no i didn't use the stimulator, this problem has to be with in the wiring itself because not only am i getting the voltage reading out of megatune, but also at the connection to the fuse block and gronded to the battery.

This is getting slightly off topic, but here it goes. I bought a preassembled Megasquirt unit and tested it on my desktop computer. I used a power adapter from a cordless telephone to provide power. Have you ever had this unit powered on?

yeah its getting power in the car, i'm getting readings and everything from all the sensors. but when i try to burn the chip it says not enough voltage to burn safetly. which is where this problem comes in play. because with out burning the chip, the injectors aren't getting enought fuel to start the car.

I figured out the problem with the 4.5v and such but now i ave another problem
here is a picture i made of my wiring,



they only thing wrong with it is that pin 85 on the FP does lead to pin 37 on the Db-37 connector. I didn't see it go there before but i just went out and doubled checked it and it is going to the right place.

Now i have 12v to ms all the time even off, but also the FP turns on only turns on for a second or 2 after the car is turned onto ACC.(according to MS's LED's). The FP is not turning on during cranking, again noticed this by MS LED's that turn on when the FP is turned on.

Also the Injectors are not firing, according to the LEDS once again

but i did get the car to fire, and then die instantly

I know nothing about MS... But I am familiar with Hondas. If i understand you right your using the fuel pump circuit to power up your MS ECU? Have you considered that the fuel pump always cycles on at key on, to bring up the fuel pres.
If i remember my info correctly the fuel pump run signal after initial start cycle then comes from the ignition circuit (Dist).
What year and model is this caar??
