92 GMC Sonoma 4.3 tbi
Ok guys, some may remember a few months back me doing several things to get it to run right, ended up being a fairly new fuel pump had gone bad. Here I am several months later and it acted up again. Changed out the fuel pump and filter. I cleaned out the throttle body and put a new gasket kit on the TBI. When trying to start it, it will turn over a few times then lock up like it's wanting to backfire, then start turning over again. After 15 seconds on the starter it will slowly start firing up and then run. I can run it up and down the street, but if it is put under too much load it will stumble like it's not getting enough fuel. The new symptom is the backfiring and stopping the cranking while trying to start. Any ideas? I put new plugs and wires on it thinking that I wasn't getting enough spark. It has a new coil, and ign module, no cat, clean egr, new temp sensor, and a few things I'm probably forgetting. Truck has just over 70,000 miles on it.
TIA
