I have a 93 its having starting issues , It will start on starting fluid, new pump, rubber fuel lines to pump, new filter, new regulator. I hear the pump come on when i turn key on , cycled it about 10 times still no start . Only thing I can think of that is left would be the relay .. But it does come on when you try to start the bronco... At a loss.. HELP !!!!

Check fuel pressure at the fuel rail ... there is a Schrader up there to hook to .

I wouldn't think all injectors clogged at the same time. if a few injectors clogged it should still run?

How did the tank look? Did you have a bunch of junk inside?

since you hear the pump prime ... it is getting power. maybe it is not pumping ... and you got a bad pump?

Did you get the entire unit .. or just the pump? Everything is made in China .... and they suck.

thanks for the input Guys!! Somehow, probably when I installed the new fuel pump, The hoses got reversed and I was pressurizing the return side,, Changed them around She starts right up.. I know Rookie Mistake!! But I found it !!

WOW

I thought those fuel line fittings where different size connectors ... so you could not reverse them?
