2006 Jeep liberty Sport 3.7L. I already replaced fuel pump (which burnt out). I turn the key in the ignition and the Jeep will crank but not turn over. I usually have to turn the key 90% of the way to fill the fuel lines (or something), turn the key back off ( do this a couple of times), then turn the key to crank while I pump the throttle to start the Jeep. What gives? My Jeep is literally falling apart, but this it a big issue and I don't have a lot of money. I'm sure I can do the repair myself but I don't know what the problem is. Please help.
Yeah, once it's started it runs good. I've read on this forum before about a broken "check valve" causing the fuel to drain back into the gas take when the vehicle is turned off. But I'm not sure where this check valve might be. Also, in another thread someone mentioned an issue with the position of the Libertys' fuel filter, and needing to get an upgrade kit. Sounds $$$$ to me. What do you guys thinks?
Could be .. if it is the check valve, you will see the fuel pressure drop once the vehicle is turned off. I would just check the fuel pressure to ensure it's really a fuel problem before spending any time or money on guessing and blindly replacing parts. I read something online recently about a guy using a bike pump to check fuel pressure, although I didn't read too closely on how he did it. Some parts stores will loan/rent tools, so see if they have a fuel pressure guage you can use. Or just find a local garage and slip the guy a $20 check it for you.
