Melting

[tery]

Hoorah...It melted, there's actually blacktop under them thar ice sheets...so naturally I had to take out one of the girls for a spin. Babe, she ran very well, but of course I still have that original cam seal leak from last winter, We'll take care of that one way or another this summer. Anyway...a question for the experienced Chauffeurs ...I was just getting down close and looking over the intake manifold and vacuum hoses that are getting dry etc and I noticed a not too strong smell of gas near or around the those two diaphragm looking valves on top of the fuel rail right inside the long left side of the intake. I didn't see any wet, like a leak, but am just wondering if I should be able to smell gas. Seems like not, but maybe that is normal>>>???

And is it a vacuum hose coming off the side of it? It doesn't seem very tight...I'm guessing if it were fuel, it'd have to be clamped, but it isn't so I think vacuum line, but still, not very tight on it's ******. I didn't pull it off cause it was getting dark...THoughts??

edit...Looked on the pheonix site and see that these lines I'm asking about are fuel,..but shouldn't they be on pretty tight, I'm thinking that the rubber is old and kinda brittle and so not fitting on as they were intended>>>

Are you talking about the fuel pressure regulator (on the DIS side of intake), Tery? That would have a vacuum hose coming off the side of it. That's not clamped. The FRP could be leaky or could have a cracked fuel hose. Any problems while starting or driving?

 

[rubydist]

the one with the vac hose attached is the fuel pressure regulator, the other is just a pulse damper. They both have little diaphragms in them, and it is possible for that to leak. The loose vac hose should be replaced (along with likely all of the other vac lines) to make sure there are no vacuum leaks.

If the vac line is not attached well, it is possible that there is just a little fuel smell from the manifold, but it is also possible that the fpr has a bad diaphragm.

Thanks for the reply...yes on the DIS aide of the intake..

THank you Fred,...I didnt think I should be smelling fuel. I'll replace the hoses and see if the smell goes away, I haven't looked closely, but can I get off and on the other end of the hose without taking apart the intake??

and,,,starting seems good, She's got new timing belt, plugs, wires, and coil. Maybe cranks a little longer than I would expect, like3-4 sec, butwhen I let off the key she kicks in.. If that diaphragm is leaking...maybe it has to crank for a bit to bring up the pressure>>?? Does that make sense>>

3-4 seconds isn't all that long, especially on a Ford. Now, on my Saturn, only 1 turnover was required to start the engine, every time. Different design philosophies I think.

What about cranking and then when I give it 3-5 inches of gas pedal or a pump or two and it kicks over...*((this is with Chastity, whereas this thread was started with Babe in mind...Chastity is MTX)
I'm used to not giving any gas pedal on newer cars to get it to kick over. When I first started driving you always had to give it gas when starting, is that also the case with the SHO motors and fuel set ups?? I thought that injectors weren't supposed to be primed so to speak with the gas pedal?? Maybe if the diaphragm is leaky, the pressure is gone when I go to start up?? THoughts

 

[SHOdded]

Are you basically putting the pedal to the metal? Then you are cutting off the fuel pump while starting, which likely means you already have fuel in the engine. This could be due to leaky or stuck injectors. Less likely is a weak ignition system. You could pull the plugs after cranking (without pedal pump) to see if they smell of fuel. In any case, pulling the codes first is always a good idea.

Man, you guys are terrific, I'm just starting to try things out here and noticing what's off and on with the cars., now that the ice age has ended, just putzing around so to speak, I've got three months of school, then I'll be free all day every day and can really dig in and get these girls in shape!!

And....so if I pull a plug after some cranking with no pedal and there is no fuel, then I've likely got a pressure problem, like maybe Fred's idea of the fp check valve..., and if there is fuel smell or even worse...wet...on the plugs after cranking no pedal, then maybe leaky injector, such that alot of pedal would be like in the old days where you hold it floored while cranking to clear out the cylynder??
