yeah the pump primes. it was idling out side and i went to leave and it acted like it was running on 2 cyl. and wouldnt start after that. po6 ecu. checked timing, ecu, spark, resistor box, main relay, CEL was 41 no big deal alwasy threw it, no it dont stay steady it turns offHow did this happen? What ECU?
Does the fuel pump prime?
Does the CEL remain on steady when you turn the key from off to ON(II)? Or does it turn off after 2 seconds?
Are any CEL codes thrown?
ive used this ecu for the last year, i have 440 cc injectors DSM. i removed the rail and no fuel sprays out when trying to start. now if i remove the injector it s acts like its under pressure and shoots it out and gets fuel everywhere indicated the injectors have a MIL idk what tho....You are not running the right ECU for the engine. And why do you need a resistor box?
If you remove the fuel rail with the injectors and crank the engine, do they spray fuel?
I know it's somewhat a side issue for this thread, but shouldn't you be running a P75 ECU?ive used this ecu for the last year, i have 440 cc injectors DSM. i removed the rail and no fuel sprays out when trying to start. now if i remove the injector it s acts like its under pressure and shoots it out and gets fuel everywhere indicated the injectors have a MIL idk what tho....

Start here:
Remove ECU connector A and check whether terminals A23 and A24 have continuity to body ground.
List what else you have already done, so I don't waste time mentioning irrelevant items.i already checked this and its fine... i tried a new ecu as well and it was a p75...
BTW when i check for continuity. i used a test light and clipped one end to the body and inserted the other end in the A23 and A24. it lit up but did i do it wrong if so ill re check a few other things as well
okay i tried my timing, ecu, resistor box, main relay, actually changed my injectors and still nothing, made sure its getting fuel to the rail. it is, pump is good. no blown fuses, cleaned grounds,List what else you have already done, so I don't waste time mentioning irrelevant items.
And get a digital multimeter. They're not expensive.
Please be much more specific about what you tested. Are you referring to A23 and A24?okay so my grounds are all good i hooked the light to the pos side of the bat and checked and it lit it up.
yeah i tried them sorry. what i did today: new ecu again, new pump, ignition switch, injectors, engine harness, main relay again, fuel filter, i tried just about everything...it gets constant 12v to every injector but weird thing it...when i hook the test light to the pos side of bat and to the signal wire on the injector and try to start it the light blinks...does this not mean its getting a pulse meaning it should put out fuel?Please be much more specific about what you tested.

You are straying off track and doing tests that are not informative.yeah i tried them sorry. what i did today: new ecu again, new pump, ignition switch, injectors, engine harness, main relay again, fuel filter, i tried just about everything...it gets constant 12v to every injector but weird thing it...when i hook the test light to the pos side of bat and to the signal wire on the injector and try to start it the light blinks...does this not mean its getting a pulse meaning it should put out fuel?

What have you done with A23 and A24? i had a test light put one end to pos side of battery and other end in A24 and A23 What were the results? it lit up
Do you now have a digital multimeter?yes If not, you NEED ONE ASAP to diagnose the problem.
Do you still have bright white spark at all 4 spark plugs?yes
okay ill do this tomorrow and let you know the results.Start here:
Use you multimeter to measure the resistance of the A23 and A24 to body ground. Post the Ohm readings.
okau here are my results:Next unplug ECU connectors A and B. Turn the key to ON(II), measure voltage to body ground at A25, B1, A7, and A8. What voltage do you read?
Now turn the key to off, and measure resistance to body ground at A26 and B2. What resistance do you read?
is there a fuse for my fuel? is so where is this fuse?Fuel fuses...
