When it is needed, it should be done immediately to prevent any injury or damage, as leaking fuel is never a good thing. The only high pressure flex line is on the outside of the tank that goes to the junction manifold. A possible cause would be the head gasket blown between the two cylinders. The fuel system is made up of 4 major components: the fuel pump, fuel filter, fuel lines, and of course, the gas tank. Double check for vacuum leaks but it sounds ignition related because a cold motor puts greater demand on the ignition system. Bryan Wood The F-150 is a hard working truck, except for when it fails on the job and refuses to start. The later type uses a rigid fuel rail to hold the injectors down to the manifold as well as seal to the O-rings.
A poor fuel pressure regulator can also cause your Ford to stall while idling or driving. This design has been well proven for over 30 years. Another bit of info is that when I open the throttle all the way up from idle goosing it it sounds like it chokes for a second then revs up. The power ratings discussed above are for each injector. I don't mind spending money on the system to get it going again, but dollars are tight and I don't want to keep playing this game of replacing everything and hope I got the bad part in the process. Does your truck feel like yourself on a Monday morning after a weekend of partying? When I stop at a light I have to put the truck in neutral. Repeat several key turns and note pressure.

Avoid cranking the starter for too long, or you will burn it up and add the starter to your list of needed parts. I did a seafoam treatment last weekend and run a bottle in the gas tank. Most injectors of all brands built after 1974 use the later type. A bad component in the fuel system can cause a variety of problems with symptoms such as hesitation, trouble starting, and the feeling like it's dying on and off. Two affordable options are: Auto Zone Advance Auto I went with Advance Auto because it was a dollar cheaper and came with a new gasket.
The D-Jetronic type used from 1967 to 1973 or so on Bosch injectors in which the plug fits internally into the injector and the L-Jetronic type in which the plug fits over the injector offreing a waterproof seal. I wanna see that motor in action, aside from the E303 cam, its the way I wanna go with mine. Save yourself some money and learn to diagnose your own non-starting Ford. Are these the original fuel pumps? Raising the pressure to extreme levels is very hard on the pump and can lead to leaks or failures in the plumbing and injectors themselves. The easiest way to test is to spray starting fluid into the throttle body while it's dying out; if it picks back up, the problem is fuel system related.
When driving from a cold start, the engine pops a few times as I am giving it gas and the truck doesn't respond well at all to the pedal. I am at a loss on this drop in fuel pressure. I put them both back on and then unplugged the trucks computer over night. While testing will need to be performed to verify the failure, if any of these symptoms are present, a faulty fuel pressure regulator may be to blame. For this injector, that gives a mass flow of 30. Every motor is comprised of several. If it is equipped with a fuel switching valve instead of just pumps, the switching valve is probably bad I got under the truck yesterday because I kept reading about a fuel selector switch and wanted to see if there was one on mine that may be bad.
I am about to go check compression on it just to be sure they are all in spec. These are very inexpensive, simple, and reliable. Well about 2-3 months ago I got the truck back together and drove it home and noticed it really didnt want to start and when it did start it would really stumble under acceleration. Power loss can make your truck a nuisance to drive and be indicative of other problems you may have. It shows where the fuel pressure test port is and how to test. . It's important to know the fuel system components and how to diagnose a related problem.
Can anyone tell what the fuel pressure should be on my pickup. Any test to rule out the switch, since it appears to be the easier of the two to replace? There is no need for it on my truck at all. The E303 cam in my opinion is not so good for everyday local driving. Hi, engine is stalling, apparently due to low fuel pressure. Ford doesn't make them, they buy them from Walbro and possibly some other sources. Does this happen on both tanks? With ground leads from rear fuel pumps disconnected from battery, there is no pressure or fuel.
I have a 94 that should be about the same though mine has the 5 speed. But when it cools down it starts right up, until you put it in gear to move it, it shuts down, do you thing its the oil pump? Older type injectors used a square section O-ring slid over the pintle cap to sit against the steel injector body. The trend lately is to use high impedance types in most production cars. To help rule out plugs, check them for spark and make sure they're in good shape. Thinking it might be a fuel problem, I run a pressure test today and here are the results.
