I have power to all 4 injectors but no ground signal pulse to fire them. Spray staring fluid in intake manifold and it starts right up.

Was wondering if I could somehow take a log of my car cranking over and post it on here and if someone could look at it and see if there is something missing or not working that they see.

Removed at ecu:

#6 EGR solenoid relay ground (control)
#16 Evaporative purge solenoid relay ground (control)
#26 Rear O2 heater control
#35 Evaporative ventilation solenoid relay ground (control)
#48 Fuel pressure solenoid ground (control)
#65 A/C control
#72 not used, causes ADC 08 to flip from 0 to 1 when 1.7 V applied
#83 A/C control

Thanks feautoevo but I would rather not trailer the car around if I don't have to.

Fast Freddie: I have not disabled the immobilizer yet but I will try that.

Here is what I got today.

All sensors are grounded through the ecu just fine.

#1 Injector #1 12v and signal wire has continuity
#2 Injector #4 12v and signal wire has continuity
#3 Front O2 heater control 12v and signal wire has continuity (2.6v and .2v others)
#9 Injector # 2 12v and signal wire has continuity
#11 Ignition coil cyl #1 and #4 12v and signal wire has continuity
#12 Ignition coil cyl #2 and #3 12v and signal wire has continuity
#14 Idle air control 12v and signal wire has continuity
#15 Idle air control 12v and signal wire has continuity
#24 Injector #3 12v and signal wire has continuity
#28 Idle air control 12v and signal wire has continuity
#29 Idle air control 12v and signal wire has continuity
#32 Mivec valve control 12v and signal wire has continuity
#34 Sensor ground good
#41 Waste gate solenoid relay ground (control) 12.1v and signal wire has continuity (11.4 other)
#42 TPS power 5v
#43 Crankshaft position sensor signal 12.1v and signal wire has continuity
#44 Coolant sensor signal 4.7v and signal wire has continuity
#46 Ground to chassis is good
#47 12V Power (via MFI relay, likely follows IG1) 12v power when key on
#50 Exhaust cam position sensor signal 12.2v and signal wire has continuity
#53 Intake cam position sensor signal 12.1v and signal wire has continuity
#58 Ground to chassis good
#59 12v Power (via MFI relay, likely follows IG1) 12v power when key on
#60 Power from battery (always live) good
#62 IAT sensor signal 4.6v and signal wire has continuity
#71 Front O2 sensor signal 12.1v and signal wire has continuity (2.6v .2v other wires)
#78 TPS signal 5v and signal wire has continuity
#80 Vehicle speed sensor signal wire has continuity
#91 Knock sensor signal wire has continuity
#92 MAP sensor signal 5v and signal wire has continuity

#44 and #62 are the only ones that seem a little funny but not enough to make car not start.

I am tuning dumb. Any help would be appreciated. Thank you.

when this happened to me, it was my ecu.. the transistor that triggers them was toast inside the ecu, I swapped ecu's transferred my immob code and everything was perfect again.

 

Just noticed you are in WI, too I'm just west of you in Sparta, my issue was on my evo 8 though... I was thinking, if you have evo scan you could see if your CAS somehow isn't responding.

 

I have been doing a lot of weight reduction to my car.

I took out all the a/c wiring, egr solenoid, evap solenoid and fpr solenoid wiring. Also all the air bag wiring. All taken out of the engine harness. The interior harness was done awhile back and everything was fine with that.

If anybody has any ideas to where my signal went, please speak up. Thank you.

 

My beast needs a diet! it seems amazingly time consuming to do all them wire pulls etc

 

Yes it sucks and now has caused this problem.

Anybody???

 

Help!!!!!!!!!!!

 

Honestly you will need to check at your ecu to see if the wires are triggering at the pins with a multimeter. You can also test the continuity of the wire from the ecu to the injector to make sure something didn't get snipped by accident. The other quick check is the crank angle sensor, but you need evoscan and a tactrix cable.

 

Yeah get a noid light, trigger each injector through evoscan, and put a resistor in/on the ecu wire. I know i found the ecu schematic online - you'll be ok.

 

Are you getting a crank and/or cam signal?

 

I had my wife upload a log. I do not know if this is right, it's in the first post.

Started data log for a second or two and then cranked car over for 5 seconds. Please let me know if this log was not uploaded right or something is wrong there. If you can see the log, please let me know if you see a missing signal anywhere or what I would need to do so you can see a missing signal.

Thank you.

 

Something is real screwy with all those readings. Battery voltage drops down to 1.02V, rpm, coolant temp and baro pressure readings all over the place.

 

I got nothing, don't even know what I am looking at there. If anyone could point me in the right direction, that would be great. Would rather not have to replace the engine harness.

 

Can you try the ecu in another car and do another log?
