Hey everybody. I have an 87 1800 2bbl 4x wagon and just installed my new Weber Carb. Now I have no power to the Fuel pump. Did hotwire to another battery, the pump works, did change Filter. Only thing unplugged electrically was the one directly into the cutoff on the old Hitachi.

 

Has anyone had this happen? Is there a relay? The Hayne's says no on this model ( Carbed). I've heard the ECU supplies ground too and this may be burnt out. but how do I check? Also, how in the world is a Fuel pump only supplied power in the "ON" position but not in the "RUN" position??? I'm going by a wiring diagram. Doesn't make sense.

 

Oh, ya, The fuse is good too.

 

Any tricks or troublshooting tips would be awesome!!!

 

THANKS!

I found out to check the Rev Sensor behind the driver kick panel. Heading out to get-r-dun for class tomorrow.

Did you check the fusible links in the box mounted on the coolant reservoir also?

I did check those. I figured out the FPCU is bad and just hotwired to the Fuse for the pump with a piggyback. Runs great! Man this Weber is better than I expected. No tuning either.

You can do that alright but you defeat the safety feature by doing that. If you have a bad accident some serious things could result. Something to consider at least.

Thanks Cougar. I'll feep that in mind.
