Guess what! I have another problem you guys can help me with.
So after replacing some wiring and what not, I still have an issue.

An '88 F-350 with a fuel injected 460.

So i've been having this not-start problem lately. It cranks over and fires and sounds like it is ALMOST there, but it never fired up. Yesterday I took a squirt of starting fluid and the truck fired up and ran. After a few minutes of running it shut off-- no sputtering, it just turned off. Another squirt of starting fluid fired it back up.. then it ran.. and did the same thing again.

Any suggestions of where to look? What to start with? Any sensor specificly I should mess with? Anything I can do to test it if so?

Thanks in advance!

 

bad fuel pump.

you have two, one in tank and one on rail.

 

The rail pump is kind of a "booster" pump isnt' it? Is it possible that as soon as the fluid gets it going that the rail pump is just running it for a little while? Or what? Also, I have two fuel tanks. Wouldn't I have a pump in each plus the rail pump?


Edit:
Okay so I just have the one on the rail and one in the tank right? But with front and rear tanks, which one pumps?

 

the ones in the tank are small, for carbs.

the rail one is high pressure for fuel injection.

i bet the high pressure pump is bad.

also you have fuel relays to check.

refer to your repair manual or owners manual as to where these are in your year truck.

 

Definitely time to invest in a fuel pressure gauge, otherwise you are throwing good money after bad. I end up using mine at least once year on one of the 5 vehicles I own. Best $25 I ever spent (I purchased it a few years ago from Harbor Freight).

 

On fuel injected engines, if you are having a problem the fuel pressure should be the first thing you check. you should put it right after you list the year and engine in your truck.

 

it will still come back that the fuel pump or pumps are nonfunctioning.

 

There is a fuel pressure regulator on your fuel rail it should only be about 25 bucks it sounds like the fpr went out and its flooding try that first

 

The regulator sounds possibly, its running rich and is a possiblility its flooding.

I am borrowing a fuel pressure gauge from a friend today so hopefully i'll get this issue figured out!

Thanks for the information guys. I will keep you updated and post up later tonight. (Assuming I got the gauge.)

 

then the regulator is probly your culprit in this case from the symptoms you just told me

 

How can I check the regulator?

 

how can it run rich when it will not start with out starting fluid?

 

is starting fluid bad for a vehicle?

my experiences with this chemical are limited, in the marines we used it to fire up the humvees 94-98. however the other day a buddy of mine said he would never use it on a vehicle (except a tractor) of his and said it was somewhat dangerous.

as mentioned before, we used it in the corps and we just squirted a bit into the fording stacks and they would start on a real cold day. i suppose that because i was paying taxes that they were my humvees just as much as any other taxpayers.

so, just how damaging is using starting fluid?

 

not in moderation.

i take a shot every few weeks and i run just fine.

could not be any worse for me then having a 'snickers and a coke' like you do.

 

yeah, i guess in diesels (humvee, tractor) it's not a big deal. i think my buddy was more worried about safety than engine longevity anyhow.



oh, i'm not into snickers (dislike peanuts) but i do like pepsi or coke, whatever.

the screen name "snickersandapepsi" comes from a joke very similar to his one Political Joke Archives - A Catholic Goes to Confession

being raised Catholic i found the joke being rather funny, it became my screen name years ago. fwiw
