Yes, this is indicative of fuel pump failure. It will need to be replaced.

if the low pressure is between 2 adjacent cylinders, it will be cheaper to replace the head gasket

Your transmission has a failed clutch pack most likely. Sorry.

Under driver side dash , above fuse panel

Did you check cylinder compression?

battery

Might be your fuel pump itself.

Your shifter cables are most likely worn out or stretched out. Adjusting the cables moves the shifter arm a little bit. The turnbuckles for adjusting are inside the center console under the shifter arm. To get to them, you have to take out the center console. One cable controls side to side movement and the other controls front to back, don't adjust the wrong one on accident.

Print the parts of a wiring diagram you need, at a repair shop, off their data base Too old for the trouble trees, unless you find OE Factory Manuals on E-Bay or somewhere

Replace them, usually with the control arm. This way it will get new bushings, too, which are probably worn.

the computer controls it bot it could be the crankcase position censer ect. have someone hook a computer to read codes on it

Honda engines are interference engines which means that valve damage will occur if the belt has broken or the correct procedure is not followed during belt replacement.

My honda prelude 1989 runs speed and later it will be slow and cannot run again.

may need to swap the computer also.. manual computer is different..but yes.. be looking into any vacuum leaks..block off any open ports you find..

you will need a new alternator. battery light means there is no charge in the electrical system. always first check the earths and wires before changing the alternator as a faulty earth can also be the main problem.

The clutch master cylinder must have gone out, the seals in it have failed. The clutch master cylinder (next to the brake master cylinder) gives you hydraulic pressure so the clutch pedal can operate the clutch.You can buy a new clutch master, a rebuilt unit, or yours can be rebuilt with new seals. Save time and money and buy a rebuilt or remanufactured unit. Once installed, you bleed the system down at the clutch slave cylinder, mounted on the transaxle.
