I thought you stated that there is fuel reaching the fuel rail? Atleast check your base timing, you may be surprised.

have you checked the VAM? I had one go out. it would crank but not fire. if you are getting spark then the EEC has to be getting power.

IMHO

If you have spark and are geting fuel to the rail... and the plugs are not wet.. There are 2 fundamentals you MUST check... all of which people have posted before.

1. You have to start reading the codes from the EEC. This will tell you if you have a bad TPS, VAM..... there are a few sensor issues that will stop it from starting. You can spends hours and many dollars without finding it... do this first and save yourself a nightmare..

2. You need to check the pressure in fuel rail.

3. Get a good EEC/Injection trouble shooting book.

It will be cheaper in the long run to buy the correct tools to read the codes ( get one of those cheap code scaners that comes with a code book ) and a presure gauge. These two tools are the basics you need for trouble shooting a EEC/Injected car.

Otherwise get ready to spends many more dollars and hours on parts you don't need.

One final item is that the fuel pump does not turn for longer then a second or two when the engine does not start. It runs only long enough to pressurize the fuel rail just enough to start the car.

It does not pump fuel with the key on and engine not running.

The test procedure is to turn the key on/off/on/off several times to check if the rail has been pressurized. This is where you need the pressure gauge.

If you do have pressure, then you move onto to....EEC codes.

Have you pulled the plugs to see if they are saturated with fuel after you turn it over? This hasn't been stated yet. This might be the best way to test out your injectors.

check the fuse links !! I had the same deal with my ranger. It shutdown like the TFI went south, Plugged in my trusty standby TFI still no good. After checking everything i found the fuse link by the steering column engine side of firewall was dead !!! it feeds the fuel pump relay [Image: biggrin.gif]

ok, just want to set a few things strait. THE CAR DOES NOT GET FUEL!!! Please read the whole post. MY problem is the LACK OF FUEL. I don't mean to sound like a a$$ or anything, but some of these ideas would work great if it was getting fuel, but it isn't. The only time my rail gets fuel is if I hook the fuel pump up strait to the battery. but then the injectors aren't shooting fuel into the engine. you must remeber, THE CAR DOES START WITH STARTING FUILD AND RUNS FOR LIKE 2 SECONDS.

On the ECC codes part. I tried to get the codes. I'm going to have to get a nice code read to see if that will pull them. I tried to do it through the check engine light and a test light/volt meter and I couldn't get it to work.

Just a thought...

You say you are gettin no fuel. Pump will not turn on. Car will run with "sunny juice" And there is power to the pump?

Have you ever thought to check the pump to see if it actually works? What I mean is how did you install the pump? Did you solder the wires or crimp them? In my car I had the whole thing already assembled. I am not familiar with the BBK one (I have a Holley) but are the connections inside the tank connected? And do you have a second pump you can switch into the car to see if this is your problem?

You know it is a no fuel problem so start at the source.

If the VAM door is jammed open for some reason, it won't start and will show all those symptomes. Unplug the VAM and and try to start it. This one had me pulling my hair out for a weekend once.

will try the VAM idea, I know it isn't the pump because if I hook it up to a 12V source, it turns on.
