I didn't get a chance to search yet but i wanted to post this before heading to work. A friend of mine has a DA integra with the standard LS motor. The other day it stalled out on him and wouldn't start back up. his friend told him it was the distributor, so he bought a replacement and I installed it. Car worked fine for two days and then it started again. It will not start. Car has spark, fuel and pretty good compression. Timing is spot on. It cranks fine but doesn't turn over. Anyone have any ideas why its not working?

 

back probe the CKP (crank position sensor) to see if it is working properly and within specs. There is a good chance you have a bad CKP

 

Main relay is the primary culprit

 

If the main relay was bad it wouldn't crank

 

dont mean to sound dumb but how do i back probe the sensor? BTW just found out the car has over 400000 miles on the body and probably most of the sensors. this is the second motor the car has had. probably around 125k on this motor

 

the car is a DA there is no ckp

 

not true - when mine went bad it would crank but just wouldn't start

 

how can i check if it is damaged? the main relay

 

thanks for all the help guys, Ok, so i resoldered the connections on the main relay, none of them looked bad actually, but i still did it. Did not help at all. But something told me to take a look at the distributor again since that was the original problem. as soon as i took off the cap, i realized that the sealing ring was not on the distributor. Quickly i looked at the rotor, and low and behold, condensation was on it. I cleaned the condensation off and inspected everything and cleaned it. Boom, fired right up. we bought a new cap and rotor since the old ones were a bit used and i replaced the gasket. Now the car works perfect for now at least.
