Won't start

[hollywood_716]

I have notice for the past few weeks my truck seemed sluggish. I don't drive it much lately. I had someone look at it and they said the cats were probably bad. Well I parked it and didn't drive it for about 2 weeks and now it won't start. It will crank and idle like crap for 3-5 seconds and dies. Sometimes 10 seconds. Any ideas ?

That's tough to diagnose maybe someone will be able to help. Year? Miles? Has the fuel filter been changed?

2003 160,000 i am not sure if it was i will check

When you turn your key to the on position(not cranking) do you hear the buzz from the fuel pump ? last fuel pump i replaced it was only putting out half the psi necessary to run...so it would start but not run much over idle then die.

 

[hollywood_716]

i do hear it

now i would wonder what your fuel pressure is on the rail ?

I'm gonna check tomorrow. I was wondering about that. What's good psi? Thanks

55-60 psi.....ish

Well. Bad news No fuel pressure. Good news. Fuel level sensor is bad. Said I had a quarter tank but was empty. Filled it up and psi shot right to 60 and fired right up. Thanks for all your help!
