Working on a friends 95 ex and there is no spark or injector pulse. everything is plugged in. any ideas? cam sensor maybe?

 

are spark plugs good? ignition coil good?

 

is the timing belt in tact, cam turning over with the crank?

 

main relay? ecu fuse (fie/m) engine bay, the one you pull to reset the ecu...

 

if the timing belt is in tact , id say definitely the dizzy.

 

timing belt is intact, coil is good, cant get a code. got a new dizzy same ****.

Checked spark, checked pulse, inspected timing belt. checked coil, checked relays and fusable links, bought new dizzy(will return), don't have the conector to check codes on a honda so i tried to bridge and no flashy. checked to make sure everythings connected. car was dead when brought in.

 

If all that is good then I'd start to wonder about the ecu...

 

ecu...or fuse for ecu??

 

is the fuel pump priming? does the CEL come and then go out at Pos. 2? Im thinking either bad ECU or Main Relay

 

I am having the same problem

NEW distributor
ECU confirmed to work in friend's car just fine
NEW starter
NEW plugs

Able to datalog info from the ECU so I know it can see the motor. Also, checked for continuity on several lines and found no problems

NO injector pulse, just a drop in battery voltage.

Screenshots, wiring, and oscilloscope readings in this thread

check your grounds and check the ground on the thermostat housing make sure its not loose or rusted

 

Thanks for the reply

I have 4ga wire grounding the cylinder head and transmission to bare metal on the chassis. New hardware was used, and copper lugs were soldered on without using flux.

My thermostat ground was cleaned off with a file and a new bolt was used there also.

The pump primes and there is pressure in the rail
