Well last Friday, drove car to work, been driving it on and off for a while. Get in it in the afternoon and no start. Cranks but no buzz for the fuel pump. Do some looking, fuses seem ok, relay ok, then notice the fuel gage is pegged past full, and the parking lights will not go out, no key on, switch off, lights on constant. Only way to kill them is disconnect battery.

Car has a Viper alarm installed, bro had it done before I got it, so am thinking maybe something is up with that. Call Viper, they say their kill start system is just that, no cranking at all, does not affect fuel pump.

So maybe I have a bad pump, ok.

Any ideas on the lights. I am pretty much stumped about that, and the gage being pegged.

Maybe time for another V, hate unreliability, luckily it's only 40 miles home and have some very good friends to drag his trailer down and pick it up.

Does the pump prime for 2 seconds when you turn the key to "run" (not "start")? It's normal to shut down after 2 seconds, and will not restart until the PCM detects the cam position signals from the Opti. Scan for codes.

If the pump does not prime at all, try powering it up with the fuel pump test connector near the PCM (at least that's where it is on an F-Body). If still not powering up, check the relay and check the harness connector for the fuel sending unit near the rear axle (again, based on F-Body). The fuel gauge being pegged generally indicates an open circuit. High resistance = high fuel level, and an open circuit has infinite resistance.

I had a viper alarm once, worst thing ever in my car. Would randomly not crank or anything and everything would just shut off when trying to crank. Then the car would do nothing for 10 mins. Then suddenly work.

On an impala, check the grounds in the back, they all go together

I have not checked the relay in the back by the tank. It has a hot wire fuel pump deal, harness goes right to the alternator picks up voltage off the battery, that is all good, relay in the fuse box works, fuse is good. it ran in the morning when I drove it. And the tank is about 1/2 full.

I tried using the disable feature on the alarm, still wont start, just cranks, and there is fire at the plug

Well its up and running. Apparently the turn signal switch in the column or something in that area is shorted, and the hazards are not to be used, something must be going on. We are changing that out while he has it and the cats are also bad, blowing chunks out the tail pipe, so need to deal with that as well. Might just be time to pull the ole 160k mile LT-1 out and do a fresh rebuild, nice alloy heads, proper headers, cam, and I am tired of cleaning up oil every time I move it.
