help: No ground pulse to injectors
 
fd engine having starting problems.

details: so its a new engine from a 95 fd, but its not getting any ground pulse to injectors.

it has fuel pressure

spark plug cables have spark

relays checked and jumped

injectors have spark

all fuses have been replaced


any ideas on how to correct the problem?

also its using a cali ecu from an fd with built date of 02/02 could the ecu be the prob?


we will be trying a PFC in the morning.


anyone have had similar problems...searched but came out empty

Fixed problem:

turns out the injectors were gumed and the stock ground wasnt enough to release them. so we jumped the ecu grounding points and heard the injectors click.
fired her up and bam smoke everywhere....good ole rotary =)
