A car that sat three years? No way am I going to even try to guess at this, three year old gas and you expect the car to run right? Six month old gas can be a problem.
On that note:
There is no way I'd have allowed that old fuel to run thru those injectors. You can use a pump and pump the tank dry, then attach a fuel pressure test kit to the valve on the end of the fuel rail; you then manually close the fuel pump relay and make the pump run. While you are doing that, have a helper press and hold the release on the fuel pressure test kit and drain the fuel into a can. Once it's all pumped out, put in a gallon or two of new fuel and proceed from there.
I know it's too late for you, but for the next person.... This might seem like a lot of work and time -but it's not. And when you start the car, if it runs rough, you KNOW it's not fuel quality and since you can leave the test kit connected, if it runs rough or won't start, you know right away if you have proper fuel pressure (which is about 58psi, the car will idle down to about 20psi, but if you press the pedal it will die below about 30psi - ask me how I know!)
If you have pressure, you can move on to other items. This way, you gain knowledge of what is going on with the car quickly, which is helpful when things don[t go the way you want them to.
Oh, the OTC5630 kit is $40. Saves you SO MUCH time and frustration. When I meet some guy who "works on cars all the time" but has no fuel pressure test kit, I think: "This guy is thinking at all...." [u] Fuel pressure HAS to be right. Our cars (and most) do not monitor fuel pressure. If your pressure is way low or way high, the ECU has
NO clue. The ECU assumes the pressure is right, if it's not right, it does not compensate for too much or too little fuel - and the car either won't run or wont run right. If you struggle making that car run right, I"d order a test kit and see what you have. I've had three Roadsters, have replaced the fuel pump on two of them, one around 90,000 miles (quit working), my SE at just over 60,000 miles (started leaking).
