Question about 1999 Chevrolet Tahoe
I replaced DA fuel pump
And I hope you replaced the filter too, :)
Off hand I would ask if any trouble codes popped up like multi-Misfire
or engine code's of P0300- P0308, "no spake at plugs or a misfire at plugs.?" You might need a ignition control modular, "MIGHT" for some reason there's usually not a code for the ICM but you would get misfires since you lose spark to the plugs..
if your ignition control modular is inside the distributor cap and you decide to have it checked auto part stores can check it out of the truck, BUT I would add a new on IF your getting codes of P0300-308 since they run hot, and if you do replace it get the heat sink grease for the bottom of it to help keep it cool, They get Really hot..
Just my thought.
