Need help... Car starts for 10 seconds then dies

[$STEALTH$]

My 93 dodge stealth R/T DOHC non turbo wont stay running. I have a toggle switch for the fuel pump ran inside the car. I can flip the switch on for a minute and let it build pressure. Then it starts right away. But then it dies. As if the fuel just gets cut off or something. The car has this weird security system in it. VPS or Vehicle Protection Systems. It is hooked up to some wires below the dash over by the fuse box. Then it has a wire run to this input thing under the dash. (You can see it while sitting in the car, its not hidden) It has a little thing that you stick into it. The part it self flashes red. Until i stick the key into it. The car wont start without it in there. its all connected to this VPS thing. And when it does start. It will idle for about 5 to 10 seconds and then the car will completely die on me. I put in a used fuel pump and sending unit that works. I tested it before i put it in. I also took off the fuel line where it plugs into the fuel rail. The fuel is getting to it great. Some people are saying that i need an upgraded fuel pump. Or my fuel pressure regulator is shot.

Im not sure if this has something to do with the cars computer. Which i think something is going out. I used to be able to flip up my lights when the car was completly off. The door used to ding. Dome lights used to come on. Cant get my CDs out of the CD changer in the back. The stereo has no memory when i turn the car off for 10 seconds then turn it back on. Its reset again... I dont know what to do??....

Today i started the car. It ran for about 5 seconds. Then i heard a click. and the engine killed. What is that? It ran awesome for those few seconds though. everything in the car stays on. But the engine kills. i think its coming from the computer. Now im just starting to assume its the VPS (Vehicle Protection Systems) as i said i hear a click. And the engine completely just stops. shuts off. Its not a fuel problem i know that now.

Could you please help out or give an opinion if you read this post. Thank you

CAR STARTED AGAIN! But then died. But.... I found out where the clicking is coming from. My computer or one of the relays down there on the floor by the computer. I think the security system is connected to the computer somehow.

Okay so i found out for sure where the clicking is coming from. Its this golden box on the passenger side by the computer. I think my security system has to be hooked up to that somehow. There is two relays on the left side that are not even working or getting power to them.

It is the Main Control Relay that is making the ticking noise. I tried to unplug it and start the car. Nothing happend. Car only starts when i have that plugged in. I read somewhere on the internet some guy took his apart and pinned the shut off relay inside it and his car ran fine. This car is just pissing me off. Im trying to get it ready for the 3SI meet. Somebody please help

maybe try replacing the relay?

first try unplugging the mass and starting it. If it stays running, but has a crappy idle, you may need a MAS.

have you replaced the caps in the ecu yet?
if not, pull the ecu to check the caps.
the wiki for this on 3si can be found here
as autostrada suggested, disconnect the MAF sensor and start the engine to see if it stays running.
if it does, you either have a vacuum leak somewhere or the MAF sensor is toast.
checking the fuel pressure would not hurt either, just to make sure the pressure regulator is working properly.
at the mfi relay that you found on the right side of the console test the black/yellow wire for about 12v while cranking and once started the white/red wire should for ground.
the black/yellow wire engages the relay for your fuel pump while crank and the white/red keeps it going once it starts.
if you do not get ground on the white/red after it starts, i would suspect the ecu.
if this is the case, it is highly likely that your caps made need to be replaced if it hasn't damaged the board yet.

I have not replaced or checked the ECU caps yet. I just tryed starting the car with the MAF off and it would not stay running. Car killed instantly. The main control relay still clicks the car off

Yesterday i let the car roll to the bottom of the driveway. Its about a 30 foot driveway. And i started it up and moved it to the top of the driveway then it shut off. If that helps at all??

[$STEALTH$]

the car is completely stock. besides a cold air intake on it. It is spitting oil out of the exhaust now? the car does not run bad? It idles awesome though. I will check my ECU tomorrow after work and write back on here what my diagnosis is. Thank you guys for helping. Please continue to help some more. I really would like my car working

the car should not run with the relay disconnected, so that is normal.

Well i took apart my computer. Nothing has leaked onto the board. So it must not be my computer. It looks fine. The caps are all in good condition.

The manual suggest that the following components be check in order, if the engine fires and than dies:

Fuel Pump
Injectors
Engine coolant temp sensor
Ignition switch
Idle air control motor
Fuel pressure
Camshaft position sensor
Crankshaft position sensor

For your electrical problems, check all of the fuses in both fuse boxes. Even if you find one bad, check the rest to make sure you don't have any others.

Is there a way to check all of those??? Well my fuel pump works because i have a hot wire hooked up to it. But if i dont have that hooked up it wont work. My injectors are working i think. Because the car will stay running. Its getting all the fuel it needs. Engine coolant temp sensor i have no clue how to check. or the rest on down

and where would all of those be? I just found what looks to be a computer box on the passenger side. By the door. What is that too? What is it called?
