Braineack, we didn't remove any fuse. I remember you mentioned NOT to remove that fuse a while back, so I didn't

The fuel pump was jumped though..

I'm wondering if maybe it's a TPS issue? if the MS is in flood clear mode, it won't send any fuel to the engine right? When i try to calibrate the TPS i always get '128' whether throttle is fully depressed or not at all.. Does this matter? is there a specific way to tell the MS to completely ignore the TPS readings?

there's no TPS. manually enter 0 an 255 into those banks.

i'm outside now.. i set the tps values to 0 and 255.
not sure if it matters, but the throttle % under realtime display is constantly ********. the calibration value went from 105 to 40 in a matter of 5 minutes.

also -- the 'launch on' box is always red at the bottom of the screen.. does that matter?

so any MS pros around the NY/NJ border? If not, i'm getting ready to give up on this thing, you can keep an eye out for a nice MS in the classifieds

anyone want to trade for an MSPNP maybe?

The MS only controls the ground. If when the MS is in place and you're not seeing a +12v reading, then you must be removing the INJ Fuse at the same time...

Did you guys jump the fuel pump to turn on in the diagnostics box? You shouldn't have removed ST_SIG, this isn't a MSPNP and it wasn't in my original instructions. If the ST_SIG fuse was pulled, it's possible the fuel pump wont turn on, even with F/P and GND jumped in your diagnostics box.
With car off and the factory computer in place the injectors get no power, soon as you crank, power is present.

This is not the case with the Megasquirt.

We removed no fuses and the fuel pump was jumped and is audible on key on.

To be totally honest, I think its your megasquirt. I verified your harness and its fine, but the injectors are not getting triggered. If you built the MS correctly it should be working.

Did you test it on your car prior to shipping it?

It'll be fixed and back in the mail tomorrow. It was obvious what was wrong as soon as I lifted the cover off.

got the MS back today. Plugged it in, started on the first try.

I got a couple of nice big pops, the 1st couple of times i turned on the ignition, i guess my priming pulses were a bit long?

anyway, the car started and was rough until i tweaked a couple of things, but now it idles somewhat decently.

I'm going to install my WBo2 and the IAT next!

I bet he forgot the injector circuit.

Fess up Scott, what did you mess up?
