I have a 04 Ram 1500. I shut it off. Then went to start it

Customer Question

I have a 04 Ram 1500. I shut it off. Then went to start it again. It would not start. I then did some research. I ended up changing the throttle body and fuel pump. It still would not run. I left it alone for a few days and it started and ran for a few months now. Now here I am again with it not running. It seems that the fuel pump is not turning on. what can cause this?

Check fuse 17 for power

Customer: replied 9 months ago.
ok I will do that. Give me a little bit to get back to you.
Expert:  Tool Hut replied 9 months ago.

Please check it with a test light

Customer: replied 9 months ago.
check both fuel pump fuse and relay. both have power.
Expert:  Tool Hut replied 9 months ago.

The relay should have 2 powers and a ground

Expert:  Tool Hut replied 9 months ago.

The bottom of relay has numbers on it. Try crossing 30 and 87 with a fused jumper wire and see if the pump runs.

Customer: replied 9 months ago.
ok both powers are there. I jumped 30&87 and still nothing.
Customer: replied 9 months ago.
my truck is a little was away from where im at so this is why it may take a bit to do the things you are suggesting.
Expert:  Tool Hut replied 9 months ago.

If you have power at the relay and you have jumped the relay and no pressure it is either a bad ground, broken wire or a bad pump. Can you check for power and ground at fuel pump connector when the relay is jumped?

Customer: replied 9 months ago.
ok I will try that. This will take me a little while. I'll have to drop the gas tank down.
Expert:  Tool Hut replied 9 months ago.

OK. Let me know results

Customer: replied 9 months ago.
Well I have run out of time that I am able to deal with this myself. while I had came to the same conclusion before talking with you. Your advice was spot on and gave me a few more things to check. I will give you a good report. You should get paid for the help you gave me. Thank you.
