I have a 93 GMC Suburban and I got it from my dad he replaced the fuel lines and put new fuel injectors in it and it ran fine I got it today and it ran great I went to play pool and she I came out my truck...


Were the new fuel lines the same size as the originals? What about bends in the lines? Is the line kinked (closed off) anywhere? Did he use a tubing bender to make all the bends rounded?

Trans sticks in 2nd gear


"...he had to put hi foot on the gas pedal several times..." I do not understand what this means, but does it still fine? If it is then you likely had a stuck shift valve, but why is the valve stuck? Is the valve body contaminated as a result of the trans "coming apart". If it is still not shifting out of second gear then you may have a 3-4 clutch problem, which is a very common failure and requires overhaul to correct it.

Dies when shifted into gear


May be having problems with engine vacuum leaking. Pull the large hose going to the vacuum operated brake booster and block off the hose end with a cork or other plug. Start the engine and see if it runs more smoothly. Set the emergency brake and put in gear--does it idle smoothly? If so, then you likely have a bad vacuum leak within the booster unit. Restore the vacuum hose to the cylinder and arrange to replace the cylinder.

1999 Gmc Sierra has no power


Sounds like the fuel supply is inadequate. Check for a plugged fuel filter, or possibly the fuel pump is losing pressure. I had a 93 Chevy V6 that acted the same way, and after checking everything else I replaced the fuel pump, which solved the problem.
