No Injector Pulse issue

[82te72]

onto the next issue. once i get this figured out ill keep installing. I just want to make sure i have all signals i need to run before i put more time into it.

The problem is that i have no injector pulse.

here's what i have going on. Im running an ms1 with firmware 029y4. I have edis working and a pip and a saw signal. So thats good to go. However when i connect up a noid light to the injector plugs they do not flash.

for the injection system: im using 28zx injectors (low I). i have a 6 ohm 25W resistor in series with each injector. I set pwm% to 100 and pwm time to 25.4.

I set the LED 17 (d14) to squirt

when I crank the car led 17 flashes, however noid light does not flash. the noid light is good so thats not the problem. I have checked every injector plug as well, same problem persists.

my msq file is attached hopefully someone has an idea. Im sure its something simple im just not getting.

do you have a voltage between one of your injector plug pins and ground?
You would need to test that while cranking if you are wired up as per http://www.msextra.com/doc/general/ms1external.html

yeah i have 12v between one of the pins and ground. and i wired it up just like that diagram, only bypassed one relay temporarily until i get all signals.

Did you build your own board? DIY has a cool page on testing the driver circuits. http://www.diyautotune.com/tech_article ... ooting.htm
You could take a log of cranking and post that up but to me, from the led behavior, the MS thinks it's squirting.

[82te72]

well i just redid some tests. and it is "squirting".

so i guess my initial accusation was incorrect.

when i connected up a noid light straight to battery and then the other side of the noid light to the injector grounding system, the light did become visible after about 5 cranks.

however when connected up to both sides of the injector plug, still no light.

could this be due to the resistors i have in series on the power side of the injector wiring?

[slow_hemi6]

Yeah sounds like it's just the resistors.

ok ill get the rest of the fuel system plumbed and wired and see if the injectors really do fire.

thanks for the info.
