My loss of acceleration power has led me to this result. truck is popping no codes, the crankshaft sensor i just replaced, fuel pressure checked out good, cats checked out good. anyone have any suggestions for a good fuel pump and approx cost??? also how difficult is it to do this, time frame? thanks, matt

 

Not sure if its relavant. Had a 90 blazer throttle body. Idled and ran great until I got on it heavy and it almost stalled. It turned out to be a dirt fuel filter. try that first.
