Well my 2.3 LX Stang has been great until today. I went to start her and she turns over but doesnt fire. I do not hear the fuel pump prime the system either. I checked the fuses and there all good.
Whats my next step? How do i hot wire the fuel pump to test that or how would i test the fuel pump relay.
Thanks guys

Thanks for the response sleeper. How would i jump the pump from the diagnostic connector? I do have a OBD1 scanner too that will check relays, so im assuming it will check the fuel pump relay too.
Thanks.

One thing i did also notice when trying to crank the car was that the tach needle bounces. I wont be able to hook up my scanner till wednesday to check that relay :(
Now i have another question. Suppose the relay is good (only $17 so i ordered one anyhow), and the fuel pump is bad, how much of a challange is it to drop the tank and replace the pump? Is it possible to do the above with hand tools and regular floor jacks?
So i pulled the codes. It is code 543 - Fuel Pump Secondry Circuit Open.
So, bad relay? My scan tool did not report back that any of the relays are not working, and the car still doesnt start. Still no sound from the fuel pump either. The new relay will be here tomorrow though. I looked in the engine bay to locate it but no luck. Its on the passenger side fender area right?
I think i found it. It looks like its on the passenger of the engine bay. Hopefully this new relay will fix my issue. Ill let you guys know this weekend when i install it.
So another question, which relay is the relay for the fuel pump? I see 4 relays by the passenger side fender and none of them are labeled. My Haynes manual doesnt state which relay is which either. My new relay arrived today and will be installed once i figure out which relay is which.
Well, this search for the relay is becoming really confusing. I looked on the passenger fender to find what looks to be a CCRM. I have read online though that the fuel pump relay is not apart of that CCRM and that its by the MAF sensor or in the passenger side kick panel by the ECC. When i look for the fuel pump relay online, all the Ford parts sites come up with the same 2" sqaure relay.
Before i start to tear the interior out, or pull my air box and all, has anyone changed there fuel pump relay on a 2.3 DIS engine or is it the CCRM after all?
Im guessing i should try calling the dealership too.
