Hey all, Troy here again with another issue on my 1993 sundance., OK i have no codes and 1/2 a tank of fuel.
so here is what it is doing now and both those times ive had to work on the fuel before. it starts and runs and then out of no where we have no fuel.
so changed pump. started right up. drove for months.
did it again fiddled with the injector, started right up. drove for months.
did it again. this time on the side of the road. I still had the old pump. so i decided that i was going to see if the pump fired at all. it did. it didn't when it was in the car. So on the side of the road in dangers way i swapped the fuel pump again. started up drove it home.
I still had a couple things to tidy up under it before i was done so i back in left it out of the spot a bit. finished and now it wont start. same crap. i changed the filter when i did the first pump.
So now it hits me. every one of these times the car is sitting for at least 30 mins without a battery. plug it up and it starts. I am going to test it again tonight.

Could this be the sign of a failing computer in the car? or am i just really bad at fixing cars. lol (probably.)

Didn't start. pump is not pumping again. last time i had an issue i moved around the relays also. im so very confused. if it were a damaged or exposed wire wouldn't it be more often? could my crank or cam sensor be doing this? where are these sensors located? if these sensors were bad wouldn't i get a code? or would i need the car to run for a bit?

Thanks for the reply and info. I did try the gas in the tbi and it does start that way. pulled the fuel supply line and no fuel comming to front of the car at all. not even a drip. no fire from the pump. when the pump does fire after its random vacations the car starts right up. is there anything else that could cause this?
I may have to dissasymble the interior and check the wires from tank to dash just to make sure that its not a short causeing the asd to shut down. its the only thing i can think of at this point.

Wanna know the cool thing about safety relays? they save your [I should have my mouth washed out with soap for using such terms]. lol. I really doubt this was the root of the problem but the fuel lines were loose at the throttle body. that might have triggered the asd like it is supposed to. but the thing is the loose hoses would not have been the issue a week ago. the car is running for now. ill get back if it does it again.

ok having this problem again. i ran a wire directly to the pump. it works good. but wont start. the wire diagram i have shows nothing between the power and the pump but the ASD.

what do i check now?

The car surges when the head lights are on when it is running. sometimes the radio cuts off. the alternator was tested good and battery is good. could all these problems be from the same place? maybe a bad ground?
