ok so i just swapped an obd0 b18a into my crx si. now im getting a no crank no start. I have full power....i turn the key on....then to start....nothing happens but i can hear the whine of energy draining from the battery....then when i turn the key back i get a click noise from the driver side. Can someone help me here.

 

well start with the no crank. Why isn't the starter turning over?? incorrect wiring maybe.

 

grounds?

 

Breaker bar on crank pulley to make sure engine is not seized?

 

check fuses check for correct wwiring like said above. check the two wires that run into the fuse block under the hood. one goes to the starter and one goes to the battery i think, make sure you dont have them backwards, although im not sure if it matters or not

 

Ok so i forgot the grounds....i put a ground from the clutch cable bracket to the chassis then one from the valve cover on driver side to the radiator support. I thought there was 3 grounds on B series motors but idk where the third one goes....With just 2 grounds...same thing. no crank.....

update* that 1 loud click noise is the starter.

i turned engine by hand...moves freely.

gonna remove starter and bench test it tonight....

any more thoughts?

 

thermostat ground

 

thank you...where should the ground go to...?

 

to your thermostat housing

 

i meant from thermostat housing to where...but i found a ground on the engine wiring harness that i believe is the thermostat ground. will try that tonight.

starter tested good....failed for chatter time but still spins.

hoping its this ground...

 

still nothin, starter is good and all grounds are there. any ideas?

 

when you try to start it do the lights dim on the dash?

 

no sir, they stay bright. Gonna try a new battery cuz i swear my grounds are all good...the battery is free under warrenty anyways so ima give it a shot. if not im gonna pull the starter back out and sand down the mounting spot on the bell housing for a better ground contact maybe? and replace all my grounds and sand all the areas to ensure perfect contact. ill update tomarrow!

 

Ok so my interesting no crank turned out to be a defective battery.... F**K pepboys battery testers it said mine was good lol. but yah new battery and it cranks....no ecu plugged in because im trying to prime my oil pump.

now new problem...i cranked for about 10 second intervals about 4 times and saw no oil pressure....ive heard 30 seconds of cranking to prime the pump. do i have to crank continuously? because it seems like the battery will die before then. i didnt even get any oil flowing through my pressure guage line.

 

do you have a mechanical gauge or an electric? if you have a mechanical one the oil has to flow through the long line into the car so it might take a few seconds to see anything. and also make sure the battery completely charged or else it will crank too slow and the light or your oil pressure gauge wont read and the light will stay on
