no fuel pressure-help

[Dan2060]

Hi All,
I have a 2004 xstar and I was trying to start it last week to change the oil. Well, it would turn over, but nothing else. Normally, when the key is turned to the right you hear a buzz (which I believe is the fuel pump) shortly after that the fuel guage registers the amount of fuel and then your good to go. I'm not getting this sequence.

I thought is was the fuel pump and I have an extra, so I plugged in the brand new one (didn't want to take off all the allen screws and replace just yet). I turned the key thinking that if this was the problem at least the new pump should make some noise. Is this correct?
Well, no noise from the new one.

I then looked at the fuses under the dashboard and pressed all the buttons to reset them all ( I didn't see one specifically for the fuel system). No luck.

Where do I go next?

Breakers at the back of the engine. One is for at fuel pump.

Does your engine have a fuel pump relay?

Not sure if it cuts off the fuel pump but check your kill switch. If not I'd say maybe bad relay. Do you have 12 volts at the connector?

+1 on this... safety lanyard a likely suspect...

I'm with Mike on this one. I was actually referencing the relays on the back of the engine. There should be 3 of them. One controls the fuel pump and has been documented on this forum as a source for this type of problem.

Since you've plugged in another pump and it didn't make any noise we can assume there is no power at the connector. Regardless it would probably be best to check for voltage with a meter anyway and also check condition of the wires and connectors all the way back to the relay.

Why don't you trouble shoot put a positive 12v to the pos. Side of the fuel pump if it turns on fuel pump is good next put power to the relay if it still turns on the pump from there its in the wires before that

Thanks guys, It may not be until next weekend, but I'll check out the ideas and let you guys know.

[Dan2060]

ok looked all over the engine and don't see breakers or a fuel relay. I've attached a picture of my engine. Can you guys help me out

what's under this square cover... ?

not sure what is under this cover or how your model engine is wired.
