Hey guys. Sorry for so many new threads asking for help, but this is getting a bit frustrating and I cannot find anyone else who has had this problem.

So last weekend I plugged the squirt into the car and tried to fire it. It did no such thing . Looking at tunerstudio, I could tell I was getting tach, and I could smell fuel, but when a buddy hooked a timing light up, It was evident there was no spark. Here is the catcher though. The ignition lights are flashing.

I built a jimstim and tested the board to find that I have solid tach. But when you look closely at the ignition lights (both on the squirt and stim) they are never off. There is a high and low voltage that they flash between, but unlike the injector lights that true flash on-off, the ignition lights are go from bright to not-so-bright. I have Joe Perez spark output on, with spark going high. I'm thinking about taking the transistors out and just doing standard output, seeing my proto area work is sloppy at best. Its actually pathetic hhaha. Thanks for your help everyone

*Thanks for your help anyone

Do you have 0 volts or 5 volts on the spark outputs with the key on and engine off?

DKdekes

Thanks for the reply! I'll check tonight

Hooked it up to the car again, I'm getting 5v with ignition switch on. TS is set for the spark to go high. I cranked the motor a lil and noticed that d14 and 16 are actually not flashing! They did flash very mildly when tested on the stim, like I described, so I thought I just hadn't noticed the flashing when the board was on the car. But yup, d14 and 16 are not flashing on the car... should have done output test mode!!! I didn't think to try it when I was at the car, and unfortunately it is at a friend's and I have somewhat limited access to it. But I'm thinking now it is not a MS related issue. Maybe coils not hooked up to battery...?

DKdekes

Maybe harness?? Attached (I hope) is the diagram I used. Perhaps I'm missing the ground for the coils through the ecu?

Edit: I kinda mixed and matched two diagrams...lawl the first diagram (90-93) I used to see what pins of the DB37 I needed to connect to. The second one I used to see what wires of the harness I needed to connect to.

You need to change the spark setting to going low if your outputs are at 5V with the key on and engine off.

DKdekes

FRICK! Ok thanks. I'll go try on the car tonight. But I still find it concerning that the led's don't flash when cranking on the car, but do flash when hooked up to the stim.

DKdekes

I apologize for the delay, but that did it! Timing light goes on now. Just need to get some gas in the car and charge the bat, and figure out some error codes on TS and I will be good (so long as I don't get stumped by another simple problem like this one). Thanks a lot Matt!
