Fuel Relay Fuse Location - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi!

I've got an 87 Silverado with TBI and dual tanks.

Symptoms:
-crank but no fire
-will catch with starting fluid in the TB

Problem:
-No Voltage is showing at the Fuel Pump relay

I diagnosed this by removing the relay from the harness and using a test ligt on all 5 connections. My Haynes manual says that the Orange Wire is supposed to be hot at all times...

Haynes also says that there is an inline fuse between the junction box and the relay that is 20A.

Where is it? <---- I think this fuse is the problem...

Why? - I replaceed my radiator and when finishing up - accidently hooked up the battery backwards. Fried the alternator...Like I said before - everything seems to be working except for fuel into the engine...

Thanks for your help!
