Name isXXXXX goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

When you say dash light do you mean the ignition and warning lights are on .

What happens when you turn the key to start .

Greg
Customer: replied 1 year ago.

Nothing happens when I turn the key..the engine check, seat belt, and arrow lights stay on with no key in the ignition. When I put the key in...lights go out and engine won't turn over.

Hi Ralf .

Okay this looks like a ignition switch problem.

The ignition switch on this model is on the steering column .

As shown below .

This part is a cheap item that you can get at most auto stores like AutoZone ,rock-auto etc NAPA .

Need further assistance then please get back to me with the reply box and not the poor or bad service button .

Greg
Customer: replied 1 year ago.

Hi. I pulled all fuses and all relays and lights remained only when I unplugged the ecm module that they went out, thats why I got a new ecm.

Did you have this problem before the engine was replaced .

Greg
Customer: replied 1 year ago.

Well, not sure, its been sitting for about 2 years maybe 3 at my ex son in laws...not running...sold it to him...when bought it back after his death from an accident. So I do not know..when I sold it to him eight years ago it ran fine. So not sure really.

Expert:  Greg replied 1 year ago.
Hi Ralph .

Sorry to hear the bad news , was the accident with this car .

Clip the fuse box and open it up and look under it for rodent damage .

Greg
Customer: replied 1 year ago.

No was not with this vehicle....its was not running at least 3 years. Ok I' ll check out and let u know.

Customer: replied 1 year ago.

Ok. Thinking about it, its clean...all wires checked...I had fenders removed and powder coated....all wires checked and connected.

Customer: replied 1 year ago.

Any other suggestions?

Customer: replied 1 year ago.

Hi greg...whats common in the ecm to make check engine, up arrow, and seatbelt light and gas tank gauge reading full when it is bone dry...

Expert:  Greg replied 1 year ago.
Hi Ralph .

So sorry did not get to you sooner been traveling and also got food poison ,but now much better.

Can you disconnect the fuel gauge wire at the tank want to see if the gauge drops back to empty , but looking like behind the dash is your short in the wiring harness.

Rgds Greg
Customer: replied 1 year ago.

Did that, gas gauge still says full...sorry...I am pretty knowledgable myself about engines and cars..but do you think still can be a short behind the dash..

Expert:  Greg replied 1 year ago.
Hi Ralph .

If after disconnecting the gauge at the tank and the gauge did not drop then in the wiring harness from there to the gauge is at fault ..

To be sure the gauge is not the problem pull the gauge cluster and disconnect the fuel gauge , check the wiring .

Greg
Customer: replied 1 year ago.

Hi greg...removed the dash all wiring is intact from what I can tell..nothing bare, nothing freyed...what now?

Expert:  Greg replied 1 year ago.
Disconnect the fuel gauge wire does it drop or stay high .
