Injectors stuck open

bloke · Post by **bloke** » Wed Feb 07, 2007 7:47 am

Please help someone my injectors have suddenly decided to stick open as soon as i power up. the fuel pump starts and the injectors dump the fuel straight into the inlet and cylinders.

We have checked all the wiring loom for direct shorts to ground and found nothing obvious but it only happens when the megasquirts plugged in.

im using a ms1 v2.2 green board msq .s19 files with MS squirt n spark extra on EDIS 6

the car ran fine for a while untill we changed the firing order on the injectors then it started and died out after about 10 sec of running

we have got 3 injectors per circuit

Ford Escort fitted with st24 v6 engine stock injectors

If you could post a data log, I could check if this is something Megasquirt is commanding this to do. If not, check for a flyback failure.

im new to this so excuse me if i seem a little stupid im not using a flyback board, we disconnected the injectors and put a test light in line and found they are stuck open as i said but when i turn the engine over they pulse as normal

i will try to get a datalog for you
thanks for your time as ive just about hit a wall on this, electronics arent my strong point
