what would cause this i am not getting any fuel to my plugs on the passenger side but i do have spark and fuel pressure.



what could be doing this???


89 formula 350 TPI auto


Thanks

 

I believe there are two fuses, one for each bank of injectors. Might wanna check that.

 

Yes, Two fuses inside car

 

going check on those now

 

THOSE FUSES ARE GOOD !!!!

Any other suggestions ??

I am lost with this. is there a relay or switch that could have went out???

I can actually feel the injectors are not pumping.but only the 4 on the passenger side not working!

 

No relay. It goes,,,

Ignition switch to fuse block to fuel injectors to ECM. First thing I would do is test each injector harness with a noid light to verify they're not getting power. If the light don't light up then you gotta go from the fuse block and start checking wires for power.

 

Thanks i will start chasing that monday i had enough for one day.

The cause of the problem should be easy to find since they are
batch fire injectors. According to the schematic, each fuse goes to
a pnk/blk wire which goes to four injectors. They then go to the PCM. Probably a loose connection where the pnk/blk connects to
injector harness. A friend had a similar problem with a car that had the TPI stolen before he bought it.

 

Well i got it! It was a loose wire at the connector on the ECM just that wire had backed out for some reason. She is running like she should now.

THANKS GUYS!!!!!!!!!!
