the 13th round

had a quick question about the main relay.
how do you know if its bad?
when i put my ignition key in and turn it to the second click, the relay clicks rapidly and when i try to start it picks up pace(clicks faster).
would this be the reason my car wont turn over?

battery is dead

the 13th round

no, car turns over and i had jumpers on it anyways, just wont start, turns and turns no ignition.
also the ecu flashes in time with the relay.
and this is on a mpfi swapped car.

go back threw the mpfi swap. in extreem detail loose wire. dissconnected wire. anything look closely. sound like cylemder sensor. what ecu and you useing



then come back. usually when relays are bad they dont cluck at all.

There's a ton of people who mpfi swap..and don't connect the grounds. Then they say, what the ----? At least you got it figured out.

if it clicks the power source is creating a magnetic field inside the relay causing the armature to close a circuit. It then in turn is working.
