Default Fuel Pump Replacement Suggestion/Warm Start Problems

Hello All,
I will be doing some fuel system troubleshooting once I get the rail adapter. I have been fighting the dreaded warm start problem for a few years now. I read through all the posts on that issue and saw that replacing the fuel pump did not fix the problem for anyone suffering the same problem. My car does have close to 100K miles and if my troubleshooting indicates it's bad, I wanted to get some opinions on a replacement. I have seen quite a range in price from 150 on ebay to more than 700 in performance shops. I am just looking for something that does the job, I don't track the car and will most likely be getting rid of it relatively soon. Based on that, can anyone suggest a reliable, relatively inexpensive replacement? Thanks!!!!!

I'm not sure if you referenced my warm start problem thread but it wasn't fixed by replacing just the fuel pump motor. After I replaced the entire fuel pump module, which includes the pressure regulator, problem solved. I therefore attribute it to the fuel pressure regulator.

Mine would continuously crank when warm/hot and sometimes not start at all. Always fired fine when cold. If you do anything in tank, replace the plastic top hat with the CJ metal unit, heck it may already be broken.

Shop around for the module if it comes to that, ebay, amazon, rockauto, and Carid have the best prices IMO. Only buy a Nissan module.
