Welcome to the forums.

Got dash dash lights ,headlights, radio? Things of that nature still work?

Check fuse panel, make sure all fuses are good. That is best place to start.

Welcome to the forums.

Test light/meter time. Fuses OK, but is there power on them? Is the ECU power relay working? Fuel pump relay? Do you have a manual available? I would start by making sure I have IGN power when the key is turned.

we have spark when we pull the spout out and it starts with starter fluid (no fuel ) the pumps work when you bypass them I will get more info for you

So, you have spark. What is the measured fuel pressure at the rail?

No pressure at the rails( don't hear the pumps when you turn the key )no spark unless you take the spout out!
Pumps are fine we bypassed them and they started up! Relays appear to be good and fuses it is probably some thing really simple!! Had a similar problem last year turned out to be the stater in the rebuilt distributer so we put a known part in and that worked! This time 3 times in the last month it wanted to shut off while driving for like 1 second then went back to normal conditions?
Now it just shut off while running at a stop sign! Now cranks but won't start

I assume bypassing the pumps means you jumpered the test point to ground and the pumps run. This proves out the pump relay and the electrical circuits to the relay and pumps.The question is, do they build pressure? You could have a plugged filter, or a faulty fuel pressure regulator. You won't know for sure until you put an actual pressure gauge on the rail. Look for 30-35 lbs pressure.

Have you tried jumpering the pump test point to ground and attempted to start the engine while it remains grounded? Basically, this bypasses ECU control of the fuel pumps. It won't harm anything and will prove if you have a viable fuel system. Don't leave it bypassed while driving as it is an important safety feature. The ECU basically provides this ground, subject to an internal 1 second timer. PIP signal from the running engine's distributor keep the timer refreshed, which keeps the ground on the fuel pump relay, which enables the pumps, which pressurize the fuel. If the engine stops, PIP stops, the timer runs out, the ground is released and the fuel pumps stop. Very handy for preventing fires.

I would suspect a bad computer (PCM) since the pump does not prime and no spark unless you pull out the SPOUT plug.

Grab a jumper wire then do this: How to run a self test (assuming your truck is OBD-I.

Post the three digit codes you get, by number, and when they were displayed (KOEO or CM). Do not be surprised if there are none, another common failure mode with a bad PCM.

Well, you made me get up off my fat keester to have a look!

I have a 1997 F250 4X4 with a 5.8l in the project pile. Build date 12/96. It definitely has OBDI. You may want to read some discussion of the subject here;
http://www.ford-trucks.com/forums/32...1-or-obd2.html

1997 was a strange year for Ford pickups. The F150 got a new body, but fitment issues with the popular diesel engine forced Ford to keep the old body style for the F250/350 for another year. They got a new body in 1998 along with new power train choices. Now, anything is possible, but it just does not make sense to retool for OBDII for 1 model year. Heavy trucks were still exempt from regulations forcing OBDII, so I find it hard to believe any 1997 gas powered F250/350 trucks were built with OBDII. 1997 was also the last year for the 5.8 engine.

OBDI connector is in the engine compartment by the driver side hood hinge. This is where you did your fuel pump bypass test, right? OBDII is a 16 pin connector located near the driver position inside the cab.

Anyways, jumper game back on.

We run through this topic (OBD-I vs. OBD-II) every few weeks. Yes it's possible the OP has an OBD-II 1997 F250. Typically they are California emission F250/350 models with a 7.5L engine. In all things Ford there are examples that do not fit the template and their own service documentation.

Then there is always the F250 Light Duty that has the newer body style and modular V8 engine.

I'm sure with your directions on where the connectors are we all will know soon the answer to the question!

Yup, CA in his profile. Good call!

You never know what crazy regs they pushed through out there. They do seem to become the test market for the latest pollution controls.
