    Truck's stumbling on cold start, thinking it might be a fuel pump issue.

    Okay, I put a new mechanical pump on and that seems to have fixed the issue. We'll see if there are any starting issues tomorrow. I found a boost leak too, a loose hose clamp from the turbo to the housing on the intake, so it definitely is pushing more power. I have a couple questions. 1A.) Do...

    Shoot. I assumed the 48" referred to vertical lift, not lateral. Walbro's website says the following regarding that pump "Self-Priming (Dry Lift) of more than 48" (120 cm)" Skid plate is a good idea. I was hoping to kick the larger, much more time consuming job of dropping that tank or...

    Truck's stumbling on cold start, thinking it might be a fuel pump issue.

    Thank you. I had to run to NAPA to warranty my brake booster so I picked up a mechanical fuel pump while there. I haven't dug into how to install it yet but I figure it has to be pretty simple. Regarding the electric pump, I would just bypass the manual pump. I'm wondering if I can leave the...

    Truck's stumbling on cold start, thinking it might be a fuel pump issue.

    This issue started about a month ago, where it would catch but take a few seconds of throttle to the floor to get up to normal fast idle speed on a cold start. Now it's at the point where this afternoon the truck won't start. I believe the traditional "air intrusion" symptoms are it fires off...

    Hmm, fair enough. That's the same link I purchased mine from. Our boiling point is around 195*F here, which is why I gave it a little time. Might give it a go in some cooking oil on the stove.

    Well, here's a little report back and a little PSA. I had some time today to work on that thermostat but I figured I'd boil the new one first to make sure there are no issues. This new one doesn't appear to open at all even after sitting in boiling water for 5 minutes. I purchased them both...

    Thanks for the information! I'm debating pulling this replacement thermostat and checking it. Probably best to do, however, after reading that other thread that's going on right now I'm starting to wondering if my old thermostat was causing my truck to warm up abnormally fast in cold...

    Okay, I picked up the laser temp gauge today and did a little test. After driving around for about 25 minutes I pulled it into the garage, turned it off, and shot the upper radiator hose. Reading about 140*F. I'm going to guess the thermostat is stuck open. I have a replacement Motorcraft...

    Apologies, forgot to include the other information on my truck. I do have a pyrometer that came with my turbo kit that is installed. Climbing a medium grade at highway speeds I sit around 600*F on the EGT gauge, cruising is closer to 300*F. Temps on the dash coolant gauge are pretty steady...

    Will order one, nearest harbor freight is like 2 hours away. I have some semi cheap gauges on order for coolant temp and oil pressure, I will install those once they get here. Also have another thermostat coming in tomorrow, however, I'll probably get the gauges on first and see what they say...

    thanks for the clarification. Yeah, I'm going to get a coolant temp and oil pressure gauge on it.

    Engine Running Cold

    It was usually fine last summer however I think the thermostat was stuck open for about a month as there was a little while there is was running cooler than normal (both on the gauge, by feel, and I think by power). Mind clarifying the whole leaving the radiator cap loose thing for me? Always...

    1.) Yeah, I'm going to test this thermostat when I pull it out. I'll probably wait for the new one to show up so I don't have the truck in pieces again. 2.) I'm wondering if that cold circulation could be sufficient to keep the engine from reaching temperature?

    Yeah, I have boost and pyrometer. Could use coolant temp and oil pressure.
