I have a 94 Chevy c1500. There is a junction block on the driver's side fender well that the HEI distributor wire runs to and I believe the aftermarket Holley fuel pump runs to. I was told it should be hot at start where is the wire that makes it hot located and I'm not sure if this truck should even have a junction block on the fender well. I'm stumped please help.

Check the positive side of the battery for a burnt fusible link. It looks like a wire but when it's over loaded if burns in half. Look at the pos. battery side of the starter solonoid you'll see a few of them there. Check your ignition module as well. This controls the coil and distributor and is mounted to the driver side inner fender.

fuel filter sounds like it is a prime suspect. if cat convertor it will be extremely hot possibly glowing as this goes on.

SOURCE: fuel pump relay for a 1994 Chevy Truck WT1500

The Fuel Pump Relay is located in the Glove Box under a little cover on the upper left side. The Fuel Control Relay is the left relay and The Fuel Pump Relay is the right. To test these relays, swap them and then try to start the vehicle, or blow the horn. If the horn blows then use that relay for the pump and you may at least drive the vehicle where needed! If the vehicle starts, then replace them as a pair.

open the intake manifold by removing the air cleaner and or hose look on the back side of the plate to see if there is varnish and gum if there is you need to do a top engine clean, You must understand that running that kind of gas will cause varnish and carbon buildup on the pistons and valves. This causes the knock sensor to not to be able to adjust for compression change. It can only advance the timing 50% once the carbon build up is to much it will start knocking. If you want to receive instructions on how to fix this then rate me post a comment and I will give you the two page answer on how to do this. Unless you want to keep buying parts. your choice. I will no longer post it here as I see some think they can just take my answers and copy them.
