hi folks,I’ve had this v6 94 TBI K1500 for a couple years.
Few issues, but the engine was running good all summer.
I replaced coil, wires, spark plugs when I purchased it.
I noticed a bit of occasional hesitation when accelerating, particularly from starting off, but didn’t think much about it.
A few weeks ago she had trouble starting, I checked the injectors and spark at each plug, all good.
I replaced the ignition control module.
An extra ground had been temporarily added to the fuel pump for some reason (previous owner) and I cleaned that up.
The truck started up and was working fairly well (still a little hesitation at times).
I used the truck for a few days without issue around town.
Yesterday I decided to check the timing, and left the truck idling for a few minutes to warm up.
The engine would idle normally, then bog down and put out tons of black smoke, then Settle down and idle normally again.
This cycle would happen every couple minutes. I didn’t check the timing at that point and shut down the truck.
Today I was going to move the truck into the garage and replace the fuel pump, just in case. Unfortunately the truck tried, got close, but would not start.
Spray from the injectors looks good, spark is there but it will not start.
Hopefully someone has some suggestions, not sure where to start.
Thanks
Stewart
