So you have some fuel issues. Could be a lot of things. Fuel pump, filter, fuel line, fuel pressure, a leak, wiring, fuses, replays, etc. Anymore info you can supply us with?

Did you run it dry and the fuel pump burned up....or someone else did?

2 of 2 people found this helpful.

searching for an impact inertia switch....if the power to the pump has completely shut-off...there is an ASD automatic shut-down relay that will drop out too, if the car thinks a fire will ensue~

i think i am going to have to find a code reader.. to see which fuel injectors to replace if not all... however this has sooo helped me to not have to try all the tiny lil stuff that is still good and not the issue as i see alot of people have issues with this car noone has ever said how they fixed the issue???

ummm... is pulling fuel injectors from another typer vehicle that uses same injectors that may be just fine a ok idea?? or is it just as decent to not spend all day doing that and just order them? in case after all it may not be them injectors as i hear so many others with the same fuel issues ...???

1 of 1 people found this helpful.

....okay, never known an injector to be faulty....perhaps can be clogged with rust particles...BUT the fuel filter should have caught all that to perhaps a 30 micron level of filtration~...so don't bother with a "franken-car" results will NOT be acceptable at best~

buying the code reader good thing to have for most usually anything i suppose and i am so new to the shopping via screen view and card swipe lol i cant touch feel inspect but i am learning so 15 bux for the reader and i am thinking 162 for a set of 6 injectors same pic as auto zone wants 275 for will have to do...... i was thinking i did not want to replace what may work fine... seeing as i dont have a real mechanic just a guy i once dated a million yrs ago whos father made him work on cars and learn a lil something.. all the while teaching my son to work on his own cars notice whats wrong or right with a car you drive and such ahhh i appreciate the helpful things you have mentioned... the car we grabbed had been sitting about a year we live in the desert as the photo displays .... and a summer of extreme heat... it just needs to run like a good car should 10-15 miles a day ....

so far fuel pump is new, filter, and separator... also got a new fuel pump relay cause it was cheap ... did a tune up, the ecm is fine and the only other thing mentioned anywhere was the injectors so i guess the code thinga magiggy will have to do.... i am sad i didnt mean for this to be such a project i am sad i rarely make such bad desicions its a good car tho body, etc cared for ... my 18 yr old son is sad he thought he would be out driving today

1 of 1 people found this helpful.

pull the injectors and spray "gumout" seeing as the fuel system is VARNISH by now...drain the tank and use fresh gasoline...the expensive 91 or 93 octane stuff...change out the fuel filter....run the old stuff out of there capturing it in a fuel can and make sure "fresh" fuel only to the injectors...clean them with gumout~

okay if the model/part numbers are the same for the injectors...why the hell not~?

and in the buying of the infamous code scanner.... all i see is scanners that work with cars 96 and newer.... xcept these dino looking gm readers that show via the check engine dash??? gosh golly .....

...weil there "should be" a diagnostic port OBD-II within three feet of the ignition switch....sorry did not check to see if this scanner will work....okay, what you have to do now is count the number of flashes with a certain diagnostic jumper in place....refer to your owners manual to find out how to do this~....and what the number of flashes actually means~

The Queen has now arrisen and on the way to try to solve they mystery. Since taking to our dear friend who knows how to do work on cars ... we have got her st start and drive a few feet doesnt stay started longer than that. :(

Fuel pressure test kit how thw heck do u connect it

1 of 1 people found this helpful.

on the fuel rail (you know where that is) [upstream of the injectors] you will find a 'shroeder' valve {like the kind that bicycle tires use} push the tester onto that with the pump running to find the pressure 70 psi is a good pressure...less is okay too...depends on how high this injection system is supposed to work at - ---will have to research that...now my foods goin' cold.~

been thinkin' on your problem and most automotive problems start from insufficient system ground in the form of corrosion between the main 1/0 battery cable and the frame that it bolts to....have someone take out the bolt that holds that main cable onto the chassis and wirebrush the lug till shiny...at the place that it bolts to as well for a restored 12.5 volts ground potential~
