Air filter box is already modified and snorkel removed.
No smoke at all except on startup... so a lean situation is indicated.
Hooked up my cheapie plastic fuel pressure gauge... not very reliable... but indicating only 3psi at idle (5psi engine off but pump running). I can get it to zero out...
Thanks for the feedback!
bad lift pump (did a quick test, seems fine, new one on hand to install but haven't)
ops (gauge works fine, LP seems to; have not tested further but for $30 I'll replace)
miles on injectors (unknown. newly rebuilt set on hand but not yet installed)
exhaust for leaks...
So I've had this 1995 2500 since spring. About 200k on it.
Fairly stock engine when I bought it... relocated pmt, later injection pump, had a turbomaster and gauges installed, guy was only running about 5psi and a stock chip.
I added a 4" exhaust and larger crossover and tweaked the boost...
