Archived 93 Died on Freeway - makes no sense.....

[JStangeland]

Rolling down the freeway, my work truck just up & died on me. It's a 93.

Had my tools on board so I got to some diagnostics.

Definitely have fuel, confirmed fuel delivery to the injection pump.

My gauge doesn't work exactly right so there've been a couple of times I ran out of fuel, so I dumped some in the tank and cracked the injectors, got fuel at them and tightened back down and it started right back up.

I did the same deal this time but am only getting fuel at the #3 & #4 injectors, all the others aren't giving me anything, totally dry. ?????

Why only #3 & 4? I cranked & cranked (pausing of course) until the battery drained. Big air leak someplace? It was running completely fine up until that moment so where would it have come from?

I called AAA but they wouldn't tow me because I have a utility bed full of tools and plumbing parts and it would've been too heavy for their equipment so I had to call a commercial towing outfit and give them $180. ouch.

but it should've started. I'm completely bewildered. I have all my tools and parts aboard so I need to get it back on the road asap.

Can you check if the return fuel check valve failed?

If it wasn't getting fuel I would of said the fuel shut off solenoid.



So lets go with your VE is messed up. I don't know much about them except they are mechanical rotary pump. But the symptoms are similar to the VP44 being messed up and it a electronic rotary pump.

I'd check the connection to the fuel shut off sloenoid. On my first '93 I had, if I hit a bump just right ( wrong?) it would break the connection just enough to shut it down. Pull it off give a gentle squeeze with some pliers and see what happens.
