2005 chevy Sububan 5.3L 4 WD w/Flex Fuel. For the 4 wks it has been hard starting. It doesn't stall, once I turn the key to start it if I don't hit the gas it won't start. Once I hit the gas the RPMS bottom out and then if I continue to rev the gas it stays running. I beleive it is idling low but I was told that's normal due to flex fuel. I just replaced the battery since my truck dead every 5 days but the battery was the original so it was old. I also have tried turning the key in the on position and waiting a few minutes and then starting it that seems to work. I am aware that the fuel filter is in the tank so I was planning on buying cans of sea foam and seeing if that works. It has 48,000.00 miles.

Make sure you have the correct factory Honda starter in your car , if its an aftermarket starter they may have replaced with cheapo starter,sometime the teeth that engauge starter to your flexplate will not mesh properly,because there different,causing the flex plate to fail. I had the same problem. I went thru 2 before I found this out..Hope this helps.
Please rember to rate me on my help. Thankyou!

Some GM products also incorporate the oil sender switch into that circuit for fuel pump, so that in case of an accident, engine shuts off, oil pressure drops, in turn, shuts off power to fuel pump. May be worth a look at what your getting for oil pressure, as well as checking switch/sender.

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

Advance auto and auto zone sell just the flex pipe. You will need to have someone cut the old one out and weld the new one in. costs about $20 for part vs $300 for pipew/catalitic converter attached.

Had a similar problem and turned out to be a fuel regualtor.
Be careful with the little o-ring. Tricky little devil.
There may be residual pressure in the line so be careful you don't take a shower in gasioline.

It was hard to start after warm up. Rough idle until driving. Then on shut off it was hard to start.
