    97 454 L29 Long Crank

    10-4, did not think about that. I’ll give it another try. I’m gonna have to get someone to help me. I want to try to leave any clamp completely off and then turn the key on, let the pump prime and when it shuts off then put clamps on to completely block it to see what happens. @someotherguy I...

    97 454 L29 Long Crank

    So here are the results... scratching my head a little. I went back to the manual as @Schurkey suggested and followed the steps for testing the fuel system. The first thing I noticed it said to do different than I had done was monitor the fuel pressure with the fuel pump on. I had just had the...

    97 454 L29 Long Crank

    You mentioned, "Pinch off the return line". Where do you do this at? Can I do this back at the tank or do I need to do this up near the engine? Also, that FPR is equivalent to what I installed: Delphi interchanable: OEM / Interchange Numbers: 12499841, 12555909, 12574986, 17113517, 17113536...

    97 454 L29 Long Crank

    I'm gonna start with replacing the fuel pump and go from there. I believe with they injectors holding 41-42 PSI and the pump rated for 42PSI they aren't the problem. The margin of error here could be in the gauge or my lack of knowledge in doing a proper test. I mean I can barley squeeze the...

    97 454 L29 Long Crank

    Thank you for your information. I don't know how to tag multiple people in one post but to answer your question and @Spareparts question, here is the fuel pressure test I preformed. Your opinions would be greatly appreciated, but I think I have the wrong fuel pump.... Fuel pressure test: Key...

    97 454 L29 Long Crank

    I am going to run the checks this evening. Can you confirm what fuel pressure should be? I am starting to wonder if I installed the correct fuel pump. The old fuel pump had started to get to where it whined and I was worried it would go out. I ordered all the parts off RockAuto and when I got...

    97 454 L29 Long Crank

    I will say I believe it is, it cranks over "strong" or however you want to put it. It doesn't seem like it is struggling. As far as corrosion they are good in clean. The positive side has that spacer in-between the two hot wires that I replaced last year. However, this is def something I haven't...

    97 454 L29 Long Crank

    My truck fires up good when cold, but when it's hot it can have a long crank after sitting. If you turn the truck off then turn the truck back on (within ~10 mins) it fires up immediately, just like when it's cold. If it sits for ~30 mins, then it has a long crank. If you barely give it some gas...

    97 454 L29 Distributor Help....

    I am going to make sure I have fuel and spark when I get home. I didn't have much time this morning but I checked fuel was at the rail. It just cranks and then kind of chugs a little if I give some gas, never really fires.

    97 454 L29 Distributor Help....

    Alright, got it put back together and NOPE it did not run.... I have a question.. Mechanically I know I got the distributor back in the same position on the camshaft. For the OEM distributor retain clip it is designed to allow the distributor to be rotated - the one I thought was broke when...

    97 454 L29 Distributor Help....

    To get the distributor to seat fully, I have to turn it quite a bit and it is off from where I had it originally I am really not sure where to go from here. Since I haven't turned the engine over should I install it where it seats? Should I install it in the position it was and put the new...

    97 454 L29 Distributor Help....

    In the tear down of replacing injectors I have ran into an issue with my distributor... The truck was running fine before this, just had the long start issue after it was warm. I was hoping to be able to just pull the distributor out and put it back in the exact same position. Before I pulled...

    98 k1500 VCM swap advice

    What Shift Firmness did you go with? I've been reading about the TM Reduction - (watched this video: ) What TM Reduction was tearing it up? 50%, 75%, or 100%? I am pretty sure my truck has a 4L80E (K3500 7.4L)

    That is what I am leaning towards, for the cost I can't find any justification that says five 0 is worth it.... The precisionauto have good reviews too.... I think it's a coin flip between the two

    Thank you, I overlooked this.... The Five0 Injectors 4bar rating? I don't see anything called out about it on their page. I can email them and confirm. https://www.gmt400.com/threads/the-official-vortec-454-info-thread.50576/ Mangonesailor says that 4bar = 58.8psi (Factory pressure) 19lbm/hr...

    The Stupid Engine Questions Thread

    I have a 97 K3500 454. The right side of the engine bay has hook ups for another battery. Typically this is where the chevy storage box is. What is this second battery for and what does it power? There is a black canister(?) next to this that I am not sure what it is. It has two openings...
