Me and my friends have this 1991 CRX HF as a project car. Swapped a 92 B18 LS Integra motor in it. All wires hooked up. Checked everything. The starter doesnt work on battery alone. Jump it with my truck straight to the starter and it will kick but no spark! Distributor was replaced 20000 miles ago. Replaced cap on it (no spark), checked coil (20 Volts), swapped rotor (no spark), swapped main relay (no spark), check Throttle Positioning Sensor (no voltage). Soo, suspect ECU or wiring may be bad. What else should I check? Why no spark!?

 

Disconected the battery and then reconnected it crank it over for 30 sec and shut it off turn it on and look at your computor. Count the code that it might be given and count the lights more then once at a time cause it will give more then one code if u have more then one thing wrong keep counting until u conut example 6 light stops for a sec then it does 6 again well only code six is bad but if it goes 6 8 10 13 then all of those are bad just an example

 

Did you check fuel pressure? Loosen the main line to fuel rail and crank. Lets determine if its an ECU problem or ignition problem. ECU fuse in under hood fuse box good? Ground at the thermostat housing good?All grounds on and tight? Check and hit me back

 

He didnt mention the solid cel. Jumped the blue 2 pin plug and still a solid cel.

 

are all grounds hookrd up properly. Make sure you have metal to metal contact

 

We are checking out the main fuse box in the engine bay. Which wires connect to the two screw ports on the left? Right now we have 1 wire spliced into two coming from the battery. Should the wire go from the battery, to the starter, then from the starter to the fuse box? Which colored wires go in the other port next to it? Help!

 

replace the distributor. i had the same problem and i got my spark back

 

use this to test the distrubutor.
