still injector issues: d15b7 non vetc - 93 hatch

[dirty-rice]

still cant get the injector's to pulse......fuel pressure is good.....ecu is good......wiring is stock.....if you pull off fuel rail, and take out injectors, fuel comes out....put injectors back in, no fuel.....the injectors came off a running car......the main relay is good and working.....the motor has good compression....any guru's please help :thinking:

im still wondering what it could be............

[scttydb411]

did you try cranking it with rail off car, but injectors still in rail to determine if the injectors are actually spraying fuel?

[dirty-rice]

yes i did.......fuel builds pressure but the injectors will not pulse fuel threw them........i changed to a new working ecu and still no fuel.....it fills up in the rail then stop and wont pass through the injectors........i put fuel in the motor directing and it ran 4 like a micro second.......what do i try next?

[pinedo88]

try another set of injectors.

What engine did you get the injectors from? IIRC, the D15B7/Z1 are "picky" about injector swaps and usually work only with injectors from the exact same engine. If the injectors are from a different engine, even if it a D-Series engine, they worked prior to swap, they might not work with that engine.

we got the same injectors we had

yes they are spraying fuel........well fuel does go to them, but not through them
