sr20 cranks but doesnt fire up

[RPSilvia]

i swapped a sr in like a month ago and was running fine till today. i went over to a friends house and when i was leaving it just wont start.i already checked the fuses and they are good. ecu throws code 55 which if i remember correctly is a malfunction but i dont know what.tomorrow i will check the wire harness, fuel, compression and timing. anyone have any ideas? also how do you check if the coil packs are still good?

thanks

Code 55 is Other Malfunction. CONSULT Terminal Required. Now their was a swap I did that done that and their was two things wronge the CAS plug was not fully in and when it backed off it blew the fuse to the fuel pump. Even looking at the fuse it was good but checked it with a multi meter and it was blown.

Uh iirc Code 55 means its fine. Are your cylinders flooded?

That happend to me before and i did not know what it was for two days then i started to check power though all the wire and found on the starter the one small plug to engage it fell off and i pluged it back in and it fired right up, i felt dumm after that cuaes i didn't know what it was than found it and thats all it was.

True that, always Ohm out fuses because they don't always appear blown
