Default 88 dodge truck fuel pump relay

Anybody know where the fuel pump relay is on an 88 dodge pickup/ramcharger? I just replaces all the lines, started it up, ran it for 10 minutes and it dies. No fuel at the TB supply hose. It doesnt sound like the pump is running at all, i figure I should check function of the relay before I pull the tank again :stan3:

you can get the connector off the tank to check for power at the pump without dropping the tank. I'm not sure were the relay is but im guessing it's one of the ones on the drivers fender

According to the just short of useless haynes manual, none of the three on the driver fender are the fuel pump. Unless it is called something besides "fuel pump relay". They showed one for MPFI engines, but not TBI, and I couldnt find any relays on the firewall.

And I know I said truck, but this is for a ramcharger - no go on checking the pump connector with the tank in place... You cant even stuff your hand between the tank and the tub floor

K I just searched ramcharger central. Apparently the ASD or Auto Shut Down relay IS the fuel pump relay - on the driver fender
Too bad Ill have to wait till next sunday before I can look into it again = /

Ive also learned that if the ASD relay is bad, there will be no spark. Well I have a good spark for sure.

Priced a new pump through the zone website, $79..... I have a like new holley blue laying around from an old project of mine. I think Ill try and run it instead. I hear you can run a blue without a regulator on TBI setups?
