While driving on the interstate today my engine dropped dead.just stopped.no warning ,no check engine light,no nothing.I did manage to get to the shoulder with no power.I called AAA and was towed home.I am getting no fuel spray from either nozzle.The engine will crank but will not fire.I have plenty of gas,and the fuses look good.Where else should I begin looking?I am hoping it is not the fuel pump as I understand it is inside the gas tank.Thanks in advance for all responses.
Tankman :eek:

 

CEASEFIRE!!!!!! :lolg: Sorry, couldn't resist. There are a few guys around here who know alot about the L83 engine. Hopefully they can help.

Twin Turbo?? ;)

 

Heck, it could be a lot of things, from the fuel pump or power circuit to the computer. No way to tell from here.

 

Check to make sure you are getting power to the fuel pump. Yes, it's in the tank, but not that hard to get at.
Just remove the tank lid, the rubber boot, and trim ring and you can then undo all the bolts that hold the sending unit / fuel pump in place.

have fun.

 

You called master????? :reddevil

Okay, you have no fuelpressure and the fuses are good.

There are a couple of things that can cause this situation

Bad fuel pump relay
Bad oil pressure sender or low oil pressure
Bad fuel pump
Hosed ECM
Injector harness broken or both injectors clogged

You need to have someone with good ears help you here.

Let him/her remove the gas cap and try to listen in the tank, next you turn the ign in the on position but do not crank, the FP should run for about 3 seconds to prime the system, if not, step 2

Crank the engine and watch your oil pressure, all good??? Remove your storage liner and find the FP relay, it''s bolted back there on the passenger side. NOTE, do not remove the wiper control relay (the one with about 10 wires coming from it) and see if it''s still held in it''s black plastic bracket with tape. If th tape looks fragile retape it. I''ve seen numerous of these units come off and short on either the jack or the jack retaining cable hook.

Okay let''s move on, the relay clicks with turning the key, it's good and so is the oil pressure sender or it wouldn't.

If not, it's either the oil pressure sender, the relay or the ECM but the relay is the most likely one because the storage box is a bad place to mount things (usually wet and leaking batteries are good for electronics)

If all checks out OK it''s bound to be the fuel pump which is together with the relay the most common cause of this problem

Removing it is a breeze.

Remove the gas tank door with ring.
Remove the bib if still on the car
Remove the gas cap and tape the hole
Loosen the 2 hose clamps on the right and the fent line clamp on the left . Carefully pull off the lines, special care must be taken with the small vent line, it's easy to pull it off the junction block on the tank but almost impossible to get it back on without removing the tank.
Unplug the pump and gauge float connector.
Now remove the 8 (?) bolts that secure the flaot/pump assembly to the tank.
Now comes the hardest part.
You may want to tape the edge of the hole where the gas door is mounted with some tape to pevent damage
Pull the whole assembly out bit and turn it, you''ll get the feeling for which way to turn, you need to turn it a bit, pull and tun some more and it''ll come out.
It's really close but it can be done. With a bit of persistance and carefully looking you''ll get it out fine

Then you need to swap out the pump and reinstall it.

There's a techarticle on the crossfire vault for swapping the pump
