So I've been boggling over this for WEEKS knowing that my symptoms could be a number of things
, but tonight I think I finally figured it out. I always thought it was the fuel pump, but I was hoping in the back of my head that it was something cheaper. Instead of having a shop do a full diagnostic for 90 bucks, I decided to pick up a $20 fuel pressure guage at Harbor Freights. Sure enough, my fuel pressure was only at 27 psi the first time I tested it (30 the second time after it warmed up) Here are the other symptoms:
-I hear no noise when I turn the key (as in I dont hear the fuel pump turning on)
-The jeep loses power when given too much gas, if you feather it, it doesnt bog.
-Even when feathering it will only seem to cooperate between 2100 and 2900 rpms
-kind of bad gas mileage (but I think thats just the 4.0 showing off)
Any thoughts from you guys before I fork out the money for a new pump assembly?
I found a really cheap Airtex assembly on Amazon for half the price of Autozone, heres the link
Airtex E7115MN Fuel Pump Module Assembly : Amazon.com : Automotive
I know it being cheap is kind of sketchy, but it's being sold by Amazon itself, do you think I could print this out and bring it to Autozone or Advance Auto Parts for a price check? The part numbers check out!
