87 supra wont start on its own

gamer565 · 02-05-2009, 04:38 PM

I did a NA-T swap(7mgte) in my 87 and finally got it to run today, but it needed carburetor cleaner sprayed into the intake tell it could run on its own.

the timing is correct, the fuses are good, theres good fuel pressure, everything is connected correctly. and as far as i know there are no codes being thrown.

i think its the cold start injector, will a 7mge injector work?

No, but thats also not going to stop it from starting. Something is not letting the injectors open obviously if you have good fuel pressure and everythign else is good. Use a noid light to check if you are getting power to the injectors

did you install and connect the cam sensor?

doesnt the ignition run off the crank sensor where th fuel injectors run off the cam sensor?

pretty sure... but not positive..

just something else to check

Thats kind of typical in a modern car but the supra runs the ignition off the cam as well

Update time

code 51 is the only code that its showing
the CSI is getting a pulse, fuel and the ohms is 3

the cold start injector switch is not getting and power or a pulse, should it be tho?
