Truck Help Needed
I know it's not an LS1 but you guys seem to be awesome to help out anyway.
I have a 2001 Chevy Silverado
Earlier in the year she had a starting issues. I changed the plugs and she's been running fine for months, until this morning. She'll turn over fine and have 1 good surge where it sounds like it's going to start right up but never takes. If you keep the pedal down or pump it while starting she seems to die quicker. So if anything it's flooding and getting plenty of fuel.
I had a fuel pressure gauge hooked up earlier when this same issues started. The pressure when off with the key on was around 50-60 (excuse my memory here but this could be a bit off). When doing the second test, which i beleive is with the key and engine on, I was supposed to see around a 10 PSI drop, I only saw about 5 psi difference.
I didn't think much of it at the time as she was running with just new plugs, but could this be an issue that's fouling the plugs?
ATM i'm thinking to replace the fuel pressure reg, plugs (thank good this isn't on my LS1), and probably wires also just to be same.
Any opinions, am I on the right track here?Last edited by 2k-Trans; 12-01-2009 at 05:05 AM.

distributorlees ignition with coil packs? I am just guessing here, but I'd try swaping in a new crank sensor, and if you have a replacible filter, put in a new fuel filter

Does have coil packs yes, and the fuel filter was replaced at the start of the year, could have developed an issue but....
Also forgot to add, once she's running she runs well but I have noticed some barley noticeable hesitations at speed

I'd swap out the crank sensor and see if that fixes it

Do you have a check engine light on as well? Could be bad O2 sensors

Is your water temp gauge rite on where its suppose to be? I had a bad water temp sensor one time and it threw no codes. But it thought it was too cold and was causing rich fuel conditions and starting problems.

Water temp seems fine didn't notice any issues last night when coming home.
No SES lights, although i have had the security light up but that was from when it was running fine and is intermittent.
with the Crank sensor, would changing the plugs have temporarily fixed it for a few months. Not to familiar with what this sensor does atm.
