hey everyone i got a 86 rx7 and my fuel in jectors aren't working at all. I"m gettiong fuel in the rail but not out of the actual fuel injectors
if any body know what this might be please help thanx

 

What little I know about fuel injection is that if the crank angle sensor is not working and sending a signal to the ECU, then the injectors will not pulse. So it seems appropriate to ask you *are you getting spark*? Or are you SURE your getting spark and just no fuel? Which in turn makes one ask you *are the fuses good in the fuse box under the hood?*, because one of those feeds the ECU. In other words I don't know, but check the above items and maybe you'll get lucky.EDIT: If he connected his battery **** backwards, then check the fuses in the engine bay plus those in the drivers compartment next to the left foot.

 

(friend here) HE hooked his battery up backwards and may have blown a few things....Anyone know what to replace that could be blown?

A WHOLE lotta stuff... The ECU is probably fried.

 

but my fuse went so I dont think too many things may have went and the car is turning but fuekl injectors are the only thing that is not working and i tryed to test it and it lookes like it might be it but I think there might be soemthing else as well

 

Interior fuse box. Fourth row from the bottom. Third fuse from the left. And while there, check them all. Only a ten minute job. Also the fuses under the hood. All of them. The ECU should have survived this episode. You need to buy a meter. When you do check the small white plug on the LEAD coils assy. Make sure you have 12v at the black and yellow wire. Check for spark. Take one of the lower lead plugs off and lay it near a stud on the shock tower. Turn the engine over with vigor and look for spark. If it sparks, the ECU should be triggering the injectors. Got nothing to do? Put the meter on one of the secondary injector plugs and look for 12v on one of the pins of the wiring connector.
