ok so my cousin has a 90 integra 4dr Automatic. ~3 years ago we bought a 90 DA automatic RHD front clip with a b16. we swapped the motor in since his b18 was toasted.

just recently, his car starts to die out while driving sometimes. at one point, he called me to go help him push his car from a stop light cause it wouldnt start. his car sometimes doesnt start when he goes to work or when getting out of work. but most of the time it starts.

it has a new dizzy cap, rotor, spark plug wire, spark plugs, alternator, & battery.

all his car does is crank, but doesnt turn over. sometimes the starter doesnt even crank at all!!

we swapped battery into my car, works fine, we swapped his dizzy into my car, works fine. vis-versa, it starts his car also (probably just a time when his car did start)

another thing we did was swapped out the b16 ecu and ran his LS ecu to see if the ECU was the problem. (few cells but didnt effect anything) drove fine for a week or so and now just today his car has that starting problem all over..

i dont know what else to trouble shoot so im thinking main relay?? i turn to you guys for help and any help is appreciated. thanks

 

swap main relays for a week?

 

could that be the problem? well i needa get one then cause i need mines..and give that a shot

 

havent got a chance to get a relay, but will be getting one. also is there any chance that it can be the ignition module?
