ok hears the deal. i got a 90 crx from this guy with a obdo ls swap in it. ghetto wired up. they didnt repin the ecu and left the crank angle sensor unpluged they rewired the injectors and the car ran but would not go over 3k rpms due to no crankangle sensor. so i cleaned up the wiring and rewired the crank angle sensor at b10 and b12. and now the car will not start just turns over. fuel pump is now not priming tried 4 different main relays and a couple of them known working. i can jump the fuel pump and it turns on. grounds on the motor and thermo housing is good. the only thing not hooked up is the iat and i couldnt find the wires to that and the plug is no existant. so i go a plug no i just need to know what pins on the ecu also go to that piece so i can just hard wire it into the ecu. but my main concern is the car not starting. tried other dizzys from other car and still no start.

day 2 replaced the dizzy with a brand spankin new one and it starts but dies a few seconds later and fuel pump kicks on now. but i noticed the tps connector on the tps itself is broken. so i have ordered a blox tps and will be replacing that. hopefully that is it.

day 3 replaced the tps with the blox voltage is good and in spec. but still no start. i pulled each plug wire 1 by 1 and the spark seems weak. the car will try and start then fire up and then die. then turn over like its flooded. im mind boggled.

 

anyone

 

Check the ground on the thermostat neck. I had the same problem and that loose connection was the culprit. Are you getting any cell codes? Also make sure the color code on the engine harness part of the distributor plugs is correct with the distributor. A lot people mix up the two white wires

 

everything is good. this is to wierd i have checked everything over and over. and all it does is start and shut down.

 

swap the 2 white wires on the dizzy to the harness

 

i already fixed the problem. replaced the whole harness

 

So the harness was the problem?

 

sure did
