Hey there, first off, looking for some input on wiring a temporary inline fuel pump. Where's a convenient spot to get my power from, without needing a toggle switch?


now some reasoning and info as to why I want the inline pump. I bought this blazer for 300, was told it needs a fuel pump. Tested, and it did need replaced, so bought a new one, and after installation I noticed the security light flashing, no fuel. Did the passlock bypass, spliced yellow Into the orange/black wire, key on, key off process and got nothing. The security light went solid and stays on for HOURS with the key on or off. So i ran a new power source to the fuel pump from the fuse box and pump still doesn't prime, assuming I have a ground or wire harness issue. So I'm going to run an inline aftermarket pump while I gather parts & $ to get a new wire harness, passlock components, fuel lines, ect...

just need this thing running to get to work, kids to school,ect.. for the meantime, and I'm curious if there's a safer, cheaper more convenient spot to get my power than the fuse box or directly from the battery with toggle switch?

thanks

 

I heard that you can't suck through the factory pump with an inline....let us know.

 

Not going to work, did you check for power to the pump? What brand of pump did you buy?. I would only use AC Delco or Delphi. The others are junk

 

I was just going to hollow out the old housing, rig something to work temporarily, pulling through a hose/tube only

I have power at the relay and not at the pump. Why I'm thinking I need new wire harness

now I'm reading that the passlock effects the injectors, not the pump... So I'm wondering if I could run a temp power wire to injectors also? Or would a steady 12v not operate them correctly? Do they run off a "pulse" or something?

just need this thing running tempoarily to finish a house and get money to fix it properly.
It's an a.c. Delco pump

I don't have much experience and knowledge of newer vehicles, I like my old carbed vehicles. Lol
