I need some help

Here is the situation I just swapped a GSR motor into a EG and none of the fuel injectors are working

They are OBD I injectors

This is what I have tried so far

2 sets of injectors
2 ECU's
New Fuel Filter
Newer Fuel pump
I have voltage at the injectors
I have continuity from the injector to the pin on the ecu for each injector
All grounds are good

I am stumped

Anybody have any ideas why they will not fire

are they in the right location?

May sound stupid but do you have gas, and is there fuel presure.

Lmgrcivic

is the fuel pump coming on

iv

they are in the right order

I have gas and fuel pressure at the rail

The fuel pump is coming on

Colby71

do you have gas going into the cylinders? Maybe it is not the injectors.

iv

There is no gas coming out of the injectors I pulled the rail and tried to start the car no gas came out??

Then get a new fuel pressure gauge. You said it read fuel pressure at the rail, obviously if no fuel came out, there's no fuel pressure at the rail, get a new fuel pressure gauge.

Then see if you have fuel pressure.

Or maybe I'm understanding it wrong and there's fuel coming out of the rail if you remove the fuel pressure regulator - but nothing at the injectors, is that right?

If that's the case you don't have power going to the injectors, check the wiring from the harness. You said you tried two ECU's so I doubt that's the problem. Use a test light or multi-meter and make sure you're getting power at the injectors.

Blah, I just scrolled up and see you already checked that.

Hrm.

There's only one thing I can think of, and that's that you have power to each injector, just not enough power to open them up. Find out what it's supposed to be to open up an injector (12v at ?? amps?) and check that against what you have.

Weird problem.

Thanks anybody else have any ideas

Okay so I went and did some more checking of the voltage from the ECU and the injectors and the ECU is sending a ground when it is supposed to but the injectors are not firing

Could it be that maybe the fuel pump even new could be faulty and sending pressure but not sustaining it enough to start???

bruised eg

Check the connector at the left shock tower, the large 1 with the plug in it. If the plug is not there the injectors will not fire. Injectors are operated by ground, they always have power. Check all of your grounds again, especially the 1 at the thermostat housing.

iv

Done the plug is there they all have power and the ecu does send the ground pulse when trying to start

Unhooked ground and therm housing sanded it and put it back on no luck

I'm ready to beat this car with a hammer

Colby71

Well I have an ax if you rather beat it with that.

I got it fixed today

It turns out i had 2 sets of bad injectors go figure

Colby71

wow that sucks but atlest they are fixed.
