    hi there. things have started to slow down a bit for me. Tired a look at my old trucks rust away. been about a year to three years since I have done anything with these. So first up is a 98 Chevy C 1500. I had a bad front end collision wiped out the front. That's all replace. Finally after a lot of time I got the airbags in. Before I did the airbags I ran for little while seem to run great. Now it seems like it wants to starts up for a second or two and shuts off. Every time. The fuel pump was new about four years ago. That truck has been sitting two years now.I don't hear the fuel pump running.

    Any advice on this? Going to be taking a look at this in a few hours thanks guys

    no codes.. fuel is about 2 years old. had conditioner in it. when I first ran the truck after I got the front and back on it ran great. I ran most of the old fuel out. Put in about 6 gallons of fresh fuel.

    Fuel filter?

    It would be nice to have a fuel pressure gauge on it to confirm the pressure when it dies.

    there's a shraeder (sp?) valve back on the hardline near the firewall that you can hook a gauge onto. Also, the fuel pump relay could be suspect so keep that in mind before you go dropping the tank.

    good evening, finally got to put some time into this truck. Got it started seems to run pretty good idles a little high. I replaced the airbags. The airbag light is still on though. Not sure why yet. Next few days going to give it a tuneup and change the oil in the motor transmission and axle. Have any ideas about the airbag light? Thanks
