    Only starts after block heater is plugged in

    I've removed and installed the upper intake and spider so many times I'm even doing it in my sleep lol. Seems to be running like it should. With the MPFI spider, the idle is so smooth now...barely tell it's running from inside the cab. Moral of the story....DO NOT PUT DIESEL IN YOUR GAS TRUCK!

    I read somewhere on this forum that you will see lower fuel pressure after installing the MPFI spider. I got a reading of 55 psi that slowly dropped to 50 psi after a couple minutes. Does this sound about right???

    I didn't check before I tore everything apart. I will tonight once everything is buttoned up again.

    New spark plugs, same result. Misfires, running rough, strong smell of gasoline. Pulled it all apart again last night just to make sure everything was where it should be. Pulled the brand new spider and everything looks to be ok. One thing, however, is that there was no fuel pressure to...

    Finally got the upgraded spider installed. The intake was wet on the back half so something was definitely leaking. Buttoned everything up and now I'm getting a P0300 code (random misfire) and runs super rough. Pulled the spark plugs (didn't look too bad but smelled like diesel still) and...

    After a week of being -30 to -40C, and then Christmas, I am finally going to be replacing the spider injection with a new and upgraded MFI spider. After talking to a couple mechanics about the symptoms I'm having, they keep going back to a possible clogged/gummed up injector(s). It now takes 4...

    My bad. It is the vehicle security I turned off...VATS...NOT VSS. :)

    I disabled the passlock as well as the downstream O2 sensors...that's it but I will go back to stock and see what happens.

    If I can't figure it out by next Tuesday it's going to be dropped off at my mechanic. I do have HPTuners. I've done a bit of logging in the past but could that show anything of interest or is an actual automotive tech scanner be needed?

    And.....I'm back to square one. Truck sitting outside for 5 hours and same no start as before. I'm at a total loss now...damn it.

    That's what had me scratching my head. Well this morning it was -21C/-35C (-6F/-31F) with the wind chill.

    Well it seems it was a failing/failed coolant temp sensor. Checked the resistance with a Fluke meter and got a reading of 3400 ohms. I'm guessing that's not ideal. Left the truck unplugged for 5 hours in -20c temps and fired right up with no hesitation. Would never have guessed that a new...

    I'll grab my MM and see what I get for a reading. It's not that expensive so I might just replace it anyway. Thanks for the info guys. I'll report back.

    That's the thing...it seems every gas station is different. At one station yellow is diesel and red is gasoline. At another, diesel is black and gasoline is green. One would think that there would be some consistency to help avoid dumba$$es like me.
