    7.4 vortec fuel issue

    I have the 5.7 V8, I hope you find and solve you issues quickly. Mine was the fuel pump, putting out around 45 PSI, I had it tested, it was also hard starting cold, warm not an issue. I was told that in my model year '98 that it had to be no less than 5 PSI from 60 PSI. If I slowly accelerated...

    Need more heat

    I'm sure he has already checked the coolant level in the radiator, but I have had that happen to me before. But as you suggested, I finally had the intake manifold gasket replaced, that was a few years ago and the fluid lever has stayed constant without the need to add more and have had good...

    The thread for twins

    Just about every truck that is posted is nicer looking than mine (1998), from what I can figure out it started out as a fleet truck in Chicago. I've spent money on the power train but not on the body, one of these days when I close my door, all I will have left is the frame.

    Fuel Pump Bad?

    Yes, very possible. I had trouble cold starting mine for several months, I would have to use ether to start it, with a lot of suggestion as to what might be causing the cold hard start. I was told after I had it fixed that the pump was only putting out 45 PSI and needed 60, give or take a...

    Right front LED turn signal doesn't flash

    Well problem solved, in my case it was that 'multi-function turn signal switch', I took it to that shop, in under 40 minutes he had it replaced and sitting back in front of his business. So far the only thing I haven't had a chance to check out real good is the cruse control but it does seem to...

    Right front LED turn signal doesn't flash

    Glad to hear that, I haven't dug that deep into mine yet because my son will be doing it,maybe. If he doesn't I have a local shop that was highly recommended to me by another shop that I trust. He is going to try to install a new multi-function turn signal switch which hopefully will fix a...

    Right front LED turn signal doesn't flash

    Yeah, like I mentioned, that same LED that won't flash as a turn signal, WILL flash when the 4 way flasher is turned on. I'm thinking my problem is between the stalk and that right front signal, guessing a wire BUT I haven't got around to trying to find the energy to tear into it. Almost 70 so...

    Right front LED turn signal doesn't flash

    No reason for me to mind, maybe if someone has a solution for one of us it might help both. What's that saying, misery loves company...

    Right front LED turn signal doesn't flash

    First I should say my son helped me convert all the turn signal and running lights to LED's and has been working fine until today. So that would be about 2 1/2 years. I should add we changed the flasher to an electronic flasher. When checking the right rear flashes just fine, but the right...

I'm still using the Spyder glass headlight lens, still using the 4 high mod and loving that and I'm liking that LED light bar I have up there, but...

    350 Vortec loosing coolant?

    Mine had an intake gasket leak, very slow but a leak none the less. On mine in the front where I could see (without a lift) it looked like it was 'weeping', you could see a spot on the front that was constantly wet, also the over flow tank would never hold its level. I had that repair done for...

I need to get a newer seat with the seat belt attached to the seat, on my OEM, the lap seat belt doesn't work, just lays there.

    Need a seat with attached seat belt

    I know this has been discussed before but even with using the search I can't find the thread I'm looking for, so sorry for a repeat question. I need to replace the seat I have in my 98 truck with one that has an attached seat belt on the seat, the OEM one is toast, just lays on the carpet. I...
