Fuel Pump/Tank: Update post 40

Mike, on a return style fuel system the pressure should bleed off pretty quick after you
kill the fuel pump. you might try bypassing the intertia switch or relay to rule those out.

Mine always help pressure quite awhile.

Checked timing, dist was loose. Set it and car picked up, but still dies after about 30 seconds. Pulled codes again, 14-pip sensor. Its Sunday, so I guess im going to have to roll a parts store distributor for awhile.


nice blueish white spark,, no orangeish or the stator or tif is bad.

here is what i found wrong with my stator once,, it was an assembly line cold solder joint on the black wire.

If you can get to it,, prob the black wire then bond it to chassis.
also stick a more stronger magnet down in the dizzy to pluck off any debris that might be on the hall effect or magnet.

notice below the high amounts of corrosion on the bonding of the bare jumper female plug and the black wire.  the black wire litterally was just barely hanging on.

No dice on a parts store dizzy.

They all have cast gears, even when specifically labeled steel gear. Every store carries the same Cardone.

Hell, can you even buy a distributor at the dealer anymore?

If I cant get Ford, what should I do? I have read MSD is all china crud now...

Buy a Motorcraft stator and replace it. That's probably your best bet.

Brought home an 87 today, 5.0, 121k.

Trailered it from San Antonio.

Should have swung it by my house.  I have almost a complete car in spare parts.

I disagree.  It should hold pressure for quite while.  If you do see it bleed off quickly, you need to replace your flexible fuel line in the tank or the pump itself (because the checkball is not working).  Holding the pressure up helps prevent the fuel in the lines by the hot engine from turning into gas and effectively causing vapor lock at the injectors.  Making warm/hot starts very difficult.  Old Bosh mechanical injectors were plagued by a similar issue due to the operating pressure of the injectors.
My car is a gravity hybrid.  The gasoline engine gets me up the hills, and gravity gets me down.

Well, it aint the distributor.

No change. Im back to thinking fuel. The way it dropped pressure as soon as the car died and was at 32 max to begin with just makes me think that.

Ill pull codes again later to check it out. I sprayed starter fluid in the intake, fired right up, dies after about 5-10 seconds.

Going to kickboxing to vent some frustration for now.

If the car has been sitting with the same fuel in the tank it could have gone bad. Modern gas doesn't store well for more than a couple of months. Maybe drain out what is in there and replace it with fresh stuff and see what you get.

He put chrome mirrors on it at some point. Im going to swap them back to black, so if somebody wants them...

Its got a blue interior unfortunately, but its clean. The seats are sun bleached so they are an ugly shade of blue. The carpet and dash dont really bother me, so I may just get the seats recovered or dyed, dunno for now, not a priority.

Owner claimed to have drained the tank, Ill see how long the current stuff has been in there.

Hey, do these take the same pumps as Mustangs? Wondering if the sock is any different, too.

Id like to order everything before I drain the tank.
