Questionone way or another I will fix it... yes i have ample fuel pressure yes the new distributor has a new icm, and yes i already know wires crossed and created a short... i just have to find where... where is g401 and g402?

The mil is on steady the 4th pin on the top of the plug shows .02 ohms. even when i jumper the bypass plug above the ecm it stays on constant. the g 101 at the water outlet tests .02 ohms at the outlet and at the plug to the ecm. what about the green/red wire from the ecm to the resistor pack in the fuse box (the eld? or brown pack that has 3 wires to it) my book states that wire should show 5.+/- volts but it shows nothing? the other two wires there test fine according to my manual. what other wire is the power wire for the ecm? also i tested every wire on the side of the ignition key assembly for ground, without a battery hooked up certain wires show continuity to ground in different key positions but they have one thing in common when they do; they all read 7.3 ohms or so. you said to check the ground inside the distrib at the igniter do you mean on a certain wire or just the spot where the little tab screw to the distrib housing? at the housing it reads .03 ohm, no wire to the icm read ground except those connected to the coil (with key off). i know i must be missing something right in front of my nose. once again i appreciate the advice

Yes I am showing power at the coil through the black\yellow wire. At the water outlet the grounds looks 2 be in good shape what ohm should it meter at? I did find an issue at the plug for the crankshaft fluctuation sensor the wiring going to the vehicle(away from sensor) a white and red wire direct to ecm shows ground?, an blue orange wire not showing anything, and a brown/black wire supposedly ground is not showing ground but i traced direct to ecm and my haynes manual states it should be consistant with ground. where is the main ground for the ecm? it doesnt seem to use the mounting bolts to ground itself? but i have removed the blower motor housing and didnt see grounds... I believe its a burnt ground too, but its driving me nuts trying to find it.. thanks for help, really appreciate it.

I have a 1997 honda civic ex 2dr d16y8 and had an aftermarket distributor cap by msd. the cap allowed moisture to build inside the distributor and destroying the shielding on all the internal wiring. I believe a short occured with one of the sensors inside the distrib. now i am not getting any spark. the coil is getting power from the ignition switch. the wire in the distrib harness for the ignitor to ecm is not showing power. i have replaced the distrib and all wiring, the ecm, checked the main relay, the ignition switch and ALL fuses under hood and dash. I believe the ecm is not powering up for some reason, besides not getting power to the ignitor from ecm, when i hook up an obdII scan tool it is saying error check connections, of coarse the connections are good. the civic is an ex model and i know the factory theft unit runs through the radio, if equiped with the starter kill option and it was tripped the vehicle would not crank correct, or would it prevent spark? the vehicle is cranking fine just no juice. any ideas or suggestions would be greatly appreciated.
thanks

Hey Jon you got a good one here. First, you are correct the vehicle would not crank if the vehicle alarm equipped with starter kill was tripped. Check the condition of ground 101 at the thermostat housing below the ECT switch, it may be loose or a bad connection. At the igniter you should have batt v+ at the blk/yel w/ ign. on. The same goes for the blue wire(hitachi) or wht/blue(tec). Whats the mil light doing, does it come on at all? I think you do have either a pcm gnd/power issue. Let me know. RICK
Answer -
Don't check the power at the coil check it at the igniter inside the distributor. A good ground will show 0.0-.2 ohms from ground to ground. Check continuity from the PCM ground to either the G101 or just to chassis ground. If you're not reading what I told you previously you're going to have to trace the wire to an open or run a new wire. What about the MIL? RICK
Answer -
Just a quick little question, did you replace a complete distributor with the icm? I've seen where they cross 2 wires on the igniter and that'll create a no start. Are you sure you triple checked all your connections? Are you getting fuel? Without seeing the car diagnosing is very difficult, sorry Jon. You may have to swallow your pride and take it to the dealer and explain everything to them so they can diagnose it properly. RICK
AnswerG401 is in the drivers kick panel. If you follow the hood release cable its just above it right near the firewall. Be careful because theres G551 just below the cable on the left side of the harness. G402 is located behind the right side of the dash panel right by the heater motor. There's a 20-pin junction connector right beside the ground. Good luck, RICK
