no gas flowing???

[homebru420]

So the new Edl. carb and intake are all hooked up and ready to go...but I got no gas!

Friday night I had everything hooked up but the throttle cable and tranny kickdown. I turned the engine over a few seconds and then jiggled the throttle on the carb and to my delight, gas flowed in to the carb. Saturday morning I went out and hooked up the throttle and tranny, manually put the timing about 5 degrees BTDC on #1 cylinder, and cranked her up...many times...nothin'. Not even a sputter.

So I started checking stuff out...finally removed the gas line just above the fuel pump (to eliminate poss. of clogged filter) and let the hose drain into a cup while I cranked the engine, again and again I cranked...no gas coming out. :confused:

I just put that fuel pump in about 5K miles ago, but when I pulled my dipstick...the oil smells like gas and is real thin on the dipstick. :eek: Anybody else have a fuel pump go bad this fast? Do the diaphragms in these things really bust that easy? Since I had fuel flow one day and not the next, could I have done something to cause the diaphragm to rupture or is it really that catastrophic?

Welcome to world of Taiwanese auto parts :(

It's not just the generic offshore parts (though they are frequently bad); Holley fuel-pumps for the Olds motors are notorious for rapid failure. Ah, sometimes they go. At least it wasn't while you were driving! Change your oil and your pump, and you're on your way.

BTW, I've had good luck with used pumps on my trucks staying alive. I reused the old one on my Cherokee with this new motor; turns out when I cleaned off all the grime that it was a Carter Hi-Flow pump! :cool: Not that the carb needs any more fuel, but it's nice to know that it isn't a no-nameer either.

Of course, many "name" parts are sourced from overseas anyway; the same manufacturer pumps out parts for Purolator and for the generic bargain store-brands, puts them in different boxes, and you pay more for the same part (this is true for the air-filter I just picked up for my GW).

I now have the same #@!% problem!! I spent the last couple days in the blasted heat we been having, puting a rebuilt 360 in the wifes 89 Grand Wagoneer. NEW, Edlbrock 1406, Performer intake, fuel lines filter and pump. Turn it over and no fuel, pull line off the carb no gas hook up my vacum pump and I can pull fuel up. turn over again with the hose off the carb, fuel pulsates out but with NO PRESSURE!! Now I am upset!! I will never buy another off the wall brand fuel pump. :mad:

Crazy Jeepman...I too have found how wonderful it can be to run into these problems in the 90 + degree heat...with Michigan humidity no less!

Ain't it grand?

Hello from England!

I Can't resist my halfpenny's worth here! My business specialises in a rare, fibreglass British sportscar called the Scimitar. It uses 3.0 litre V6 Ford engines of a similar vintage to the AMC V8's with the same cast iron engineering!
Because fibreglass is such a good insulation material - especially when compared to steel and because the airflow through the radiators is marginal on these things, these cars suffer badly from fuel starvation in summer months (yes, we do occasionally get a summer over here!)
Mainly to address this problem, we always install electric fuel pumps. These are available in a variety of outputs and with a variety of fuel throughputs, but they almost instantly eliminate the fuel starvation problems. They also have the huge advantage that if you ever run out of fuel, the fuel can be dragged from the tank to the engine without having to simultaneously crank the engine and therebye flattening the battery in the process.
They can be wired through a concealed switch for security purposes and must be wired through an impact switch so that they shut off in the event of an accident.
My Grand wagoneer will be fitted with one (or two?) of these devices for certain as part of it's rebuild.


Hope this info is of use.

Cheers,

Paul.
