Ok, so Im new to Elantras but not cars. It all started off with crystalized ethenol in my gas tank clogging up my injectors. Oh, I have a 2000 Elantra Sedan GLS 2.0 manual, 15x,xxx miles. Car sat for 3 years or so until I got a hold of it. After I started driving it the car became sluggish and check engine light flashed. After weeks of investigation I discovered a mound of brown power-ish stuff on top of injectors. Cleaned them, re installed and after a few days the problenm started back. Looked at the tank and saw that it was almost fulled covered with brown crap. So until I got the money for a new tank I had to remove the injectors and clean every few days. The taking off and putting back on I wore the banjo bolt till it broke. OK, IM SCREWED!!! No one has it listed cant get to the junk yard. CRAP!!! So, I have a fuel rail from an Audi TT laying around. So I mad it fit, cut hoses and all. Only problem, cant bolt it down, different mounting holes. So I did what I had to and tied it down. Every so ofter I had to check it because the injectors would slip out and leaek gas. One night, I checked eveything and drove home. Before getting home I decided to pull into a gas station to check just so I can feel good bout it. When I pull in I see my reflection from another car and, CRAP!!!! ORANGE GLOW FROM UNDERNEATH MY CAR!!!!!!!!!!!!!! It leaked and caught fire. I hurried up and put the fire out. It burnted a few wires, AC belt and timing cover. So heres my problem. I said screw the AC belt and timing cover for right now, I got to get the car back on the road. I rewired the injector harness and all the wires in that loom that goes to the firewall, the best I could. I know the wires there are for injectors, AC compressor, cam sensor, crankshaft sensor?, and a ground on the IM. Anything else on that loom? Does anyone have a wire diagram for those wires? After rewiring everything I attempted to crank the car. The engine turned but no fire. I disconnected the fuel line and tried again, no fuel was pumping out. The fuel pump isnt too old. I was thinking the fuel pump relay but dont want to spend any unessisary money, I have a newborn baby and a wife to support. Could any of the wires burnt affect the fuel pump? I tested the wires to the pump to the best of my ability(battery dead so had to have another vehicle connected to my car) and had no power to pump, I think I did have ground. Im tired of messing with this and spending usless money. The is my father-in-laws car and he plans on giving me the car if I can fix it. I have no other source of transportation and need this fixed ASAP. I know alot about mechanical work.

Ok so I put in a new fuel pump relay and nothing. Ran a jumper wire to the pump and it runs just fine. Hooked everything up including the jumper wire the motor would not start. It jist kept turning and turning.

The light has been on for a while, but of course with my luck it wont connect to any reader. Must be a messed up wire between obd port and ecu. I just got done working on it more. Found out my fuel pump problem was a weird looking fuse under the hood labled ECU was blown. Switched it with the one for power windows since my window motors don't work. It did crank up but now runs extreamly rough. I checked my wires and discovered that the 4th(from pass side to driver side) injector wasn't getting a ground. Fixed that and tried again and still nothing. When it caught fire all the injector wires burnt and the protective rubber melted so I had to get new injector connectors and wires. There wasn't a elantra at the local bone yard so I pulled them off a 2000 Accent and did the best I could with matching wires. Did I hook a wire to the wrong injector? Also the injectors are from the Accent too, plus the throttle cable. Every once in a while it will rev high but I don't think I have the idle right( where the cable mounts to the bracket and has the two nuts on it. Still, it runs very rough and will cut off if I let it idle, after running like a 1 legged dog for a few seconds. Can anyone look at their injector wires and tell me the color of the + cable going to each started from the pass. side? The colors from the Accent don't line up but I do know the ground for each cable is the red wire, that part wasn't burnt too bad so I could see the red on each connector. I must fix this tonight so I can drive to work tomorrow so please hurry, LOL!!!

What about the idle speed control actuator? If that is not wired right could it mess me up? When I try to drive the car, I slowly let off the clutch and it will go but wont accel when I mash the gas.

Idle Speed Actuator only controls the Idle. Plugged Cat would cause an engine not rev up. If I remember correctly, You can check that with a Vacuum Gauge.

First, will the accent injectors work? Second, can miss wiring the injectors to cause it to run rough or should it not run at all? Third, would a miss wired IAC actuator cause a problem? Fourth, would a bad cam pos. sensor cause it to run bad or not at all? Could I have wired something wrong? I didn't rewire the AC compressor, replace the compressor belt and didn't replace the timing cover for now. I just need to drive it to work(mechanic shop).

I know with several cars I used to own, The Fuel Injectors are wired up like Christmas Lights. One Positive comes out of the ECM. Wired to all the Injectors. Now the Ground wires are Separately wired to the ECM. The ECM switches the Grounds to activate the Injectors. COPS work the same way.

I wired them all to have a common ground. The car cranks just runs like crap. I'm pretty sure that if they had a common positive then I wouldn't get any cranking. Or would I?

Injectors are Separate from the Starter Circuit. Haynes publishes a book for your model. Unfortunately, not for my GS Coupe
