Print the parts of a wiring diagram you need,

Too old for the trouble trees, unless you find
OE Factory Manuals on E-Bay or somewhere

best bet is go to honda tech.com

If the miles turn fine and the speed arm doesnt move you have a problem with the tachometer this is refeered to as RPM,This get is signal directly at the ignition negaive part if the coil, If the connection at the coil is in good order a RPM gauge or Tachometer will be your solution

Check Fuel pressure with gauge to see pressure is not out more that 5 psi variance of spec. If initial pressure is good, Start with Vulture pump and then on to the ground on the sending unit in the tank attached to the fuel pump assembly. Easy access through the trunk. Ground wire insulation should not be brittle an cracked.Replace wire with 14 stranded THHN or wire from spare harnessing. Wire should be pliable and have good mechanical connection on the spade connector. Ensure clean connection as corrosion of dissimilar metals will invite corrosion over time.

hope this is what you were looking for. let me know if you need more!

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.

You can download the entire manual from www.pdftown.com
Here is the link to the shop manual for the 88 prelude that I used to do my Cam Belt.
