Like the title says....I'm trying to post a video but its taking forever to upload. While trying to crank the car te Rpms stay at 0. The tach isn't bouncing or anything. Only thing I did in the past 2 days is remove my radio and plugged an in the antenna cable in the back of it, and reinstalled it. Went to start it up to go to work and that's when this happened. Help!

I should have mentioned that the car is bone stock as far as the engine goes with 89k miles on original motor. My symptoms are identical to this guys.... I'm going to try some of the same trouble shooting this weekend.

after going out and checking fuses and what not, everything looked ok. checked the fuel pump relay under the dash and that was not blown. voltage at the battery (brand new battery) was 12.35 volts before starting. im alone right now and don't have anyone to crank the motor so I can see where it drops to while cranking. however, I did notice that when I turn the key before starting, I don't hear the fuel pump priming. I checked about 5 times. I turned the key then stepped to the back of the car to listen and heard nothing. if its not priming, what could be the cause of this? where should I check next? also I unhooked the battery for about 10 minutes hoping that that might reset something (ECU) but that didn't do anything either.

also I did notice that when I was at the battery disconnecting and connecting it back, none of the relays under the hood were clicking like all the other cars ive messed with.

remove the plugs see if they are wet or dry . also the fuel pump relay is under the hood not the dash , on the main relay box its a green relay . and on the front relay box its the speed relay its a black one , look under the front relay cover I believe its to the right if you are looking at the car from the front

Sorry I meant fuel pump fuse under the dash Is there a way to check if the relays are bad?

yes , jump the fuel pump using the diagnostic box and see if you are getting power back at the fuel pump. (plug)

im looking for pics in the forum and online of exactly what place to put the jumper wire but I cant find any clear pics.....help?

Just put a jumper on and unplugged the pump from the trunk. Turned the key on ad checked voltage at the pump and its only showing right around 6 volts.

pulled the main relay and EGI relay (don't even know what that does) from under hood and hooked them straight to the battery to see if they are working, and they are.

In my humble opinion you need to regroup here and look at the facts before you go off on fifteen different tangents.

The car was working fine before you worked on the radio, right?
You took out the radio and messed with a bunch of wires, some of which you never identified in your other post (about the radio)
You got the radio working but now the engine won't fire.
SOMETHING happened whilst you were working in the radio bay to make your car go from working to non-working.
To me, it sounds like you must have cut or otherwise compromised a wire or connection from the ignition switch that fires the coils and allows the car to come on.
You need to get some help (someone to crank the car or someone to hold a spark plug) and see if you have fire at the plugs. I'd bet the farm you don't.
If not, pull the radio again and look at every single wire and connector in the area and see if you've done something.

My bet is he moved it and flooded it haha. If you have a PowerFC, check for cranking RPM there. If not, check for spark like others have suggested. If you don't know how to do this an easy way to do this is pull the boot off and rest it over the spark plug so it will still arc and you can see the spark if its working while cranking. Don't have your hand near it unless your wearing thick gloves or you'll be in for a nice jolt.

I plan on pulling the radio back out today. I'm thinking maybe I pinched a wire somewhere when I pushed the radio back in. Do any of the wires for the fuel pump run thru the dash? Just trying to figure out why the pump is only getting approx 6 volts.. Gotta eliminate one thing at a time though like he said ^^

The pump gets less voltage at low RPM factory.

Got it running. When I put gas in it a few nights ago I put some oil premix in with the gas. I think I either put too much or it just settled to the bottom of the tank. After it started it smoked white smoke for about 5 minutes then burned off by I believe was the oil. Running fine now. So it's all good for now

Good to hear.

Might be a sign of the start of a coolant leak.

Ill keep an eye on it. I'm pretty sure it was the premix oil I put in the tank before I put gas in the car. I won't be doing that anymore Thanks guys
