FlowForce Injectors not firing
First of all I have a 1989 NA. The Car has been stilling in storage since October. Over the winter I installed FM happy meal clutch kit, along with ff640 Flowforce Injectors. I also replaced all vacuum hoses and coolant lines. I recently got it put all back together, The problem I am having is when I go to crank it over the engine turns over but it does not want to catch at all. I looked to make sure i was getting spark to all 4 cylinder what I was. But after looking at the plugs more they were dry. The fuel pump does come on while I crack the engine. Next I go and check to make sure I have fuel pressure in the lines what there was. So i am 100% getting fuel to the rail. Made sure all my injectors where plugged in correct. I check all rounds on the car. The all have good contact points. So I believe I am just down to there being something wrong with my injectors or my tune. I really don't believe that it is something physically wrong with my injectors. I am running mspnp2 I believe I have I have my dead timings set correct to the the flowforce instruction on there website along with my battery voltage connection. I also think my required fuel is correct what is at 4.2. I am getting kinda stumped here. I am looking for any ideas of things i might have done wrong or whatever. All of this is fairly new to me.
(since this)^ I have changed the amount of fuel in my tune in the idle cells what didn't change anything Next I went and pulled the fuel rail with all my injectors still installed and cranked the engine over. non of the fuel injectors where firing. Wondering how I can check the wiring to make sure they are getting power. And or other things I may be missing or over looking. That would cause my injectors to not fire. |

You can literally fire the injectors using your ms test mode.

Any reason for the 2nd thread with the same exact issue? Test the injectors using the test mode in tuner studio. If nothing fires, then you know you have a power/signal issue at the injectors. Check for 12v at the injector harness. If you have 12v, test for continuity between the injector wiring and the ecu connector. You can make a ghetto noid light with 2 wires and a single led light as well.

Voltage passes thru the INJ fuse and then main relay, so key should be in the on position for + current. ECU provides the ground for the injector.

I don't have a mega squirt (or tunerstudio) so I can't explicitly tell you how to enable test mode, but does this link help https://bartuneengineering.wordpress...ecu-test-mode/?
