    STILL chasing hard start....

    That it does. I just couldn't get the issue to show itself while at a shop, it drove me crazy!

    STILL chasing hard start....

    ^ seems to be the winner. Truck finally acted up for a shop and they tracked it down to cap and rotor. Although every now and then she stumbles at start (had the press the throttle to start at one point and ran rough for a few seconds), almost like there's water in the fuel... running a bottle...

    Fuel pressure regulator?

    So appears that there was some corrosion/"carbon trails" in the distributor- new cap and rotor has her firing up in proper time! Next fun issue that's shown up is where she would stumble a little at first still presents itself- to the point I actually had to feather the gas pedal to even get her...

    Fuel pressure regulator?

    Still randomly happens after at least a couple days of sitting, can't reproduce it consistently to really diagnose. Have a coolant temp sensor on the way to throw at it

    STILL chasing hard start....

    Would checking those be dependent on actually catching it while it struggles, or do you think they'd show themselves any time? I haven't figured out how to replicate it quite yet... hit or miss after a few days. Also, on occassion it seems to stumble a bit on startup- just for a couple seconds...

    STILL chasing hard start....

    Had posted a while back about what was assumed to be fuel pressure regulator issues.... turned into now having replaced fuel tank, pump (twice, did it myself then took it to a shop for same issue and they said pressure was low so had them do it 8 months after I did), rear fuel lines(that run...

    Fuel pressure regulator?

    Well after installing a Delco spider injector (MPFI) and still having some of a stumble when sitting. Scratched my head enough and took it to a shop to diagnose (local Chevy dealer). They called back saying that it's not making enough pressure and want to start with fuel pump (which is a new...

    Fuel pressure regulator?

    Will let you know- I'm almost mobile enough to get started on this. I will say that my issue seems a little opposite of yours- once it's warm it tends to act better at least, issues come up with sitting for "short" (within a week) periods of time

    Fuel pressure regulator?

    No specific resolution yet- I've ordered one of the new units, just working on getting around to it as I'm inconveniently on crutches at the moment. My issue did go from showing up at that ~week timeframe to just a couple days now

    Fuel pressure regulator?

    My bad. probably a helpful place to start ha. It's a '97 5.7 Vortec, so yes to the spider. Was in there a couple months ago for the FPR

    Fuel pressure regulator?

    Yes Vortec The gaskets for the upper yes, the injection unit no. A likely candidate to where my 'leak' is?

    Fuel pressure regulator?

    So started back near beginning of summer- truck would sit for a while and not start until a full 30-45 seconds into cranking. Was pulling brakes apart at the time so I figured might as well- ended up doing fuel tank, pump, the fuel lines that follow the frame rail, and then fuel pressure reg and...
