Ok so last night pulled into apt, turned the truck off for tops 45 seconds to open my garage door (key on my truck keyring). Start it back up and the thing would barely run. Gave it some gas and it finaly caught and ran fine the rest of the way into the garage, plenty of throttle, etc. So Came out this morning and it started right up, but as soon as I try to back out it start sputtering and hesitating. Seems like fuel to me.. Symptoms: - Idles Fine most of the time - Any sort of quick throttle nearly kills it - If throttle is applied VERY slowely it will increase RPM's fine, no coughs or sputters - When I tried driving it this morning it caughs and sputters, sometimes runs fine for a quick second, then starts dying again, seems like intermitent fuel pressure? - No CEL Things I looked at so far: - Changed the fuel filter - nothing - Pulled regulator and screen is clean, no fuel in vac line Ideas already rolling round my nogin: - Fuel Pump? Most liekly at this point, but have no way of testing pressure unless I get it somewhere, but if I just turn the key on the system does presurize (pulled reg and gave it a quick turn and fuel spurted fine) - Fuel Pressure Reg bad? Gonna go price it out - Wouldn't think plugs and wires since it happened all of a sudden, but have new plugs in hand and am going to order new wires. - Dirty MAF? Gonna grab some cleaner in a bit - If a new reg doesnt work I'm working on getting my hands on a code reader (I know, would be best to have codes in hand already, but only been workin on it a few hours) Am I missing anything obvious?
