i did a mpfi swap about a month ago and i had a IAT (intake air temp) code that i never fixed and everything else was running perfect then my distributer started making a high pitch noise. I drove it like that for 3 days and the day i was going to replace it, the car died out completly. I replaced the distributer but it still wouldnt start. Then found out car had no ground to the injectors. Went through the wiring it was all right, then re-did connections and re-did the pins on the harness where it plugs into the ecu, still no ground. So i replaced the resistor box, still no ground, then we found out there was no spark. i dont know what else to do


ive looked over all the wiring its all correct, i bought a new distributer, re did connections, tried another resister box, and tried another ecu

i still have no spark and no grounds, anyone want to take a shot?

 

anyone

 

CKP, crank sensor. Without crank signal the ECU can't send signal for fuel injection or spark (with an electronic ignition unit). Test the crank sensor circuit, see if it's getting power and ground if it is you may be having a problem with the mechanical side of the sensor. This means getting to the magnetic tooth on the crank position indicator thingy. This is at least the first place I would look.

Keep me posted

check the crank sensor the way u do this is just unplug the connector going to it and hook up a multimeter to it on the ac voltage setting and have someone crank it over if u are getting a ac voltage reading your crank sensor is fine also take a test light with 2 paper clips and make them straight and stick them into the connectors for the injectors and hook your test light up and crank it over test light should light on and off meaning the you have voltage to the injectors also do you have an external coil you can test that with a multi meter in the ohms setting when u hook it up u should get .6 to .8 ohms in the primary side and like 6000 to 30000 ohms on the secondary side try all this if it still wont start let me know im a honda technician at a honda dealership ill help as much as i can just send me an email hondacivic0909@yahoo.com

 

well we already tested the injectors and there not getting power because i cranked the car over and my friend held a test light to it and one side stays lite but the other side is suppose to blink and it doesnt
