Well. The last place I look for problems is the injectors simply because I've never had problems with TBI. And it isn't easy to crank the engine and look at them spray gas at the same time. So. I replaced plug wires, plugs, distributor cap and rotor. I got two minutes of run time before it stalled out and wouldnt run, blue smoke. Obviously flooded. I had opened the throttle and looked down the throat of my TBI, and well, there is standing gasoline in there just about up to the butterflies.
I had someone crank it while I looked at the injectors in operation. Well hell, both injectors are spraying huge amounts of gasoline during cranking. It took about one second for both injectors to spray fuel alternating back and forth one time each, but each time one sprayed, it was easily 4 to 6 fluid ounces of gasoline in what, half a second's time? I didn't even know those injectors were capable of shooting so much fuel!
So it explains why my spark plugs are soaking wet with gasoline when I pull them out. It explains why its flooding and not starting.
First thing I am going to do in the morning is pick up the TBI kit from Napa. But I want to know if I am on the right track.
I figure the problem has to be with the TBI. I've tested every last ground and sensor that I could reach wiring for.
Is there ANYTHING else that could be causing it? Or is it most likely the injectors being messed up like I figure?
And, I dont know if this is related to the problem at all, probably not. But when I try to access the OBD, no codes flash, but there is a clicking coming from apparently inside the TBI assembly somewhere until I unhook the code reader.
I can't afford to replace sensors AND rebuild the TBI right now, but I wanted to get as much of an expert opinion as possible before I attempt to do anything with it. I've been down this road before, replacing parts until it is fixed, and I'd rather get it right the first time now.
have the same problem?
