2001 Honda Civic LX 4 Cyl 1.70L
01 Honda civic hard starting
01 Honda civic lx 5spd 192k hard starting, when cold requires cranking for 30 secs. To 1 min. to start. After initial start will start easily for about 3 hrs then will be hard to start again. New timing belt, plugs,coils, cleaned injectors, replaced evap purge valves, cleaned throttle body and intake control valve compression great, leak down test good, computer not throwing codes, no lights. Any ideas?
First question - what is the fuel pressure measured? At the fuel pump and at the fel injectors / fuel rail?
