for the help though ill keep all that in mind if i run nto something like this again
