As always check all fuses FIRST (electrics issues, EFI is that.)

the Puter magic is mindboggling, but..
why not post the symptoms, ????????
is it dead fuel pump or the more accurate, low or no fuel pressure?

All ECU/PCM (EFI ) all cut the pump for many reasons.
PCM is PGM-FI , in honda speak. PCM is modern term.
first really is fuse checks. !!!
1: no spark. (did you pull the CEL DTC blink codes to see if the ECU
is unhappy?
2: many cars (you must crank to run the pump) so looking not cranking for 12v at the pump , you fail and is normal.
(2 man rule one to crank, one to listen or check voltage at pump
or pump pressure at rail or filter) (a new filter is a good ploy now)

the fsm is here, and covers this, read the FSM
some pages are missing,,, so get real FSM

I like the (above) is cam dead?, line.... funny that.
(gather evidence, fuses good, cam spins (watch it) no DTC stored.
then check for spark no spark work spark now ,not fuel.
with a dead cam there is no CMP , no CMP the ECU pukes
codes for CMP Dead.
this is an interference engine so i'd bet that belt is fresh, huh?
ever 60k? per the opr; guide.

watch for codes, 4,8,9,15,16 (OBD2 DTC codes)
code 9 is dead cam. dead spark and all fuel is cut. for ever.
TDC&crank sensor, must work and not show DTC codes.

DTC flashing? The DLC jumper:
On 1990-95 Accord (except V-6) and 1992-95 Prelude, the codes are read from the check engine light after the two-wire service connector has been jumpered. On Accords, the service connector is under the dash on the passenger side. On Preludes, it is located behind the center console. Codes 1 through 9 are indicated by a series of short flashes; two-digit codes use a long flash for the first digit followed by the appropriate number of short flashes. For example, Code 14 would be indicated by 1 long flash followed by 4 short flashes. Codes are separated by a pause between displays. Multiple codes are transmitted in an alternating pattern. For example, a code 3 and 14 would be displayed as 3 short flashes (for Code 3) followed by the separator pause, then 1 long flash and 4 short flashes (for Code 14).

if fee for you , this very old car, so here is your long lost oper guide

1998. Ran out of gas. Now, why won't it start?


Running out of gas is hard on electric fuel pumps because they rely on the fuel for cooling and lubrication. But assuming the pump is ok, try opening a fuel line in the engine, to bleed the air out, when key is turned on and off a few times.

No exceleration now truck wont start


Fuel pump relay, turning the ignition on runs the fuel pump for about two seconds to pressure the fuel rail to start, then the fuel pump relay takes over once engine is started, it relies on a signal from the ignition or ECU (to say keep running). Either the relay has gone down or the relay has lost the signal. Don't bypass the relay, it's a safety feature, to stop the fuel pump if a fuel line ruptures.

How do i remove the fuel filter to replace it


These are your options James: Under vehicle, center, below seating area, mounted on top of fuel tank, in fuel pump module.That will be the component location.
Step1
Release the pressure form the system. This step is very important in order to avoid a personal injury or something else.
Disconnect the fuel pump fuse or rely. Then turn the engine on, just enough to consume what is in the fuel line. Once the engine start stilling shut it off immediately. Keep some shop rag when yuo unplug the fuel lines, some back pressure could remain there.
Step2
For your vehicle it seems the filter comes integrated in to the fuel pump. You have to remove the fuel pump.

It ran out of gas and now wont start. I put gas directly into throttle body, and it starts/runs, but wont remain started when gas runs out.


Sounds like fuel pump. Your fuel pump relies on fuel to act as coolant. Running it low often makes pump run hot and shortens it's life. Sounds like running out of fuel did just that. Way to test, pull fuel line off in engine compartment and have someone turn key to "ON" (NOT START!!!) position, you should fuel spraying out of line) If not, fuel pump is bad.
