Hey guys i have a 97 chevy 1500 silverado 5.7 350 2X4. I put on a new spider a little while ago but i lost the nut that ties down the fuel lines, so i had to wait to get that before i could finish. I finished tonight and when i went to start it, it would spike the rpms to like 4 or 5 thousand then die. My service engine light would come on as it was dieing. I did it a few times thinking maybe it would clear some bad gas out of the engine or something. Also when i started it it started smoking really bad. Do u guys have any clue whats going on? or has this happend to u?
Thanks for the input,
Randy

 

Spider? - diff gears?

 

man..sounds l;ike she may be flooding under there...do you have a pressure gauge to see if the pressure holds?

 

A spider is the fuel injection system on the truck. And no i do not have a fuel pressure gauge. Also i dont see any signs of flooding there isnt any access fuel or anything.

 

Does anyone else have any ideas??

 

wrong nozzle in the wroing holes possibly...or flooded due to a leak underthere,since your seeing black smoke...
how long can you get it to stay running?

 

Well after the RPMs spike it tries to die, but i can push the gas and it will spike the RPMs again. its almost like it idols at 5000 rpm

 

any sucking noises?..that oval gasket that goes around the spider,its verrry easy to slip away

 

Yeah there is a sucking noise. it almost sounds like a supercharger would sound.

 

But would that make it spike its RPMs?
