New Fuel Pump, But NO FUEL???

I have been having fuel problems for the past month,
first I was told that a fuel line was crimped, then
I thought my fuel pump and relay was bad, Changed
those. Still have the problem. It seems as if there is a problem
with the wires that connect to the tops of the injectors.
When I have this problem occurs my fan doesn't work either.
What is it? Electical? Do I need a new harness? alternator?
Please help as this problem has robbed me of lots of money and
even more time

A friend of mine had the same problem, it ended up being the ECM. but before you do all that, pull out the fuel line going to the throttle body and have someone turn the key. If you get fuel you know the delivery system is good. If not check for a clogged filter and listen for the pump to kick on. If all is well and still no fuel from the injectors, get an injector test light from your local auto parts store, they're not much and it plugs right in to the injector plug. If you get no light check your fuses, if the fuses are good have someone check the ECM. If you get light your injectors are probably bad. Good luck and post your results.

Well I'm sure it's electrical since the fuel filter was changed along with the pump and relay. It starts sometimes, most of the time.
However I can't risk breaking down anymore. I'm not sure about
how to check the fuses, only the transparent ones or the silver backed breakers as well? What about my injector harness could that be it? I haven't checked my ecm yet, that is the thing that
sits behind the tbi on the passenger side correct?

Your ECM is under the kick panel on the passengers side inside the car. Get an injector test light and test that. It sounds like the direction to go in next. I believe what you are thinking of is the EGR.

Ur right, I was thinking of the egr. Well I had it towed into
a dealer last sat, and they really don't know what's up.
So I'll guess I'll get crackin myself.


thanx,

Try having someone crank it and shoot some starting fluid down the throttle body. That's an easy way to tell if you have spark if it tries to kick over. I still bet the ECM is gone. Find one in a junk yard cheap and swap them out unless you know someone that will let you swap the parts to check. It always helps to get to know your local parts people real good....

That was the first thing I tried it definetly kicks over but as
soon as that gas is used up it dies again.
