Injector problem or fuel issue ### HELP

[ChiTownHussla]

Hi guys I was having trouble with my old injectors because the one on the passenger most side was not firing it looked like. The way I tested for this was to pull the spark plug wire out one at a time. When I did this for the other three the car would stumble a bit, but when I did the last one (pass side) the car acted the same. I changed the injectors to some 550 RC ones I bought from a member on here months ago. I oiled up the rubber stuff and plugged in. That ran fine for a week, but yesterday I went to do a valve cover gasket and It was running fine before that. I took it all apart again this morning to see whats up, and it looks like my 2 on the pass side were not firing properly.

My question is , should there be fuel in the rail when I disconnect the big hose on the diver side? There wasnt really too much pressure either. It didnt FLY OUT like I thought it would. its like the fuel was just staying in the rail for some reason. The injectors were pulsing I felt it when the car did start for like 2 min. IDK what it can be , ### HELP

Don't take this offensive but if you have no idea of what you're doing, don't play with the fuel system. I seen a few cars go up in flames because of fuel leaks. First off, your spark plug wire has nothing to do with injectors, the ecu pulses the injectors. Something as simple as a faulty fuel injector harness plug could cause an injector to not pulse correctly.
Its normal for fuel to be in the fuel rail when the motor is not running; The pressure regulator only allow fuel to return to the tank when its set pressure is exceeded.

OK thanks for the advice. I did actually set the car on fire. I put it out and put itall back. luckily nothing happened. It burned for like 5 seconds then I doused with water. Turns out my buddy or I switched 1 wire for the spark plug wires. Simple fix. Thanks
