im a new member with a 1996 k1500 suburban ls!!im glad i found this site because i definetly need some answers on a problem with my sub. First off my when i was driving my sub two weeks ago, i was on the expressway when i just started acting up i would step on the throttle and it would lose power and sound like was not getting fuel as i pulled off the eway, it stumble till i was able to get to a safe spot. now i turn it off and try to start it back up of course it wouldnt start it would crank over but would not fire.
I got it towed back to my house a few days later and started to look over what it could be. i check the ign module,coil(witch i did replaced because coil and coil wire were burnt), then i check the relay which is good, but here when the fun part comes, when i go to check to see if the pump is working, first i jumped at the relay pump not working, then i probe the wires gets power from the ecm, but when i check to if the pump prime was getting power, the light just stayed on. so im thinking it maybe a short in the wire. then the next day when i go to try to start i used a jump starts sprayed some start fluid down the tb and low behold it started!!
now let it run for about 10min or so then i shut it off. i turn the key to the on position, now i hear the pump prime and getting fuel. now it only does this if i jump the battery and add starting fluid.
now here are my questions
could it still be my fuel pump?
if not could it be my battery?
would the fuel filter have any to do with this condition?
now one other thing to note, i notice that when it doent start, its raining like yesterday and the day it first stalled out, when its dry in can start it up like today.
also i do have a exhaust leak after the cat. so it does throw some codes. but one in particular is the code for system too lean bank 2 and code 420. this happened before the sub stalled out. could it have some do with this? any help would be great appriciated!!
