1993 accord no strart
I have a 93 accord I bought with a wrecking yard motor installed that wasnt completed. I installed new timing belt,water pump etc. I tried to fire up but will not start. I installed a new distributor, coil, plugs and wires. Previous owner installed a new fuel pump and verified if has good fuel pressure., I get good spark but still will not start. I double checked timing and all is good. I pulled plugs out after cranking and they are dry. no sign of fuel getting to them. Any help would greatly be appreciated

Last thing in the fuel chain is whether the injectors are firing.
Each injector has a 2-wire plug. One wire on each is all the same color - that wire should have (+) battery voltage all the time whenever the key is ON. Check for that. If you don't have it, look for connections, fuses, etc.
The ECM switches the ground on & off for each injector. So each of the 4 injectors has it's own wire back to the ECM. Check that if the (+) side of the injector circuits are OK.

Hi Jim, I checked and only the #1 injector has 12 volts. None on the other 3. I tested the yellow wire on the main relay and that has power ( yellow wire) Do you have a wiring diagram you can share with me?
Thanks

They main relay supplies power to all the injectors through the injector resistor. The engine computer grounds the injector to open the injector.
The injector resisitor is a box with metal fins near the top of the engine bay near the driver's side of the windshield. There is a connector nearby that is identical and can easily be switched. The wires going to the injector resistor connector are something like 1 red and 4 red/blk.

The main relay switches the hot lead for all injectors. The ECU provides a ground pulse when it wants to fire a particular injector.
I don't have a circuit drawing for 1997, but there should be links to shop manuals in a sticky thread up top somewhere.
