I would check ECM (Electronic Control Module) Fuse, then pull codes. Codes are easy to pull, all you need is a paperclip. Look for the ALDL (Asmb. Line Data Link) usually under the dash or on the left hand kick panel. It's a rectangular plug set up as a 2 x 8 or 2 x 10. Open the paperclip and jump from A to C (A is either top right or lower left, C is the third one in that row) with the key on and watch the check engine light. The codes are displayed as flashes, i.e. 12 is shown as the one first, a pause then two flashes. Each code is repeated three times. 12 is always shown, it means no distributor signal. Any parts store should look up any others for you. This all assumes you've checked the loom for loose connections and such.

What if you have code P0205 on a 2001 Chevy Malibu?
P0205 means that the PCM detected a fault in the injector 5 or the wiring to the injector. Could be a bad injector number 5. Maybe the wires to the injectors or the PCM is faulty.

On an 1990 S15 GMC is not getting fuel from the injector?
If it is just one injector, it is a bad injector or a problem in the wiring harness or connector for that injector. If it is all of the injectors, it could be a fuse, the entire injector harness, a broken loose or unplugged connector on the injector harness, or the fuel pump or fuel pressure regulator.
How do you trace down a dead fuel injector on a 1991 Chevrolet caprice?
The 91 Caprice is throttle body injected and has 2 fuel injectors mounted above a Rochester throttle body. The easiest way to check for an injector that is not working correctly is to remove the air cleaner assembly, start the car and visually inspect the base of the injectors for a smooth consistent spray pattern. If the pattern is absent or intermittent on both injectors it may indicate a problem elsewhere, the ECM or a maybe a wiring issue or sensor. If it is a single injector that is acting up it could be the injector or a wiring problem to that injector which could be tested with a multimeter.

What besides plugs and wires would cause a miss to cure itself for two weeks and begin missing again in a 1999 Beetle?
Some vehicles have single, throttle body injectors, others have multi-port injection, that uses an injector for each port. If it's an injector problem, the injector could be partially blocked or gummed up. If that's the case, try a little injector cleaner. If that doesn't fix it you may need to have your injectors professionally cleaned. If it's not an injector problem, it could be valve or sparkplug problems. How long since you've change the plugs? You could run a compression test to find out if it's a bad valve.
