Check diyautotune for pricing. Visit the megasquirt extra forum.

pretty sure i do. will check tomorrow.

Fixed. See CCCI testing/swapping thread. Sorry for the extra bandwidth.

Fixed. Some times the simple things are the answer. The coil pack was firing all along. The secondary wasn't sparking due to carbon fouled plugs. I cleaned the plugs early in the game by heating them with a propane torch and burning the carbon off, but enough was still on the insulating towers...

i have battery power at the module. did some testing from a troubleshooting flowchart. this advised to check power to the crank and cam sensors. spec is between 6 and 9 volts. i have 5V. at this point the flowchart suggests bad wire integrity or bad ign module. wiring ohmed out fine, and it's...

hi, i'm no expert but these cars cut out under load sometimes b/c of the coilpack. this problem usually only shows up under boost though. you can ohm out the coil to check. should be around 11-12k ohms.

this problem is starting to wear me out. ECM swap did no good. still no spark. I picked up a CCCI unit from an 87 lesabre with the same blocky coil pack, but found out the connector plug is different. does anyone have an interchange for ignition modules for the 86-87 cars? or can i use this...

I do not have 5v signal on the EST line from the ECM. pulled the ECM and checked the board under a magnifying glass. found some ceramic SMD resistors were cooked. so the search for another ECM starts.

ok, found the orange wire under hood. it was in pretty bad shape, corroded. repaired the bad section but the light still flickered. tried a different chip and the light is solid now. but car still won't start. timing light suggests still no spark. i see in wiring diagrams that there is an EST...

sorry for the new threads, i thought that might be best since i discovered new info. actually, the original problem, like you said, needs to be addressed.(flickering engine light) and i didn't mention that my ECM connectors gave me issues before. a couple years ago: i sprayed the harness...

86 ttype.. Been working on my no-start all day and discovered no spark. Checked the CCCI module harness- it's getting power, ground, crank and cam signals. Coils are good. I'm suspecting the CCCI. Anybody know how to test them? Anybody in the Tampa Bay area have a spare CCCI i can borrow to test?

check engine light flickers with key in "on" position and while cranking. light is constant dimly lit solid with a brighter flickering. (while key on and crank) oil pressure connector looks good but shouldn't be a factor during crank since there's no oil pressure anyway. pulley looks good. I...

I checked the ECM harness orange wire has 12V and the three grounds are good. No codes. Cranks but won't start. Will cough and sputter with starting fluid but won't run. Fuel pump is running. Cranking compression sounds good and timing chain was recently replaced. Car ran fine after chain...

ok thanks. for some reason i thought the 87 connector plugged strait to the green circuit board. i may of got this idea from looking at some NA cars in the junkyard.

Hi, Are the 86-87 ECM's identical? I thought the connector plugs were different. Anyway, I'm checking my 86 ECM harness for power and ground, but i only have an 87 shop manual. Are the pinouts the same for 86 and 87?

just what i was looking for. thanks so much!

only one i found is this: http://www.gnttype.org/techarea/ecmsensors/regal_ecm.jpg I can't make out the text for any of the pin outs. anybody know where i can find the same page but more legible?

thx for the replies guys and novad don't worry about being long winded, i appreciate the info.

questions: 1)where to buy a pigtail? available new or junkyard? 2)if the connector is bad, how do i know that the ECU pins aren't rotton too?

search worked, i got the link. looks like i got a project now...:rolleyes: thx so much for the help!
