Well, I tracked the issue down to a broken wire at the fuel pump. I must have been hearing the in tank pump when I jumped the fuses. Now i have to figure to how to reconnect it, because the plastic connectors on the pump have deteriorated and broken. Then I need to figure out where the brake lights are shorting, and I should be back on the road.

Thanks for the input!

I pulled the return line on the fuel pressure regulator and attached a long clear hose. Between jumping fuses 4 and 6 and cranking the car, I couldn't get any fuel to come out. So, it seems like I have a blockage somewhere. Is it possible for the fuel filter to become this clogged without any previous symptoms, or should I be looking at the fuel line itself. In-tank pump was replaced about 8 or 9 years ago, and tank is almost full.

Any thoughts?

Thanks

This happened to me with an 84. Found a broken tab on the Hal sensor and it was knocked loose. Put it back together and cranked right up.

Check the fuel pressure. Whether or not you have proper pressure at the injector rail will help you know in which direction to start digging.

If no, or low, fuel pressure, you can run jumper wires directly from the battery to the pump(s) to see if that gets it running.

Hi,

In reading over your post I was going to ask can you hear the main pump running?
You may have jarred loose a connection underneath the car going to the pump or the pump is old and is having trouble restarting.

Was the pump recently replace as some mechanics hokey the connections if they don't match?

I would go back to check out that fuse panel for corroded fuses. "Number seven blows occasionally?"
What's up with that?
You want to be rear ended or like being stopped so you can to talk to a few officers.
If I tried that, I wouldn't make it ten miles! It seems somtimes that I live in a police state.
Oh! I get it now. You use dirt roads! Not many cops on those as some cops have to wash their cars and empty out those fast food bags!


I think #4 and #6 are the two that if you jumper the left or right side to each othe will make both pump run.
Read the following and look at the pictures to help you get those pumps to run because I'm so vague!

Flab brings up a good point about the timing belt especially if you have not serviced the tensioner in few oil changes. Doubt the hole caused a belt to slip but when "its" time comes around and this thing goes around a lot, a good thumping can be a nice coincidental wake up call!

Enough times hitting holes in the road cannot be good for anything on any car.

I Hope Art's web site helps!

Make sure that your timing belt didn't jump a tooth. It's possible that some of these other sensors were damaged, but I hav had a similar experience when the timing belt stripped a few teeth.

I was able to go back this morning and check that the spark was good. Had my girlfriend turn the key, but I wasn't able to hear the fuel pump engage. Anything else I could check?

Thanks

Check ground wire to engine block from battery. If it came loose from the jarring, you may not be able to get good spark and injector operation.
